ageing and decision making

Question 1

poor decision making due to ?

Answer 1

slow processing speed
reduced working memory capacity
unable to suppress irrelevant content

Question 2

cognitive reserve?

Answer 2

neural flexibility
cognitive stratagies
moderates negitive influence of brain deterioration in cognitive performance

Question 3

STAC-r

Answer 3

scaffolding theory of ageing and cognition

Question 4

what is scaffolding theory

Answer 4

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

Question 5

who came up with scaffolding theory

Answer 5

lorenze and parker 2014

Question 6

positive effects on cogintive domains

Answer 6

executive functioning
memory
language

Question 7

what does physcial activity lead to

Answer 7

higher cognitive abilities in old age
different aspects of cognition improved

Question 8

ageing on the brain

Answer 8

gray matter reduces in frontal and parietal regions

Question 9

neuromodulation theories

Answer 9

changes are driven by neurotransmitter systems
changes in dopamine, seratonin and glutamate systms contribute to changes in decision making

Question 10

complex processes

Answer 10

processing reward,
estimating value,
uncertainties
using experience to help

Question 11

decision mechanisms bottom up

Answer 11

ventral tegmental area
amygdala
anterior insula

Question 12

top down

Answer 12

lateral prefrontal context
posterior parietal context

Question 13

neurodegeneration?

Answer 13

degeneration of nervous system especially neurons
typically genetic

Question 14

contributing factors to degredation

Answer 14

mitochondrial mutation
inflation

Question 14

what happens with neurodegeneration

Answer 14

loss of structure and function of neurons,
cell death no cure

Question 15

Alzheimer

Answer 15

loss of neurons and synapses in cortical and sub cortical structure
described dementia in 1906

Question 16

symptoms

Answer 16

memory loss
difficulty thinking
difficulty with porblem solving
language problems

Question 17

frontotemporal dementia symptoms

Answer 17

personality changes
langauge difficulties
loss of interest in daily activities
weakness

Question 18

lewy body dementia

Answer 18

abnormal deposits in brain

Question 19

Answer 19

acetycholine
dopamine

Question 20

diagnosis criteria emerged

Answer 20

1990s

Question 21

neuroplacisity

Answer 21

decline in structure and function of brain with natural ageing
sucsessfull ageing relys on placisity

Question 22

can placisity be improved

Answer 22

scaffolding theory model, suggests that certain activites can help, meditation or physical activities

Question 23

neuroplasticity and cognitive ageing

Answer 23

scaffolding theory of aging
goh and park 2009
lorenze and park 2014

Question 24

what helps scaffolding

Answer 24

brain structure and function life experiences

Question 25

current research

Answer 25

spacial navigation varies across lifespan

Question 27

what were the elements to it

Answer 27

1. way finding 2.path integration 3.spacial working memory

Question 28

finding related to ageing

Answer 28

liner decline in spacial ability 19-70 70 spacial ability increased

Question 29

why increase after 70

Answer 29

selection bias more cognitive capabilities
