Adulthood
Although adulthood begins sometimes after mid-twenties. Defining adulthood into stages is more
difficult than defining stages during childhood or adolescence.

Physical Development
Peak of physical performance occurs around 20 years of age, after which it declines imperceptibly for most of us.

Middle Adulthood
Muscular strength, reaction time, sensory abilities and cardiac output begin to decline
after mid-twenties. Around 50, women go through menopause; and men experience decreased levels of hormones and fertility.

Old Age: Life Expectancy
Life expectancy at birth from 49% in 1950 to 67% in 2004, and to 80% in developed countries. Women outlive men and out
number them at most ages.

Old Age: Sensory Abilities
After age 70, hearing, distance perception, and the sense of smell diminish, as do
muscle strength, reaction time and stamina. After 80, neural processes slow down,
especially for complex tasks.

Old Age: Motor Abilities
At 70, our motor abilities also decline. A 70-year old is no match for a 20 year old
individual. Fatal accidents also increase around this age.

Old Age: Dementia
With increasing age the risk of dementia also increases. Dementia is not a normal
part of growing old.

Old Age: Alzheimer’s Disease
Alzheimer’s disease also increases with age. Individuals who are in the early stages of this disease show more MRI activity in the brain than normals of the same age.

Cognitive Development
Do cognitive abilities like memory, creativity, and intelligence decline with
aging, the way physical abilities do?
![Page 12: Adulthood, and Reflections on Development Module 10](https://reader035.fdocuments.us/reader035/viewer/2022062517/56813b05550346895da3a735/html5/thumbnails/12.jpg)
12
Aging and Memory
As we age we remember some
things well. These include recent past events and events that happened a decade or two
back. However, recalling names
declines.
![Page 13: Adulthood, and Reflections on Development Module 10](https://reader035.fdocuments.us/reader035/viewer/2022062517/56813b05550346895da3a735/html5/thumbnails/13.jpg)

Aging and Memory
Recognition memory does not decline with aging, and material that is meaningful is
recalled better than meaningless material. The same is true for prospective memory
(remember to …).

14
Aging and Intelligence
Longitudinal studies suggest that
intelligence remains relatively stable as we
age. It is believed today that fluid
intelligence (ability to reason speedily)
declines with age, but not crystalline
intelligence (accumulated
knowledge and skills).

15
Aging and Other Abilities
A number of cognitive abilities decline with age.
However, vocabulary and
general knowledge increases with age.

Social Development
Many differences between young and old are not simply based on physical and
cognitive abilities, but may be based on life events associated with family, relationships
and work.

Adulthood’s Ages and Stages
Psychologists doubt that adults pass through an
orderly sequences of age-bound
stages. Mid-life crises at 40 are
less likely to occur than crises
triggered by major events (divorce, new marriage).
Neuroticism scores, 10,000 subjects(McCrae & Costa, 1996).

Adulthood’s Commitments
Love and work are defining themes in adult life. Evolutionary psychologists believe that
commitment has survival value. Parents that stayed together were likely to leave a
viable future generation.

Well Being Across the Life Span
Well being and people’s feelings of satisfaction are stable across the life span.

Death and Dying
There is no “normal” reaction or series of grief stages after the death of a loved one. Grief is more sudden
if death occurs unexpectedly. People who reach a sense of
integrity in life (in Erickson’s terms) see
life as meaningful and worthwhile.

Developmental Issues
Researchers viewing development as a slow continuous process are generally those who emphasize experience and learning. Biologists, on the other hand view maturation and development as a
series of genetically predisposed steps or stages. These include psychologists like
Piaget, Kohlberg and Erickson.

Developmental Issues
Lifelong development features both stability and change. Personality gradually
stabilizes as people age. However, this does not mean that our traits do not
change over a lifetime. Some temperaments are more stable than
others.
