Chapter 8 Flashcards
What are the 3 different kinds of aging?
-biological aging: declines in physical health
-psychological aging: mix of growth, decline, stability
-social aging: stressful intersections of work and family demands
What are the 2 components of biological aging?
-Primary aging: biological factors; molecular and cellular changes; oxidative damage
-Secondary aging: lifestyle factors; lack of physical exercise; poor diet
What are the physical changes in adulthood?
-graying and thinning hair
-loose skin and wrinkles
-loss of muscle mass (sarcopenia)
-decreased lung efficiency
-cholesterol and fat accumulation
-decreased immune function
-sensory loss (vision and hearing)
-hormonal changes
What are some age-related vision problems?
-presbyopia: inability to focus on nearby objects
-floaters: little spots (“cobwebs”) that float around the field of vision
-drop in scotopic sensitivity (ability to see in dimmer light)
-dry eye syndrome: eye doesn’t produce tears properly (evaporate quickly)
What are 3 components of menopause?
-climacteric: midlife transition when fertility declines
-perimenopause: ovaries stop releasing eggs & decreased estrogen & progesterone
-menopause: 12 months without menstruation (gradual process of physical change)
What are some symptoms of menopause?
-inability to fall asleep
-hot flash (surge of adrenaline produces sweat, disturb sleep)
-vaginal lubrication diminishes & becomes waterier
-osteoporosis: decreased bone mass
What is the #1 cause of death?
-heart disease
-atherosclerosis: a buildup of fatty plaque in the arteries, which is the most common cause of cardiovascular disease
What is hypertension?
-high blood pressure
-when the blood flows with a greater force than normal
-when uncontrolled, it can damage the brain’s white matter –> cognitive problems later in life
What is the #2 cause of death?
-cancer
-most common type is breast cancer
-next most common are lung and prostate cancer
What is rheumatoid arthritis (RA)?
-inflammatory disease that causes pain, swelling, stiffness, and loss of function in the joints
-RA is the 2nd most common form of arthritis after osteoarthritis, which is the normal wear and tear on the joints
What are common digestive problems?
-prolonged problems with heartburn can lead to more serious complications, including esophageal cancer, one of the most lethal forms of cancer in the U.S.
-gallstones are present in ~20% of women and 10% of men over the age of 55
What sleep disorders are common?
-9% of Americans are diagnosed with a sleep disorder
-of those 71% have sleep apnea
-24% suffer from insomnia
How is cognitive functioning affected by age?
-some individuals in middle age have improved cognitive functioning
-amount of white matter (forms connections among neurons) increases into the 50s before
What is the difference between fluid and crystallized intelligence?
-fluid: abstract reasoning (flexible thinking); mechanics of cognition; peaks in mid 20s then declines
-crystallized: derived from previous experience; accumulated knowledge and expertise; increases until age 50+; pragmatics of cognition
How does fluid and crystallized intelligence change with age?
-fluid intelligence increases til age 30, then gradual decline
-crystallized intelligence increases gradually across life
-most dramatic decline from 25 to 88 is shown in perceptual speed & processing speed
-2nd most dramatic decline is in numeric ability
How is information processing affected in middle adulthood?
-crystallized intelligence compensates for declines in fluid intelligence
-information input is compromised
-processing speed slows
-self-regulation stabilizes
-expertise grows
How do older adults learn?
-students over 35 accounted for 17% of all college and graduate students in 2009
-older adults may take longer to learn material, but they are less likely to forget it quickly
-older adults are more task-oriented learners and want to organize their activity around problem-solving
What is the Plus 50 Initiative?
-assists community college in creating or expanding programs that focus on workforce training and new careers for the plus-50 population
What is the difference between expertise and novice?
-expertise: specialized skills and knowledge that pertain to a particular topic or activity (intuitive, automatic, strategic, and flexible)
-novice: someone who has limited experiences with a particular task
How does expertise affect an individuals career?
-expertise is one reason why many people often reach the top of their career in middle adulthood
-superior performance of older adults compared to younger novices is task specific
What are the characteristics of work in midlife?
-work performance is positively affected by crystallized intelligence
-general stability in employment
-expertise, seniority, and responsibility
-increased risk for burnout (39% work 50hrs+/week)
-job satisfaction tends to peak (do job well & lower expectations and goals)
