This study was designed to examine effects of differences in age, health, education, and sex on state and trait anxiety, and to assess interrelations between anxiety and performance on reasoning and problem solving tests. A significant main effect of health status was obtained for trait anxiety, but age, education, and sex effects were nonsignificant for both anxiety variables. Anxiety ratings were inversely correlated with performance on tests of reasoning and problem solving (traditional and practical Piagetian tasks, matrices, and similarities), but the pattern of intercorrelations was stronger within the middle-aged (40-59 years) as opposed to the elderly (60-79 years) groups. The findings fail to support the hypothesis that anxiety increases with age, or that the elderly are disproportionately affected by anxiety in testing situations.
