Abstract(s)
O reconhecimento de identidade tem vindo a demonstrar-se uma tarefa fundamental, não só
ao nível das relações interpessoais, mas também no desempenho de determinadas profissões
que exigem um rápido processamento cognitivo na identificação de duas faces como sendo a
mesma ou faces diferentes, como é o caso dos seguranças aeroportuários. Um estudo anterior
encontrou, como resultados complementares, que indivíduos alexitimicos tendem a processar
esta informação mais rapidamente que indivíduos não alexitimicos. Deste modo, a presente
investigação propõe-se a estudar as diferenças na velocidade de processamento de
reconhecimento de faces e emoções entre indivíduos alexitimicos e não alexitimicos.
Para tal utilizamos a Toronto Alexithymia Scale (TAS) para avaliar os níveis de alexitimia da
amostra e recorremos à Radboud Faces Database (RaFD), uma base de dados de fotografias de
pessoas reais que correspondiam a determinadas características adequadas a esta
investigação, para construir a experiência que permitiu a recolha dos dados.
O principal objetivo consistiu em comparar as pontuações obtidas no TAS com a Taxa de
Acerto e o Tempo de Resposta Médio da amostra. Desta feita, pretendemos verificar possíveis
diferenças na velocidade do reconhecimento de faces e emoções entre sujeitos alexitimicos e
não alexitimicos. Assim, relativamente aos resultados, é possível concluir que nenhum deles é
estatisticamente significativo, o que sugere que não existem diferenças entre os grupos. Por
fim, em relação à discussão, nenhuma das hipóteses colocadas se comprova após as análises
efetuadas, o que os permitiu realizar algumas reflecções e sugestões que consideramos
pertinentes.
Identity recognition has been shown to be a fundamental task, not only at the level of interpersonal relations, but also in the performance of certain professions that require a rapid cognitive processing in identifying two faces as the same or different faces, such as case of airport security. A previous study found as complementary results that alexithymic individuals tend to process this information quicker than non-alexithymic individuals. So, the present research aims to study the differences in the processing speed of face and emotion recognition between alexithymic and non-alexithymic individuals. To do this, we used the Toronto Alexithymia Scale (TAS) to evaluate the levels of alexithymia of the sample and used Radboud Faces Database (RaFD), a real-life photo database that matched certain characteristics suitable for this research, to build the experience which allowed for the collection of data. The main objective was to compare the scores obtained in the TAS with the Hit Rate and the total response time of the sample. So, we intend to verify possible differences in the speed of the recognition of faces and emotions between alexithymic and nonlexylexic subjects. And, with respect to the results, it is possible to conclude that none of them is statistically significant, which suggests that there are no differences between the groups. Finally, regarding the discussion, none of the hypotheses put forward proves after the analyzes performed, which allowed them to make some reflections and suggestions that we consider pertinent.
