Research indicates that the prefrontal cortex, a part of the brain deeply involved in assessing risks and making complex judgments, is still developing during the adolescent years. Given that, should adolescents have the same rights and be held to the same standards of responsibility as adults? For example, should they be able to consent to sexual activity or join the armed forces? If they commit an offense, should they be tried as adults?
Another important time during our lives when the prefrontal cortex “turns off” a bit is during REM sleep. Consider the role of REM sleep and dreams in your life. Does this “turning off” of the prefrontal cortex substantiate or repudiate Freud’s theory? Frame your response in the language of the course with special attention to current, relevant peer-reviewed research.
In regards to risk taking/complex judgments:
- A period in which adolescents are given a degree of freedom to explore their impulses, talents, interests, social roles, and beliefs without fear that minor offenses against convention will bring drastic consequences.
- Examining alternatives in a particular area of activity, such as occupation or beliefs and values.
- Acting in ways that are guaranteed to arouse disapproval, but that also guarantee attention and concern.

The Development of decision-making capacities in adolescents.pdf
This article reviews current research on the development of decision making capabilities of adolescents who are defendants. The article also discusses sociological, psychological, and neurobiological research that factor into adolescent decision making. It also discusses the trend for more severe punishments for juvenile defenders.

~"Neuroscientists have found evidence that the pleasure center in the limbic system develops more quickly during adolescence than the impulse control systems in the prefrontal cortex. This discrepancy may help explain the fact that teens who should--and generally do--know better take risks that endanger their health, their happiness, and even their lives" (McMahan, 2009, p.92)
