NEGATIVE SIDE EFFECTS OF NONCONTINGENT REINFORCEMENT

Noncontingent reinforcement (NCR) has emerged as a treatment package for severe behavior problems. Although concerns about potential side effects (such as incidental reinforcement) have been raised, there have been few reported negative side effects in published studies to date. In this article, we report an NCR treatment evaluation for severe aggression that produced (a) an extinction burst and (b) incidental reinforcement. These side effects were evaluated by examining within-session response patterns and response distributions. As a solution, a brief omission contingency was added to the reinforcement schedule. The omission contingency resulted in decreased aggression rates.

Sex-role preferences in four age levels

Brown's (1956a; 1956b) influential finding that girls of all ages exhibit masculine rather than feminine sex-role preferences has been challenged by the argument that the scale used in his studies—the It Scale for Children (ITSC)—is masculine biased. The present investigation reexamined this issue with an instrument designed to be free of the limitations inherent in the ITSC. Boys and girls from grades 2, 5, 8, and 11 examined drawings of activities scaled for sex-role stereotypy and selected those activities they would like to engage in. Consistent with Brown's earlier work, boys exhibited strong masculine preferences at all ages. Contrary to Brown, however, girls did not show similar masculine preferences. Instead, their choices reflected strong feminine preferences throughout the spectrum of ages tested.     

Creative problem solving as a result of majority vs minority influence

A comparison of influence processes exerted by a majority versus a minority is made, both theoretically and empirically. In this study, comparing the two processes in the same experimental setting, it was hypothesized that subjects would ‘follow’ the majority more than the minority, that is, they would be more influenced to adopt the exact same position. However, it was predicted that subjects exposed to the minority would be stimulated to find new solutions to the problem, solutions that were not offered by the minority but that the subjects would not have found by themselves. Further, these solutions would tend to be correct rather than incorrect. Results support these predictions.     

The effect of children's spontaneous cognitive sets on discrimination learning

Two experiments investigated the role of children's spontaneous cognitive “sets” in pictorial discrimination learning. Lists were constructed to highlight either perceptual or conceptual similarities among the stimuli. In each experiment age by treatment interactions revealed that in comparison to the behavior of older children (sixth graders), that of younger children (kindergartners) is governed more by the perceptible than by the conceptual attributes of stimuli—data in complete accord with Bruner's view of cognitive development.     

A workshop model for training the school psychologist in drug education and intervention techniques

Proposed to: (1) design a model drug training program specifically for graduate student school psychologists, (2) implement the program on a pilot basis, and (3) demonstrate an approach to evaluate the program's effectiveness. A 26-hour drug education workshop was presented to 12 graduate student school psychologists as a model training program including a variety of teaching procedures and extensive evaluation. On prepost questionnaires, improved scores reflected increased understanding of drug-related laws and terminology. While participant's ratings of their knowledge about drugs did not increase, they did rate themselves as more competent regarding drug problems. The workshop's affective climate and many of the teaching techniques were rated positively. The contributions of this workshop were its focus on training techniques and the development of one approach for evaluating training projects for school psychologists.

Mistreatment of an esteemed other as a consequence affecting dissonance reduction

Recent research has shown that aversive behavioral consequences affect the magnitude of dissonance reduction. The present experiment was conducted to help clarify the meaning of an aversive consequence. In previous research, an aversive event was manipulated by having a subject believe that a counterattitudinal speech he had delivered was successful in convincing one of the subject's colleagues. In the present study, it was argued that convincing a colleague is aversive only to the extent that the colleague is liked. This reasoning was tested in a 2 × 2 factorial experiment in which subjects delivered a counterattitudinal speech to a recipient whom either was or was not liked by the subject and either was or was not convinced by the subject's speech. It was predicted and found that the subject would evidence attitude change only in the condition in which the speech led to the aversive event of successfully convincing an esteemed other. The results were discussed in terms of refining the relationship between attitude discrepant behavior and attitude change.
