  1. Developing Through the Life Span Adulthood Physical Development

  2. Physical Changes in Middle Adulthood Credit: Bettmann/Corbis Age 27 Physical abilities peak in the mid-20s.

  3. Physical Changes in Later Life Credit: Jose Luis Pelaez Sensory abilities decline in later adulthood. For example, older adults may develop a condition called presbycusis—a loss of sensitivity to high-pitched tones—which may cause difficulty in comprehending speech. Declining sensory abilities also leave older adults at a higher risk for accidents of various types…

  4. Physical Changes in Later Life

  5. Physical Changes in Later Life Credit: Alan Oddie/PhotoEdit There is also a very steep rise in the incidence of dementia—the most common cause of which is Alzheimer’s Disease,a neurological disease which strikes 3% of the world’s population by the age of 75. Underlying Alzheimer’s is a loss of brain cells and deterioration of neurons that produce the neurotransmitter acetylcholine.

  7. Developing Through the Life Span Adulthood Cognitive Development

  8. Aging and Memory In this study, young adults and older adults were given new names to remember once, twice, or three times. In all conditions, young adults outperformed older adults.

  9. Aging and Intelligence There are also large age-related declines in tests of fluid intelligence—tests of abstract reasoning where prior experience is of no benefit.

  10. Aging and Intelligence However, the good news is that there are age-related increases, or at least stability, in scores on tests of crystallized intelligence—tests that tap our accumulated knowledge. Above, age-related increases in number of clues solved in a New York Times crossword puzzle.

  11. Aging and Intelligence This is one explanation for the paradox of aging—the observation that adults can maintain high levels of skill throughout adulthood despite declines in fluid intelligence.

  15. Aging and Intelligence More good news is that physical activity—and especially aerobic exercise—has been found to boost cognitive functioning in older adults. Credit: Rick Doyle/Corbis

  16. Aging and Intelligence There is also some evidence to suggest that intellectual activity prevents age-related decline in cognition, but the jury is still out on this issue.

  18. Developing Through the Life Span Adulthood Social Development

  19. Adulthood’s Ages, Stages, and Commitments Credit: Diego Grez Across the life span, there are changes in our social roles. For example, many people become spouses and eventually parents. As children begin to absorb time, money, and energy, marital satisfaction may decline.

  20. Adulthood’s Ages, Stages, and Commitments However, there are popular misconceptions about social development. There is no evidence for increased incidence of an emotional “mid-life crisis” in the 40s. In fact, males are emotionally more stable in their 40s.

  21. Well-Being Across the Life Span And although older adults are obviously closer to death than young adults, happiness tends to be higher on average in older adults than middle-aged adults.

  22. Well-Being Across the Life Span Successful aging: Biological, psychological, and social-cultural factors affect the way we age. With the right genes, we have a good chance of aging successfully if we maintain a positive outlook, and if we remain active and connected to social networks.

  23. Chapter Review What are the major physical, cognitive, and social milestones in childhood, adolescence? How did Piaget conceptualize development, and what are the major stages in his theory? What did Harlow’s research reveal about the origin of attachment in infants?

  24. Chapter Review What are some of the major changes in cognition in adulthood? What is the paradox of aging, and what might explain it?
