Abstract: This study of the effect of self-modeling of positive affective behaviors on high school students' attitudes toward school employs videotaped behaviors of the subjects exhibiting positive attitude toward school. Exposure to the edited positive behavior videotapes occurred 10 times over a four-week period. The subjects were pre and post-tested using the Study Attitudes Survey, a subscale of the Brown and Holtzman Survey of Study Habits and Attitudes. Results of an analysis of variance were not sufficient to confirm or refute the effectiveness of the self-modeling. Recommendations based on this study include the conducting of additional research in three areas: the modeling of attitudes to increase positive affect, the self-modeling of a range of attitudes with subjects of varying ages and numbers, and the refining of what behaviors are indicative of students' attitudes toward school and the process for evaluation of those behaviors.
