Abstract
The stimulus factors responsible for the superiority of reversal over nonreversal shifts in concept formation were analyzed. 2 factors confounded in reversal shifts, within-dimension shifts and response reversals, were isolated for experimental investigation. Using card-sorting tasks, groups making only within-dimension shifts learned more rapidly than groups making both within-dimension shifts and response reversals. Both groups learned quicker than comparable groups making between-dimension shifts. The results indicate that within-dimension shifts are an important factor in the rapid acquisition of reversal shifts, and response reversals may impede learning. In this transfer-of-training situation, positive transfer occurs when the stimulus dimension on which discrimination is based is kept constant, but the specific stimuli used are changed.
