Adolescence Study Notes (Parts 1–11) Chapter 4B

Adolescence (part 1)

  • Transition from childhood to adulthood (puberty to independence).

  • Puberty: Period of sexual maturation, enabling reproduction.

  • Physical changes follow a predictable sequence, timing varies by individual.

Adolescence (part 2)

  • The teenage brain

    • Brain connections increase until puberty, then unused ones are pruned.

    • Myelin continues to develop, leading to improved cognitive function.

    • Hormonal surges and developing limbic system contribute to impulsivity, risky behavior, and strong emotions.

  • Legal Rulings

    • 2004: Death penalty ruled out for 16-17 year olds.

    • 2012: Life without parole ruled out for juveniles.

Adolescence (part 3)

  • David Elkind (1967) described adolescent egocentrism, where youth view the world through a unique lens:

    • The Imaginary Audience: Belief that everyone is constantly observing them.

    • The Illusion of Invulnerability: Feeling immune to misfortune.

    • The Personal Fable: Belief that their experiences and feelings are unique.

Adolescence (part 4)

  • Developing reasoning power (Piaget)

    • Formal operations allow for abstract and hypothetical thinking.

    • This includes deducting consequences and detecting inconsistencies/hypocrisy.

Adolescence (part 5)

  • Developing morality (Piaget; Kohlberg)

    • Moral reasoning guides moral actions; moral people think and act ethically.

    • A newer view suggests much moral functioning is unconscious/automatic.

    • Critical tasks: Discerning right from wrong, developing character, empathizing with others.

Adolescence (part 6)

  • Moral reasoning (Kohlberg)

    • Studied moral dilemmas to establish a hierarchy of reasoning.

    • Proposed three invariant levels of moral thinking: preconventional, conventional, and postconventional.

    • Critics noted cultural limitations of the postconventional stage and gender bias.

Adolescence (part 7)

  • Kohlberg’s Levels of Moral Thinking (Example: Is it okay to steal medicine to save a loved one?)

    • Preconventional morality (before age 9)

    • Focus: Self-interest; obey rules to avoid punishment or gain rewards.

    • Example: “If you save your loved one, you’ll be a hero.”

    • Conventional morality (early adolescence)

    • Focus: Uphold laws/rules for social approval or to maintain social order.

    • Example: “If you steal the medicine, everyone will think you’re a criminal.”

    • Postconventional morality (adolescence and beyond)

    • Focus: Actions reflect belief in basic rights and self-defined ethical principles.

    • Example: “People have a right to live.”

Adolescence – Identity Development

  • Erikson's concept of ego identity focuses on self-definition and purpose.

  • The central challenge is identity versus identity (role) confusion.

  • Choices and experiences shape one's sense of self, which is continuously revised.

  • Erikson highlighted social contexts' role in personality development.

Erikson’s Psychosocial Stages of Development

  • Erikson's theory spans the entire lifespan; adolescence focuses on identity formation within social contexts.

James Marcia (part 10)

  • Two processes (exploration and commitment) lead to four identity statuses:

    • Identity diffusion: No exploration or commitment.

    • Foreclosure: Commitment made without exploration.

    • Moratorium: Active exploration, but no commitment yet (seen by Erikson as key to adolescent mind).

    • Identity achievement: Exploration followed by commitment.

  • Individuals can be in different statuses for different aspects of identity (e.g., religion, career).

Adolescence (part 11) – Parent and peer relationships

  • Parental influence decreases, peer influence increases.

  • Influenced by existing attachments and perceptions.

  • Selection effect: Adolescents often choose friends who are similar to themselves.

  • Parent-child arguments are common but can lead to positive relations through networking (of family).
