Q

what is scaffolding theory

A

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

acetycholine
dopamine

20
Q

diagnosis criteria emerged

A

1990s

21
Q

neuroplacisity

A

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

22
Q

can placisity be improved

A

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

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

24

what helps scaffolding

A

brain structure and function
life experiences

25

Q

what were the elements to it

A
  1. way finding
    2.path integration
    3.spacial working memory
28
Q

finding related to ageing

A

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

29
Q

why increase after 70

A

selection bias
more cognitive capabilities
