Abstract: Attempted to determine whether the sanctioning behavior of naive trainers is consistent with principles of behavior modification, that is, responsive to a trainee's performance alone, or whether it is influenced by variables other than performance. 2 variables which may affect the administration of rewards and punishments are the perceived competence of the trainee and difficulty of the task. These 2 variables were manipulated in a 2 * 2 factorial design with easy and difficult tasks and competent and noncompetent trainees. The trainers were responsible for administering rewards and punishments to trainees while teaching them a concept task; use of a confederate enabled identical trainee performance for all conditions. The data indicate that extraperformance variables do affect the reinforcing behavior of naive trainers as predicted by attribution theory. The results provide behavioral confirmation for predictions from the theory which has been primarily tested using perceptual judgmental data.
