Abstract
|
|
|
|
Adolescence is a period of physical, cognitive, and social development between childhood and adulthood. Neuroimaging studies indicate that dynamic changes, both structural and functional, occur in the adolescent brain. Such adolescence-associated alterations in the brain likely promote the development of the cognitive competencies and social relationships necessary for effective adult functioning. The thesis of this review is that developmental changes in the brain contribute to the age-specific cognitive and behavioral characteristics of adolescence. Based on findings from neuroscience, we describe pubertal hormone changes at the beginning of adolescence, the activation-organization theory of brain development, cognitive development, risk-taking behavior and social behavior during adolescence. We also discuss how pubertal hormones alter brain function and, thereby, cognition and behavior.
