exam 4 Flashcards
at 16 what are you in
adolescences (11-18)
puberty
4 year process; physical maturation
become capable of reproduction
Onset:
- It begins in late childhood at about age 8 or 9 in girls and roughly two years later in boys
-both estrogen and testosterone is released for both
-girls have more negative effects from pubertal timing
Adolescent growth spurt
first outward sign of puberty (secondary)
-a rapid gain in height and weight that generally begins in girls at about age 10 (as early as age 7 and as late as 14) and in boys at about age 12( as early as age 9 and as late as 16)
-boys lungs and heart work better
Secondary sex characteristics
physical features that are visible outside of the body
-serve as signs of sexual maturity
-not directly related to fertility
menarche/spermache
first menstruation; first ejaculation (balls)
genetic theories of aging
same signs if aging as our parents
Delayed sleep preferences
triggered by change in nightly release of hormone melatonin
-onset of sleep takes place 2 hours later for adolescent after puberty
Limbic System
subcortical structure responsible for emotions that undergoes a burst of growth in response to pubertal hormones
amygdala
plays a role in fear learning, reward, aggression, and sexual behavior, increases in volume in childhood and peaks in growth at around 12 to 14 years of age
-boys have a greater rate of growth
prefrontal cortex
continues to develop in emerging adulthood, into the mid-20s
-seat of reasoning, cognitive control, decision making, and planning, suggesting that these sophisticated abilities continue to develop well into emerging adulthood.
dual system model
explains behavior of adolescents
-limbic system has burst before prefrontal
-risky behavior bc of this uneven
programmed senescence
a pattern of gradual age related declines in physical functioning
-cells have a limited capacity to reproduce
-hyflick limit (50 times)
wear and tear
old aging theories we do not use (cells and tissues have vital parts that “wear out”
-we use the “use it or loss it theory”
fertility and parenthood
average age of first birth has increase for US woman
-secular trend
-infertility: women failure to ovulate and ovarian cysts
men: sperm decrease by age 40
changes in infertitlity
-ability to conceive after 12 months
Formal Operations (Piaget)
the ability to think abstractly, logically and systematically
-reason about ideas, possibilities that don’t exists in reality
-age 11
imaginary audience
a manifestation of adolescent egocentrism in which they assume that they are the focus of others attention
-is experienced as self-consciousness
-ontributes to the heightened self-consciousness characteristic of adolescence
-decide to lie and not go to school bc of appearance
Personal Fable
a manifestation of adolescent egocentrism in which adolescents belive their thoughts, feelings, and experieces are more special and unique than anyone else and they are invulnerable
-may predispose adolescents to seek risks, leading them to believe that they are immune to the negative consequences
imaginary audience and personal fable
thought to increase in early adolescence, peak in midde, and decline in late, but research has showed that it may persist into late adolescence and beyond
Best outcomes for acedemic achievement
-schools match students developmental needs
-strong teach-student relationships
-schools foster a sense of school belonging and positive student conduct
-close parent adolescent relationships and authoritative
-peers with academic values
post-formal cognitive development
thinking and problem solving are restructured in adulthood to integrate abstarct reasoning with practical considerations
-rules to society
-dualistic: views are either right or wrong
-relativistic: dependent on thinker or situation, acknowledges beliefs are subjective and defensible
-reflective: most mature thinking, evaluates different views
(very few adults demonstrate reflective judgement)
cognitive-affective complexity
using emotions to solve problems
-a form of mature thinking that involves emotional awareness
-emotions play a part in reasoning
-adults better understand others, including their perspectives, feelings, and motivations, influencing their social relationships.
-most adults use this
first-generation students
they dont have family or anyone to tell them about their experiences
-tend to be less active in campus and extracurricular activities and less academically prepared
-more likely to feel guilty about their educational achievement
