Abstract(s)
O presente estudo visa o desenvolvimento de uma
versão adaptada para a população portuguesa do Teste
de Nomes de Categorias Específicas (McKenna, 1997).
Trata-se de um instrumento de rastreio e avaliação
neuropsicológica que permite identificar um défice
caracterizado por uma dificuldade em nomear objectos
das quatro categorias semânticas seguintes: Animais,
Frutos e Legumes, Objectos Práxicos e Objectos Nãopráxicos.
O original inglês apresenta-se sob duas formas:
uma produtiva – a nomeação de imagens, e
outra receptiva – o reconhecimento de imagens, podendo
este ser feito a partir da palavra falada ou da palavra
escrita. Foi desenvolvida em português a versão
de nomeação, que foi aplicada a 56 indivíduos saudáveis
do ponto de vista neurológico (grupo de controlo
total) e a um grupo de 24 pacientes neurológicos com
lesão cerebral unilateral (grupo clínico). O grupo clínico
foi emparelhado com um subgrupo de controlo
constituído por indivíduos com características semelhantes
em termos de idade, escolaridade e sexo. Os
resultados obtidos no grupo de controlo total mostram
um interacção entre categoria e sexo, e um efeito principal
de categoria. Verificou-se também que o grupo
clínico obteve, em todas as categorias, resultados
significativamente mais baixos do que o subgrupo de
controlo emparelhado, o que neste estudo exploratório
indicia a validade do instrumento.
ABSTRACT: We present a study based on the Category-Specific Names Test developed by McKenna (1997), that we are presently adapting to Portuguese. This test examines naming and identification of items in four categories, two of living things and two of manufactured objects: Animals, Fruits & Vegetables, Praxic Objects and Non-praxic Objects. It allows the detection of naming and identification difficulties, that may be category- specific. We prepared a version of the naming task in Portuguese and examined 54 adults without brain damage (control group; 33 males) and 24 patients with unilateral brain lesions (16 left-, 8 righthemisphere patients). A subgroup of the healthy adults was matched on a one-to-one basis to the brain lesioned patients, such that age, sex and years schooling were equivalent in both groups (the patients were overall older and less schooled). The results of the 155 control group showed a main effect of category – Fruits & Vegetables reached higher percent correct responses – and an interaction between sex and category: women were better with Fruits & Vegetables, men were better with Animals. A difference of 20% in overall performance was observed between younger adults with more years of schooling and older, less schooled, adults. We propose that this difference is an effect of schooling. The comparison of the matched controls and the brain lesioned patients revealed a significant decrease in the patient group.
