    Study Notes

    Adolescent Brain Development

    • Frontal cortex undergoes significant structural changes during adolescence, with continued white matter growth and gray matter pruning.
    • By late adolescence, cognitive processing becomes more efficient due to fewer but stronger neuronal connections.

    Cognitive Development

    • Adolescents display mature bodies and can engage in abstract reasoning and sophisticated moral judgments.
    • Piaget's Stage of Formal Operations, around age 11, allows flexible manipulation of information, understanding of complex concepts, and symbolic representation.
    • Hypothetical-Deductive Reasoning emerges, enabling systematic hypothesis testing in problem-solving.

    Moral Development

    • Kohlberg's theory identifies three levels of moral reasoning:
      • Level II: Conventional morality focuses on social conformity and pleasing authority figures, typically reached after age 10.
      • Level III: Postconventional morality emphasizes autonomous judgments based on fairness and justice, usually developing in early adolescence or young adulthood.

    Role of Environment in Development

    • Schooling and culture contribute to cognitive and moral development, with evidence that educational exposure enhances reasoning abilities across different cultures.
    • Emotional and social networks in the brain are more susceptible to hormonal influences during puberty, particularly in early maturers, leading to increased risk-taking behavior.

    Impact of Puberty Timing

    • Early maturing adolescents, especially girls, face greater emotional stress and declines in academic performance.
    • Long-term studies show early-maturing girls experience ongoing depression and interpersonal difficulties, while boys generally adjust better.

    Identity Formation

    • Erikson identifies identity formation as a crucial task in adolescence, often accompanied by exploration and temporary distress.
    • Current views regard identity development as a gradual exploration rather than a crisis, leading to commitment in values and goals.

    Self-Concept and Self-Esteem

    • Adolescents enhance self-evaluation, with significant dimensions including peer relationships, physical appearance, and athletic abilities.
    • Achieved identity correlates with higher self-esteem and advanced moral reasoning; while foreclosure and diffusion indicate maladaptive identity processes.

    Peer Relationships

    • Family relationships provide emotional security, impacting the adolescent's confidence to explore identity and values.
    • Close friendships act as a support system for identity development, while diverse peer interactions foster value exploration.
    • Cultural influences shape identity construction, with variations in self-conception and continuity across life stages, as demonstrated by Native Canadian youths' narratives.
