This investigation assessed the ability of subjects to maintain a set
in the face of varying demands on perceptual persistence via the Stroo
p Color-Interference Test. Forty-two African American adults with unre
markable neurological and psychiatric histories served as the research
participants. Participants were administered a modified version of th
e Stroop (Comalli version). In the current study, significant gender d
ifferences were noted on the total time to complete the Color Naming a
nd Word Reading cards, with women out-performing men. These preliminar
y results represent an attempt to address the need for more normative
data on this population.
