Decrement Model
Aging as a period decline
Personal Growth Model
Concentrates on advantages of growing old
Cognitive Decline
Common belief regarding cognitive ability over the life-span
Brain Growth across the lifespan
Brain develops rapidly during last period of gestation & first 2 years
At 2 years old, brain is 80% of adult weight, but continues to develop through childhood and adolescence.
Peaks of growth at age 7, 12 & 15
Synaptic Pruning (elimination of unneeded synaptic connections) Up 50% reduction between ages 2-10, continues through adolescence and into young adulthood Brain reaches full maturity at around age 24 when synaptic pruning ceases
Cognitive Decline - IQ
Crystalised intelligence (Gc) increases as we age.
Fluid Intelligence (Gf) peaks between ages 20 and 30 and then decreases over time.
Physiological changes – cardiovascular / metabolic
RTs slow
Slowing of nervous system processes
Decline in sensory system performance may be a better indicator of change.
Memory Decreases
Decreases
Episodic – free recall
Compared to young adults, older adults tend to perform more poorly on than older adults on tests of free recall.
Working Memory
Contextual
For example repeating the same story to the same person a number of times.
Memory remains unchanged
Recognition
There is less difference between young and older adults on recognition tests
Short Term Memory
Procedural
Semantic
Though begins to decrease in mid 70s
Dementia – Separate to Cognitive Decline
The predominate factor for developing Alzheimer’s disease is age
Greater life expectancy has led to increased rates.
1% prevalence at age 65%
25% prevalence at age 85
Disease, not an acceleration of normal aging
Rates actually falling in developed countries.
Social disengagement theory (Cummings & Henry, 1961)
Mutual withdrawal of the aging individual from society and of society from the individual.
Retreat of the elderly into a more solitary existence
Withdrawal from society is a voluntary, and inevitable process and represents the most appropriate way of growing old.
Detrimental consequences of theory - encourages segregation and the belief that old age has no value (Bromley, 1988)
Do the elderly really disengage (Havighurst et al., 1968)?
Those who disengage the least are happiest and tend to live longer.
Several different personality types including reorganisers and disengaged.
Focuses on quantitative rather than qualitative changes (Cartensen, 1996)
Activity Theory (Havinghurst, 1964; Maddox, 1964)
Main alternative to Social Disengagement Theory
Old people have the same psychological and social needs as middle aged.
Isolation not mutual but result of withdrawal by ageist society.
Optimal aging can be achieved by staying active and resisting ‘shrinkage’ of social world.
Maintaining activities of middle age for as long as possible
Finding substitutes for work, spouses and friends.
Unrealisitic? Major activity of middle age is ‘productive’ employment (Bond et al., 1993).
Does SDT underestimate and AT overestimate degree of control people have in the reconstruction of their lives?
Some individuals seem happy to disengage – people might be left to choose the style of ageing most suited to their personalities.
Socio-emotional selectivity theory (Carstensen, 1992, 1993, 1995; Carstensen and Turk-Charles, 1994; Lang and Carstensen, 2002)
Social contact motivated by a number of goals. Survival Information-seeking, Development of self concept, Emotion regulation.
Importance of each varies throughout life – influenced by construal of the future:
Open ended = Long term goals are important
Limited future = Attention devoted to the present – emotional states become more salient.
Age related reduction in social contact appears to be highly selective rather than reflecting a reduced capacity
Younger people faced with own mortality, make similar decisions to those of the elderly (Carstensen, 1996).
Older individuals prioritise emotionally meaningful goals (Lang & Carstensen, 2002)
Age related reduction in social contact therefore selective. Individuals choose to focus on those who can give most emotional support.
Friendships increase life expectancy more than contact with family (Giles et al., 2005)
Fear of Death
Unique as human beings in that we are aware of our own mortality.
Death Terror – fear of death present within each human being.
Conflict – We want to live but know death is inevitable.
Is death anxiety related to age?
No greater self reported levels of death anxiety in elderly (Kastenbaum, 2000)
Age however may predict nature of anxiety (Stricherz & Cunnington, 1981, 1982)
Adolescents fear possible loss of loved one or death as punishment
Adults fear experiencing painful death
Retirees fear becoming helpless and dependent on others and the impact of their deaths on loved ones.
Further distinction between ‘young old’ (70s) and ‘old old’ (80s) (Munnichs, 1966)
Young Old – What should death mean to me at this stage.
Old Old – See prospect of death as a well-known, familiar phenomenon.
Anticipatory grief – Stages of Dying (Külbler-Ross, 1969)
Denial Anger Bargaining Depression Acceptance
Bereavement – Becoming a Widow(er)
Highly stressful and emotionally demanding!
Impact on two of Erikson’s key stages, intimacy and identity
Intimacy – loss of life partner.
Identity – Identity defining routines lost, changes in life roles, changes ch in social relationships,
Role of widow(er) not clearly defined in Western society
Standard against which other types of loss are measured.
Retirement
Significant transition
Achieved on the whole without great psychological stress
Three different responses to retirement (Kloep & Hendry, 2006):
High Distress
Work as a lifestyle
Life beyond work
Again reinforces the danger inherent in treating aged as one homogenous group.
Influences on Adult Development
Three kinds of influence on the way we develop…
Normative age-graded influences
Biological
Social
Non-Normative influences
Normative history-graded influences
Levenson et al. (1978) – Seasons of Man’s Life
Four Eras Pre-Adulthood – Age 0 - 22 Early Adulthood – Age 17 - 45 Middle Adulthood – Age 40 - 65 Late Adulthood – Age 60 onwards
Early Adult Transition (17 – 22)
Developmental bridge between adolescence and adulthood.
Two key themes – ‘separation’ and ‘formation of attachments to adult world’.
Entering the adult world (22 – 28)
Entry life structure for early adulthood
Novice phase
Create provisional structure for workable link between the ‘valued’ self and adult society
Women’s dreams and gender splitting.
‘Gender splitting’ occurs in adult development (Levison, 1986).
Men = Unified visions of future
Women = Dreams split between career and marriage
Disappointment and developmental tension? (Durkin, 1995)
Age 30 transition (28 – 33)
Opportunity to work on limitations and flaws of first life structure
Set foundations for more satisfactory structure for remaining young adulthood.
Settling Down (33-40)
Culminating life structure for early adulthood.
Consolidation of the second life structure
Shift away from tentative choices
Strong sense of commitment
Two substages early settling down (33-36) and becoming ones own man (BOOM)
Mid-life Transition (40 – 45)
Termination of early adulthood structure an initiation of new life structure.
Soul searching, questioning, what has my life meant so far?
Midlife Crisis
Is there a mid-life crisis (MLC)?
Levison et al. consider that crisis is inevitable, and necessary
No soul searching at this stage will … pay the price in a later developmental crisis or in a progressive withering of the self and a life structure minimally connected to the self. (Levinson et al., 1978)
Concept of MLC to narrow.
Adolescing (Marcia 1998) – making decisions about one’s identity occurs throughout the lifespan.
Symptoms of MLC such as divorce occur more frequently before middle age.
