EVALUATING TREATMENT CHALLENGES WITH DIFFERENTIAL REINFORCEMENT OF ALTERNATIVE BEHAVIOR

In prior research, differential reinforcement of alternative behavior (DRA) has been implemented at optimal treatment values: Problem behavior is never reinforced, and alternative behavior is always reinforced. However, in application, DRA is unlikely to be conducted optimally. In this study, following a functional analysis phase and a differential reinforcement at full implementation phase, we challenged initially positive treatment effects for 3 participants by implementing DRA at less than optimal parameters. For example, some occurrences of problem behavior were reinforced, and some occurrences of alternative behavior were not reinforced. Results suggested that when exposed to DRA at full implementation, participants showed a bias toward appropriate behavior in subsequent conditions during which “mistakes” (treatment challenges) were intentionally introduced. In addition, the negative effects of treatment challenges were quickly reversible, in comparison to the positive effects of DRA, which were not quickly reversible in the face of treatment challenges.     

The role of planning for intention-behavior consistency

Two studies investigated how planning affects intention-behavior consistency. In Study 1 an experimental group and control group which each consisted of 14 undergraduates were requested in computerized interviews to indicate which activities they intended to perform on the following day. Subjects in the experimental group were also requested in a second phase of the interviews to specify when and where they intended to perform the activities. The results showed that activities for which time and place had been specified were more likely to be performed. In Study 2 another 75 undergraduates volunteered to participate in an experiment in which they were requested to perform an activity (reporting mood effects of reading a prose excerpt) by themselves on one of three following days. One group of subjects only agreed to perform the activity, another group agreed to perform the activity as well as indicated when and where they would do it, and a third group in addition to this indicated which other activities they would perform on the same day. In support of the hypothesis that planning an activity increases the likelihood that it will be performed, the results showed that subjects who indicated other activities more frequently performed the target activity. More efficient time management resulting from planning may account for the findings, although further research is needed to show this conclusively.     

Longitudinal effects of preschool behavioral styles on early adolescent school performance

Early behavioral problems and temperament as well as student-teacher relationships each have been shown to be important predictors of school performance. This longitudinal study investigated the relations between children's preschool behaviors and their early adolescent student-teacher relationships and academic achievement. It was hypothesized that preschool behaviors would predict school performance in early adolescents. Results showed that children who were more prone to anxiety as preschoolers tended to have the highest grades as young adolescents. Additionally, children with poor student-teacher relationships, as characterized by dependent and conflictual relationships, had lower grades in school. Thus, in considering the importance of a “child×environment” model for school performance, it appears that it is both the child variable of anxiety and the perhaps environmental variable of student-teacher relationships that are related to school performance.
