THE USE OF PEER MONITORS TO REDUCE NEGATIVE INTERACTION DURING RECESS

The negative interactions of a mildly retarded child, Dennis, were reduced in three daily recess periods, withthe use of a point system. Adult monitors initiatedthe intervention inthe morning recess; reductions achieved during adult monitoring were maintained in that recess during two subsequent conditions: peer monitoring and self-monitoring. Dennis' negative interactions were reduced next inthe afternoon recess by peer monitors. Again, reductions were maintained during a subsequent self-monitoring condition. Finally, duringthe noon recess, Dennis was trained to serve as a peer monitor for Ed, a moderately retarded classmate. Dennis' rate of negative interactions quickly decreased following his appointment as a peer monitor. The results show that a point system, originally designed for adult monitoring, can be adapted without loss of program effectiveness for peer monitoring or self-monitoring. The results also suggest that classmates who serve as peer monitors may benefit significantly from their role. The conditions under which these therapeutic effects occur andthe role that treatment order effects may play in this process require further investigation.     

THE EFFECTS OF RECIPROCAL PEER TUTORING AND GROUP CONTINGENCIES ON THE ACADEMIC PERFORMANCE OF ELEMENTARY SCHOOL CHILDREN

We evaluated the effects of reciprocal peer tutoring combined with group reinforcement contingencies on the arithmetic performance of 12 underachieving fifth-grade students. Results indicated that the intervention increased the students' arithmetic performance to a level indistinguishable from their classmates during treatment and 12-week follow-up phases. Pre-, post-, and follow-up sociometric data indicated that the students who participated in the treatment groups increased their amount of peer affiliation with other treatment group members.     

Verbal self-reports of delayed matching to sample by humans

Undergraduates participated in two experiments to develop methods for the experimental analysis of self-reports about behavior. The target behavior was the choice response in a delayed-matching-to-sample task in which monetary reinforcement was contingent upon both speed and accuracy of the choice. In Experiment 1, the temporal portion of the contingency was manipulated within each session, and the presence and absence of feedback about reinforcement was manipulated across sessions. As the time limits became stricter, target response speeds increased, but accuracy and reinforcement rates decreased. When feedback was withheld, further reductions in speed and reinforcement occurred, but only at the strictest time limit. Thus, the procedures were successful in producing systematic variation in the speed, accuracy, and reinforcement of the target behavior. Experiment 2 was designed to assess the influence of these characteristics on self-reports. In self-report conditions, each target response was followed by a computer-generated query: “Did you earn points?” The subject reported by pressing “Yes” or “No” buttons, with the sole consequence of advancing the session. In some cases, feedback about reinforcement of the target response followed the reports; in other cases it was withheld. Self-reports were less accurate when the target responses occurred under greater time pressure. When feedback was withheld, the speed of the target response influenced reports, in that the probability of a “Yes” report increased directly with the speed of accurate target responses. In addition, imposing the self-report procedure disrupted target performance by reducing response speeds at the strictest time limit. These results allow investigation of issues in both behavioral and cognitive psychology. More important, the overall order in the data suggests promise for the experimental analysis of self-reports by human subjects.     

Response deprivation and reinforcement in applied settings: A preliminary analysis

First-grade children engaged in seatwork behaviors under reinforcement schedules established according to the Premack Principle and the Response Deprivation Hypothesis. Across two experiments, schedules were presented to the children in a counter-balanced fashion which fulfilled the conditions of one, both, or neither of the hypotheses. Duration of on-task math and coloring in Experiment 1 and on-task math and reading in Experiment 2 were the dependent variables. A modified ABA-type withdrawal design, including a condition to control for the noncontingent effects of a schedule, indicated an increase of on-task instrumental responding only in those schedules where the condition of response deprivation was present but not where it was absent, regardless of the probability differential between the instrumental and contingent responses. These results were consistent with laboratory findings supporting the necessity of response deprivation for producing the reinforcement effect in single response, instrumental schedules. However, the results of the control procedure were equivocal so the contribution of the contingent relationship between the responses to the increases in instrumental behavior could not be determined. Nevertheless, these results provided tentative support for the Response Deprivation Hypothesis as a new approach to establishing reinforcement schedules while indicating the need for further research in this area. The possible advantages of this technique for applied use were identified and discussed.     

Achievement goals and improvement following failure: moderating roles of self-compassion and contingency of self-worth

We examined whether mastery goals promote greater score improvement on a cognitive test than performance goals and whether self-compassion and contingency of self-worth moderated the effect. Participants received either mastery or performance goals manipulation, failed on a difficult test, and took the test again after receiving the correct answers. Those with mastery goals showed a greater score improvement than those with performance goals, although post-failure state self-esteem did not differ between the two conditions. Moreover, the goals had a greater effect among (a) those with low rather than high self-compassion and (b) those with high rather than low competition contingency of self-worth. The findings suggest that by framing the task as a challenge rather than a threat, mastery goals encourage people to learn from failure more so than performance goals, especially when under high ego-threat.
