Lecture 20: Adolescence 1 Flashcards
What is adolescence, and what are its key tasks?
- Adolescence (WHO): A transitional phase from childhood to maturity, ages 10–19 years.
Key Tasks:
Adjust to physical changes.
Develop sexual identity.
Adapt to new cognitive abilities.
Strive for emotional maturity and independence.
How has the age of puberty changed historically?
- Age of menarche has decreased significantly (e.g., Norway: 17 years in 1840 to 13 years today).
Study: Santrock (1998):
Causes: Improved nutrition, health, heredity, and increased body mass.
What are the key physical changes during puberty?
- Growth spurt: 10 inches in height and 40 pounds in weight.
- Hormonal changes: Increased testosterone and estradiol.
- Estradiol is critical for menstruation.
Methodology: Longitudinal studies of adolescent growth trajectories.
How does puberty affect body image?
- Adolescents are least satisfied with their bodies during puberty.
- Girls report greater dissatisfaction than boys.
Study: Wright (1989); Brooks-Gunn & Paikoff (1993):
Methodology: Surveys of adolescents measuring self-perception of body image.
How does puberty influence mood changes?
- Hormonal changes cause:
Boys: Anger and irritability.
Girls: Anger and depression.
Study: Brooks-Gunn & Warren (1989):
Methodology: Longitudinal study linking hormonal fluctuations to emotional changes.
What are the hypotheses about the timing of puberty?
- Stressful Change Hypothesis: Rapid changes cause stress (Simmons & Blyth, 1987).
- Off-Time Hypothesis: Early/late puberty causes additional distress (Livson & Peskin, 1980).
- Early-Timing Hypothesis: Early maturation leads to inappropriate maturity demands (Stattin & Magnusson, 1990).
How does early puberty affect girls?
- Early-maturing girls experience higher levels of behavioral problems, including aggression and anxiety.
Study: Caspi & Moffitt (1991):
Participants: 348 New Zealand girls.
Methodology: Behavioral problem scales measuring aggression, motor tension, and attention issues.
How does early and late puberty affect boys?
- Early-maturing boys: Gain self-esteem, popularity, and leadership but may become rule-bound.
- Late-maturing boys: Are more dependent, insecure, and rebellious.
Studies: Alsaker (1992); Petersen (1993): Longitudinal surveys assessing boys’ social and psychological outcomes.
What is the relationship between puberty and depression?
- Depression rates increase significantly for girls during adolescence, doubling the rate for boys by age 13.
Study: Stumper & Alloy (2021):
Methodology: Review of 36 studies linking advanced pubertal stage to depression risks.
How does parenting influence adolescent mental health?
- Parental warmth, behavioral control, and autonomy reduce depression.
- Psychological and harsh control increase anxiety and depression.
Study: Gorostiaga et al. (2019):
Methodology: Meta-analysis of 59 studies across ~30 countries.
What did Larson et al. (1996) find about time spent with family during adolescence?
- Family time decreases, but one-on-one time with parents remains stable.
Methodology:
Participants recorded activities and emotions 7–8 times daily using pagers.
Sample: 220 middle-class adolescents (grades 5–12).
How does parental autonomy support affect adolescents?
- Parental autonomy fosters better emotional regulation and mental health outcomes.
Study: Youniss & Smollar (1985): Observational and survey-based studies on evolving parent-child relationships during adolescence.
What are the long-term implications of early puberty for girls?
- Increased risks for depression, anxiety, and social withdrawal.
Study: Stumper & Alloy (2021): Longitudinal tracking of hormonal changes and depressive symptoms.
How do gender differences manifest in depression during adolescence?
- Rates for girls increase due to hormonal shifts, body image concerns, and environmental stress.
Methodology: Cross-sectional and longitudinal studies tracking depressive symptoms and hormonal stages.
What are the key findings about adolescence and mental health?
- Puberty brings significant physical, psychological, and social challenges.
- Early puberty is linked to increased behavioral problems and mental health issues.
- Parenting styles play a critical role in adolescent well-being.
- Depression rates are higher in girls during adolescence due to biological and environmental factors.
