Adult age differences in the Color Stroop Test: A comparison between an Item-by-item and a Blocked version

Published in Archives of Gerontology and Geriatrics. 2010, vol. 51, no. 2, p. 135-142
Abstract The Color Stroop Test is consensually considered as a task to assess the efficiency of inhibitorymechanisms. If the Stroop interference effect is largely undisputed, it is also acknowledged that the size of this effect varies as a function of various taskmanipulations, such as the task format. The aimof the present study was to compare the size of adult age-related differences in inhibition as assessed by twodifferent versions of the Color Stroop Test: a standard Blocked paper-and-pencil version and a computerized Item-by-item one. Results showed pronounced age-related differences in the interference effect in the Blocked version, but not in the Item-by-item one. These findings are discussed in terms of the characteristics of the tasks. The choice of the appropriate version with respect to clinical aims is also addressed.
