Abstract

Devised a color-digit interference task and 2 sorting tasks as variants of the Stroop Color-Word Test and R. Gardner, et al. (see record 1961-02266-001) sorting tasks, respectively. These tasks proved applicable to a mentally retarded sample (n = 39) and provided reliable measures of 2 cognitive control dimensions (constricted-flexible control and equivalence range). As predicted, the main test scores were significantly more variable in retarded Ss than in normals (n = 32). Analyses of performance on the color-digit interference task indicated that retarded Ss were significantly slower than the normals on all parts of the task, particularly under conditions of distraction (whether inherent in the task or externally imposed). Low IQ retarded Ss were significantly slower than high IQ retarded Ss on all parts of the task. The extreme cognitive control test scores of the retarded Ss, the nature of the attentional deficit among these Ss, and the relevance of a cognitive control approach for the training of retarded persons are discussed.
