A visão através dos contrastes

O primeiro estágio de processamento da informação do estímulo visual consiste na contagem de fótons pelas células fotorreceptoras. Nos estágios pós-receptorais a informação de intensidade absoluta do estímulo é transformada em comparações de informações provindas de áreas adjacentes da retina e momentos sucessivos. Essa métrica implementada pelo sistema visual para quantificar o estímulo é chamada de contraste - contraste espacial ou simultâneo e contraste temporal ou sucessivo. A presença de contraste é essencial para a geração de percepção visual consciente no domínio do espaço e do tempo e em três dimensões ortogonais de cores - branca e preta; azul e amarela; verde e vermelha. Uma curva em forma de sinodelimita os limiares de detecção de contraste em função da frequência especial ou temporal do estímulo. Ela é chamada função de sensibilidade ao contraste e é afetada por uma série de fatores ópticos e neurais. Neurônios de diferentes classes contribuem para regiões diferentes da função de sensibilidade ao contraste e suas atividades representam as ações de vias de processamento visual que se estendem da retina ao córtex visual. Investigações básicas e clínicas têm dado suporte à importância do estudo da sensibilidade ao contraste espacial de luminância (branco e preta) como uma ferramenta indicadora da função visual em sujeitos normais e afetados por disfunções neuro-oftalmológicas.

Percepção viso-motora de escolares com Transtorno do Déficit de Atenção com Hiperatividade

PURPOSE: The aim of this study was to characterize and to compare the visual-motor perception of students with Attention Deficit with Hyperactivity Disorder (ADHD) with students with good academic performance. METHODS: Forty students from 2nd to 5th grades of an elementary public school, male gender (100%), aged between 7 and 10 years and 8 months old participated, divided into: GI (20 students with ADHD) and GII (20 students with good academic performance), paired according to age, schooling and gender with GI. The students were submitted to Developmental Test of Visual Perception (DTVP-2). RESULTS: The students of GI presented low performance in spatial position and visual closure (reduced motor) and inferior age equivalent in reduced motor perception, when compared to GII. CONCLUSION: The difficulties in visual-motor perception presented by students of GI cannot be attributed to a primary deficit, but to a secondary phenomenon of inattention that interferes directly in their visual-motor performance.

Análise da relação entre a habilidade de integração visuo-motora e o desempenho escolar

Visual-motor integration is a skill that involves visual perception and eye-hand coordination. Deficit in perceptual ability and motor organization capacity may reflect in reading, writing and arithmetic learning difficulties. This study aimed to verify the relationship between visual-motor integration ability and academic performance, as well, whether visual perception ability was correlated with reading performance and whether motor coordination ability was correlated with writing performance. Participants were 77 students in the 2nd. year of elementary education at a public school. To data collect were applied the Developmental Test of Visual-Motor Integration and the Academic Performance Test. The results showed a significant correlation between visual-motor integration ability and academic skills of reading (r = 0.230, p = 0.044), writing (r = 0.244, p = 0.033) and arithmetic (r = 0.277, p = 0.015). In addition, was also identified significant correlation between visual perception and reading performance (r = 0.407, p = 0) and between the motor coordination and cursive writing (p = 0.039). The results of this study are consistent with the literature, concerning the verification of visual-motor integration, visual perception and motor coordination abilities influence on the students performance in school activities.

Tarefas de triangulação com restrições perceptuais em pessoas com deficiência auditiva: um estudo por meio de gps

This study aimed to investigate how people with hearing disability perform tasks of distances estimation for locomotion and navigation when deprived of effective perceptual and proprioceptive information. For this, participants with hearing disability went three distances being the first and second 100 meters and the third 140 meters (triangulation) from a source point in an inverted L open field trajectory and then returned to the origin, and the first two were driven by a researcher guide with adapted GPS coordinates of the study, and the third being three free-form sessions, the first one without any perceptual and proprioceptive restriction, the second without visual perception, and the third on the wheel-chair, that is, without proprioception. The results showed that people with hearing disability without the knowledge of the path do not possess satisfactory accuracy but when they learn the way even with the restriction of visual perception and proprioception they can return to the starting point in a task of triangulation. The "t" students test with a significance level of 5% (2.131) indicates significant differences between the first task without any perceptual restriction and the third where they performed in the wheelchair. To achieve these results we used remote monitoring via GPS and the TrackMaker software.

O design no contexto histórico da arte: uma visão da arte e do design a partir do ornamento

Drawing an equivalence analogy between the subjects of style and the ornamentation, the study leans on Aloïs Riegl's theory in order to sketch an anthropological reflection for the appearance of the design and some of their respective confluences with the art. Enriched by the progresses that the psychology of the visual perception provided to the contemporary understanding for the artistic representation, and consequently of this historicity, breaks of the hypothesis that this appearance has given in a process naturally evolutionary, aiming at to supply an inherent human need.

Geografia e imagem publicitária: um diálogo possível

The aim of present work is the interpretation of a Coca Cola soft drink advertising image that is shown on a billboard in the city of Presidente Prudente, in São Paulo state. The billboard shows a scene of the video titled Happiness Factory which was presented on television in 2008. Decoding this kind of image, which is integrated to the theoretical and methodical option, favors the visual perception of shapes and their meanings as a reading of the image and the inclusion of the studies of phenomenology of cultural geography to the social reality could reveal some other dimensions, such as the symbolic, the imaginary, the aesthetic ones.This fact will contribute to widen the social trait of Geography and it represents our object of study.The reading will be done after some reflexion on the function of an external advertisement, that is, within the urban context of Presidente Prudente when refering to billboard being studied. It will also be discussed the importance of becoming a critical reader when interpreting advertising messages presented by the communication means in general.
