This 2-wave panel survey of young people was conducted to explore the relationship between attitudes and viewing over time, examining aggressiveness and viewing of programs portraying physical and verbal aggression. Questionnaires were administered to 227 children in the fourth, sixth, and eighth grades in 1976 and again one year later. The pertinent variables in this analysis are exposure to physically and verbally aggressive programming, and reports of physical and verbal aggressiveness. Of secondary importance are measures of program prohibition, grade, and sex. This study provides supportive evidence for selective exposure to aggressive television entertainment programming which is compatible with aggressive attitudinal predispositions. Even with a conservative regression analysis that controls for grade, sex, and initial viewing patterns, a significant relationship remained between prior orientations and subsequent program choices. Findings of this study suggest that a portion of the basic relationship between viewing and aggressiveness may be attributable to selective exposure rather than the reverse viewing-causes-aggression sequence.
