- Cognitive Ageing
- Gerentology - the scientific study of ageing
- According to gerontologists 60-65 is when physical and psychological changes take place
- BROMLEY (1988)
- With normal ageing, brain decreases in weight by 10-15%
- Cross-sectional designs: Independent groups but cohort effects are involved
- - different standards of healthcare - changes in education/ technology
- Longitudinal designs: Repeated measures but practice effects are involved
- Also drop out due to death/illness/moving away
- Language is the only thing which does not decline with age
- SALTHOUSE (2005): The effect of ageing on reasoning
- Comprehension - don't understand what is required of them
- Slower at processing and responding
- Strategy may be different
- MAY ET AL. (1999)
- Age-related decline on WM tasks is due to inhibiting irrelevant information
- Episodic memory - memory of a specific event
- Declines with age
- NAVEH-BENJAMIN (2000)
- Associative deficit hypothesis - older adults have difficulty associating information together
- Recollection is a slower process
- Cells in hippocampi die with age so rely on familiarity
- Recollection is a slower process
- Associative deficit hypothesis - older adults have difficulty associating information together
- Prospective Memory - remembering to do something in the future
- perform ongoing task but divert memory
- What = action When = cue to perform
- what = buy milk when = after lecture
- Self-initiate action
- Older adults show higher commitment to completing tasks
- Semantic Memory - factual and general knowledge
- vocabulary
- Does not decline with age but changes still seen
- Increased difficulty with word finding - tip of the toungue
- Not meaningful to talk about processing speed independent of the task
- How do you compensate for declines?
- 1. Episodic memory ~ strategy training 2.Prospective Memory ~ external aids
- Gerentology - the scientific study of ageing
