Reward contingencies and other extrinsic constraints on behavior can lead to reduced levels of interest in and/or decreased engagement in a target activity in a subsequent noncontingent situation. It has been hypothesized that this effect is caused by a change in the self-perceived locus of motivation from intrinsic to extrinsic. It follows from…

This paper addresses some of the practical ways by which students can be given information about the adequacy of their responding. The author views this information as all that is frequently necessary to alter an inappropriate behavior. Thus, he considers feedback to be the first step in most behavior management programs. Studies to determine how…

The effects of different schedules of noncontingent reward on subsequent learning in children were investigated. In the first phase of the experiment subjects performed a block-design matching task and received one of three schedules of noncontingent reward, i.e., continuous reward (Group CRF), random reward on 50% of the trials (Group 50R), or no…

Some of the unique characteristics of the drug abuse field which distinguish it from the other varieties of substance abuse and research methodologies for studying determinants of drug self-administration behavior which have been developed in response to these characteristics were investigated. Data suggest that residential drug…

Many criticisms of Fiedler's contingency model focus upon the LPC (Least Preferred Coworker) scale. The characteristics of the LPC scale were investigated in two studies. Experiment 1 focused upon determining the factor structure of LPC and relevance ratings, while Experiment 2 dealt with relationships among LPC, relevance, and self-ratings.…
