Modeling social rejection, physiological arousal, and peer influence on risky driving among adolescents and young adults

Peer passengers are a significant risk factor for young drivers to experience adverse driving outcomes. However, few studies have manipulated social evaluation contexts and individual susceptibilities to peer influence, such as physiological arousal, to measure effects on driving. The current study explored whether social evaluation affects driving outcomes and if the type of evaluation affects perception of peer norms. Young drivers (N = 75) were randomized to control, social acceptance, or social rejection conditions and observed risky or risk-averse driving norms. Results indicated that peer passengers and peer driving norms, regardless of the social-evaluative context, affected variability in driving outcomes, particularly in intersections. Physiological arousal and perceptions of social acceptance also predicted more variability in driving outcomes. These findings suggest that passengers increase irregular driving patterns, perhaps due to passengers distracting young drivers from road conditions. Further, social acceptance increases the strength of the relationship between the presence of peer passengers and inconsistent driving patterns, indicating that social rewards may precede risky behavior more often than social threats do.
