Ambivalent proaction following common label pretraining

Abstract

Twenty Ss were assigned to each of three experimental treatments, the transfer effects of which were assessed in a subsequent discriminative motor task. One group learned different verbal responses to each of six test•task stimuli (24-point random shapes), while Ss in a second group learned two such responses to clusters of three of the same stimuli_ A co trol group learned two verbal responses to clusters of different stimuli. Reliable differences were obtained between the treatment groups in terms of total test-task errors and two component error measures. An apparent interaction was observed between speed of original learning, treatment, and component error type.
