Amygdala vs. Prefrontal Cortex

The amygdala, responsible for emotions, develops faster than the prefrontal cortex, which controls judgment and impulse control, leading to intense emotions and difficulty regulating them.

Study Notes

Identity vs. Identity Confusion

  • Identity: Refers to values, goals, beliefs, attitudes, behaviors, lifestyle, occupation/career path, and sexual identity
  • Development: Builds upon previous stages (trust, autonomy, initiative, industry, fidelity)
  • Identity confusion: Allows for flexibility
  • Virtue: Fidelity
  • Significant Others (SSI): Friends

Physical Changes

  • Puberty: Rapid physical maturation, primarily in early adolescence, marked by hormonal and bodily changes
  • Sexual Maturation: Weight and height gains
  • Boys: Facial/chest hair growth, pubic hair
  • Girls: Breast growth, menarche (first menstruation)
  • Hormonal Changes: Increased testosterone and estradiol, chemicals secreted by endocrine glands
  • Timing Variations:
  • Average age of menarche has decreased since the mid-19th century, potentially due to better nutrition/health, low socioeconomic status, urban living, and family problems
  • Stress can also be a factor
  • Pubertal sequence:
  • Boys: 10-13 ½ years
  • Girls: 9-15 years
  • Body Image:
  • Common preoccupation throughout adolescence
  • Girls often have lower body image satisfaction and more negative perceptions
  • Satisfaction improves in late adolescence
  • Comparison: Girls experience lower body image satisfaction compared to boys
  • Early vs. Late Maturation:
  • Boys:
  • Early: Higher self-esteem and better peer relations initially
  • Late: Stronger sense of identity in 30s (more exploration time)
  • Girls:
  • Early: Greater satisfaction initially but less later, more likely to smoke/drink/have earlier sexual encounters, develop eating disorders or other psych disorders, earlier independence, older friends.

The Brain

  • Amygdala/Limbic System: Develops faster than the prefrontal cortex, involved in emotions
  • Corpus Callosum: Thickens in adolescence, connecting brain hemispheres for more efficient processing
  • Prefrontal Cortex: "Judgment" region, responsible for controlling intense emotions; doesn't fully develop until emerging adulthood
  • Limbic System: Seat of emotions and experience of rewards, almost completely developed in early adolescence
  • Other Changes: Increase in dopamine, related to increased risk-taking and reward-seeking

Adolescent Sexuality

  • Sexual Identity: Exploration, experimentation, vulnerability, and confusion during adolescence
  • Develops from asexual to sexual
  • Dimensions: Activity, interests and styles of behavior, and behaviors.
  • Timing of Sexual Behaviors:
  • Lower socioeconomic status adolescents tend to engage in sexual activity earlier
  • Filipinos may demonstrate lower activity than Americans, with potential differences in timing and impact of socioeconomic status
  • Risk Factors:
  • Drug use, delinquency, school problems
  • Socioeconomic status
  • Family factors (parental knowledge, rules, disagreements, conflict, sexually active siblings)
  • Peer influence (deviant peers, connectedness to school, academic factors, religion)

Adolescent Health Issues

  • Sleep Patterns:
  • Only 31% of US adolescents sleep 8+ hours nightly
  • Sacrificing sleep negatively impacts comprehension and class performance
  • Related to psychological disorders
  • Potential causes: Media, caffeine, brain changes (later melatonin release), early school starts
  • Eating Disorders:
  • Anorexia Nervosa: Relentless pursuit of thinness through starvation, weight less than 85% of normal for age/height, intense fear of weight gain, distorted body image.
