Five Dev. Tasks of Adolescence
- Accept full-grown body and changes of puberty
- Acquire adult ways of thinking
- Develop more mature ways of relating to peers of both sexes - less gender segregation
- Consolidate an identity - developing a secure sense of who you are
- Attain greater independence from the family
puberty def
the set of biological processes that change the immature child into a sexually mature person → sexual maturity to reproduce
puberty timing
GIRLS = 10-15 y.o. BOYS = 11.5-17 y.o.
growth spurt for each sex
- GIRLS = start spurt earlier, often age 10. Lasts about 2.5 years. Often grows 8-10 inches in height.
- Boys start spurt later, around age 12.5, and grow for a longer period of time, so they may add 12-13 in. of height
major changes in overall body growth
• Reverse of cephalocaudal trend - the feet and legs often grow first, then the torso
• Increase in appetite
• Increase in size & activity of oil-producing glands - causing acne, and sweat glands=body odor
o Girls add more fat than boys - often in arms and legs
o Boys gain more muscle strength than girls
primary vs. secondary sexual characteristics
PRIMARY : involve reproductive organs directly
SECONDARY : external physical changes that help distinguish M & F (breasts, facial hair)
general changes
- Increases in levels of androgens and estrogens for girls and boys, but levels are sex-specific
- Boys get more androgens like testosterone → leads to muscle growth, gains in body size, sex characteristics
- Girls get more estrogens - cause breasts, uterus, and vagina to mature, fat to accumulate, regulate menstrual cycle
menarche
(first menstruation) - occurs late in sequence, typically around age 12.5 (can be 9.5-16.5 and around ~100 lbs. for it to kick in)
spermarche
is the beginning of development of sperm in boys’ testicles at puberty. It is the counterpart of menarche in girls.
roles of genes - puberty timing
• Tend to reach puberty at about the age our parents did
TWIN STUDIES = identical - 2 months diff., frat were 12 months diff.
environment - puberty timing
o Nutrition, weight, dieting, exercise
o Psychosocial aspects
socioemotional stress - puberty timing
- links between earlier pubertal timing & stress: divorce, father absence, family conflict
- EVOLUTIONARY MODEL = in a stressful home environment, it is adaptive to mature early, reproduce early
effects of early and late maturation
o Early maturing: boys tend to fare better than girls
• Early maturing boys → helpful for sports and athletics
• Late maturing boys→ later than everybody else and don’t do as well psychologically
o Later maturing: girls fare better than boys
• Early maturing girls → feel more self-conscious and different from their peers
why body image is a focal concern
- Amazing amount of growth
- Yet adolescents are now aware of changing body
- Adolescents as marginal group - a group between cultures – within-group conformity is important
Jones et. al ***
• Mass media contribute by presenting one-dimensional images of attractiveness
o Girls - curvy, thin, sexy, attractive face
o Boys - lean, muscular, attractive face
eating disorders
• Increased risk of eating disorders, such as anorexia and steroid abuse in boys
*Girls that are at higher risk = those that reach puberty early, dissatisfied with their body image, and grow up in homes where concern with weight and thinness
general nature of dating
• Ages: Start dating at 13-14 (girls) & 14-15 (boys)
in groups
• For many, early dating is based on a superficial intimacy rather than a genuine closeness
early sexual experiences
During ages 15-19, a majority become sexually active
BOYS = scoring
GIRLS = emotional love and intimacy
STIS
• Adolescents have highest STI rate of all age groups - 1 in 5-6 sexually active teens contracts one each year
gender differences in sexual scripts
MALES • Expected to be interested in sex; part of being a man
• Expected to take the initiative
• Expected to focus on women’s appearance
• Acceptance/idealization of nonrelational sex
FEMALES • Expected to be less interested in sex, more interested in love and relationships (“good girl” vs. “bad girl”)
• Responsible ones and limit-setters
• Little emphasis on own desire; goal is to be desirable
sexual socialization as a multidimensional process;
- Learning involves many issues
- Input comes in different forms
- Input is received across the lifespan
- Information comes from several sources
common sources of sexual communication
- Parents seen as initially sexuality educators
- Peers, schools, media often cited as most important
- Source of information varies by topic
nature of parental sexual communication
- American parents typically give minimal direct, verbal information
- Focus of communication is often on biology, physical development, sexual safety
- Minimal discussion of sexual pleasure, sexual feelings
- impact of parental communication on early sexual behavior
- Some studies find that parent/child communication is associated with a delay of sexual intercourse & safer sex practices
- A handful report the opposite association
- Many others report no effects
