Abstract:
In Experiment 1, rats were trained on a discrimination between rubber- and sandpaper-covered arms of a maze after one group had been pre-exposed to these intra-maze cues. Pre-exposure facilitated subsequent discrimination learning, unless the discrimination was made easier by adding further discriminative stimuli, when it now significantly retarded learning. In Experiment 2, rats were trained on an extra-maze spatial discrimination, again after one group, but not another, had been pre-exposed to the extra-maze landmarks. Here too, pre-exposure facilitated subsequent discrimination learning, unless the discrimination was made substantially easier by arranging that the two arms between which rats had to choose were always separated by 135°. The results of both experiments can be explained by supposing that perceptual learning depends on the presence of features common to S+ and S-.

Abstract:
AbstractIt is commonly assumed that Aristotle defines a sense by reference to its ability to perceive the items that are proper to that sense, and that he explains perceptions of unities of these items, and discriminations between them, by reference to what is called the ‘common sense’. This paper argues in contrast that Aristotle defines a sense by reference, not only to its ability to perceive the proper items, but also to its ability to discriminate between them, and thus aims to show that Aristotle’s theory of sense perception is basically a theory of perceptual discrimination.

Abstract:
Perception and action interact in nearly every moment of daily life. Previous studies have demonstrated not only that perceptual input shapes action but also that various factors associated with action—including individual abilities and biomechanical costs—influence perceptual decisions. However, it is unknown how action fluency affects the sensitivity of early-stage visual perception, such as orientation. To address this question, we used a dual-task paradigm: Participants prepared an action (e.g., grasping), while concurrently performing an orientation-change-detection task. We demonstrated that as actions became more fluent (e.g., as grasping errors decreased), perceptual-discrimination performance also improved. Importantly, we found that grasping training prior to discrimination enhanced subsequent perceptual sensitivity, supporting the notion of a reciprocal relation between perception and action.

Full text
Abstract:
During the early stages of infant development the capacity for perceptual (i.e., visual) discrimination is shaped by infants' perceptual experience. Perceptual narrowing is one process hypothesized to account for developmental change. Perceptual narrowing research often demonstrates that infants before 6 months of age are able to discriminate a wide variety of events whereas infants beyond 6 months of age seemingly "lose" some perceptual abilities. Two investigations are proposed to examine the claim that younger, but not older infants can discriminate faces across species. The purpose of Experiment 1 was to determine whether an increase in familiarization and trial times would result in cross-species facial (i.e. faces of macaques) discrimination in 12-month-olds. The hypothesis was supported, adding evidence that perceptual discrimination becomes more constricted, or less efficient with age, but does not decline. Experiment 2 examined whether reducing both the time of familiarization and comparison time by 50% would allow infants sufficient time to discriminate. Results were consistent with the hypothesis and previous studies were corroborated. These findings highlight the important role of perceptual experience in young infants' perceptual discrimination abilities and provide a greater degree of clarity regarding present use of the concept perceptual narrowing.

Abstract:
Discrimination between similar stimuli is enhanced more by intermixed pre-exposure than by blocked pre-exposure to those stimuli. The salience modulation account of this intermixed-blocked effect proposes that the unique elements of intermixed stimuli are more salient than those of blocked stimuli. The inhibition account proposes that inhibitory links between the unique elements of intermixed stimuli enhance discrimination. The current thesis evaluated the two accounts in their ability to explain this effect in humans. In Experiments 1 and 2, categorisation and same-different judgements were more accurate for intermixed than for blocked stimuli. This indicates that intermixed pre-exposure decreases generalisation and increases discriminability more than does blocked pre-exposure. In Experiments 3 ?? 5, same-different judgements were more accurate when at least one of the two stimuli was intermixed. This enhanced discrimination was not confined to two stimuli that had been directly intermixed. These results are better explained by salience modulation than by inhibition. Experiments 6 ?? 8 employed dot probe tasks, in which a grid stimulus was followed immediately by a probe. Neither intermixed nor blocked stimuli showed facilitated reaction times when the probe appeared in the location of the unique element. In Experiments 9 ?? 11 participants learned to categorise the intermixed unique elements more successfully than the blocked unique elements, but only when the unique elements were presented on a novel background during categorisation. Experiments 6 ?? 11 provide weak evidence that the intermixed unique elements are more salient than their blocked counterparts. In Experiment 12, participants were presented with the shape and location of a given unique element, and were required to select the correct colour. Performance was more accurate for intermixed than for blocked unique elements. In Experiment 13, participants learned to categorise intermixed, blocked and novel unique elements. Performance was better for intermixed than for blocked and novel unique elements, which did not differ. None of the proposed mechanisms for salience modulation anticipate these results. The intermixed-blocked effect in human perceptual learning is better explained by salience modulation than by inhibition. However, the salience modulation accounts that have been proposed received little support. An alternative account of salience modulation is considered.

Abstract:
The increasing use of auditory graphs and sonifications in technology is leading to a wider variety of system users, which, in turn, suggests a need for research in how differences between individual listeners affect sound interpretation. As a first step in this arena, the current study investigates the question of whether or not cognitive abilities and musical experience predict frequency and tempo discrimination in individuals. Participants in the study were 30 undergraduate students from Georgia Institute of Technology and 20 adults from the Atlanta, Georgia community. In the cognitive ability session, participants completed the Operation Span (Ospan) task as a measure of working memory capacity and the Ravens Progressive Matrices task as a measure of spatial reasoning. In the auditory discrimination session, participants performed a tempo and a frequency discrimination task. Demographics on age, gender, handedness, years of playing a musical instrument, and years of formal musical training were also collected. A correlational analysis of all variables was performed. Paired-samples t-tests on the Weber fractions of the six threshold means were also performed to determine if there were any significant differences between the frequency thresholds and the tempo thresholds. Lastly, multiple hierarchical regressions were performed on each of the six dependent variables to identify significant predictors of frequency and tempo discrimination. The paired samples t-tests show a significant difference between 250 Hz and 840 Hz and between 250 Hz and 1600 Hz, a violation of Webers Law. However, this violation of Webers Law may be explained by the small sample size used in the study. The t-tests also show a significant difference between the means of 150 ms and 250 ms and between the means of 250 ms and 350 ms. The results of the regression analyses show that good performance on Ravens seems to predict lower thresholds at 1600 Hz. The results also show that good scores on Ospan appear to predict lower thresholds at 350 ms ICI. In addition to these significant predictors from the regression analyses, there are many significant correlations that provide further support that cognitive abilities are related to frequency and tempo discrimination.

Abstract:
Discrimination thresholds were obtained during a delayed spatial frequency discrimination task. In Experiment 1, we found that presentation of a mask 3 s before onset of a reference Gabor patch caused selective interference in a subsequent discrimination task. However, a 10 s interval abolished this masking effect. In Experiment 2, the mask was associated with a second spatial frequency discrimination task so that a representation of the mask had to be coded into short-term perceptual memory. The presence of this second discrimination task now caused similar interference effects on the primary discrimination task at both the 3 s and 10 s ISI conditions. The different results from these two experiments are best explained by a two-step perceptual memory mechanism. The results also provide further insight into the conditions under which stimulus representations are shared between the perceptual and memory domains.

Abstract:
We make frequent evaluations of subtle contrast differences in our visual environment, and often under challenging illumination conditions, whether photopic, scotopic or mesopic. Our contrast discrimination abilities are rigorously honed from an early age, and we continue to carry out these fine perceptual judgments throughout our lifetimes. Thus, the issue of whether substantial improvement in contrast discrimination is possible during later periods in life, such as during adulthood- and the circumstances that allow this- has sometimes come under discussion. Our adult macaque subjects underwent extensive training on a contrast discrimination task, in which stimuli were positioned at a variety of peripheral and parafoveal locations. We present clear evidence of contrast perceptual learning at the behavioural level and show that these changes have neuronal correlates primarily in V4, rather than in V1. Learning was specific to stimulus location and spatial frequency, but was transferable across orientations; it took place to a limited degree under stimulus roving conditions, and could be either facilitated or impeded by the addition of flanker stimuli, depending on the subject. Upon removal of flankers, levels of psychometric and neurometric performance returned to their pre-flanker state. In V4, learning-induced changes encompassed a shift in the point of neurometric equality and the semi-saturation constant (C50) towards the trained contrast; a decrease in noise correlations across channels; and an increase in choice probability. In V1, enhancements in performance were characterised by an increase in spike discriminability; a shift in the point of neurometric equality and the C50 towards the trained contrast(s); and a widening in the range and a steepening of the contrast response function, during the early phase of training. Deteriorations in performance were accompanied by the reverse effects on V1 activity; furthermore, a general decrease in V1 firing rates occurred when training was carried out over an extended period of time, after performance had reached its peak.

Abstract:
Current military operational environments are highly improvised and constantly evolving, threatening the lives of U.S. warfighters. For instance, since 2001, 60% of all hostile casualties and 65% of hostile injuries in the Middle East theater have been attributed to improvised explosive devices (IEDs). IEDs are powerful physical weapons, and the stressful atmosphere they, and other operational challenges create, can also result in a range of psychological dysfunctions, including anxiety, depression, alcohol abuse, and Post-Traumatic Stress Disorder (PTSD). Not only are these issues concerning for mental health reasons, they are also problematic in terms of combat performance. Extreme arousal (i.e., stress) negatively affects performance through the suppression of cognitive and physiological resources, which inhibits verbal, perceptual, and motor performance. Perceptual abilities are particularly susceptible to the effects of acute hyperarousal, and the degradation of these abilities may limit warfighters’ threat detection skills. Therefore, military researchers are interested in whether and how the visual perceptual field is changed under stress, and the Services are making predeployment training programs a priority, in an attempt to mitigate these concerns. This dissertation first outlines the cognitive processes related to visual perceptual abilities and how these processes are negatively affected by acute arousal. Current training programs in perceptual skills and stress tolerance are then described, along with recommendations for areas of improvement within the status quo. Based on these recommendations, an experimental procedure and five hypotheses were designed to assess training effects on visual perceptual skills and performance under stress. Experimental outcomes suggest that participants who were trained using a novel integrated perceptual skills plus stress resilience (“perceptual resilience”) program performed faster and with higher accuracy during a stressful threat detection task than participants trained using a perceptual skills-only program and participants trained using an existing status-quo knowledge trainer. Participants in this perceptual resilience training group also reported lower feelings of acute stress and anxiety immediately post-task than the two other training groups who did not receive the stress resilience training component. Based on these outcomes, implications for future military-specific training development, study limitations, and recommendations for future research is presented.

Abstract:
Colour mixing is fundamental to learning to paint. Students in visual art classes in secondary schools face problems in manipulating paint and discriminating colour. The kinds of base paints to be presented to students could be an important factor in learning about colour relationships and pigments. The purpose of this study was to determine whether Year 7 students generating colour mixes with paint using a triad of magenta, cyan and yellow were able to mix and discriminate more colours than if they used a triad of red(scarlet red), blue (ultramarine light) and yellow (lemon yellow) which is a base triad commonly used in schools. The Weddell Colour Discrimination Test was developed for use in this study which was a test that involved colour mixing with paint. The study used quasi-experimental designs for both a pilot study and a main study. Results indicated a significant difference in the ability to mix paint advantage of groups that used cyan , magenta and yellow. Implications for the use of particular colour triads in art classrooms and methods of teaching colour theory have emerged from this study. The Weddell Colour Discrimination test instrument developed in this study could be useful as both a diagnostic tool and a teaching tool as well as a data gathering method for further research.

Abstract:
Perception is constitutively a matter of discriminating and singling out particulars by employing perceptual capacities. To be a perceiver is to possess such capacities, to perceive is to employ them, and employing them constitutes perceptual states. What are perceptual capacities? Drawing on work in cognitive psychology, neuroscience, and developmental psychology, Chapter 2 develops an account of perceptual capacities. It includes an analysis of their function, their individuation and possession conditions, their physical and informational base, as well as their repeatability, fallibility, and the asymmetry of their employment in perception, on the one hand, and hallucination and illusion, on the other. In providing this analysis, the chapter gives an account of the general elements of perception.

Abstract:
The term ‘mind’ (mano) is used in a confused range of different and contradictory senses in the early Pāli canon. Buddhaghosa will impose order by distinguishing distinct cognitive modules, each with its proper domain of cognitive work. Early perception, the subliminal orienting, and initial reception of a stimulus into the perceptual process, is the function of ‘mind-element’ (mano-dhātu), a low-level cognitive system. Late perception and working memory is the function of a high-level cognitive system, ‘mind-discrimination-element’ (mano-viññāṇa-dhātu). In deference to ancient Buddhist tradition, Buddhaghosa refers to six sense-modalities, the sixth being called ‘mind’ (mano). Just as each of the five types of sensory datum enters perceptual processing though a proprietary sense-door, so the objects of mind enter through a ‘mind-door’. However, this is not a sixth channel, a window onto a proprietary sort of mental object, but is nothing other than the door gating projection into short-term working memory.

Abstract:
This study investigates the relationship between the production and perception of word-initial gemination in stops and fricatives in Tashlhiyt Berber. Gemination in this language is primarily implemented through longer duration, even for utterance-initial voiceless stops. This timing information is sufficient for native listeners to identify geminate fricatives and voiced stops and distinguish them from their singleton counterparts. For voiceless stops, however, native listeners’ discrimination performance is only slightly above chance level. Native speakers can thus encode a phonemic contrast at the articulatory level and yet be unable to fully decode it at the perceptual level. Implications of these results for the general issue of phonological representation of gemination are briefly discussed.

Abstract:
Covert spatial attention prioritizes the processing of stimuli at a given peripheral location, away from the direction of gaze, and selectively enhances visual discrimination, speed of processing, contrast sensitivity, and spatial resolution at the attended location. While correlates of this type of attention, which are believed to underlie perceptual benefits, have been found in a variety of visual cortical areas, more recent observations suggest that these effects may originate from frontal and parietal areas. Evidence for a causal role in attention is especially robust for the Frontal Eye Field, an oculomotor area within the prefrontal cortex. FEF firing rates have been shown to reflect the location of voluntarily deployed covert attention in a variety of tasks, and these changes in firing rate precede those observed in extrastriate cortex. In addition, manipulation of FEF activity—whether via electrical microstimulation, pharmacologically, or operant conditioning—can produce attention-like effects on behaviour and can modulate neural signals within posterior visual areas. We review this evidence and discuss the role of the FEF in visual spatial attention.

Full text
Abstract:
One dimension of the controversy over whether evaluative properties are presented in perceptual content has general roots in the debate over whether perceptual content, in general, is rich or austere. This chapter argues that we need to recognize a level of rich non-sensory perceptual content, drawing on experiences of chicken sexing and speech perception, to capture what our experience is like and our epistemic entitlements. In both cases (and many others), we are not conscious of the precise perceptual cues that are the basis for discriminations and, thus, the characterization of the phenomenal content of such experiences must go beyond sensory properties. Nevertheless, this point is arguably insufficient to establish the perception of evaluative properties. Their representation requires the subject to respond in certain ways. The chapter discusses how this should go for the case of pain and then, in outline, for moral properties.

Full text
Abstract:
This chapter argues that seeing is not only believing but also knowing. An ability to see things involves having one’s attention visually drawn to the object, or discriminating it from its surroundings in some way, or responding to it attentively, perhaps tracking it with your gaze if it is moving. The chapter considers ‘relational’ or ‘objectual’ seeing and its significance for all thinking about objects, while also emphasizing that thinking something about the objects you see requires considerably more than just seeing them. It suggests that any satisfactory understanding of human perceptual knowledge must make room for the fact that we know things about the world around us by perception alone. Since we can and do know many things about the world around us by perception alone, all such restrictive views of perceptual knowledge must be rejected.

Abstract:
Discrimination of speech and song through auditory signal is an exciting topic of research. Preceding efforts were mainly discrimination of speech and non-speech but moderately fewer efforts were carried out to discriminate speech and song. Discrimination of speech and song is one of the noteworthy fragments of automatic sorting of audio signal because this is considered to be the fundamental step of hierarchical approach towards genre identification, audio archive generation. The previous efforts which were carried out to discriminate speech and song, have involved frequency domain and perceptual domain aural features. This work aims to propose an acoustic feature which is small dimensional as well as easy to compute. It is observed that energy level of speech signal and song signal differs largely due to absence of instrumental part as a background in case of speech signal. Short Time Energy (STE) is the best acoustic feature which can echo this scenario. For precise study of energy variation co-occurrence matrix of STE is generated and statistical features are extracted from it. For classification resolution, some well-known supervised classifiers have been engaged in this effort. Performance of proposed feature set has been compared with other efforts to mark the supremacy of the feature set.
