Final answer:
The increase in impulsivity during adolescence is linked to the development of the prefrontal cortex, responsible for executive functions such as impulse control, which is not fully matured until early adulthood.
Step-by-step explanation:
Brain development in adolescence is associated with increased impulsivity, particularly due to the ongoing maturation of the prefrontal cortex. This is the correct answer to the student's multiple-choice question:
Brain development in adolescence is associated with increased impulsivity, and the prefrontal cortex is primarily involved.
The prefrontal cortex is the area responsible for judgment, impulse control, and planning. This region continues to develop into early adulthood and is associated with executive functions such as decision-making, risk evaluation, and impulse control. During adolescence, the brain undergoes significant changes, including increased folding of the cerebral cortex, synaptic pruning, and myelination, leading to cognitive advances. As this area of the brain is still developing during adolescence, it is common for teenagers to exhibit more impulsive behavior. The limbic system, which is also maturing during this time, plays a role in emotional responses and reinforces behavior through pleasure and reward.
In adolescence, brain development is related to adolescent impulsivity. The prefrontal cortex, which is involved in judgment, impulse control, and planning, is primarily involved in adolescent behavior.
