Compared to children, adolescents think in ways that are more advanced, more efficient, and generally more complex.
This is evident in five distinct areas of cognition.
Second, during the passage into adolescence, individuals become better able to think about abstract ideas.
For example, adolescents find it easier than children to comprehend the sorts of higher-order, abstract logic inherent in puns, proverbs, metaphors, and analogies.
The adolescent's greater facility with abstract thinking also permits the application of advanced reasoning and logical processes to social and ideological matters.
This is clearly seen in the adolescent's increased facility and interest in thinking about interpersonal relationships, politics, philosophy, religion, and morality—topics that involve such abstract concepts as friendship, faith, democracy, fairness, and honesty.
There is no single event or boundary line that denotes the end of childhood or the beginning of adolescence.
Third, during adolescence individuals begin thinking more often about the process of thinking itself, or metacognition.
As a result, adolescents may display increased introspection and self-consciousness.
The biological transition of adolescence, or puberty, is perhaps the most observable sign that adolescence has begun.
Technically, puberty refers to the period during which an individual becomes capable of sexual reproduction.
