Self-Regulation and Decision Making
Adolescence involves a complex interplay of biological, cognitive, emotional, and psychosocial changes when normative transitions in self-regulation, reward sensitivity, and decision making occur. As behavioral and cognitive systems mature at differing rates in adolescence, teens may be more vulnerable to the emergence of emotional and behavioral problems in the context of greater autonomy, independence, and responsibility. Youth develop more complex association networks pertaining to alcohol and other drug use across childhood and adolescence in concert with the development of more nuanced decision-making capabilities. As such, self-regulation of alcohol and other drug use behaviors may be particularly challenging for teens. In this chapter, we review the literature on the growth of self-regulation and decision-making abilities, their influence on the initiation and maintenance of alcohol and drug use in adolescence, and potential implications for prevention and intervention.
