Exam 3 Flashcards
Define senescence
A gradual physical decline related to aging (when growth stops) (affects every part of the body, visible, invisible)
Define infertility
The inability to conceive a child after trying for at least a year
Why does infertility typically occur?
- Age (both)
- Male: Low sperm count-age, anything that impairs body functioning for over 75 days reduces sperm count, pollution, stress, STIs
- Female: anything that impairs body functioning, pelvic inflammatory disease, STIs,
What is ART?
Assisted reproductive technology- helps many couples overcome various fertility obstacles
What are ways to overcome infertility?
- surgery to repair male or female reproductive systems
- Assisted reproductive technology
-in vitro fertilization (iVF)- ova (egg cells) are surgically removed from a woman and fertilized with sperm in a laboratory, fertilized cells divide several time, then inserted into woman’s uterus
(May increase illness, birth defects, low birth weight, twins, triplets)
Define menopause
The time in middle age, usually around 50, when a woman’s menstrual periods cease and the production of estrogen, progesterone, and testosterone drops. Menopause is dated one year after a woman’s last menstrual period.
Define andropause
A term coined to signify a drop in testosterone levels in older men, which normally results in reduced sexual desire, erections, and muscle mass
If severe brain loss occurs before late adulthood, the cause is not normal senescence but one of the following
Drug abuse- all psychoactive drugs harm the brain, especially excessive alch use
Poor circulation-everything that impairs blood flow (high blood pressure, smoking) impairs cognition
Viruses- can destroy neurons
Genes- Alzheimer’s disease gene and other genes also affect the brain
What are changes in the brain with age?
- neurons fire more slowly
- messages sent from the axon of one neuron are not picked up as quickly by the dendrites of other neurons
- reaction time lengthens
- multitasking becomes harder
- processing takes longer
- complex working-memory taste become virtually impossible
(A few individuals experience significant brain loss w age)
Define mortality
Death
Define morbidity
Disease, the rates of which depend partly on diagnosis
Define disability
The usual result of morbidity, is the inability to do something that people usually do.
(Ex: vision loss)
Define vitality
Some people with morbid conditions that increase disability and the risk of mortality are nonetheless happy and active
What’s the leading cause of death for adults 25-65?
Cancer (due to lifestyle)
What are the smoking rates in the U.S?
- Lung cancer deaths for 55-64 yr old males are about half what they were in 1970
- women’s smoking has increased over time (rates for women’s lung cancer deaths has increased) (doubling from 1980-2008)
- long-term effects of smoking include reduced oxygen intake and this lower vitality
- cancer deaths are decreasing in most developed nations, including the U.S
How much does metabolism decrease between the ages 20-60?
1/3
Define stressor
Any situation, event, experience, or other stimulus that causes a person to feel stressed
Define problem-focused coping
A strategy to deal with stress by tackling a stressful situation directly
Define emotion-focused coping
A strategy to deal with stress by changing feelings about the stressor rather than changing the stressor itself
Define general intelligence (g)
The idea of g assumes that intelligence is one basic trait, underlying all cognitive abilities.
What is the Flynn effect?
The rise in average IQ scores that has occurred over the decades in many nations
Define Seattle-longitudinal study
The first cross-sequential study of adult intelligence. Study from 1956-2005
Define fluid intelligence
Those types of basic intelligence that make learning of all sorts quick and thorough.
(Abilities such a short-term memory, abstract thought, and speed of thinking are all usually considered parts of fluid intelligence)
Define crystallized intelligence
Those types of intellectual ability that reflect accumulated learning.
(vocabulary and general information are examples. Some developmental psychologists think crystallized intelligence increases with age, while fluid intelligence declines)
