There are major changes in cognition from childhood into adolescence. These changes highly contribute to the decision making process during adolescence. Steinberg (2013) explains five ways in which adolescents become sophisticated in their thinking abilities when compared to children. Secondary to the biological development of the brain, adolescents are able to think about possibilities, rationalize abstract concepts, engage in metacognition, think in multiple dimensions and see knowledge as relative. The development of the prefrontal cortex during adolescence permits them to engage in sophisticated thinking. For example, they are able to compare different possibilities, they are able to monitor their own thought processes and comprehend abstract logic. Therefore, when it comes to making decisions, adolescents are able to value possibilities and consequences better than a child, but still not like an adult. Despite of the improvements in decision-making and cognition, adolescents are still driven towards risk-involving activities. As per Steinberg (2013), this could be explained by the time gap between the development of the limbic system in puberty and the prefrontal cortex maturing years after. However, the changes that occur in the brain during adolescence are not necessarily at fault for adolescent behavior. “It is important to keep in mind that evidence of a correlation between the changes in brain structure or function changes in adolescent behavior does not necessarily mean that the first is necessarily causing the second” (Steinberg, 2013, p. 71). The environment and the life events adolescents experience play a major role in the behavior they choose to engage in. The more adolescents engage in risky behavior, the stronger the connections between the neurons, active during this behavior, become; therefore, making the behavior easier to perform.
