Adolescents defined as educable retarded who have demonstrated their ability to profit from experiences (highscorers and gainers) were hypothesized to perform more adequately than nongainers on the Stroop Color-Word interference task. The tasks were administered on three successive days to each subject in the following order: color, word, color-word-color, and color-word-word. Performances by highscorers and gainers tended to show less interference than nongainers on the color-word-color task. No significant differences in performance were found on the color or word naming cards, indicating that the groups did not differ on simple basks but on the ability to inhibit a response to a conflictful stimulus and to respond adequately with a minimum of delay.
