Behavioural approach and behavioural inhibition as well as sensation seeking have been postulated important determinants of impulsive and risky decision making, or, the pursuit of long-term goals. Adolescence has been described a particularly sensitive developmental period, as an imbalance of these factors may result in risk-taking and counter-productive behaviour. In the current study, we assessed sensitivity to reward, sensitivity to punishment, and sensation-seeking in a cross-sectional sample of adolescents at secondary schools. The battery also included experimental paradigms to assess different forms delay and probability discounting, risk-taking behaviour and gambling as well as a capacity measure of intelligence. As outcome variables, we assessed counter-productive behaviour, substance consumption, and scholastic achievement. The presentation will focus on an imbalance of motivational approach and avoidance tendencies as predictors of risk-taking behaviour and will end with a brief discussion of the behavioural paradigms.
