According to the dual systems model of adolescent risk taking, sensation seeking
and impulse control follow different developmental trajectories across adolescence and are
governed by two different brain systems. The authors tested whether different underlying
processes also drive age differences in reward approach and cost avoidance. Using a
modified Iowa Gambling Task in a multinational, cross-sectional sample of 3,234
adolescents (ages 9–17; M= 12.87, SD= 2.36), pubertal maturation, but not age, predicted
reward approach, mediated through higher sensation seeking. In contrast, age, but not
pubertal maturation, predicted increased cost avoidance, mediated through greater impulse
control. These findings add to evidence that adolescent behavior is best understood as the
product of two interacting, but independently developing, brain systems.
