  • Peers are often more important than parents in terms of attachment and influence.
  • The adolescent is capable of reasoning in abstractions for the first time.

Socioemotional Development:

  • Erikson’s Theory and Identity Development – Indentity vs. Identity Confusion (5th stage). Erikson viewed the developmental  changes occurring throughout life as a series of eight stages of psychosocial development.

According to Erikson’s theory:

  • The outcome of turning points or “crises” will partly determine the course of future personality development.
  • Each stage represents a pairing of the most positive and negative aspects of the crisis of that period.

Marcia’s Theory of Identity Status:

James Marcia suggested that there are four identity statuses, or stages, in developing who we are as individuals. These stages are achievement, moratorium, foreclosure, and diffusion.

  • Exploration of options for career and personal values
  • Commitment to, and investment in, an identity path

MARCIA

Kohlberg developed his Theory of Moral Development by presenting boys with moral dilemmas and asking them to evaluate the situation and people involved.

Kohlberg’s Three Levels of Moral Development

1)Premoral Level: Children do not understand morality as a normal adult, and instead make moral judgments based on obtaining rewards or avoiding punishments.

2) Conventional Level: Children begin to make moral decisions based on what they think others will think of them, especially their parents’ ideas of societal rules.

3) Principled Level: Actions are judged on the basis of ethical principles rather than personal consequences.

KOHLBERG
