Performance of retardates on the Stroop Color-Word Test

Abstract

Institutionalized retardates were examined on a special format of a task requiring them to name the colors of 36 color patches and to name the color of the ink in which 36 incongruent color words were printed on separate cards. Mean reaction time for the incongruent condition was significantly longer than that for the color patches and the difference was independent of fatigue and stimulus size. The color-word interference effect previously reported with normal populations when given the Stroop test was demonstrated for this retarded sample using a special format.
