Resumo(s)
Indivíduos com surdez profunda dependem fortemente da visão para interagir com o seu meio ambiente. Uma melhoria do desempenho visual como consequência da privação auditiva é assumida na literatura, como resultado de alterações intermodais que ocorrem nos últimos estágios do processamento visual. Pretende-se com este artigo apresentar uma revisão da literatura sobre o tema, de forma a evidenciar diversas abordagens que daí resultaram. Para tal, discutiu-se o conceito e objeto de estudo da Atenção Visual em Pessoas Surdas, procurando demonstrar o desempenho visual face à privação sensorial auditiva. Prossegue-se com a sistematização de várias abordagens ao tema e, em especial, das que se centram nas seguintes tarefas visuais: (i) Orientação da Atenção, (ii) Amplitude do Campo Visual e (iii) Sensibilidade ao Contraste. Grande parte da investigação tem sustentado a ideia de que a perda da modalidade auditiva em pessoas surdas pode levar a uma melhoria da modalidade visual.
Individuals with profound deafness rely strongly on their vision to interact with the environment. The improvement of visual performance is a result of hearing deprivation and it is assumed by literature as a result of intermodal changes that occur in the last stages of visual processing.This paper aims at presenting a review of literature on this subject, in order to highlight different approaches that result from it. To this end, we discussed Visual Attention in Deaf as a concept and as an object, seeking to demonstrate the visual performance in comparison with the auditory sensory deprivation. It is followed by the systematization of the different approaches to the subject and, in particular, those that focus on the following visual tasks: (i) Orientation of Attention, (ii) Central and Peripheral Visual Processing and (iii) Visual Contrast Sensitivity. A great part of the research has supported the idea that the loss of the hearing modality in the deaf can lead to an improvement in the visual modality.
