The different centres of the brain develop and become functionally connected over time. The brain reaches 90% of its adult size by the time a person is six or seven years of age. The learning environment plays a significant role in brain development. I think the area of adolescent brain development is one of the areas in cognitive neuroscience where actually brain imaging has completely revolutionized what we know. Using longitudinal neuroimaging techniques, the lab examines developmental trajectories over time in the domains of self-development and self-regulation, social learning and prosocial behavior, as well as the predictors of contribution to society. 73 0 obj <>/Filter/FlateDecode/ID[<8D7465F4002011D3062402599D85E9DA><90D934B10142154CA084BC0DBC696748>]/Index[68 12]/Info 67 0 R/Length 49/Prev 53261/Root 69 0 R/Size 80/Type/XRef/W[1 2 1]>>stream This volume offers a range of empirical and theoretical perspectives on the relationship between biology and social cognition from infancy through childhood.

Biological changes in brain structure and connectivity in the brain interact with increased experience, knowledge, and changing social demands to produce rapid cognitive growth. The development of the prefrontal cortex has a huge impact on adolescent brain development and decision making. Although increases in white matter continue through adolescence into adulthood, particularly in frontal brain regions, the most rapid changes occur during the first 2 years. The difference in timing of the development of these different regions of the brain contributes to more risk taking during middle adolescence because adolescents are motivated to seek thrills that sometimes come from risky behavior, such as reckless driving, smoking, or drinking, and have not yet developed the cognitive control to resist impulses or focus equally on the potential risks (Steinberg, 2008).
