Résumé :
AbstractTime preference reversal refers to systematic inconsistencies between preferences and bids for intertemporal options. From the two eye-tracking studies (N1 = 60, N2 = 110), we examined the underlying mechanisms of time preference reversal. We replicated the reversal effect in which individuals facing a pair of intertemporal options choose the smaller-sooner option but assign a higher value to the larger-later one. Results revealed that the mean fixation duration and the proportion of gaze time on the outcome attribute varied across the choice and bid tasks. In addition, time preference reversals correlated with individual differences in maximizing tendencies. Findings support the contingent weighting hypothesis and strategy compatibility hypothesis and allow for improved theoretical understanding of the potential mechanisms and processes involved in time preference reversals.

Résumé :
Attention is essential to everyday life: without some selective function to guide and limit the processing of incoming information, our visual system would be overwhelmed. A description of the spatiotemporal dynamics of attention is critical to our understanding of this basic human cognitive function and is the primary goal of this dissertation. In particular, the research reported here is aimed at examining two aspects of the spatiotemporal dynamics of attention: a) the rate at which the focus of attention is shrunk and expanded along with the factors that influence this rate, and b) the factors governing whether attention is deployed as either a unitary or a divided focus. The present research examines the spatiotemporal dynamics of focal attention by monitoring the pattern of accuracy that occurs when participants attempt to identify two targets embedded in simultaneously presented streams of items. By asking participants to monitor these streams simultaneously, with the spatial and temporal positions of the two targets in the streams being varied incrementally, it is possible to index the extent of focal attention in both space and time. Chapter 2 develops this behavioural procedure and assesses the rate at which the focus of attention is contracted. A qualitative model is put forward and tested. Chapter 3 examines factors that modulate the temporal course of attentional narrowing in young adults who presumably can exercise efficient control of attentional processes. In contrast, Chapter 4 examines the effect of reduced attentional control by examining the same process in older adults. The second goal of this thesis was to examine whether focal attention is deployed as a unitary or a divided focus. These two perspectives are generally viewed as mutually exclusive. The alternative hypothesis pursued in Chapter 5 is that focal attention can be deployed as either a single, unitary focus or divided into multiple foci, depending on the observers mental set and on the task demands. The final chapter then combines and compares the findings across all experiments and evaluates how they fit in with current theories of visual attention.

Résumé :
O processamento visual se dá por duas vias, Dorsal (localização/movimento) mobilizada por TRS (tempo de reação simples), e Ventral (forma/cor) mobilizada por TER (tempo de reação escolha). Apresentamos uma nova abordagem para se investigar a distribuição dos recursos atencionais. Os métodos psicofísicos vigentes amostram repetidas vezes poucos pontos. Optou-se por amostrar muitos pontos na tela do computador poucas vezes, obtendo-se amostragem de uma grande área. Obteve-se um mapa de detalhamento da distribuição atencional. Experimentos de atenção voluntária: I. Tarefa de TRS, mobilizando a via Dorsal. Na situação de atenção difusa. II. TRE, mobilizando a via Ventral. Os estímulos possíveis diferiam na cor e foram respondidos ao se pressionar um botão, atenção difusa. III. TRE, focando-se a atenção em duas molduras, caracterizando atenção dividida. Os resultados demonstraram um favorecimento do hemicampo inferior para a TRS e um favorecimento do hemicampo superior para TER. Apareceram dois focos na atenção dividida fortalecendo a hipótese da divisão atencional.
Visual processing has two pathways: Dorsal (localization/movement) mobilized for Simple Reaction Time tasks (SRT); Ventral (shape/color) mobilized for Choice Reaction Time tasks (CRT). We presented an approach to investigate visual attentional resources. Usual psychophysical methods sample many times few points. We opted to sample many points few times aiming to enlarge the sampled visual field. It was obtained major details of the attentional distribution. Voluntary attention task: I. SRT, for Dorsal pathway. Stimuli were different in color answered triggering a button, in a diffusion attention paradigm. II. CRT, for Ventral pathway. Stimuli were two different color answered by triggering a button for each color in a diffuse paradigm. III. CRT, experimental subject instructed to focus attention in two frames for a splitted attention paradigm. Results showed anisotropy in the diffuse attention distribution, favouring the lower hemifield for SRT and superior hemifield for CRT. The splitted attention paradigm evidenced the presence of two attentional focuses.

Résumé :
Existe controvérsia na literatura sobre a possibilidade de divisão espacial da atenção visual. Alguns autores encontraram evidências de que a atenção visual voluntária se divide no espaço. No entanto, a possibilidade de divisão da atenção automática ainda não foi adequadamente investigada. O objetivo deste trabalho foi investigar a possibilidade de uma divisão da atenção visual automática no espaço. Em um primeiro e segundo experimentos testamos a possibilidade da atenção automática se dividir em um mesmo hemicampo (esquerdo ou direito). Em um terceiro e quarto experimentos investigamos a possibilidade de divisão da atenção automática entre os hemicampos visuais (esquerdo e direito). Em conjunto, os resultados deste trabalho sugerem que a atenção automática pode se dividir entre os hemicampos visuais esquerdo e direito, mas em cada um destes hemicampos forma um foco único longo e estreito.
Several studies demonstrated that voluntary visual attention can be divided. The possibility that this also occurs for automatic visual attention was investigated here. In the first and second experiments of this study the possibility of attention division in the same hemifield was examined. In the third and fouth experiments the possibility of attention division between hemifields was examined. The results suggest that automatic visual attention can not divide in the same hemifield but may divide between hemifields.

Résumé :
This thesis is concerned with the analysis of constrains of temporal coding in visual selective attention. It is well known that despite the great amount of visual information present in the environment the human visual system is only capable to attend and select some of it. How the brain is able to selectively prioritize relevant information and de-prioritize the irrelevant information in order to guide us through space, has been extensively investigated (Treisman and Gelade, 1980; Posner, 1980). Less is known about how this occurs over time. In the present thesis I investigate the role of temporal limitation of selective attention in brain damaged patients and in normal participants by using a simplified version (attentional dwell time paradigm, Duncan et al., 1994), of the Attentional Blink (AB) paradigm which involves the identification of two or more visual targets when stimuli are presented rapidly in temporal succession always at one location (Broadbent and Broadbent, 1987; Raymond, Shapiro and Arnell, 1992). Within this paradigm I have manipulated different factors which may influence this limitation such as: temporal binding, perceptual similarity among stimuli, task switching, integration of audio-visual information and working memory. In addition, by examining the AB in different brain lesioned groups, this thesis attempts to throws light on the neural mechanisms underlying temporal coding and selection. Evidence was provided of the influence of all these mechanisms in coding, selecting and consolidating visual information over time which suggest a multi components nature of temporal selection as well as possible involvements of a temporo-parietal network (Corbetta and Shulman, 2002) which governs their integration.

Résumé :
A atenção encontra-se incluída no grupo de funções psíquicas, agrupadas sob o nome de funções cognitivas que subsidiam o processo de aprendizagem escolar. Em relação à atenção visual, a literatura vem apontando a existência de diferenças no tempo de reação a estímulos visuais entre escolares com e sem distúrbios de aprendizagem (DA). Neste sentido, o objetivo deste estudo foi caracterizar a função atencional visual em escolares com DA. Participaram deste estudo 50 escolares, sendo 25 com o diagnóstico de distúrbio de aprendizagem, formando o grupo de estudo (GE), e 25 crianças sem queixas escolares, formando o grupo controle (GC), com faixa etária entre oito e 14 anos de idade. Os instrumentos utilizados foram o Teste de Atenção Visual (TAVIS4), um teste computadorizado composto por três tarefas para avaliar a capacidade atentiva de sustentar, selecionar e mudar o foco de atenção para estímulos visuais e da impulsividade motora, e a Escala de Conners na forma abreviada para professores, apropriado para discriminar crianças com problemas de comportamento e com sintomas de TDAH. Os resultados evidenciaram que o tempo de reação médio (TRM) do GC foi significativamente menor que o do GE na tarefa de atenção sustentada. O GE também apresentou diferença estatística significativa na atenção alternada, com menor número de acertos (NA), maior número de erros por omissão (EO) e maior número de erros por ação (EA). Na Escala de Conners a pontuação do GE foi maior do que do GC. Houve correlação entre os testes nas tarefas de atenção alternada e nas tarefas de atenção sustentada para o número de acertos (NA), erros por omissão (EO) e erros por ação (EA). Podemos inferir que as crianças com DA apresentam déficit dos processos atencionais, embora não possam ser caracterizadas com o TDAH. No subgrupo dos adolescentes houve diferença significativa na atenção seletiva para o número de erros por omissão (EO), no TRM da atenção sustentada e na atenção alternada para número de erros por omissão (EO) e erros por ação (EA). Houve correlação entre os testes, neste subgrupo do GE e GC na atenção seletiva para o número de acertos (NA), erros por omissão (EO) e erros por ação (EA). Portanto, os maiores índices apontados na escala (déficit atencional) estão associados aos piores resultados dos participantes nas tarefas de atenção alternada e sustentada. Pode-se observar que quanto maior a idade dos participantes, melhor é a capacidade de atenção seletiva, sustentada e alternada. Desta maneira, o TMR mais baixo do subgrupo dos adolescentes em comparação com o grupo geral pode evidenciar a melhora da atenção com o desenvolvimento. Porém, os adolescentes do GE apresentaram melhor desempenho do que as crianças, ou seja, algumas alterações notadamente persistem quando comparadas ao GC sugerindo uma disfunção dos mecanismos neuropsicológicos subjacentes ao processamento da atenção visual nos adolescentes com DA.
Attention is included in the group of psychic functions, grouped under the name of cognitive functions, and that support the learning process in school. Regarding the visual attention, literature has pointed to the existence of differences in reaction time to visual stimuli between students with and without learning disabilities (LD). In this sense, the purpose of this study was to characterize the visual attentional function in children with LD. A total of 50 students, including 25 with learning disorders without signs of Attention Deficit Disorder and Hyperactivity Disorder (ADHD), forming the study group (SG), and 25 children without impairments, forming the control group (CG) , aged between eight and 14 years old. The instruments used were the Test of Visual Attention (TAVIS4), computerized test consists of three tasks to assess the ability to sustain attentional, select and change the focus of attention to visual stimuli and motor impulsivity, and the Scale of the Conners abbreviated form for teachers, appropriate to discriminate children with behavior problems and ADHD signs. The results showed that the hit reaction time (HRT) of the CG was significantly less than the SG in the sustained attention task. SG also showed statistically significant differences in the alternating attention, with less number of right answers (RA), higher number of omission errors (OE) and higher number of commissions errors (CE). Scale of the Conners scores of GE was higher than the GC. There was a correlation between tests in alternating attention tasks and sustained attention tasks to the number of right answers (RA), omission errors (OE) and commission errors (CE). We may deduce that children with LD have deficits of attentional processes, although they cannot be characterized with ADHD. In the subgroup of adolescents was significant difference in selective attention to the number of omission errors (OE), the HRT of sustained attention and alternating attention to the number of omission errors (OE) and commission errors (CE). There was a correlation between tests, this subgroup of SG and CG in selective attention to the number of right answers (RA), omission errors (EO) and commissions errors (CE). So, the highest rates indicated on the scale (attentional deficits) are associated with worse outcomes of participants in the tasks of sustained and alternating attention. It can be observed that the higher the age of the participants, the better the ability of selective attention, sustained attention and alternating attention. That way, the HMT less subgroup of adolescents compared with the overall group may show an improvement in attention to development. However, adolescents SG improved their attentional capacity, but some changes persist especially when compared to CG suggesting a dysfunction of neuropsychological mechanisms underlying the processing of visual attention in adolescents with LD.

Résumé :
O presente trabalho analisou algumas das possíveis características do efeito da atenção intermodal entre elas: relação sinal/ruído e assincronia entre início dos estímulos (AIE) em relação ao tipo de tarefa realizada. Os Experimentos 1 e 2 mostraram que os efeitos da atenção intermodal se manifestam na presença de ruído visual externo, e que não se manifestam na ausência de ruído em uma AIE de 133 ms. No entanto, o Experimento 3 mostrou que quando a AIE é maior que a utilizada nos experimentos anteriores, o efeito intermodal se manifesta no comportamento na ausência de ruído visual externo. Finalmente, o Experimento 4 mostrou que em uma AIE curta (133 ms), e em uma tarefa de localização, o efeito intermodal se manifesta. Os resultados sugerem que o efeito atencional intermodal se manifesta na presença e na ausência de ruído visual e que o mecanismo de discriminação da frequência do alvo demora mais tempo para se completar do que o mecanismo de localização do alvo.
The current work examined the possible contribution of signal to noise ratio, the asynchrony between the onsets of the cue and the target (SOA) and the kind of task performed by the observer to the manifestation of crossmodal attentional effects. The Experiments 1 and 2 showed that crossmodal attentional effect appears when there is visual noise, but it does not appear when there is no visual noise at 133 ms SOA. The Experiment 3 showed that when the SOA is longer than 133 ms, the crossmodal attentional effect appears when there is no visual noise. The Experiment 4 showed that in a localization task, the crossmodal attentional effect appears even in a short SOA (133 ms). Taken together, the results indicate that crossmodal attentional effects appear when there is visual noise and when there is no visual noise. However, in the later condition and when the target has to be identified, the crossmodal attentional effect takes longer to appear.

Résumé :
How attention is controlled is one of the challenging topics in cognitive neuroscience and psychology. For spatially represented targets in the visual field it has been shown that some features of visual stimuli like different colors instantaneously ‘pop-out’, while others require a serial search which is conceived of as an effortful task. It is an open question whether dynamic feature of a stimulus are processed instantaneously without high attentional demand or serially with high demand. This question was studied in experiments on rhythm perception with periodically moving stimuli, and a visual search paradigm was employed. The search display consisted of vertically moving dots with regular rhythms; one dot however moved with a different period, and this dot with a longer or shorter period had to be detected as fast as possible. To make the period of the movement a critical target, amplitudes and phases of the distractors were randomized. It was observed that the perception of a visual rhythm defined only by the period does not lead to a pop-out effect. Apparently, the conjunction of period, equal phase and equal amplitude of movements are necessary for an effortless processing of visual rhythms. Interestingly, a faster rhythm compared to the distractors was detected with shorter reaction times. In additional experiments, it was for instance shown that auditory information supports the extraction of rhythmic visual targets indicating an intermodal mechanism. In another experimental set-up it was tested whether the attentional machinery is controlled by a common temporal mechanism. Experiments on ‘inhibition of return’ (IOR) have indicated that attentional control in the peri-foveal region of the visual field underlies a different neuronal mechanism compared to the periphery of the visual field. This eccentricity effect of IOR raises the question, whether attentional control for the visual periphery is characterized by a longer time constant as the peripheral inhibitory control is much stronger. Experimental evidence indicates, however, that the two attentional systems share the same time window of approximately three seconds. These observations support the notion of a functional subdivision of the visual field which is overcome, however, by a common temporal control mechanism.
Wie Aufmerksamkeit kontrolliert wird, ist eine der besonderen Herausforderungen in den kognitiven Neurowissenschaften und der Psychologie. Für räumlich repräsentierte Reize konnte gezeigt werden, dass bestimmte Aspekte visueller Reize wie verschiedene Farben sofort hervorstechen („pop-out“), während für andere Reize serielle Such-Strategien notwendig sind, die also mentalen Aufwand erfordern. Es ist eine offene Frage, ob dynamische Merkmale von Reizen ohne besonderen Aufwand verarbeitet werden, oder ob serielle Prozesse erforderlich sind, um sie zu erkennen. Diese Frage wurde in Experimenten über Rhythmus-Wahrnehmung mit periodisch sich bewegenden Reizen untersucht, und ein visuelles Such-Paradigma wurde angewandt. Es wurden auf einem Display vertikal sich bewegende Punkte gezeigt, wobei einer der Punkte sich mit einer anderen Periode, schneller oder langsamer, bewegte, und diese Punkte mussten so schnell wie möglich erkannt werden. Um nur die Periode als kritische Variable zu untersuchen, wurde die Phase und die Amplitude der anderen Reizpunkte randomisiert. Es wurde festgestellt, dass die unterschiedliche Periode allein nicht zu einem „pop-out“-Effekt führt. Damit ein abweichender, sich bewegender dynamischer Reiz erkannt wird, müssen offenbar Periode, Phase und Amplitude übereinstimmen. Reize mit einer kürzeren Periode als die Hintergrundreize wurden deutlich schneller erkannt. In weiteren Experimenten konnte beispielsweise gezeigt werden, dass akustische Information die Extraktion rhythmisch sich bewegender visueller Reize deutlich verbessert, was auf intermodale Effekte hinweist. In einer weiteren Studie wurde untersucht, ob die neuronale Aufmerksamkeits-Maschinerie gemeinsamen zeitlichen Prinzipien gehorcht. Versuche zum Phänomen des „Inhibition of Return“ (IOR, Hemmung der Aufmerksamkeits-Wiederkehr) haben ergeben, dass die Mechanismen der Aufmerksamkeits-Steuerung im perifovealen Bereich anderen Gesetzen gehorchen als in der Peripherie des Gesichtsfeldes. Dieser „Ekzentrizitäts-Effekt“ wirft die Frage auf, ob die zeitlichen Prozesse der Aufmerksamkeits-Kontrolle in der Peripherie durch längere Zeitkonstanten gekennzeichnet sind, da die inhibitorische Kontrolle dort ausgeprägter ist. Es zeigt sich allerdings, dass die beiden Aufmerksamkeits-Systeme das gleiche Zeitfenster von etwa drei Sekunden nutzen. Diese Beobachtungen stützen das Konzept der funktionellen Inhomogenität des Gesichtsfeldes, die aber durch einen gemeinsamen zeitlichen Mechanismus in eine kognitive Einheit gebracht wird.

Résumé :
Visual attention can be seen as a computational resource that aids perception in any part of the visual field to which it is applied. This resource is limited, however, as it cannot be applied everywhere at the same time, but constitutes an attentional "focus". It has been known since the groundbreaking work of Helmholtz (1896) that attention has mobility and can be willfully deployed in the periphery of the visual field. In the absence of such "effort of will" it tends to return to the region in or near the center of the visual field.

Résumé :
We used eye tracking to measure visual attention to tobacco products and pro- and anti-tobacco advertisements (pro-ads and anti-ads) during a shopping task in a three-dimensional virtual convenience store. We used eye-tracking hardware to track the percentage of fixations (number of times the eye was essentially stationary; F) and dwell time (time spent looking at an object; DT) for several categories of objects and ads for 30 adult current cigarette smokers. We used Wald F-tests to compare fixations and dwell time across categories, adjusting comparisons of ads by the number of each type of ad. Overall, unadjusted for the number of each object, participants focused significantly greater attention on snacks and drinks and tobacco products than ads (all P<0.005). Adjusting for the number of each type of ad viewed, participants devoted significantly greater visual attention to pro-ads than anti-ads or ads unrelated to tobacco (P<0.001). Visual attention for anti-ads was significantly greater when the ads were placed on the store’s external walls or hung from the ceiling than when placed on the gas pump or floor (P<0.005). In a cluttered convenience store environment, anti-ads at the point of sale have to compete with many other stimuli. Restrictions on tobacco product displays and advertisements at the point of sale could reduce the stimuli that attract smokers’ attention away from anti-ads.

Résumé :
Recent advances in visual sensing technology have gained much attention in the field of bridge inspection and management. Coupled with advanced robotic systems, state-of-the-art visual sensors can be used to obtain accurate documentation of bridges without the need for any special equipment or traffic closure. The captured visual sensor data can be post-processed to gather meaningful information for the bridge structures and hence to support bridge inspection and management. However, state-of-the-practice data postprocessing approaches require substantial manual operations, which can be time-consuming and expensive. The main objective of this study is to develop methods and algorithms to automate the post-processing of the visual sensor data towards the extraction of three main categories of information: 1) object information such as object identity, shapes, and spatial relationships - a novel heuristic-based method is proposed to automate the detection and recognition of main structural elements of steel girder bridges in both terrestrial and unmanned aerial vehicle (UAV)-based laser scanning data. Domain knowledge on the geometric and topological constraints of the structural elements is modeled and utilized as heuristics to guide the search as well as to reject erroneous detection results. 2) structural damage information, such as damage locations and quantities - to support the assessment of damage associated with small deformations, an advanced crack assessment method is proposed to enable automated detection and quantification of concrete cracks in critical structural elements based on UAV-based visual sensor data. In terms of damage associated with large deformations, based on the surface normal-based method proposed in Guldur et al. (2014), a new algorithm is developed to enhance the robustness of damage assessment for structural elements with curved surfaces. 3) three-dimensional volumetric models - the object information extracted from the laser scanning data is exploited to create a complete geometric representation for each structural element. In addition, mesh generation algorithms are developed to automatically convert the geometric representations into conformal all-hexahedron finite element meshes, which can be finally assembled to create a finite element model of the entire bridge. To validate the effectiveness of the developed methods and algorithms, several field data collections have been conducted to collect both the visual sensor data and the physical measurements from experimental specimens and in-service bridges. The data were collected using both terrestrial laser scanners combined with images, and laser scanners and cameras mounted to unmanned aerial vehicles.
