Life Span Developmental Theories or models
Development requires multidimensional models
Change involves gains and losses throughout life
– Gains are most obvious early in life
– Losses are more obvious later
Adaptation to change involves three global process
– Growth: Adding new characteristics, understandings, skills
– Maintenance or resilience: Finding ways to continue or restore functioning after loss
– Regulation of loss: Adjusting expectations and accepting a lower level of functioning
Success
maximizing gains, minimizing losses
n Stability in the Big 5 personality traits after age 30
Biological causes are implicated- Sources of Stability in Adult Development
– Related to brain-mediated systems of approach, fear
irritability, effortful control, and reactivity
– Stable differences in reactivity, stress response
Environmental influences equally important- sources of stability in Adult Development
– Predictable responses from others
– Relatively stable environments for many
Personality traits across cultures
Age-graded change
Change as a function of time
Physical changes in adulthood
– Declines in sensory ability, reproductive ability
– Changes in appearance, wrinkles, weight
Cognitive changes in adulthood
– Decline in fluid/mechanical processes, processing speed and inhibition mechanisms
– Stable or increasing crystallized resources, declarative and procedural knowledge
Life tasks and responsibilities in adulthood
– Fairly predictable sequence of change in roles
Erikson: Three stages in self-development in adulthood
Vaillant suggested two more adult life stages should be added to Erikson’s
- Keeper of meaning vs. rigidity (late middle adulthood)
Development is influenced by the intersection of…
– Chronological age (life time)
– Family-related roles (family time)
– Membership in a birth cohort (historical time)
History-graded Changes
Nonnormative events
Key Developmental Tasks of Midlife
The family life cycle
1. Normative stage like sequence of roles and experiences – Leaving home as single young adults – Finding a compatible mate – Joining of families through marriage – Families with young children – Families with adolescents – Launching children and moving on – Families in later life
Theories of marital harmony and discord
Multidimensional model for marriage
– Intrapersonal factors: Traits, expectations
– Interpersonal factors: Problem-solving skills
– Situational factors: Stresses, environment
– Developmental factors: Transitions, role change
Predicting marital success or satisfaction so far
– More successful when positive outweighs negative
– Negative affect reciprocity predicts dissolution
– “Four horsemen of the apocalypse” are criticism, defensiveness, contempt, and stonewalling
