Differential reinforcement of reaction times in developmental retardates.

Perceptual and Motor Skills
J E Hasazi, R M Allen

Abstract

The effects of differential reinforcement on reaction times to two intensities of reaction signal were investigated in 36 developmental retardates. One group was reinforced for reaction times to the higher intensity signal; a second group was reinforced for reaction times to the lower intensity signal; a third group received no reinforcement. Reaction time decreased as signal intensity increased and decreased over sessions as a function of reinforcement. Likewise, reinforcement either exaggerated or reversed differences in reaction times to each signal depending on the particular reinforcement contingency. Results were discussed in terms of attentional and motivational explanations of effects of signal intensity on reaction times of retardates.
