The National Juvenile Justice Network recently published new research exploring the significant differences in teens’ brains compared to adults’. The latest research, “Using Adolescent Brain Research to Inform Policy: A Guide for Juvenile Justice Advocates,” looks at specific areas of the brain and how they function when involved in particular activities and thinking. This has allowed researchers to learn a great deal about how teens and adults differ when using their brains.
Major findings from the report include:
- Brain development takes place in stages and is not fully complete in adolescence. The frontal lobe, tasked with decision making, planning, judgement, expression of emotions and impulse control may not be fully mature until the mid-20s.
- The limbic system, which helps to process and manage emotion, is also developing during adolescence. This causes adolescents to experience more mood swings and impulsive behavior than adults.
- Levels of dopamine production shift during adolescence. As a result, activities that once were exciting to youth may not be so as they enter adolescence, and thus they may seek excitement through increasingly risky behavior.
- When adolescents make choices involving risk, they do not engage the higher-thinking, decision-and reward areas of the brain as much as adults do. This can lead adolescents to actually overstate rewards without fully evaluating the long-term consequences or risks involved in a situation.
This new research can be useful in beginning conversations about evidence-based practices when considering how to change the juvenile justice system for the better. Via the report, “Brain development research provides heretofore reluctant legislators from “tough-on-crime” districts a basis for a shift from punishment of juveniles to rehabilitation.” The full report is available as a PDF online (download link), and includes further details about the findings and recommendations about how they can be applied to enhance positive youth development.
