O papel da cor no acesso aos descritores estruturais dos objetos

Abstract

O objetivo deste estudo visou esclarecer se a propriedade visual cor facilita o acesso aos descritores estruturais de objetos com alto e baixo nível de diagnosticidade de cor. Foi arquitetada uma tarefa de correspondência entre a parte e o todo de forma a avaliar o estádio de reconhecimento de objetos no qual se acede aos descritores estruturais. Nesta tarefa, foi pedido aos participantes para verificarem se uma propriedade visual (e.g., tromba do elefante) correspondia ou não com um objeto apresentado posteriormente (e.g., elefante). Foram apresentados objetos com alto nível de diagnosticidade de cor e com baixo nível de diagnosticidade de cor. Os objetos foram apresentados a cores e a preto e branco. A amostra foi constituída por 100 estudantes universitários. Os resultados mostraram que a cor facilitou a verificação de ambos os tipos de objetos. No entanto a cor revelou-se especialmente importante para os objetos de alto nível de diagnosticidade da cor e para verificar propriedades não salientes. Este resultado sugere que a cor pode ser um atributo visual importante para aceder aos descritores estruturais dos objetos, especialmente quando os descritores estruturais são pouco salientes.
