Brain Development and Implications for Adolescent Risk Behaviors
a) The two topicsyou found most interesting from the documentary
The two topics that seemed most engaging to me in ‘Inside the Teenage Brain’ are the
decision-making power of the prefrontal cortex and how sleep plays a role in learning among
teenagers. The centre responsible for high-level decision-making and other extravaganza
activities in the brain is one of the last to develop fully. This is a comprehensive
developmental timeline that illustrates why teenagers are often impulsive in their decisions
and lack planning skills. This can help in understanding why teenagers are likely to make
certain illogical decisions and also help in formulating coping strategies for managing the
teenager. In this context, the documentary points that sleep is an essential factor influencing
the overall capacity of the teenage brain (PBS Presents, 2024). Teenagers require more sleep
than children, and for one reason or another, they lack sufficient sleep since they go to school
early and due to peer pressure. Sleep can thus disrupt memory, attention, and decision-
making, and their deficiency may have a negative impact on the entire organism. This issue
shows that it is essential to ensure that school timetables are consistent with the best
biological sleep-wake patterns of teenagers, thus supporting their learning and affective
experience.
b) Discuss how adolescent brain development and cognitive skills influence
decision-making.
Cognitive and neurological changes affect the decision-making capability as part of
adolescent brain development. The prefrontal cortex, which is found to be responsible for
higher functions including planning, being able to make decisions, and controlling impulses,
is completely developed once the person is in their mid-20s (PBS Presents, 2024). Teenagers
are most often underdeveloped, and they tend to act on instinct, which means they rely most
on the amygdala, the 'emotional' part of the brain, and not the prefrontal cortex. For this
3
reason, adolescence become bereft of sense, and they are likely to make decisions based on
emotional appeal. Moreover, during adolescence, circuitry also matures, particularly pruning
and myelination of the synaptic connections, thereby enhancing circuit complexity and
equally contributing to the vulnerability to stress and heightened emotional responses.
Working memory and attention still need to develop fully, which can hinder adolescents'
rational thinking in terms of the penalty they will have to pay for committing wrongdoing.
Rest is also critical during this developmental phase. This is an important aspect given that
the majority of teenagers have poor sleep habits as it affects their brain functioning; they are
unable to concentrate, retain information or even make sound decisions. This means that
comprehension of these increased risks and challenge factors is crucial to parents, educators,
and policymakers for environmental solutions, which will be beneficial for adolescents'
healthy decisions.
