Study Notes
Puberty and Family Influence
- Family conflict, harsh parenting, and parental separation are linked to early puberty timing in girls and, to a lesser extent, in boys.
- Warm, stable family environments tend to correlate with later onset of puberty.
- Adverse childhood experiences influence adolescent sexual risk-taking, particularly in girls, confirmed by longitudinal studies.
Key Concepts in Puberty
- Spermarche: The first ejaculation for boys.
- Menarche: The first menstruation for girls.
- Secular Trend: A generational trend indicating earlier attainment of adult height and sexual maturity, observed over the last century in some countries.
The Adolescent Brain Development
- Contrary to past beliefs, the adolescent brain continues developing through puberty into young adulthood.
- Changes in structures related to emotions, judgment, and self-control are prominent during this stage.
- Legal implications arise from brain immaturity, notably regarding the treatment of juvenile offenders.
- Two primary brain networks engage in risk-taking behaviors:
- Socioemotional network: More active during puberty, sensitive to social influences.
- Cognitive-control network: Matures more gradually, regulating impulse responses.
Cognitive Development in Adolescence
- Adolescents can think abstractly, manipulate information flexibly, and appreciate metaphor and allegory.
- Improved attention and inhibition skills enhance reasoning and information processing.
- Metacognition: Awareness of thought increases, leading to better strategies for information acquisition and problem-solving.
Piaget’s Formal Operations
- Formal operations emerge around age 11, facilitating abstract thought and sophisticated reasoning.
- Adolescents engage in propositional thought, evaluating the logic of statements regardless of real-life circumstances.
Erikson's Psychosocial Development
- Identity formation is crucial during adolescence, involving self-definition and direction.
- Adolescents often experience an identity crisis as they explore and commit to values, leading to a mature identity.
- Successful psychosocial outcomes in early life facilitate positive identity resolution in adolescence.
Substance Use Trends Among Teenagers
- Teenage alcohol and drug use is prevalent in industrialized nations.
- Approximately 20% of U.S. tenth graders have tried smoking; 47% have consumed alcohol; and 37% have used illegal drugs.
- By high school graduation, 6% regularly smoke, 17% engage in heavy drinking, and 21% have used marijuana.
- Awareness and preventive efforts have led to a decline in overall substance use since the mid-1990s, despite a rise in marijuana use in recent years.
- Attraction to sensation-seeking and cultural factors contribute to adolescent substance use patterns, alongside media influences and parental behaviors.
