RESUMO

This study aimed at investigating differences in the performance of the young elderly and oldest old in tasks evaluating cognitive flexibility/inhibition (Stroop test), selective attention/working memory (Digit Span Subtest), premorbid intelligence/semantic knowledge (Vocabulary Subtest), and decision making (Iowa Gambling Task - IGT). Twenty healthy individuals were divided into two groups: 10 young elderly (M = 62 years, SD = 2.1) and 10 oldest old (M = 80 years, SD = 3.3), both with high educational level (M = 14 years of study, SD = 2.5). Results showed that the groups were only different in terms of decision making. There was also a difference in the learning process of each group; the young elderly reached more favorable scores in the IGT.
