ENGLISH ABSTRACT: This study investigated the comprehension and production of articles, quantifiers, binding relations and passive constructions as later developing constructions (LDCs) by 27 Grade (Gr) 1 monolingual Afrikaans-speaking learners with Afrikaans as language of learning and teaching (LOLT), 31 bilingual isiXhosa-speaking learners with English as LOLT and 31 monolingual isiXhosa-speaking learners with isiXhosa as LOLT in three non-fee-paying schools, each in a different low socio-economic status area, in the Stellenbosch area of the Western Cape Province in South Africa. The overarching aim of this study was to determine which LDCs these learners are capable of comprehending and producing at the start of Gr 1 and what progress they make in terms of these LDCs during their Gr 1 year. The English and isiXhosa LOLT groups were then compared on how they fared on the LDCs in their respective LOLTs in order to ascertain whether the English language proficiency of the English group is at such a level at the start of Gr 1 that they can, without disadvantage, undergo schooling successfully in English. Data were collected on articles, binding relations, quantifiers and passive constructions by using the informal language assessment instrument, the Receptive and Expressive Activities for Language Therapy (Southwood & Van Dulm 2012a), which makes use of picture selection- and pointing tasks for assessment of comprehension and sentence completion, picture description- and question answering tasks for assessment of production. The results showed that for the Afrikaans and English groups all four LDCs are indeed later developing and are only mastered after the end of Gr 1. For the isiXhosa group, quantifiers and passive production are mastered by the end of Gr 1. In terms of the language-in-education and teaching policy, the results show that the time allocated to listening to and producing language in Gr 1 is sufficient for children whose first language is also their LOLT, whereas it is not sufficient in the case of English additional language learners. The latter group made significant progress in all LDCs assessed, but still performed worse than their isiXhosa-speaking peers, for whom there was a match between first language and LOLT. The implication of the results are that (i) the Foundation Phase school curriculum should be refined so as to consider the needs of all Gr 1 learners, as learners enter Gr 1 with different language skills and different levels of preparation for the tasks which lie before them, (ii) teachers should be assisted to foster the development of language skills in additional language learners, and (iii) the institution of a universal Gr R year, which is free to those who cannot afford school fees, should be considered a necessity. Without ensuring that all children enter Gr 1 with an adequate language foundation on which literacy development can build, historical inequalities still present in South Africa will likely be perpetuated rather than systematically removed.
AFRIKAANSE OPSOMMING: Hierdie studie ondersoek die begrip en produksie van lidwoorde, kwantifiseerders, bindingsverhoudings en passiefkonstruksies as later-ontwikkelende konstruksies (LOKs) deur Graad 1 (Gr 1)-leerders. Die deelnemers was 27 eentalige Afrikaanssprekendes met Afrikaans as taal van leer en onderrig (TLO), 31 tweetalige isiXhosa-sprekendes met Engels as TLO en 31 eentalige isiXhosa-sprekendes met isiXhosa as TLO, in drie nie-skoolfondsbetalende skole, elk in 'n ander area met lae sosio-ekonomiese status in die Stellenbosch-omgewing in die Wes-Kaap Provinsie van Suid-Afrika. Die oorkoepelende doel van hierdie studie was om te bepaal watter LOKs hierdie leerders in staat is om te verstaan en te produseer aan die begin van Gr 1 en watter vordering hulle in terme van hierdie LOKs maak tydens hul Gr 1-jaar. Die Engelse en isiXhosa TLO-groepe is vergelyk in terme van hoe hulle gevaar het op die LOKs in hul onderskeie TLOs, ten einde vas te stel of die Engels-taalvaardighede van die Engelse TLO-groep op so 'n vlak aan die begin van Gr 1 is dat hulle sonder benadeling hul skoolopleiding suksesvol in Engels kan ontvang. Data is ingesamel oor lidwoorde, bindingsverhoudings, kwantifiseerders en passiefkonstruksies met die informele taalassesseringsinstrument, die Reseptiewe en Ekspressiewe Aktiwiteite vir Later-ontwikkelende Taalvaardighede (Southwood & Van Dulm 2012a), wat gebruik maak van prentseleksietake vir die assessering van taalbegrip en van sinsvoltooiings-, prentbeskrywings- en vraagbeantwoordingstake vir die assessering van taalproduksie. Die resultate het aangetoon dat al vier LOKs wel later ontwikkelend is vir die Afrikaanse en Engelse TLO-groepe en slegs bemeester word ná die einde van Gr 1. Vir die isiXhosa-groep is kwantifiseerders en passiefproduksie teen die einde van Gr 1 bemeester. Gegee die taal-in-onderwys- en onderrigbeleid toon die resultate dat die tyd wat toegeken is aan die ontwikkeling van luister- en taalproduksievaardighede in Gr 1 voldoende is vir kinders wie se eerste taal ook hul TLO is, terwyl dit onvoldoende is in die geval van Engels Addisionele Taalleerders. Laasgenoemde groep het beduidende vordering gemaak oor hul Gr 1-jaar in alle LOKs, maar het steeds swakker gevaar as hul isiXhosa-sprekende eweknieë wie se eerste taal en TLO ooreenstem. Die implikasies van die resultate is (i) dat die grondslagfase-skoolkurrikulum verfyn behoort te word met inagname van alle Gr 1-leerders se taalbehoeftes, omdat leerders Gr 1 betree met verskillende taalvaardigheidsvlakke asook verskillende vlakke van voorbereiding vir die take wat voorlê in Gr 1, (ii) dat onderwysers gehelp moet word om die ontwikkeling van taalvaardighede vir Addisionele Taal-leerders te bevorder, en (iii) dat die instelling van 'n universele Gr R-jaar, gratis vir diegene wat nie skoolfonds kan bekostig nie, as noodsaaklik beskou behoort te word. As daar nie verseker word dat alle kinders Gr 1 betree met ‘n voldoende taalbasis waarop geletterdheidsontwikkeling kan bou nie, sal historiese ongelykhede, steeds teenwoordig in Suid-Afrika, waarskynlik eerder voortgesit as stelselmatig verwyder word.

This research examines whether a seven-year-old nonverbal boy's comprehension of syntax develops at an accelerated rate following the introduction of speech output through a portable speech synthesizer (VOIS 135). The study was motivated by (1) a general lack of agreement about the relationship of comprehension and production in language acquisition, (2) some child language investigators' claims that--at certain points during the development of language--production precedes and influences comprehension, and (3) the natural experimental condition provided by a nonverbal child who is suddenly given the ability to 'speak' with the help of a portable speech synthesizer. At the beginning of the research period, the child's sentence comprehension was thoroughly assessed with standard and special purpose tests. His production was assessed through analysis of videotaped interactions. The child was then trained to use the synthetic speech device (VOIS 135) over an eight month period. At the end of this period testing of both comprehension and production was repeated to provide a measurement of language growth in each performance mode. The child demonstrated comprehension of concatenated structures and clefts at the end of the research period; this represented a developmental leap from the beginning of the research period when he understood only much simpler structures. During the eight month study, development of comprehension on the lexical level came to an apparent halt. Production results indicated that the child experienced a definite expansion in productive vocabulary and length of utterance during the research period. Observations indicated that the child's pragmatic and discourse skills improved markedly with his use of the speech output device. Factors which might account for developments (or lack of development as in the case of lexical comprehension) are discussed. Clinical implications of improvements in pragmatic and discourse skills through the use of the device are considered along with methodological suggestions for using this study as a pilot for larger research. Conclusions are that: (1) use of the speech synthesizer led the child to listen to utterances as structural wholes; (2) the child became a more active and independent partner in the communication exchange; (3) synthetic speech garnered the child more attention and more opportunities for interaction; (4) synthetic speech gave the subject access to a greater range of communication partners. While the comprehension-production results are interesting, i.e. the child was able to understand structures at a level of unanticipated complexity after being trained to use the speech device, these results do not elucidate the nature of the comprehension-production relationship. Difficulties in interpreting the results of this study underline the need for a coherent theory relating comprehension and production in language development.

The current thesis presents the differential profiles of Italian and Greek dyslexic and typically developing children on a series of language tests, tapping both production and comprehension abilities. By highlighting the differential profiles of dyslexic children on a series of language tasks that include structures that have been found to be particularly vulnerable in Specific Language Impairment, the current thesis aims to assist the processes of differential diagnosis, to serve as a base for further investigation of the differences between the two disorders, as well as to contribute to the development of rehabilitation material. The tests that have been implemented focused on the production and comprehension of direct, indirect object clitics, definite articles and wh-questions through elicited production, sentence-picture matching and grammaticality judgment tasks. Moreover, an additional task on the comprehension of wh-questions through meta-syntactic facilitation was introduced. Finally, the results obtained by Greek-speaking children with Specific Language Impairment are presented, again, with an emphasis on the different performance profiles between SLI and typically developing children, as well as on the potential differentiating patterns between typically developing, SLI and dyslexic children.

Although language usually occurs in an interactive and world-situated context (Clark, 1996), most research on language use to date has studied comprehension and production in isolation. This thesis combines research on comprehension and production, and explores the links between them. Its main focus is on the coordination of visual attention between speakers and listeners, as well as the influence this has on the language they use and the ease with which they understand it. Experiment 1 compared participants’ eye movements during comprehension and production of similar sentences: in a syntactic priming task, they first heard a confederate describe an image using active or passive voice, and then described the same kind of picture themselves (cf. Branigan, Pickering, & Cleland, 2000). As expected, the primary influence on eye movements in both tasks was the unfolding sentence structure. In addition, eye movements during target production were affected by the structure of the prime sentence. Eye movements in comprehension were linked more loosely with speech, reflecting the ongoing integration of listeners’ interpretations with the visual context and other conceptual factors. Experiments 2-7 established a novel paradigm to explore how seeing where a speaker was looking during unscripted production would facilitate identification of the objects they were describing in a photographic scene. Visual coordination in these studies was created artificially through an on-screen cursor which reflected the speaker’s original eye movements (cf. Brennan, Chen, Dickinson, Neider, & Zelinsky, 2007). A series of spatial and temporal manipulations of the link between cursor and speech investigated the respective influences of linguistic and visual information at different points in the comprehension process. Implications and potential future applications are discussed, as well as the relevance of this kind of visual cueing to the processing of real gaze in face-to-face interaction.

The purpose of this study was to examine the relationship between language skills and prosocial behavior in 37 children with language impairment (LI) and 37 typically developing peers matched for age (ranging from 6;11 to 11;1 years). The influence of gender on this relationship was also considered. Three different subtests of the Comprehensive Assessment of Spoken Language (Carrow-Woolfolk, 1999) were used to evaluate language ability in the areas of language comprehension, language production and pragmatic judgment skills. The Teacher Behavior Rating Scale (C. H. Hart & Robinson, 1996) was used to evaluate prosocial behavior. The current study replicated previous research by documenting that children with LI demonstrate significantly poorer prosocial behavior skills than do typically developing peers. Children with LI also performed significantly more poorly on the three language subtests of paragraph comprehension, syntactic construction, and pragmatic judgment skills compared to typical peers. No significant gender differences were noted on any of the comparisons. Multiple regression analyses were used to evaluate the relationship between the three language subtests and prosocial behavior in the group with LI compared to the typical group. Results for both groups indicated that paragraph comprehension, syntactic construction, and pragmatic judgment skills were not significant predictors of prosocial behavior when used in combination or independently. Results suggest that language alone cannot predict prosocial behavior in children with LI or typically developing children.

The aims of this study were i) to evaluate the domains of language production, comprehension and naming in children with moderate or heavy prenatal exposure to alcohol, and ii) to determine if these domains are a specific weakness in these children. The study compared 25 children with FASD to 25 typically developing non-alcohol exposed controls on four language measures; (1) the Clinical Evaluation of Language Fundamentals Revised; (2) the Test of Reception of Grammar- Version II; (3) the Cookie Jar Theft Picture test and; (4) the Boston Naming test.

The purpose of this dissertation is to empirically test the hypothesis that children's omission of functional elements reflects performance factors (McKee, 1994; McKee & Iwasaki, 2001), rather than lack of knowledge (Felix, 1987; Radford, 1990, 1995; Tomasello, 2000). The multi-level production system treats content and function morphemes differently (Garrett, 1982). Further, a function morpheme's free or bound status and the independence of the content stem affect the likelihood that a function morpheme will be omitted. Four experiments each employed production and comprehension tasks testing English- and Icelandic-speaking children's and adults' production and comprehension of different prepositional phrases. The English experiments tested prepositional phrases with content prepositions and content/function preposition combinations. The Icelandic experiments tested prepositional phrases with prepositions and their associated case markings. Function prepositions in English and case markings in Icelandic both convey information about case, with the former being a free function morpheme, and the latter a bound function morpheme. Both English- and Icelandic-speaking children showed comprehension of prepositions that they do not produce. Further, Icelandic-speaking children produced case markings but English-speaking children did not produce function prepositions. These findings support a performance-based hypothesis with omission attributable to coordination issues among elements in the multi-level production system. These findings also show the importance of cross-modality and cross-linguistic research in studying the competence of children before, during, and after the telegraphic speech stage.

This research was designed to provide information concerning the developmental differences in early language production and comprehension between 21 month-old first born and second born children. Furthermore, the study explored the assumption that more opportunities to hear conversations between the parent and the older sibling provide an advantage for second born children in learning personal pronouns.
Spontaneous speech productions of 16 first born children were compared to those of 16 second born children while in dyadic interactions with their mothers. First born children were observed in two 25 minute free-play dyadic interactions with their mothers. Second born children were observed in one 25 minute free-play mother-child dyadic interaction and in one 25 minute free-play mother-child-older sibling triadic interaction. All children were administered controlled tasks involving production and comprehension of first and second person pronouns.
Compared to first borns, second born children are not significantly delayed in general language development. Second borns' speech productions differ depending on whether or not their older sibling was present. (Abstract shortened by UMI.)

Mastery of idioms in a second language is an important part of learners' lexical and cultural competence. This study provided insights into the processes that partake in interlanguage idiomatics. It also looked at the role of participants' first language in the comprehension and production of idioms in their second language. Participants were 31 Saudi graduate students' who were learners of English. They were tested in receptive and productive knowledge of 15 English idioms of three types of idiomatic expressions: a) English idioms which have their exact equivalents in Arabic; b) English idioms which are similarly expressed in both languages, and c) English idioms which have no counterparts in Arabic. The data were examined through statistical analysis. Results showed that identical idioms were the easiest to comprehend and produce, followed by similar idioms. Different idioms were the most difficult to comprehend and produce and showed the highest interference from the first language. In addition, a rather unexpected negative correlation was found between participants' length of stay in the US and their knowledge of English idioms. These findings offer insightful implications for the teaching and learning of second language idioms. Most importantly language teachers and researchers should be aware that the acquisition of idioms is influenced by the similarities and differences between idioms in learners' L1s and the target L2. This suggests that building learners' idiomatic knowledge in a second language should be done in a systematic and persistent way. In more general terms, the study's results confirm the trends and patterns reported in previous research about the acquisition of second language idiomatic competence and its important role for the effective comprehension and production of the target language.

This thesis investigates the mechanisms that underlie the interaction of gesture and speech during the production and comprehension of language on a temporal and semantic level. The results from the two gesture-speech production experiments provide unambiguous evidence that gestural content is shaped online by the ways in which speakers package information into planning units in speech rather than being influenced by how events are lexicalised. In terms of gesture-speech synchronisation, a meta-analysis of these experiments showed that lexical items which are semantically related to the gesture's content (i.e., semantic affiliates) compete for synchronisation when these affiliates are separated within a sentence. This competition leads to large proportions of gestures not synchronising with any semantic affiliate. These findings demonstrate that gesture onset can be attracted by lexical items that do not co-occur with the gesture. The thesis then tested how listeners process gestures when synchrony is lost and whether preceding discourse related to a gesture's meaning impacts gesture interpretation and processing. Behavioural and ERP results show that gesture interpretation and processing is discourse dependent. Moreover, the ERP experiment demonstrates that when synchronisation between gesture and semantic affiliate is not present the underlying integration processes are different from synchronous gesture-speech combinations.

Slowness in rapid naming of visual stimuli is a typical problem of both Specific Language Impairment (Miller et al., 2001; Kleemans et al., 2012; McGregor et al., 2002) and Developmental Dyslexia (Swan & Goswami, 1997). Moreover, longitudinal studies (Wolf & Obregon, 1992) confirm the association between image naming deficits in kindergarten and the occurrence of a subsequent reading disorder, showing a particular correlation between slowness in naming tasks and text decoding difficulties, rather than text comprehension difficulties. In this study, a group of Italian dyslexic children with and without SLI were compared with an age-matched group of typically developing children on tasks of rapid naming, written decoding, reading and syntactic comprehension, and clitic production, in order to identify differences and correlations between performances of differently impaired subjects. The theoretical framework was only partially confirmed. The results were interpreted in light of the Double Deficit Hypothesis (Wolf & Bowers, 1999; Wolf & Obregon, 1992, 1997), which was supplemented with a psycholinguistic hypothesis supporting multifactor models of learning disorders.

From the perspective of cognitive psychology, our knowledge of language can be viewed as mental representations and our use of language can be understood as the computation or processing of mental representations. This thesis explores the mental representation and processing of syntactic structure. The method used in this thesis is structural priming, a phenomenon in which people tend to repeat the linguistic structure that they have recently processed. The language under investigation is Chinese. The main research theme is divided up into four different questions. The first question is how syntactic structure is mentally represented. For a long time this has been a question for syntacticians whose main evidence is their intuition. There are, however, recent calls for experimental methods in the investigation of syntactic representation. I propose that structural priming can be used as an experimental approach to the investigation of syntactic representation. More specifically, structural priming can illuminate the constituent structure of a syntactic construction and help us determine which syntactic analysis corresponds to the representation of the construction. Three structural priming experiments on some controversial constructions in Mandarin were reported to show that structural priming can be used to distinguish alternative analyses of a syntactic construction. The second question concerns the use of thematic and lexical information in grammatical encoding in sentence production. Models of grammatical encoding differ in the locus of conceptual effects on grammatical encoding and the extent to which grammatical encoding is lexically guided. Five experiments were reported on these two issues. First, the results indicate that thematic information affects grammatical encoding by prompting the processor map thematic roles onto the same linear order as they were previously mapped. Though conceptual information was previously believed to only affect the assignment of grammatical functions (e.g., subject and object) to nouns (i.e., functional processing), this finding suggests that it can influence the linear order of sentence constituents (i.e., positional processing) as well. The results also show that the processor persists in using the same argument structure of the verb, implying that grammatical encoding is lexically guided to some extent. The third question concerns the processing of verb-phrase (VP) ellipsis in comprehension. Previous research on this topic disagrees on whether the interpretation of VP ellipsis is based over the syntactic or semantic representation of the antecedent and whether the antecedent representation is copied or reconstructed at the ellipsis site. An experiment was presented and the results show no structural priming effect from the ellipsis site. This suggests that no syntactic structure is reconstructed at the ellipsis and possibly no copying of the antecedent structure either. The results then favour a semantic account of VP ellipsis processing. The last question concerns the lexico-syntactic representation of cognates in Cantonese-Mandarin bilinguals. Previous research has paid little attention as to whether cognates have shared or distinct lemmas in bilinguals. Two experiments show that the structural priming effect from the cognate of a verb was smaller than from the verb itself, suggesting that Cantonese/Mandarin cognates have distinct rather than shared lemmas, though the syntactic information associated with cognates is collectively represented across the two languages. At the end of the thesis, I discussed the implications of these empirical studies and directions of further research.

How do bi/multilinguals switch between languages so effectively that there is no obvious intrusion from the alternatives? One can examine this by comparing language selection with task selection, or language switching with task switching. This is the approach adopted in the first of two strands of research presented in this thesis. In task switching, providing advance warning of the task typically leads to a reduction in the performance ‘switch cost’, suggesting top-down biasing of task selection. It is not clear whether the language switch cost also reduces with preparation, partly because there have been very few attempts to examine preparation for a language switch, and partly because these attempts suffered from non-trivial methodological drawbacks. In Experiments 1-3 I used an optimised picture naming paradigm in which language changed unpredictably and was specified by a language cue presented at different intervals before the picture. Experiment 1, conducted on ‘unbalanced’ bilinguals, revealed some evidence of reduction in the language switch cost for naming times with preparation, but only when cue duration was short. In an attempt to further optimise the paradigm, in Experiment 2 the cue-stimulus interval (which was varied from trial to trial in Experiment 1), was varied over blocks instead. Visual cues were replaced with auditory cues – the latter also enabled a comparison between semantically transparent word cues (the spoken names of the languages) and less transparent cues (fragments of national anthems). Experiment 2 revealed a reduction in switch cost with preparation for naming latencies, but only in the second language; the first language showed the reverse. To examine whether the increase in switch cost with preparation in the first language could be due to unbalanced bilinguals biasing processing towards L2, balanced bilinguals were tested in Experiment 3. This revealed a robust reduction in switch cost in naming latencies for both languages, which was driven primarily by the trials with the anthem cues. However, in the error rates the switch cost increased with preparation interval, thus complicating the interpretation of the reduction observed for response times. Experiment 4 investigated whether preparation for a language switch elicits the electrophysiological patterns commonly found during preparation for a task switch – a switch-induced positive polarity Event-Related Potential (ERP) with a posterior scalp distribution. Contrary to a recent report of the absence of the posterior positivity in language switching, it was clearly present in the present EEG data. As in task switching, the amplitude of the posterior positivity predicted performance. The electrophysiological data suggest that preparation for a language switch and preparation for a task switch rely on highly overlapping control mechanisms. The behavioural data suggest that advance control can be effective in language switching, but perhaps not as effective as in task switching. Experiments 1-3 also examined the effect of stimulus associative history – whether the language used on the previous encounter with a given stimulus influenced performance on the current trial). Having previously named a given picture in the same language benefited overall performance, but did not do so more for switches than repeats. Thus, stimulus associative history does not seem to contribute to the language switch cost. The second strand of my research asked whether bilinguals can set themselves independently for speech vs. comprehension. Previous research has examined the cost of switching the language in output tasks and in input tasks. But, it is not clear whether one can apply separate control settings for input and output selection. To investigate this, I used a paradigm that combined switching languages for speech production and comprehension. My reasoning was that, if there is cross-talk between the control settings for input vs. output, performance in one pathway should benefit if the language selected for the other pathway is the same relative to when it is different: a ‘language match effect’. Conversely, if there is no cross-talk, there should not be a language match effect. In Experiment 5 bilinguals alternated predictably between naming numbers in their first and second language (in runs of 3 trials), whilst also having to semantically categorise spoken words which occasionally (and unpredictably) replaced the numbers. The language of the categorisation ‘probes’ varied over blocks of ~17 naming runs, but was constant within a block. The results showed a clear match effect in the input task (categorisation), but not the output task (naming). To examine the potential role of proficiency, Experiment 6 used the same paradigm to test unbalanced and balanced bilinguals. The pattern of results was qualitatively similar in both groups to that observed in Experiment 5: a language match effect confined to the input task. These results suggest ‘leakage’ from the output control settings into the input control settings.

With the increasing prevalence of voice-production technology across societies, clear comprehension while listening to synthetic speech is an obvious goal. Common human factors influences include the listener's language familiarity and age. Production factors include the speaking rate and clarity. This study investigated the speaking comprehension performance of younger and older adults who learned English as their first or second language. Presentations varied by the rate of delivery in words per minute (wpm) and in two forms, synthetic or natural speech. The results showed that younger adults had significantly higher comprehension performance than older adults. English as First Language (EFL) participants performed better than English as Second Language (ESL) participants for both younger and older adults, although the performance gap for the older adults was significantly larger than for younger adults. Younger adults performed significantly better than older adults at the slow speech rate (127 wpm), but surprisingly at the medium speech rate (188 wpm), both age groups performed similarly. Both young and older participants had better comprehension when listening to synthetic speech than natural speech. Both theoretical and design implications are provided from these findings. A cognitive diagnostic tool is proposed as a recommendation for future research.

Prepositions are acquired at earliest during the second year of life. This thesis investigates 16 children acquiring Swedish spatial prepositions, i.e. på ‘on/at’, i ‘in/at’, under ‘under’, bredvid ‘beside/next to’, bakom ‘behind/back’ and framför ‘in front’. This thesis aimed toinvestigate how preposition acquisition relates to language acquisition. The thesis used three different methods: eight sessions of free parent-child interaction, one structured experiment at 2;9 years and parental reports on child passive/active vocabulary from when the children were 0;9 years until they were 3;0 years old. The data gathered was correlated to scores in the parental reports at 4;0 years, which was used as a measure of communicative level, and used as a base when dividing the children into three groups: lower, average and higher score. The results showed that both parental and child preposition production, comprehension at 2;9 years, and comprehension and production predicted communicative level at 4;0 years. The results of the thesis varied depending on the method used. This highlights the importance if using several methods when investigating child language acquisition.
Prepositioner tillägnas som tidigast under barnets andra levnadsår. I denna masteruppsats undersöks utvecklingen av spatiala prepositioner hos 16 barn under deras 4 första levnadsår. På, i, under, bredvid, bakom och framför var prepositionerna som undersöktes. Ett av uppsatsens mål var att undersöka om och/eller hur prepositionsutveckling är kopplat till språkutveckling. För att nå målet användes tre olika metoder: åtta sessioner av förälder-barn interaktion, ett semi-strukturerat test då barnen var 2;9 år gamla och aktivt/passivt ordförråd från när barnen var 0;9 år till att de var 3;0 år gamla. Detta korrelerades sedan till barnens poäng från en föräldraenkät om barnets språkförmåga vid 4;0 års ålder. Poängen vid 4-års ålder låg till grund för uppdelning av barnen i tre grupper: lägre, medel och högre språklig nivå. Resultaten från uppsatsen var bland annat att såväl föräldrars som barns produktion av prepositioner, barnens förståelse av prepositionerna vid 2;9 år, och förståelse såväl som produktion av prepositioner förutsäger barnens kommunikationsnivå vid 4;0-års ålder.  Resultaten skiljer sig beroende på vilken metod som använts, vilket understryker vikten av att använda flera metoder när barns språkutveckling undersöks.
MINT - moduling infant language acquisition from parent-child interaction

Denna studie undersöker om dold språkförståelse i ett andraspråk kan synliggöras vid återberättande på förstaspråket. Det kan vara svårt att skilja språkutvecklingen hos barn med typisk språkutveckling med svenska som andraspråk från språkutvecklingen hos flerspråkiga språkstörda barn om man testar dem på andraspråket. Därför behövs det referensdata för normalspråkiga barn. Sexton barn i femårsåldern med normal språkutveckling, åtta enspråkiga barn med svenska som första språk och åtta flerspråkiga barn med arabiska som första språk och svenska som andraspråk, testades med Buss-sagan (Buss Story Test, BST) och TROG (Test for Reception of Grammar). De flerspråkiga barnen fick sagan uppläst på svenska och återberättade först på svenska och sedan på arabiska. Resultatet i den kvantitativa analysen visade att de enspråkiga barnen fick signifikant bättre resultat för parametern information på BST och bättre resultat på TROG. Däremot skiljde sig resultatet för parametern information i berättelserna på arabiska inte signifikant från resultatet i de flerspråkiga barnens berättelser på svenska. Den kvalitativa analysen visade att de flerspråkiga barnens återberättelser på svenska och arabiska jämfört med de enspråkiga barnens framför allt lexikalt och diskursivt var mindre komplexa och korrekta. Detta kan till viss del bero på testsituationen, men också på brister i språkförståelse och uttrycksmedel. Slutsatsen man kan dra är att man som logoped behöver vara medveten om att olika språkliga strukturer utvecklas i olika takt både i första- och andraspråket, och att det behövs anpassat inflöde på alla språk för att underlätta språkförståelsen och den lexikala utvecklingen.
This study examines if language comprehension which may be concealed in a second language can be made visible by retelling in the first language. It can be difficult to separate the language development of typically developed children with Swedish as their second language from that of multilingual children with language impairment. Therefore, reference data for multilingual children with typical language development are needed. Sixteen five-year-old children with normal language development, eight monolingual children with Swedish as their first language and eight multilingual children with Arabic as their first language and Swedish as their second language, were tested with Buss Story Test (BST) and TROG (Test for Reception of Grammar). The multilingual children got the story of Buss Story Test read to them in Swedish and then retold the story first in Swedish and then in Arabic. The result of the quantitative analysis showed that monolingual children achieved significantly better results for the parameter information on BST and better results on TROG. On the other hand, the result of the parameter information in the children’s Arabic retellings did not differ significantly from that in the multilingual children’s Swedish retellings. The qualitative analysis showed that the multilingual children’s retellings in Swedish and Arabic compared with the monolingual children’s retellings were less complex and correct in regard mostly to lexical and narrative structure. This can, to a certain extent, be due to the testing situation, but also due to deficiencies in language comprehension and means of expression. The authors conclude that speech therapists need to be aware of the fact that different linguistic structures develop at a different rate both in the first and the second language, and that tailored input in all the children’s languages is needed in order to facilitate comprehension and lexical development.

M. is a 14-year-old student in his second year of high school. In spite of his clear difficulties in following a regular program, he has been included in a normal classroom. According to the Italian legislation he is a student with Special Educational Needs (SEN in the UK; Bisogni Educativi Speciali BES in Italy), therefore a specific teaching plan has been modeled on him at the beginning of his high school career. The plan does not consider his difficulties in detail. Focusing only on the distinction between dyslexia and Specific Language Impairment (SLI), the aim of this thesis is to investigate his language impairment through the submission of standardized tests (Peabody PPVT-R, Test di Comprensione Grammaticale per Bambini TCGB and Prove di Valutazione Grammaticale dell’Italiano Scritto) and non-standardized tests (Sentence repetition task, Passive sentence comprehension task, Passive sentence production task and Relative clause comprehension task). The analysis of his performance in the standardized tests made it possible to detect poor vocabulary skills; difficulties with negative, relative and dative sentences; low accuracy in the use of pronouns, articles and prepositions. Non-standardized tests revealed that memory and passive sentences are more preserved than relative clauses. The analysis and the comparison of results with normative data highlight that M.’s impairment is more probably related to SLI and that the plan stated by the school board is not adequate to his needs.

Normally hearing children with ASD are often reported to have a lack of interest in others, particularly when looking at faces, as a result of this they manifest difficulties understanding and using facial expressions compared to typically developing controls. Deaf children often show advantages with the processing of the face, as they need to look to the face more to communicate, due to the presence of linguistic facial expressions in British Sign Language (BSL). It is unknown how deaf individuals with ASD will fare when processing faces. This is the first study to look at how deaf children with ASD compare to typically developing deaf controls on a face processing measure and a number of comprehension and production measures looking at affective and linguistic facial actions in BSL. Surprisingly the deaf ASD group showed no general face processing impairment or difficulty attending to the face for the purpose of communication, they did not show characteristics usually associated with hearing individuals with ASD. This suggests the extra experience gained from attending to faces may reduce face processing impairments in deaf individuals with ASD. More research is needed to warrant this conclusion. The deaf ASD group did demonstrate specific impairments with the comprehension and production of some affective facial expressions in BSL. Linguistic facial expressions were largely preserved, with the exception of adverbials. The impairments that emerged in the deaf ASD group were most pronounced when production or comprehension of the face required attributions about the mental states of others. These results suggest that deaf individuals with ASD are not impaired with face processing, rather they have a highly specific and subtle pattern of impairments with using the face in sign language.

The aim of this report is to investigate how often and how computers are used during Spanish as foreign language classes regarding reading comprehension and written production. Our intentions are also to compare elementary schools and upper secondary schools, as well as to investigate if there are any diferencies between the perceptions of the teachers and the pupils.   We have mainly based our study on the theories of Acquaroni Muños and Cassani i Comas. They both have written articles about reading comprehension and written production.  Regarding computers and their functions the articles of Ruipérez García and Higueras García have a great significance.   We have chosen to use a quantitative method, in form of questionnaires. We have created one questionnaire for the students and another one for the teachers. The questionnaires were carried out in two different upper secondary schools and in one elementary school in the southwest of Sweden. The students’ questionnaire contains 64 questions while the teachers’ questionnaire contains 60 questions.   Our hypothesis was that the computer is not used while teaching reading comprension. However, we expected the computer to be used a lot while teaching writing. Regarding perceptions our hypotheses were that there were none differences between the pupils and the teachers while we expected differences between the upper secondary school and the elementary school.   The result of the investigation shows that the computer is used little in the education of Spanish as a foreign language regarding reading comprehension and written production. As far as the differences between the teachers and the pupils are concerned the study shows that their perceptions differed. The comparison between upper secondary school and elementary school indicates several differences in the use of computers. All the results refuted out hypotheses except the last one indicating the differences between the upper secondary and elementary school which was confirmed.

Esta dissertação investiga os efeitos do desenvolvimento da linguagem ‒ típico (DTL) e atípico (ADL) ‒ e da escolarização na forma como as crianças compreendem e produzem as orações adjectivas restritivas de SU e de OD (ao centro e à direita), de Ind e de Loc (Ind e Loc apenas testadas na tarefa de repetição). A amostra foi constituída por 3 grupos de crianças – dos quais16 têm DTL do Pré-escolar; 13 são do 2.º ano básico com DTL e 7 têm ADL ‒ e por 1 grupo de adultos (o grupo de controlo) com 10 indivíduos. Através da aplicação das tarefas de representação e de repetição de Vasconcelos (1991) e da narrativa ‘A história do gato’, de Hickmann (1982), os resultados mostram a maior acessibilidade das adjectivas SU e OD à direita; elucidam-nos também sobre a importância que o processo de desenvolvimento linguístico e a escolarização têm para a temática. /ABSTRACT: This dissertation research the effects of typical (DTL) and atypical language development (LI), and the formal education system itself on the manner in which children understand and produce restrictive relative clauses of subject (SU) and direct object (DO) (center and right embedded), indirect object (Ind) and locative (Loc); Ind and Loc atested merely on construction tasks. The complete sample includes 3 groups of children - 16 pre-school with DTL; 13 in 2nd grade with DTL and 7 children diagnosed with LI - and 1 group of adults (control group)10 individuals. The results of representation and repetition exercises by Vasconcelos (1991) and the narrative of Hickmann’s ‘Cat story’ (1982) revealed that the majority of the participating children master more easily SU and OD clauses relative clauses with right association; and also important role of the language development process and of School for the matter.

Esta tesis doctoral pretende aportar nuevos datos sobre los efectos del enfoque AICLE (Aprendizaje Integrado de Contenido y Lengua Extranjera) en las habilidades productivas y receptivas de los alumnos de una escuela privada de Barcelona (Catalunya). Se trata de una comunidad bilingüe en la que las lenguas oficiales son el catalán y el español y en la que el inglés representa la tercera lengua del curriculum. Con este objetivo, se analizan longitudinalmente 100 alumnos bilingües catalán / español de edades comprendidas entre 12 y 15 a lo largo de dos años académicos en dos contextos de exposición diferentes: EFL (inglés sólo como asignatura de lengua extranjera, n=50, grupo de control) y AICLE (inglés como medio de instrucción cuando estudian ciencias naturales, n=50, grupo experimental). Se extraen datos a partir de las habilidades productivas y receptivas y se analizan de forma cuantitativa y cualitativa utilizando un diseño posttest al final de cada curso académico. Los resultados demuestran la efectividad del enfoque AICLE aunque no de forma generalizada en todas las habilidades. A diferencia de investigaciones anteriores, es importante destacar la mejora de la corrección dentro de la producción escrita y de las habilidades léxico-gramaticales. Finalmente, los resultados tienden a confirmar que el factor edad es relevante y que obtienen mejores resultados los sujetos mayores.
The present study seeks to contribute new evidence on the effects of the CLIL approach (Content and Language Integrated Learning) on the learners’ productive and receptive skills in a private school in Barcelona (Catalonia). This is a bilingual community in which both Catalan and Spanish are official languages and where English represents the third language included in the currículum. For that purpose, 100 bilingual Catalan / Spanish students aged 12 to 15 are analysed longitudinally over two academic years in two different types of exposure contexts: EFL (English only as a foreign language school subject, n=50, control group) and CLIL (English as medium of instruction when learning Science, n=50, experimental group). Data are elicited both for productive and comprehension skills and are analysed quantitatively and qualitatively using a posttest design at the end of each academic year. The results show the effectiveness of the CLIL approach, however not in all skills. In contrast with findings published in previous studies, the subjects’ writing and particularly so accuracy, significatively progressed and so did lexico-grammatical abilities.Results also tend to confirm that age had an impact and thus the older, the better.

While previous research on language development has highlighted the facilitating role of gesture (mainly deictic gesture) in children’s early access to meaning, little is known about the possible facilitating role of prosody and also of co-speech gestures in children’s pragmatic development in the preschool years. Previous work on developmental pragmatics has focused on the acquisition of morphosyntactic and lexical forms, and there is a need to adopt a more integrative multimodal perspective. The overarching aim of this thesis is to experimentally investigate, through a set of cross-sectional studies with preschool children (3- to 5-year-olds), whether prosodic and gestural cues serve as pragmatic precursors in the development of two key pragmatic phenomena, namely knowledge state (i.e., commitment to the status of information) and politeness (e.g., broadly speaking, adjusting one’s language). The first study uses a forced-choice paradigm to investigate preschool children’s understanding of another speaker’s knowledge state, presented in audio only, video only and audio-visual formats. Results show that overall children perform significantly better in detecting a speaker’s uncertainty when they have gestural cues present, and, importantly, the younger children were significantly better in detecting a speaker’s uncertainty when listening to a speaker’s intonation contour as compared to uncertainty expressed through a lexical epistemic adverb. The second study analyzes children’s (and adults’) multimodal expression of their knowledge state through an object guessing game by evaluating their production of prosodic, gestural and lexical cues and additionally assessing their self-assessment of their knowledge state. Results show that while preschool children are not yet able to self-report on their knowledge state, in the younger group, children encode their knowledge state through prosodic and gestural means only. And only in the older age group do children start to use a few lexical markers to signal their uncertainty. The third study uses a forced-choice paradigm to assess children’s understanding of a speaker’s politeness presented in audio only, video only and audio-visual formats. Results show that 3-year-old children detect a speaker’s polite stance significantly more through facial cues and intonation, highlighting children’s early ability to extract meaning from intonation when lexical cues are kept the same. Finally, the fourth study explores children’s multimodal production of politeness in semi-spontaneous requests in different sociopragmatic situations. Results show that regardless of the age group, children marked politeness through fine-grained gestural and prosodic means when producing requests to an adult with high social distance as compared to a classmate with low social distance, and this also depends on the cost of the request. Altogether the results of these studies demonstrate that children’s early pragmatic comprehension and expressive abilities rely strongly on prosodic and gestural marking, developing well before children master lexical and morphosyntactic markers. More specifically, the four studies presented in this thesis bring forth evidence that both prosody and co-speech gestures play a precursor role in children’s pragmatic development of knowledge state and politeness. Ultimately, the thesis highlights the importance of approaching the study of children’s pragmatic development from a multimodal perspective.
Tot i que les investigacions prèvies sobre el desenvolupament del llenguatge han destacat el paper facilitador del gest (principalment, del gest díctic o d’assenyalament) en l'accés primerenc dels nens al significat del llenguatge, se sap poc sobre els beneficis de la prosòdia i dels gestos de la parla en el desenvolupament pragmàtic dels nens en els anys preescolars. La recerca que s’ha fet sobre el desenvolupament de la pragmàtica s'ha centrat en l'adquisició de formes morfosintàctiques i lèxiques, però és important adoptar una perspectiva multimodal més integradora. L'objectiu general d'aquesta tesi consisteix a investigar experimentalment, a través de quatre estudis transversals amb nens d’edat preescolar (de 3 a 5 anys d'edat), si els senyals prosòdics i gestuals actuen com a precursors pragmàtics en el desenvolupament de dos fenòmens pragmàtics, concretament el posicionament epistèmic (i.e., el grau de certesa del parlant sobre la informació expressada) i la cortesia. El primer estudi utilitza un paradigma d'elecció forçada per investigar la comprensió dels nens en edat preescolar sobre el posicionament epistèmic d'un altre parlant, presentat en tres condicions (només en àudio, només en vídeo i en format audiovisual). Els resultats mostren que els nens detecten millor la incertesa d'un parlant quan estan exposats a indicis gestuals. Crucialment, els nens de tres anys detecten millor la la incertesa d'un parlant quan la incertesa s'expressa a través de la prosòdia que quan s'expressa a través d’adverbis epistèmics. El segon estudi analitza l'expressió multimodal de l’estat epistèmic dels nens (i dels adults) a través d’un joc d’endevinar objectes. L'anàlisi dels senyals prosòdics, gestuals i lèxics mostren que, mentre els nens d’edat preescolar encara no poden valorar el seu posicionament epistèmic en canvi sí que codifiquen el seu grau de certesa a través de senyals prosòdics i gestuals. Només en el grup d'edat més gran els nens comencen a utilitzar alguns marcadors lèxics. El tercer estudi utilitza un paradigma d'elecció forçada per avaluar la comprensió dels nens sobre la cortesia d'un parlant, presentada també en tres condicions (només en àudio, només en vídeo i en format audiovisual). Els resultats mostren que els nens de 3 anys poden detectar una actitud educada a través de senyals facials i entonatius quan es mantenen constants les marques lèxiques. Els resultats mostren la capacitat inicial dels nens per extreure el significat de l'entonació, de forma paral·lela al que passa amb la gestualitat. Finalment, el quart estudi explora l'expressió multimodal de la cortesia en peticions emprades en diferents situacions sociopragmàtiques. Els resultats mostren que, independentment del grup d'edat, els nens marquen la cortesia a través de senyals gestuals i prosòdics detallats quan es fan peticions a un adult amb més distància social, en comparació amb un company amb qui presenten una distància social menor. L'ús d'aquestes marques també depèn del cost de la petició. En resum, els resultats dels quatre estudis de la tesi demostren que les habilitats primerenques de comprensió i d’expressió pragmàtica es basen en el marcatge prosòdic i gestual. i que aquestes es desenvolupen molt abans que els nens controlin els marcadors lèxics i morfosintàctics. Així, els quatre estudis presentats en aquesta tesi posen de manifest que tant la prosòdia com els gestos de la parla actuen com a precursors en el desenvolupament pragmàtic dels llenguatge. En definitiva, la tesi posa de relleu la importància d’aproximar-se a l'estudi del desenvolupament pragmàtic infantil des d'una perspectiva multimodal.
A pesar de que las investigaciones previas sobre el desarrollo del lenguaje hayan destacado el papel facilitador del gesto (principalmente, del gesto deíctico o de señalamiento) en el acceso temprano de los niños al significado del lenguaje, poco se sabe aún sobre los beneficios de la prosodia y de los gestos del habla en el desarrollo pragmático de los niños en etapa preescolar. Hasta ahora, las investigaciones sobre el desarrollo de la pragmática se han centrado en la adquisición de formas morfosintácticas y léxicas, haciéndose necesario adoptar una perspectiva multimodal más integradora. El objetivo general de esta tesis consiste en investigar experimentalmente —a través de cuatro estudios transversales con niños de edad preescolar (de 3 a 5 años de edad)— si las señales prosódicas y gestuales actúan como precursores en el desarrollo de dos fenómenos pragmáticos, concretamente del posicionamiento epistémico (i.e., del grado de certeza del hablante sobre la información expresada) y de la cortesía. El primer estudio utiliza un paradigma de elección forzada para investigar cómo los niños en edad preescolar comprenden el posicionamiento epistémico de otro hablante, presentado los estímulos en tres condiciones (solo en audio, solo en vídeo y en formato audiovisual). Los resultados muestran que los niños detectan mejor la incertidumbre de un hablante cuando están expuestos a indicios gestuales. Crucialmente, los resultados también muestran que los niños de tres años detectan mejor la incertidumbre de un hablante cuando esta viene expresada a través de la prosodia que cuando lo hace a través de adverbios epistémicos. El segundo estudio analiza la expresión multimodal del estado epistémico de los niños (y de los adultos) a través de un juego de adivinar objetos. El análisis de las señales prosódicas, gestuales y léxicas muestra que, aunque los niños en edad preescolar todavía no pueden valorar su posicionamiento epistémico, los del grupo de menor edad ya son capaces de codificar su grado de certeza a través de señales prosódicas y gestuales, mientras que solo los niños del grupo de mayor edad empiezan a utilizar algunos marcadores léxicos. El tercer estudio utiliza también un paradigma de elección forzada para evaluar la comprensión de los niños sobre la cortesía de un hablante, presentado también los estímulos en tres condiciones (solo en audio, solo en vídeo y en formato audiovisual). Los resultados muestran que los niños de 3 años son capaces de detectar una actitud cortés significativamente mejor a través de señales faciales y entonativas, destacando además la capacidad temprana de los niños para extraer el significado de la entonación cuando las marcas léxicas se mantienen constantes. Finalmente, el cuarto estudio investiga la expresión multimodal de la cortesía en peticiones realizadas en diferentes situaciones socio-pragmáticas. Los resultados muestran, por un lado, que, independientemente del grupo de edad, los niños marcan la cortesía a través de señales gestuales y prosódicas diferenciadas en función de si las peticiones van dirigidas hacia un adulto con el que mantienen una mayor distancia social, o bien hacia un compañero con quien la distancia social es menor. Además, los resultados también muestran que el uso de estas marcas también depende del coste de la petición. En resumen, los resultados de los cuatro estudios de esta tesis demuestran que las habilidades tempranas de la comprensión y expresión de significados pragmáticos se basan en el marcaje prosódico y gestual, y que, además, estas habilidades se desarrollan mucho antes de que los niños dominen los marcadores léxicos y morfosintácticos. De este modo, los cuatro estudios presentados en esta tesis ponen de manifiesto que tanto la prosodia como los gestos del habla actúan como precursores en el desarrollo pragmático del lenguaje, subrayando así la necesidad de aproximarse al estudio del desarrollo pragmático infantil desde una perspectiva multimodal.

Research on clear speech has shown that the type of clear speech produced can vary depending on the speaker, the listener and the medium. Although prior research has suggested that clear speech is more intelligible than conversational speech for normal-hearing listeners in noisy environments, it is not known which acoustic features of clear speech are the most responsible for enhanced intelligibility and comprehension. This thesis focused on investigating the acoustic characteristics that are produced in clear speech to foreigners and infants. Its aim was to assess the utility of these features in enhancing speech intelligibility and comprehension. The results of Experiment 1 showed that native speakers produced exaggerated vowel space in natural interactions with foreign-accented listeners compared to native-accented listeners. Results of Experiment 2 indicated that native speakers exaggerated vowel space and pitch to infants compared to clear read speech. Experiments 3 and 4 focused on speech perception and used transcription and clarity rating tasks. Experiment 3 contained speech directed at foreigners and showed that speech to foreign-accented speakers was rated clearer than speech to native-accented speakers. Experiment 4 contained speech directed at infants and showed that native speakers rated infant-directed speech as clearer than clear read speech. In the fifth and final experiment, naturally elicited clear speech towards foreign-accented interlocutors was used in speech comprehension tasks for native and non-native listeners with varying proficiency of English. It was revealed that speech with expanded vowel space improved listeners’ comprehension of speech in quiet and noise conditions. Results are discussed in terms of the Lindblom’s (1990) theory of Hyper and Hypoarticulation, an influential framework of speech production and perception.

This thesis investigated the relationship between sentence production and comprehension. A combination of behavioural and neuroimaging techniques were used to examine the extent to which sentence production and comprehension engage common or distinct mechanisms, with specific focus on the processes engaged by semantic/syntactic competition. Behavioural studies in Chapter 2 indicated that high-competition cases were more difficult to understand and produce than low-competition cases, and that difficulty varied as a function of the number of alternative associations entertained during performance in both tasks. In Chapter 3, an fMRI study indicated that production and comprehension shared a common competition mechanism within left inferior frontal gyrus (LIFG). However, they engage distinctive networks that interact with LIFG, with production eliciting a larger network including areas involved in sentence planning and memory retrieval. Further asymmetries across tasks were revealed in Chapter 4, in which behavioural results and neural networks were compared across adults and adolescents. This study also demonstrated the occurrence of shifts in the neural networks involved in competition resolution throughout development, thereby providing a strong link between poor behavioural performance and the underdevelopment of pre-frontal inhibitory mechanisms in adolescents. Chapter 5 used an improved experimental paradigm from that in Chapters 3 and 4. The results showed that production elicits more activity than comprehension in the dorsal language route thus confirming the engagement of task-specific control processes. Interestingly, this study also revealed a common area of LIFG involved in both tasks, but also differences within LIFG, suggesting the possibility of task-specific circuitry. Together, the findings suggest that production and comprehension share fronto-temporal areas that store and manage abstract linguistic associations between words and structures. However, they differ in the manner in which linguistic information is used, as is evident by the recruitment of distinct networks. Implications for models of language processing are discussed.

This study investigates linguistic, perceptual, and pedagogical change (LPPC) in a short-term, study abroad English immersion program. It proposes the LPPC Interactive Model of second language acquisition based on Gardner's 1985 socioeducational model and Woods' 1996 beliefs, attitudes, and knowledge (BAK) structure. The framework is applied in a cross-cultural context, highlighting participants in the 1993 Camosun Osaka Aoyama English Language Institute involving Japanese English-as-a-Second-Language (ESL) students from Aoyama Junior College in Osaka, Japan, and non-Japanese ESL teachers at Camosun College and Canada's University of Victoria in British Columbia. The study examined the definition of teacher achievement; distinctions between language activation and language acquisition in the short-term, study abroad context; development of the constructs student BAK+, teacher BAK+, and class BAK+ to describe interactions in "class fit"; and the influence of temporal parameters on linguistic, perceptual, and pedagogical change. Data from teacher and student surveys and interviews suggest that change occurs in each of the linguistic, perceptual, and pedagogical dimensions and support constructs proposed for the model.

Recent approaches to cognition have proposed that our understanding of the world and of language is rooted in our perceptual and motoric embodiment This thesis investigates a central idea of the embodied approach to cognition: that language comprehension prompts for the activation of perceptuomotor activity. This perceptuom'otor activity is thought to involve similar processes and brain areas to those in actual perceptioij and action. One problem for embodied approaches to cognition and language comprehension is how to account for abstract concepts and abstract language. Consequently, this thesis has two main goals. Firstly, it is to test and extend our existing knowledge of the role of perceptuomotor processing in language comprehension. A secondary aim is to investigate both theoretically and empirically whether the processing of abstract language involves perceptuomotor processing, given the idea that one important way in which we understand abstract language is through metaphoric projection from more concrete concepts. This thesis employs a variety of different psycholinguistic methodologies all using reaction time measures, in nine experiments. One set of studies investigate how language processing can interact with the execution of actions that are semantically related to words and sentences, and presents the Word Action Compatibility Effect A second set of experiments examines how irrelevant static and dynamic visuospatial information can affect the processing of words and sentences. A final chapter theoretically investigates claims of metaphoric structuring of the conceptual domain of quantity. The thesis represents a sustained investigation of key ideas in the embodied approach to language comprehension, develops new psycholinguistic methodologies and subjects a number of important theoretical ideas to empirical investigation.

This dissertation presents and evaluates the hypothesis that event structure information such as telicity is used during language comprehension. A verb or verb phrase is telic if it denotes an event that necessarily progresses towards an endpoint. The major experimental finding presented in this dissertation is that garden pathing is less severe in reduced relative clause sentences with telic embedded verbs than in those with atelic embedded verbs. For example, in the structurally ambiguous sentence 'The actress awakened/sketched by the writer left in a hurry', less comprehension difficulty occurs on the word 'by' when the embedded verb is telic ('awakened') than when it is atelic ('sketched'). On-line measures of comprehension difficulty in three different experimental paradigms showed this result at the earliest disambiguation point (on the by-phrase). Two of these paradigms involved comprehension in reading, and the third one involved spoken language comprehension. These experiments also included the factor of obligatory transitivity: whether or not the verb requires a direct object. The results show that telicity and obligatory transitivity both immediately affect the severity of the garden path independently of each other. In order to address the issue of how to categorize verb phrases as telic or atelic, I conducted a computerized study which collected semantic judgments and grammaticality judgments on verb phrases used in three classic telicity tests from the event structure literature. The participants in the study were 24 English-speaking students in an introductory linguistics course. The results provide preliminary evidence that sentence frames, such as the adverbials 'for an hour' and 'in an hour', provide an objective means of categorizing verb phrases as telic or atelic. The research strongly suggests that verb telicity information should be included in models of human language comprehension. I discuss means of including telicity in several pre-existing comprehension models. The account that best explains the telicity and transitivity effects taken together is based on identifying canonical sentence patterns associated with thematic roles, as proposed by Townsend and Bever (2001). The information that a verb is inherently telic activates the use of an NV(N) template with an obligatory theme role.

The purpose of this research was to examine from a syntactic and narrative structure perspective two narrative summary types: a summary with a length constraint and an unconstrained summary. In addition, this research served to develop a multidimensional theory of narrative comprehension. College freshmen read two short stories written by written by Sake and were asked to write a constrained summary for one text and an unconstrained summary for the other text. Following this the subjects completed a metacognitive questionnaire. The summaries were analyzed to examine transitivity features and narrative structure features. The metacognitive questionnaires were examined to extract information about plot structure, differences between one and two episode stories, and to gain insight into the strategies used by subjects in producing both summary types. A Paired t- test conducted on the data found that there was a significant transitivity feature mean difference between a constrained summary and an unconstrained summary indicating that the number of transitivity features produced from each summary type were task dependent. Chi-square tests conducted on the data found that there were proportional differences in usage between plot features and thematic abstract units in an unconstrained summary and a constrained summary indicating that plot features and thematic abstract units produced from each summary type were task dependent. Qualitative analyses indicated that setting, goal, and resolution are typical within plot organization, there are summary production differences between one and two episode narratives, and subjects do not seem to be aware of summary production strategies. The results of this research have implications for comprehension and writing instruction.

This study evaluated the comprehension of inference statements by language-learning disabled (LLD) children and children with normal language development (NL) under two conditions: uncontextualized and contextualized. The contextualized condition was designed to encourage retrieval of information from the subject's general knowledge — a procedure proposed to encourage elaborative inference-making. Two text passages were analyzed according to a model developed by Trabasso and presented by Trabasso, van den Broek & Suh (1989), which yielded a set of bridging causal connections across clause units. Sets of three true and three false causal inference statements were developed to represent bridging inferences for each story. In addition, three true and three premise statements were obtained directly from each story, yielding a total of twelve statements for each text. Subjects were ten language-learning disabled students (7 boys, 3 girls) and ten children with normal language development (5 boys, 5 girls) aged 9 to 11 years old. Mean age for children in both groups was 10 years, 4 months. Children were selected for the LLD group on the basis of the following criteria: (1) enrollment in a learning assistance or learning resource program for learning-disabled students, preferably for remediation of Language Arts; (2) history of speech-language intervention in preschool or early primary grades; (3) normal nonverbal cognitive skills; (4) lexical and syntactic comprehension within normal abilities (as determined by standardized language tests for the LLD group); (5) native English speaker and (6) normal hearing ability. Every subject received both stories and conditions. Story presentation and condition were counterbalanced across 8 of the 10 subjects in each group; condition only was counterbalanced across the remaining two subjects in each group. Inference and premise statements were randomized; each random set was randomly presented to each subject. Items were scored correct or incorrect. Subjects were also asked to answer open-ended wh-questions. Responses were compared and analyzed using a nonparametric statistical method appropriate for small sample sizes. Results indicated significant differences between the LLD and the NL groups on the number of correct responses to inference and premise items. Both groups scored significantly worse on inference than premise items. Analysis did not indicate that the LLD group scored significantly worse on inference items than the NL group did. Results also suggested that a contextualization effect operated for both groups, which affected the retention of premise items but acted to improve scores on inference items. This effect was seen most notably for the LLD group.

This dissertation research investigates the cognitive mechanisms underlying second language (L2) listening comprehension. I use three types of sentential contexts, congruent, neutral and incongruent, to look at how L2 learners construct meaning in spoken sentence comprehension. The three types of contexts differ in their context predictability. The last word in a congruent context is highly predictable (e.g., Children are more affected by the disease than adults), the last word in a neutral context is likely but not highly predictable (e.g., Children are more affected by the disease than nurses), and the last word in an incongruent context is impossible (e.g., Children are more affected by the disease than chairs). The study shows that, for both native speakers and L2 learners, a consistent context facilitates word recognition. In contrast, an inconsistent context inhibits native speakers’ word recognition but not that of L2 learners. I refer to this new discovery as the facilitation-without-inhibition phenomenon in L2 listening comprehension. Results from follow-up experiments show that this facilitation-without-inhibition phenomenon is a result of insufficient suppression by L2 learners.
