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.
