Structural and functional brain development is thought to lead to different developmental progressions of cognitive control, risk/reward processing, and social cognition during adolescence. We compared these abilities in a cross-sectional sample of 90 adolescents aged 12, 15, or 17 years old, using computerized measures of inhibitory control (Go/No-Go task), risk-taking (Balloon Analogue Risk task), and social perspective-taking (Director task). Fifteen-year-olds exhibited better inhibitory control than 12-year-olds, while 17-year-olds exhibited greater perspective-taking than younger adolescents. Risk-taking was greater in older adolescents than 12-year-olds when controlling for inhibitory control. These findings are consistent with earlier findings obtained in separate samples.
