Midterms Flashcards
Ageism
a form of discrimination against older adults based on their age.
Paul Baltes’ 4 key features
multidirectionality, plasticity, historical context, multiple causation
Multidirectionality
development involves both growth and decline; as people grow in one area, they may lose in another and at different rates.
Plasticity
skills can be trained or improved with practice even later on in life
Historical context
each of us develops within a particular set of circumstances determined the historical time in which we are born and the culture in which we grow up
Multiple causation
how people develop results from a wide variety of forces: biological, psychological, sociocultural, and life-cycle forces.
Primary aging
normal, disease-free development during adulthood
Secondary aging
developmental changes that are related to disease, lifestyle, and other environmentally induced changes that are not inevitable
Tertiary aging
rapid losses that occur shortly before death
Nature-nurture issue
involves the degree to which genetics or hereditary influences (nature) and experiential or environmental influences (nurture) determine the kind of person you are.
Stability-change issue
concerns the degree to which people remain the same over time
Continuity-discontinuity controversy
concerns whether a particular developmental phenomenon represents a smooth progression over time (continuity) or a series of abrupt shifts (discontinuity)
Culture
share basic values, norms, beliefs, habits, ways of living
Ethnicity
sense of identification (ancestral/national)
Universal vs. context specific development controversy
oncerns whether there is just one path of development or several
Longitudinal study
the same individuals are observed or tested repeatedly at different points in their lives
Cross-sectional study
developmental differences are identified by testing people of different ages at the same time.
Cellular theories
a cell can only divide a limited number of times. Telomeres (tips of chromosomes) if healthy, regulates cell division. Enzyme telomerase if insufficient reproduce to smaller size.
Cross-linking theory
certain proteins in human cells interact randomly and produce molecules that are linked in such a way as to make the body stiffer.
Free radicals theory
aging is caused by unstable reactive molecules
Changes in skin
wrinkles, age spots, moles, less pigment, varicose veins, thinner and drier skin
Changes in hair
hair loss caused by destruction of germ centers. Males don’t lose facial hair. Females gain facial hair.
Changes in voices
decrease volume and pitch, breathlessness and trembling, less pronunciation
Changes in body build
decrease in height (compression of the spine) weight gain then loss.
Changes in mobility
muscles and strength loss: age 70- up to 20%. Age 80- up to 40%. No gender differences. Bones loss begin in late 30s, faster in 50s, slows at 70s
Changes in vision
decrease in light, farsightedness, cataracts (opaques spots), glaucoma (high fluid pressure), macular degeneration
Changes in hearing
damage due to loud environment
Changes in touch
somesthesia (body sensitivity to touch): pain perception, decrease in sexual pleasure. Balance: dizziness and vertigo: the fear of falling and actual falls.
