Typical Cognitive Changes During Adolescence

During adolescence (between 12 and 18 years of age), the developing teenager gains the ability to think systematically about all logical relationships within a problem. The transition from concrete thinking to formal logical operations happens over time. Every adolescent progresses at their own rate in developing their ability to think in more complex ways. Each adolescent develops their own view of the world. Some adolescents may be able to apply logical operations to school work before they are able to apply them to personal problems. When emotional issues come up, they can add an additional level of complexity for an adolescent's cognitive reasoning. The ability to consider possibilities, emotions, and facts may impact decision-making in positive or negative ways.

Some common features indicating growth from more simple to more complex cognitive development include:

Early Adolescence

During early adolescence, the use of more complex thinking is focused on personal decision-making in school and home environments. This can include:

• Begins to demonstrate use of formal logical operations in schoolwork.
• Begins to question authority and society standards.
• Begins to form and verbalize their own thoughts and views on a variety of topics. These are usually more related to their own life, such as:
• Which sports are better to play
• Which groups are better to be included in
• What personal looks are desirable or attractive
• What parental rules should be changed

Middle Adolescence

The focus of middle adolescence often includes more philosophical and futuristic concerns. Examples may include:

• Often questions and analyzes more extensively
• Thinks about and begins to form their own code of ethics (what do I think is right?)
• Thinks about different possibilities and begins to develop own identity (who am I?)
• Thinks about and begins to consider possible future goals (what do I want?)
• Thinks about and begins to make their own plans
• Begins to think long term
• Begins to consider how to influence relationships with others
