ageing and decision making Flashcards
learn
poor decision making due to ?
slow processing speed
reduced working memory capacity
unable to suppress irrelevant content
cognitive reserve?
neural flexibility
cognitive stratagies
moderates negitive influence of brain deterioration in cognitive performance
STAC-r
scaffolding theory of ageing and cognition
what is scaffolding theory
functional changes with aging are part of a lifespan process of compensatory cognitive scaffolding that is an attempt to alleviate the cognitive declines associated with aging
who came up with scaffolding theory
lorenze and parker 2014
positive effects on cogintive domains
executive functioning
memory
language
what does physcial activity lead to
higher cognitive abilities in old age
different aspects of cognition improved
ageing on the brain
gray matter reduces in frontal and parietal regions
neuromodulation theories
changes are driven by neurotransmitter systems
changes in dopamine, seratonin and glutamate systms contribute to changes in decision making
complex processes
processing reward,
estimating value,
uncertainties
using experience to help
decision mechanisms bottom up
ventral tegmental area
amygdala
anterior insula
top down
lateral prefrontal context
posterior parietal context
neurodegeneration?
degeneration of nervous system especially neurons
typically genetic
contributing factors to degredation
mitochondrial mutation
inflation
what happens with neurodegeneration
loss of structure and function of neurons,
cell death no cure
