2- development adult Flashcards
(developmental) psychology’s major issues
- continuity and stages (continuous vs discrete) depends on framing
- stability and change (stable vs changing)
- nature AND nurture
nature and nurture
- look at interaction between them! best way to study
- poorly understood
heritability estimate
describes variance, not correlation
basically looks for the shared variance between IQ and genes
0.5
Piaget
- infancy and Childhood: Cognitive Development
- Worked at Binet’s school!
- Also used his own kids! - believed that kids are not passive vessel but ACTIVE THINKERS
- thought that children’s ability to understand objects was a cognitive skill that develops slowly as a child matures and interacts with the environment.
deprivation of attachment
Important note: we are resilient, we bounce back quickly
§ Higher risk for attachment problems, substance abuse, other poor outcomes (BUT see above)
Moral action for adolescents
Feeds moral attitudes
§ Mischel & marshmallows, again
§ i.e. self-control predicts future self-regulation
- actions shape our intuitions
- when thoughts =/= actions… actions win! cognitive dissonance
early adulthood physical development
physical benefits: muscle, health
middle adult physical development
biggest predictor of this is FITNESS LEVELS!!
- healthier brains when you’re older too!
Late adulthood physical development
- late adulthood is a new psychological phenomenon
- reaction and processing time slows down a little
aging and memory middle adulthood
- active recall gets worse
- buuuuuut recognition memory is the same
late adulthood aging and memory
- more bias in how you process information
- attend to irrelevant and meaningless information less but still good with meaningful and positive stimuli
end of life aging and memory
last 4 years of life
- decline in cognition and memory
Alzheimer’s disease
- A neurocognitive disorder (NCD) Most common cause of dementia
- Tremendous incidence in older adults
- Occasional early onset from genetics, but otherwise no single gene associated with AD
- No cure
early symptoms of AD
selective declines in memory
later symptoms of AD
confusion, irritability, anxiety,
deterioration of speech
Advanced stages of AD
difficulties with even simple responses or behaviours (e.g. swallowing, bladder control)
The defining characteristics of AD
- Brain volume decrease (at first is just loss of synapses)
- Neurofibrillary tangles
- Amyloid plaques
plaques
one of the earliest markers of AD
likely the end result of processes long processing in silence
Amyloid cascade hypothesis
plaques cause AD
Neurofibrillary (or tau) hypothesis
tangles cause AD
buuutttt they show up later than plaques so eh
