W7 - stability change and ageing Flashcards
What is trait expression influenced by?
- social demands
- expectations
- social values
- biology
- individual circumstances
- these factors change with age
What can be used to assess visual and spatial ability?
block design task
- involved a series of 9 blocks that the individual has to rearrange to create a pattern
- thesis easy to administer but does not distinguish between visual and spatial ability
What do WAIS test scores suggest about age?
that intelligence does decline as we age in general
- but different cohorts could have scored differently due to different experiences
What are the subsets of WAIS? (hold and don’t hold)
Hold = verbal scale - resistant to cognitive/age decline (info; comprehension; arithmetic etc) used on those with dementia and brain injury etc
Don’t hold = performance scale - cognitive/age decline sensitive (digit symbol; picture completion; block design etc)
Welchsler abbreviated scale of intelligence?
- can test anyone from 6-90 years old
- scores are adjusted to age for comparison
What are the four subsets of WASI?
Vocal = word and picture description
similarities = picture/word shared characteristics
block design = pattern completion with blocks
matrix reasoning = pattern completion on paper
Difference between fluid and crystallised intelligence?
Fluid = innate intellectual power, think logically to solve new problems, not learnt crystallised = uses experience, education, 'wisdom' and knowledge is learnt
Hampson & Goldberg 2006 study on the stability of the big 5…
- used 2404 school children
- followed up in 1998-2004
- suggested that greater coefficients across 40 years for extroversion conscientiousness than for openness, agreeableness and neuroticism
- level of neuroticism changed over age
Milojev & Sibley 2014 study on personality across the lifespan
- survey of 3910 New Zealanders aged from 20-80
- ranked order of scores was relatively stable
- levels of stability varied
- increased stability 20x and 50s but decreased stability 50+ to age 80
- extraversion was most stable
- personality is not all that stable
What is the default mode network?
- a large scale brain network best known to be active when a person is not focused on the outside world and the brain is at wakeful rest
e. g. self-reference, thinking abut others, moral reasoning, autobiographical details
Simon et al 2018 - associations between personality and the DMN using fMRI
- 365 individuals aged 20-80
- looked at brain function into age decline and dementia risk
- openness positively related to connectivity in the DMN
- neuroticism was negatively associated with both ventral and dorsal attention networked
agreeableness was negatively related with dorsal attention network
Do we change as much as we think study?
WOODRUFF 1983
- 1944 tested for personal and social adjustment
25 years later tested again
- people changed less than they thought they had
this criticised because it relied on self report measure ad memory that naturally declines over time
What is disengagement theory?
Cumming & Henry 1961
- emotional “blunting” with age - you feel less as you get older
- idea that older people are more withdrawn from society
