Cautiousness and visual selective attention performance among older adults.

Cautiousness has been implicated in the literature as a possible factor responsible for observed performance decrements among older adults in a number of research paradigms. This study sought to assess whether the speed and accuracy of performance on a perceptual-cognitive task (the Stroop Color-Word Interference Test) differed significantly for more and less cautious older adults. The participants (N = 41), ranging from 55 to 81 years of age, were classified as either more cautious (n = 20) or less cautious (n = 21) on the basis of their responses on a personality test. Results indicated that cautiousness among older adults was manifested more in terms of the accuracy of response (fewer errors of commission) than in terms of the speed of response, and that level of cautiousness increased with increasing age.
