Resource summary
PAD Introduction
why study PAD?
ageing population
advance in life exp
implications for finance, healthcare, retirement, technology design
processing speed
Annotations:
Salthouse (1996)
limited time mechanism
early processing takes up disproportion amount of processing time
insufficient time for later stages
simultaniety mechanism
products from earlier processing may be lost by the time later processing is complete
global vs selective slowing
inhibition
Annotations:
Hasher & Zacks (1988)
working memory
difficulty focusing on target info and ignoring/inhibiting attention to irrelevant material
internal thoughts vs external distractions
preventing off task info entering WM
deleting or suppressing marginally relevant info in WM
restrains strong response emission before suppression is evaluated
sensory functions
Annotations:
Lindenberger & Baltes (1994)
Berling Ageing Study
age related variance in cognitive ability mediated by....
Visual and Auditory Acuity
frontal lobe theory
Annotations:
West (1996)
age related neural changes in frontal cortex
PFC reduction in volume, dendritic length and number
cognitive functions relying on frontal cortex will decline with age
support from episodic memory, STROOP task, WM
neural noise
Annotations:
Welford
neural circuits in the brain become increasingly noisy
signal to noise ratio decreases
ability to stay focused and concentrate deteriorates = deficits in cognitive performance
parallel with inhibitory mechanism but on a neural level
