Children's social interactions are often dependent upon the setting or context in which they occur. The current study explored the school bus as a unique context for social interaction. One hundred and fifty-seven elementary school students (78 males and 79 females), in grades 3, 4, and 5, completed a questionnaire concerning the rate and types of prosocial and aggressive behaviors that occur on the school bus ride. Overall, findings indicated that students were prosocial more often on the school bus than they were aggressive. Regarding the types of social behaviors, differences found in the current study were distinctive. Participants mentioned non-traditionally studied prosocial behaviors (e.g., companionship and benevolence) more often than traditionally studied behaviors (e.g., sharing and helping). In addition, participants mentioned physical aggression more often among their female peers than among their male peers. This study reveals the importance of context in understanding children's social behaviors. It is concluded that the present results have important implications for the school bus context and for future research on children's social interactions.
