Twelve male neat-mute schizophrenics were divided into a model-plus-reinforcement group; a model-only group; and a control group, to test the hypothesis that the presence of a verbalizing model to 35 mm slides would serve as an eliciting stimulus to increase speech output. Significant increases in verbalizations were found over treatment sessions, the model-plus-reinforcement condition showing the most marked improvement. Generalization to the ward was found for only three subjects.
