BANHATO, Eliane Ferreira Carvalho  and  NASCIMENTO, Elizabeth do. Executive functions in elderly: A study using WAIS-III Subtests Scale. PsicoUSF [online]. 2007, vol.12, n.1, pp.65-73. ISSN 1413-8271.

Evaluating executive functions is relevant because of their presenting premature decline with age. It's necessary to make instruments for research and evaluation of elderly people available due to the increase of this population. This transversal study had as its objective the evaluation of executive functions of elderly people using five sub tests of WAIS-III identifying associations with age, gender and level of instruction. The communitarian sample consisted of 346 elderly people with average age of 74,14 years (DP = 8,49) and level of instruction of 7,2 years (DP = 4,5). The validity of construct was measured with tests of Verbal Fluency (convergent) and CES-D (divergent). Univariate Analysis have determined significant difference according to gender, with better masculine performance. Age correlated negatively and significantly to executive tasks. Level of instructions affected the processing speed, but not the attention, reasoning and visual, motor and perceptive organization. The study conclusion was in favor of the adequacy of the sub tests for executive evaluation of elderly people. The establishment of limit points is recommended in order to make the differentiation between normal and pathological aging possible.
