chap 13 & 14 Flashcards
what is senescence?
natural aging that everyone experiences after body structures hit their peak
what factors impact senescence?
environment, time period, DNA, and how they care for their bodies
what are three theories of aging?
1) programmed effects of specific genes (hayflick limit-telomeres)
2) cumulative effects of random events (free radicals)
3) cross-linkage theory of aging
what is the theory of programming effects of aging genes?
we inherit “aging genes” that determine the changes we experience as we age. over time, our telomeres shorten and then can’t duplicate again, which leaves us vulnerable to diseases, decreased functioning, and earlier death
what is the theory of cumulative effects of random events?
DNA is damaged through spontaneous or externally-caused mutations. researchers have hypothesized that this is due to free radicals, highly reactive chemicals that form in the presence of oxygen. when oxygen is broken down, free radical looks for a replacement and destroys nearby cellular material
what have recent studies found about free radical damage and aging?
not necessarily correlated, but free radical damage may increase longevity
what is the cross-linkage theory of aging?
protein fibers form the body’s connective tissues link to each other. when fibers thag are meant to be separate cross-link, it leads to less elastic tissue and many negative outcomes. this cross-linkage can be reduced through living a healthy lifestyle, physical activity and nutritious diet
when do many athletic skills peak?
20-35
what specific athletic tasks peak in early 20’s?
tasks that require limb movement, explosiveness, gross-motor skills like sprinting, jumping, and tennis
what tasks peak in late 20’s and early 30’s?
endurance, arm-hand steadiness, aiming like long-distance running, baseball, golf
why do tasks that peak in late 20’s and early 30’s take longer to perfect?
require stamina and precision
what are lower levels of performance in healthy people attributed to?
body’s adaptation to a less physically demanding life - reduced capacities because they are not used as much anymore
what is dualistic thinking?
separating information, beliefs, and authority into right and wrong, good and bad, and us and them
what is relativistic thinking?
no absolute truth, everything is a matter of opinion.
“what’s true for you is true for you, and what’s true for me is true for me”
what is commitment within relativistic thinking?
the focus is on finding a personally fulfilling view rather than choosing between opposing views. find logical criteria to measure things against and accept new evidence or ideas when they are presented
what is cognitive-affective complexity?
being aware of conflicting positive and negative feelings and bringing them together to form a complete and unique individual experience.
what are the 3 periods in selecting a vocation?
1) fantasy period
2) tentative period
3) realistic period
fantasy period?
children in early-middle childhood fantasize about future career options, but they are usually glamorized
tentative period?
between 11-16 years old, adolescents start to think more complexly about career options. consider them according to their interests, abilities, and values
realistic period?
in late teens and early twenties, people narrow down their options. they go through 2 phases, exploration where they find more info about options that will work well with their personality and crystallization where they focus on a general area, experiment, and eventually settle on an occupation
what is emerging adulthood?
transitional period between teenage years and taking on of adult roles
who culturally is most likely to experience emerging adulthood?
high SES and higher education.
cultures that delay entry into adult roles until they reach their 20’s. happens to privileged minority in developed countries and those in industrialized countries because their families can provide financially while they explore and seek higher ed.
what is erikson’s crisis in early adulthood?
intimacy vs. isolation
what is intimacy vs. isolation?
psychological conflict of early adulthood, seen in YA’s thoughts and feelings about

how does identity achievement impact intimacy?
identity achievement, having a secure sense of self, increases loyalty and love in intimacy. more ready for relationships and more committed relationships

exploration without commitment, negatively impacts intimacy. less loyalty and less love
what is the social clock?
society’s idea of the “right” age to reach milestones
how do other-sex friendships change after marriage?
