Study investigated the effectiveness of reinforcement in an observational paradigm where the dependent variable was indicated by increased morphological resemblance of an observer (O) after viewing a model (M). The stimulus was a series of novel responses recorded on videotape with each child viewing the tape individually. The subjects were 32 Head Start males divided into four groups. The first group was administered verbal praise prior to the modeling session. The second served as the vicarious reinforcement condition and observed an adult praise the model. The third group received direct reinforcement during the test for acquisition. The control group received no reinforcement along any dimension. The analysis showed only the post-reinforcement group imitated significantly more than the control group.
