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.
