Neural systems underlying reward and approach behaviors in childhood and adolescence.

Transitions into and out of adolescence are critical developmental periods of reward-seeking and approach behaviors. Converging evidence suggests that intriguing reward-related behavioral shifts are mediated by developmental changes in frontostriatal circuitry. This chapter explores how the conceptual frameworks and empirical studies in the field of developmental cognitive neuroscience have contributed to understanding reward-related behavior across development.The chapter concludes with some implications for adaptive and maladaptive behaviors that arise from these behaviors as children transition from childhood to adolescence.
