Which developmental stage possesses a fairly mature level of reasoning?

The developmental stage of adolescents, which spans from approximately 13 to 18 years, is characterized by a fairly mature level of reasoning. During this period, adolescents experience significant cognitive development, leading to improvements in abstract thinking, problem-solving skills, and the ability to consider multiple perspectives. They begin to think more critically and reflectively, enabling them to understand complex concepts and engage in more sophisticated forms of reasoning.

This stage is influenced by ongoing changes in the brain, particularly in areas responsible for decision-making and impulse control, which further refine their reasoning abilities. Adolescents also start to develop a stronger sense of identity and an understanding of social relationships, which can enhance their capacity for empathy and moral reasoning. Thus, the cognitive advancements that occur during adolescence position individuals in this age group to possess a level of reasoning that is considerably more developed than that seen in younger children.
