Full textThroughout the historical trajectory of the Instituto Nacional de Educação de Surdos (INES), a pioneer institution in the education of the deaf in Brazil, it was possible to observe the existence of three approaches in the education of the deaf: oralism, total communication and bilingualism, which characterized and directed the pedagogical practices of the institution. Bilingualism, which is the most current approach, conceives the Língua Brasileira de Sinais (Libras) as the first language of the deaf and the Portuguese Language as the second language, to be learned in the written mode. However, the education of the deaf in the bilingual perspective also considers that the process of understanding the world by the deaf occurs through visuality (Perlin, 2013, SKLIAR, 2013, QUADROS, 2005). The fact that Libras characterizes itself as a space-visual language does not mean that all experiences provided to the deaf in the educational context should be restricted to the visual perception of this individual. According to Merleau-Ponty (1999), the body in movement is the main way of apprehension of the world by the human being. From this perspective, we understand that one of the areas that can contribute to the understanding and development of the visual language for the deaf is Art. Art, described as an area of knowledge that promotes the construction of knowledge through different languages, such as: theater, dance, visual arts and music, involves a process of the perception of what is in front of oneself, a self-perception and the perception of one´s environment, which transcends the use of the five senses of the human being (MERLEAU-PONTY, 1999). Having this in mind, the objective of this study was to investigate and discuss the proposal of training in Art offered to deaf students from the 6th to the 9th grade of elementary education, in bilingual public schools for the deaf in the city of São Paulo. The research in question has a qualitative approach and, in addition to the bibliographic review, has carried out an empirical research. The instrument used for data collection was the semi-structured interview and the individuals that participated in the research were Art teachers and coordinators of Elementary School II of the referred schools. The analysis of the data allowed the understanding that the interviewees recognize the importance of the area in the formation of the deaf, but demonstrate the development of an isolated work, emphasizing the need for a more integrated practice with the school team, as well as trainings that articulate the specific issues of the education of the deaf with the teaching of Art. Nevertheless, it was also possible to note the emphasis on the use of visual resources in Art classes, which was attributed to the ease of the deaf in relation to the visual language. The discussions made it possible to highlight the place of Art as a field of knowledge, as well as the importance of the body as the first way of apprehension of the world by the deaf, therefore, participant in the process of the construction of new knowledge.

Resumo: Neste trabalho procuramos demonstrar a existência de uma base fisiológica para a divisão triádica da semiótica estabelecida por Charles Sanders Peirce e que, o reconhecimento dessas bases pode apontar para o estabelecimento de uma teoria semiótica da criatividade. Assim, esta dissertação propõe que a estrutura triádica da semiótica deriva da própria estrutura evolutiva do cérebro humano. Utilizando-se a abordagem primeiramente proposta por Paul MacLean, de que o cérebro humano é produto de um processo evolutivo através do qual são mantidas e aperfeiçoadas suas estruturas básicas fundamentais, o que nos permite dividi-lo em arquiocórtex, paliocórtex e neocórtex, procuramos demonstrar a existência de uma relação direta entre tais estruturas e as categorias universais estabelecidas por Peirce. Sendo assim, são analisadas as possíveis relações entre a Primeiridade, a Secundidade e a Terceiridade com, respectivamente, o que foi denominado por MacLean de cérebro ¿reptiliano¿, cérebro ¿límbico¿ e cérebro ¿mamífero superior¿. Tais relações demonstram que a estrutura triádica encontrada por Peirce, baseado em suas categorias universais, não poderia ser diferente, pois é inerente a um aparato cognitivo de estrutura também triádica: o cérebro humano. Depois de explicitada, a base fisiológica da estrutura triádica da semiótica, tomamo-la como paradigma para a elaboração de nova abordagem para os processos criativos, assumindo que os mesmos decorrem da maior ou menor sensibilidade do indivíduo por uma ou outra categoria de percepção da realidade subjetiva ou objetiva ou mesmo pelo conjunto delas. Para demonstrar tal abordagem, analisamos a obra de alguns artistas a partir desse ponto de vista, estabelecendo assim, subsídios para uma teoria semiótica da criatividade
Abstract: This work aim to demonstrate that there is a physiologic base for the triadic division of Peircean semiotic and, if we accept this, we can point to the establishment of new semiotic theory for the creativity. This paper come to prop that the semiotic¿s triadic frame derives from the own human brain¿s evolutionary structure. Using the approach propose first of all by Paul McLean were the human brain is a product of an evolutionary process that keeps and increase it own fundamentals structure ¿ which permits its approach as arquiocortex, paliocortex and neocortex ¿ we try to demonstrate that its possible a straight relationship between such structures and the Peirce¿s universal categories. Thus the work brings out the possible relationship of Firstness, Secondness and Thirdness with respectively, what was named by MacLean as reptilian-brain, limbic-brain and high-mammalian-brain. Such relationship shows us that triadic frame founded by Peirce couldn¿t be different since it is inherent to a cognitive apparatus, which also owns an inner ternary structure: the human-brain. Finally, we use the physiologics bases of the semiotic¿s triadic frame as a paradigm for a new approach for the creative process, proposing they arose from the minor or mayor sensibility the individual has about one or another categories of reality¿s perception ¿ that can be objective, subjective or both. For this demonstration we analyze the work of few artists from this point of view, offering thus dates for a semiotic theory of creativity

Full textO Fenômeno Muitas Faces ocorre quando faces são apresentadas na periferia do campo visual. Caracteriza-se pela percepção de variações na imagem, tais como movimentos, mudanças de expressão facial, surgimento de outras características ou outras faces sobrepondo a face apresentada na foto-estímulo. Participaram do presente estudo, 60 voluntários (30 masculinos e 30 femininos), adultos (18 à 30 anos) e saudáveis. Todos foram testados com método psicofísico. Foram instruídos a observar, monocularmente, imagens acromáticas de face e de cadeira, centradas no ponto cego direito ou esquerdo, durante 3 minutos em cada uma das 4 situações experimentais. Foi solicitado aos voluntários que pressionassem a tecla 1 cada vez que percebessem movimento ou mudanças de expressão facial (categoria1) ou a tecla 2 para o surgimento de outra característica ou faces (categoria 2). Os resultados, analisados com a ANOVA e pós-teste Newman-Keuls, apontam para maior incidência do Fenômeno quando usado o estímulo de face com ambos os olhos direito (p=0,001) e esquerdo (p=0,005), principalmente com relação à categoria 2 (p= 0,0001 com olho direito e p= 0,0004 com olho esquerdo). Concluiu-se que embora o Fenômeno ocorra com maior freqüência, com estímulos de faces, ele não é restrito a faces, podendo ocorrer com outro objeto visual (cadeira). Ele parece estar relacionado à adaptação periférica indutora da ativação top-down das áreas de memória visual relacionadas ao estímulo observado. A maior freqüência observada da face pode ser pertinente à especialização na identificação e reconhecimento deste objeto visual. Em adição, um estudo piloto, usando Ressonância Magnética Funcional (fMRI), mapeou a atividade cortical de 1 (um) sujeito durante a apresentação de uma face posicionada no centro, direita ou esquerda do campo visual. Os resultados, tratados com o teste-t pareado, indicaram padrão de atividade no giro fusiforme. A ativação dessa área aumentou após a repetição dos módulos de apresentação, especialmente quando a face foi posicionada nas periferias direita e esquerda. Portanto, o Fenômeno Muitas Faces pode estar relacionado à ativação sustentada do giro fusiforme

Full textPerceptual activity seems to be impacted by the actions the subject can actually carry out with regard to its environment. Nevertheless, it seems that subject action possibilities are most often considered as objective properties of the environment so that they are generally described as being preparatory to action. This thesis work has been devoted to defending the idea that on the one hand, these possibilities of action are emergent properties of the subject-environment relationship and on the other hand, they are likely to have a constitutive functional role for perceptual activity. In a first series of studies we observed that modulations in the possibilities of action lead to a reversal of the facilitation effects when subjects were to categorize prehensile objects. In a second series of studies we observed that the ability to detect an object among a set of others was impacted by the action potentials suggested by the objects but also modulated by the subject's driving engagement in the task. Finally, in a third series of studies, we have shown that the possibilities of action could play a significant functional role for subject perceptual activity. Indeed, this last work shows that in ambiguous perceptual situations, the way in which an object is categorized seems to depend on the ability of the subject to grasp it effectively. All these results seem to indicate that the action possibilities are properties of the subject-environment coupling and occupy a major place in the perceptual activity. More generally, these works constitute some arguments in favor of taking into account the whole subject-environment situation as well as the importance of the meaning of the subject actions according to the constraints that are exerted on him, here and now

Full textAbstract. Our movements are often coordinated to those of other people. Such interpersonal coordination influences the performance in sport activities but also the success of our everyday social interactions. Previous research led to a better understanding of the perceptivo-motor processes underlying the control of interpersonal coordination and identified the influence of some informational constraints such as how an actor pick up information on the movements observed. It is however often difficult to understand why our movements are more easily coordinated to those of some people. Using the conceptual and methodological framework of the dynamical approach, we aim in this thesis at further understanding the informational constraints influencing the interpersonal coordination dynamics. Collectively, the results of our studies show that interpersonal coordination does not depend only on how information is picked up but also on the nature of this information. We show that the properties of the movements with those we coordinate influence interpersonal coordination. The coordination dynamics depend on the discrete or continuous nature, the amplitude, and the intrapersonal coordination of the movements of the people with who we interact. We also show that the pick up of the information, and more generally, the percetivo-motor processes underlying interpersonal coordination are affected by the pathology such as schizophrenia, and improved by learning, sport skills for example. These results lead to a better understanding of the informational constraints influencing interpersonal coordination dynamics. They represent promising research directions to help people having a deficit of social interactions

Full textIn everyday life, each of us is constantly processing perceptual input from the environment, we collect and then integrate numerous items of sensory information (Calvert & Thesen, 2004). Alongside these perceptual activities, knowledge related to our environment is continually "recovered" from memory. Embodied cognition and grounded cognition theories suggest that cognitive processes (e.g., memory processes, language processes) are grounded in the same sensory-motor systems as those used in perceptual and motor processes (Glenberg, 1997 ; Slotnick, 2004 ; Pecher & Zwaan, 2005).Memory is composed of sensorimotor traces encoded during the several experiences of an individual in his environment (Versace et al., 2009). A large number of studies in cognitive psychology and neurosciences demonstrated that knowledge is constructed and (re)emerged from the activation of neural systems typically associated with perceptual-motor mechanisms. The contents and the functioning of our memory are intrinsically linked to our past and present sensorimotor activities. To be effective, knowledge involved in our cognitive activities must be closely linked to the actual situation. This ability to adapt to specific situations would not be possible unless knowledge, including conceptual knowledge, is derived from the reactivation of memory traces of past experiences (Barsalou, 2008 ; Versace et al., 2014). Conversely, sensorimotor activities are totally dependent on memory traces of past sensorimotor experiences. Thus, the difference between perception and memory is that, in the former, properties are perceptually present, whereas, in the latter, they are absent but reactivated. This PhD research focused on the link between memory and perception and, more precisely, aims to provide arguments in favor of the similarity of memory and perceptual processes that result from the activation of components of same sensorimotor nature. We tested the hypothesis that perceptual effects should be observed with reactivated components in memory. We used well-known perceptual effects (such as masking effect or perceptual bias invisual illusion) to investigate the possibility to replicate these effects by replacing the sensorial present components by reactivated components in memory

Full textThe effects of multiple-site, intradentate, colchicine injections on the performance of a temporal, differential reinforcement of low rates of responding (DRL-20 s) task and a spatial, delayed non-matching-to-place (DNMTP) task in a plus-maze were investigated in rats trained in both tasks prior to the lesion. Quantitative analysis revealed a greater than 86% reduction in the dentate gyrus (DG) of the colchicine-injected rats compared to the sham-operated controls. Dentate gyrus damage rendered rats less efcient than sham-operated controls in the performance of the DRL-20 s task. The DRL inter-response time (IRT) distribution for the DG-lesioned rats and the sham-operated controls was similar; however, while the distribution peak for the control rats was 20 s, it was 16 s for the DG-lesioned rats, indicating that the latter rats underestimated time. Performance of the DG-lesioned rats was also disrupted in the DNMTP task. However, DG-lesioned rats recovered control levels of performance during repeated training with an intertrial interval equal to 3 s. An increase in intertrial interval in lesioned and sham-operated controls disrupted performance in both groups; however, while DG-lesioned rats performed at chance levels when the intertrial interval was increased to 4 min or longer, the sham-operated controls performed at chance levels only when the intertrial interval was increased to 16 min. These results seem most parsimoniously interpreted following the cognitive map theory of hippocampal function.

Full textEmotions influence our behaviour and our perception. Indeed, converging data from neuroscience and experimental psychology point to a facilitated processing of emotional information. This thesis investigated three aspects of the emotional modulation of perception. Using Evoked Related Potentials (ERP) we first tested the specificity of this perceptual facilitation for natural stimuli. To do so, we measured the temporal dynamics of sad emotional expression processing in human and robotic stimuli. In a second study, using ERPs, we tested the likelihood that early visual modulations would occur to stimuli devoid of any visual meaning but which could be taught as having an affective (humorous) or neutral meaning. In our last paradigm, we explored the perceptual consequences of emotional information processing. More specifically, using a psychophysics experiment based on conjoint measurements, we tested the reciprocal effects of the perceived pleasantness of scenes on their perceived contrast. Taken together, our results converge towards the idea that affective processes are potent modulators of several aspects of visual perception. Our results also highlight the impact positive affect on perception, a topic that is less commonly studied in this field of research

Este estudio sitúa la formación del profesorado en RE y las percepciones de los docentes sobre RE en el centro de la investigación educativa. La tesis utiliza un diseño de método mixto secuencial exploratorio y comienza examinando la RE en términos de percepción del profesorado, su potencial y su integración en el plan de estudios, continúa con una revisión de la literatura sobre programas internacionales de formación de profesores y concluye con el lanzamiento de dos programas de formación (piloto, principal) para futuros profesores y con el estudio de sus percepciones sobre RE y el aprendizaje que se ha llevado a cabo. Las conclusiones sugieren que los profesores tienen una visión positiva del aprendizaje de los estudiantes con RE y están a favor de que se integre a los currículos escolares. La duración y los requisitos de los programas actuales de formación del profesorado en RE difieren sustancialmente, mientras que se considera que las mejores prácticas son la colaboración, el diseño de materiales, la instrucción en pedagogía, las oportunidades de práctica y el feedback / soporte. El programa piloto de formación en RE permitió a los participantes integrar la RE en proyectos educativos sobre desarrollo sostenible en diversas disciplinas. Los resultados del principal programa de formación del profesorado, demostró que la RE tuvo un impacto positivo en el aprendizaje y las opiniones de los participantes: i) los participantes integraron la RE en una variedad de proyectos educativos en el área de ciencias naturales, ii) su aceptación y autoeficacia hacia la RE habían mejorado después del programa, iii) tenían opiniones positivas sobre el potencial de la RE.
Teachers are not always capable of integrating educational robotics (ER) into their teaching as they do not often receive training in this area as part of their university degrees. This study places teacher education in ER and teacher perceptions of ER at the center of educational research as they are influencing the integration of ER into the school curriculum. The thesis uses an exploratory sequential mixed method design. It starts by examining ER in terms of teacher perceptions, its potential and integration into the curriculum, continues with a review of the literature on international teacher training programs and concludes by launching two training programs for preservice teachers and studying their perceptions of ER and the learning that has taken place. The findings of the study of teacher perceptions suggest that teachers have a positive view of student learning with ER and are in favor of it being integrated into school curricula even at early educational stages. The duration and requirements of current ER teacher training programs differ substantially, while the best practices are regarded to be collaboration, materials design, instruction in pedagogy, opportunities for practice, and feedback/support. The pilot ER training program enabled the trainees to integrate ER in educational projects on sustainable development in a variety of disciplines. The results of the main teacher training program showed that ER had a positive impact on participants’ learning and opinions: i) participants integrated ER into a variety of educational projects in the area of natural sciences, ii) their acceptance of and self-efficacy towards ER improved after the program iii) they had positive views of the potential of ER, considered teacher training in ER to be useful for their teaching career and made suggestions for improving the training program such as additional training sessions/resources and time for experimentation.

Full textPartitions of tonal music for the piano are a representation of a given set of notes and values taking a number of forms whose variety organize the musical language in a more or less complex way. In his or her first sensorial, motor, and cognitive experience of the text, the reader takes into account the horizontal and vertical axes of music ; His or her visual and motor skills are based on the resources of a self-programming ability acquired through both musical acculturation and practice. Those resources characters with the data particular to the instrument wich allow the music to materialize. This experimental research work aims at analyzing the psychological mechanisms involved in the act of reading partitions for the piano on the basis of several experiments proposed to a sample of subjects composed of 53 learners of 9 to 14 years of age attending music scools and distributed in three groups (first, second, and third degree) and of 10 advanced-level students aged 15 and over. The statistical results show that their altertness in visually discriminating the rhythmical values of notes, their capacities to elaborate a visual and spatial perspective, and their mastery of the keyboard all have a role to play for the building of skills, regardless of the student's level. Besides, the effect of the pianistic level on performance is more visible than the effect of age. The discussion on errors made in reading is intended to open up a new scope for research on the cognitive mechanisms inv

Full textThis research seeks to identify the auditory mechanisms at the origin of the segregation of concurrent sound sources. Certain acoustic cues for segregation are recombined in order to clarify the description. Four series of experiments study the auditory mechanisms responsible for the segregation of stimuli within which these cues are present. The first two series investigate the auditory mechanism underlying the use of the cue incoherent frequency modulation. The next two series are concerned with interactions among four cues. The first series of experiments showed that the detection of auditory beats is not solely responsible for the segregation of a study sound played simultaneously with a sound whose fundamental frequency is either diferent or modulated in frequency. The second series of experiments verified that there exists a mechanism which can compare the outputs of different auditory frequency channels and detect whether their frequency modulations are incoherent. If the number of frequency regions contaiging the incoherence is greater, the detection is easier. The auditory system can also combine the information from neighboring frequency channels that have coherent responses. The third series of experimented focussed on the mutually reinforcing interactions among four segregation cues for concurrent sound sources: onset asynchrony, amplitude modulation incoherence, frequency modulation incoherence, and polyperiodicity (or the presence of compenent signals whose periods are different and not integer multiples of one another). The presence of several segregation cues results in an improvement over the performance obtained with a single cue. A predominance of one cue over another is not generally observed, with the exception of amplitude modulation which seems to be a less important cue than the others. The last series of experiments showed that the frequency modulation coherence cue succeeds in reducing the effect of the polyperiodicity cue, but does no have an influence on an intensity difference cue

Full textThe second study introduces a novel rivalry phenomenon produced by overlapped upright tilted faces. The results indicate that this effect is dependent upon orientation with overlapped inverted faces being perceived as ambiguous in a majority of trials. The third study further examined the factors underlying this rivalry effect. It was found that contrast reversal did not influence the rivalry effect produced by overlapped upright faces and that overlapped houses did not produce rivalry. Results from both studies were taken as evidence that faces are more readily processed as Gestalts compared to other complex objects and therefore engage domain specific operations. The results also suggest that fast operations underlie perception of a face as a Gestalt. Finally, it was suggested that the rivalry effect produced by overlapped faces may illustrate informational encapsulation in face perception.
In the fourth study, faces were used to investigate the relationship between attention and modular functions. Three separate experiments showed that faces and houses compete for attention. This finding suggests that the face perception module does not have its own dedicated attentional resources but rather shares a common pool with other visual processes. Results from one experiment also suggested an advantage for faces in the allocation of attention at very short presentation times. This advantage was postulated to arise from two interacting mechanisms that is, faces capture attention over other objects and faces are more automatically encoded than other objects. Together, these studies indicate that a modular conceptualization of face processing is both appropriate and useful. They also demonstrate the utility of faces for investigating cognitive mechanisms that mediate modular functions.

Full textUnderstanding others’ motor behaviour is part and parcel of Humans’ social experience. According to scientific literature, we rely on specific mechanisms for perceiving human bodies (whether static or moving) on the one hand, and processing emotional facial expressions on the other hand. This thesis aims to understand to what extent the emotion conveyed by a person’s face can modulate one’s perception of her/his motor action. Results of study 1 showed that our estimation of an individual’s static equilibrium is modulated by the observed individual’s emotional facial expression (smiling or tensed). Study 2 focused on perceptual estimation of the physical effort developed by a person on the basis of his facial expression of pain alone. Results revealed that participants adopt two automatic perceptual mechanisms. The first, highlighted via functional measurement, facilitates estimating the intensity of effort pain felt by others. The second, evidenced by measuring memory bias, leads to an automatic anticipation of the subsequent changes in the intensity of pain-related facial expressions. Study 3 showed that the estimation of physical effort developed by a paraplegic individual performing a transfer movement is modulated by two pain behaviours (guarding and facial expression of pain). Interestingly, this modulation varies with participants’ familiarity with both the medical domain and paraplegia. The conclusion of this research suggests that the modulation of emotional perception related to others’ motor action is primarily subtended by an automatic (bottom-up) process and an implicit emotional contagion. However, the latter can be inhibited by an explicit (top-down) process which may depend on (1) the type of inference made on others (estimating postural balance or physical effort developed in others), and (2) the familiarity of the observer with motor action and facial expressions

Full textSelection is crucial in vision. Visual selection depends on the saliency and the attributes of the objects. On the other hand, the programming of a saccadic movement towards an object also influences visual selection. The experiments of my thesis show that more than 130 msec before the saccade onset, visual selection operates on the basis of stimulus-driven attributes. Then, between 80 and 130 msec before the saccade triggering, the saccade-driven selection process operates in parallel with the stimulus-driven selection. Later, less than 80 msec when the saccade is imminent, the visual selection process operates only on the basis of the saccade-driven selection. At this time during the saccade preparation, a strict spatial coupling is observed between the perception and the saccade end point calculation. Overall, these results demonstrate that the selection processes for action and perception are dissociated before being coupled at the saccade end point calculation

Full textThe question of crossed categorization in an organization can fit well into a perspective of societal psychology, favouring positional and ideological explanations of this fact (Doise, 2000). In this perspective, this research aims to show the effects of crossed memberships on perceptions between professional groups, and also to study, in a more modest manner, certain differences introduced by variables linked to the work situation, and by factors such as motivation and personality. Three perceptive variables are studied : the perception of the value of groups, of the value of social relationships and of intragroup variability. The main study was carried out on a population of 315 doctors and nurses of both sexes working in hospitals. The results reveal normative processes at work in intergroup perceptions, showing why it is necessary to complement the study of cognition with a study of ideology. Mechanisms of categorical salience between professional and sexual status emerge. Forms of implicit discrimination between the professional groups studied can be seen. The consideration of the distinction between desirability and utility (Beauvois 1990, 1994, 1995) gives a clearer understanding of the dynamic of intergroup biases. The description of perceptive strategies of dominants is given great importance. Definitively, positional variables alone influence the perception of groups and of social relationships. Situational, motivational and personality factors considered only have a slight impact, limited to some perceptive content. It is, however, important to note that judgments of intragroup variability are influenced by the numerical status of groups present rather than by the categorical memberships of the participants

Full textIn humans, voice conveys heterogeneous information such as speaker’s identity, which can be automatically extracted even when language content and emotional state vary. We hypothesized that the ability to recognize a speaker considerably varied across the population, as previously observed for face recognition. To test this hypothesis, a short voice recognition test was delivered to 1120 subjects in order to observe how voice recognition abilities were distributed in the general population. Since it has been previously observed that there exists a considerable inter-individual variability in voice-elicited activity in temporal voice areas (TVAs), regions along the superior temporal sulcus/gyrus (STS/STG) that show preferentially activation for voices than other sounds, the second aim of this work was then to better characterize the link between the behavioral and neural mechanisms underlying inter-individual variability in voice recognition processes through functional magnetic resonance imaging (fMRI). The results of a first fMRI study showed that functional connectivity between frontal and temporal voice sensitive regions increased with voice recognition scores obtained at a voice recognition test. Another fMRI study showed that speaker’s identity was treated in an extended network of regions, including TVAs but also frontal regions and that voice/non-voice classification accuracy in right STS increased with speaker identification abilities. Altogether, these results suggest that voice recognition abilities considerably vary across subjects and that this variability can be mirrored by different neural profiles within the voice perception network

Full textThis thesis was about visual selective attention, toward non-spatial features, that is, the ability to favour the perceptual processing of some objects in the visual scene, at the expense of others. In particular, the aim was to study, through visual search experiments, the various possible interactions between endogenous (linked with incentives and knowledge of subjects) and exogenous (linked with perceptual properties of the objects) processes. The first series of experiments showed long-lived salience effects. These salience effects could, hewever, be favoured or overriden by endogenous processes (induced by cueing the target size), and modulated by perceptual priming. The second series evidenced that resisting the interference induced by a salient distractor depended on central attentional resources, and was modulatted by perceptual load. Finally, the third series demonstrated that separate endogenous and exogenous signals could genuinely integrate. This integration could not be accounted for by a race between strictly independant signals, as evidenced by the falsification of the Miller's (1982) inequality. This integration might occur in the perceptual system. Theglobal set of data highlighted the flexibility of endogenous attentional control, and invited developping a general model of visual selective attention, on the basis of the biased competition hypothesis

O objetivo é identificar a relação existente entre o processo perceptivo dos fatores ambientais e a fadiga cognitiva nos operadores de monitoramento eletrônico nas empresas de vigilância privada. Este estudo se justifica em função da necessidade de gerar conhecimento acerca das consequências do processo de trabalho em monitoramento eletrônico tendo em vista a incidência da possibilidade de síndromes de origem da fadiga mental. A pesquisa se desenvolveu no período de agosto a dezembro de 2009, através de um estudo de caso em uma empresa do Estado de Santa Catarina e a amostra é composta de 42 operadores de monitoramento eletrônico, sendo que a metodologia utilizada foi a de elaboração de um construto que relaciona variáveis ambientais na possibilidade de geração de fadiga cognitiva, relacionando-o com NASA-TLX. Os resultados demonstraram uma alta correlação entre os fatores ambientais e a fadiga, especialmente, no que se refere a cognição e a cinestesia.

Full textWithin each breath, a large diversity of volatiles molecules of the surrounding reaches our olfactory receptors. Despite the chemical complexity of the natural environment, the organisms succeed to represent their world using single odorants or mixtures. The treatment is then based on two processes: the elemental mode, which allows extracting the odor quality of all or some of the elements, or the configural mode which allows the holistic representation of the mixture. In this doctoral thesis, we evaluated the influence of some physicochemical parameters, the number of odorants included in a mixture and the developmental stage of an organism in the perception of mixtures in the rabbit and the Human. The results confirm that the perception of configurations is shared by the two models even if the modality of their emergence can be distinct, at least in part. Our findings support the idea that in mixture, several elements or association of elements can carry a perceptual weight leading to the elemental, or configural perception, respectively. These weights can be influenced by several mixture physicochemical parameters, especially their complexity, but can also be partially modified by experience and development. Finally, these works brings original results allowing to better understand how an organism, at different period of its individual life, achieves the extraction of biologically relevant odorants or mixtures of odorants from the highly chemical environment
