Stereotypes, Cognition & Intelligence Flashcards

1
Q

Explain the study by Levy et al. about countering the effects of age stereotypes on physical function

A

Participants were told to hit a button if a word appeared above fixation and another if it appeared below. It is implicit priming because they see a flash but can’t process the word.

They were randomly assigned to either positive age stereotypes (intervention) or neutral (control) words.

Those in the intervention showed improvement in the self-perception of aging as well as much more positive age stereotypes than the control.

There was a similar improvement in physical function for the intervention group than the control.

The amazing thing is this effect lasted a number of weeks.

Q

What are the 2 objectives in the study of adult intelligence?

A
  1. determine whether adults at different ages also differ in intellectual performance at a particular moment in time
  2. how intelligence changes within individuals over the course of their lifetimes.

Q

What did Schaie do in 1996 to spark the big data collection debate?

A

Measures the same cognitive abilities over the same ages with longitudinal and cross sectional data.

Q

What does Schaie’s data from the longitudinal design show? (4)

A
  1. tend to see growth up until late 30s and early 40s.
  2. After this, there is stability over the course of a few decades
  3. 60s is when decline begins but often in abilities that are not central to their lives anymore (numerical ability, perceptual speed)
  4. No decline seen by anyone in all measures until the age of 88
  5. the decline is not as severe as we once thought.

Q

What does Schaie’s data from the cross-sectional design show? (3)

A
  1. Most abilities you see a gradual, steady decline after late 20s
  2. even when there is stability it is different from the longitudinal data
  3. Perceptual speed does decline in both

Q

Why could there be such a difference across these data sets?

A

cohort effects. If you were interested in cognitive development you would be in error to use cross- sectional due to the cohort effects.

Q

What was salthouse’s response to Schaie? (4)

A
  1. Dismissed Schaie’s arguement
  2. believes cognitive decline starts early and is steep over the lifespan.
  3. Dismissed the cohort effects - says they are more of a generational effect so nbd, we don’t know what contributes to cohort effects.
  4. Says practice effects explain the longitudinal data and that performance is being inflated. Says decline would be more extreme without them (BUT HOW BC 7 YEARS BETWEEN EACH TEST TIME)

Q

What is schaie’s response to Salthouse’s comments other than being heavily pissed off? (2)

A
  1. said age changes are different than age differences! That they could only identical with a stable environment and level of performance between successive birth cohorts at the same age.
  2. Test re-test data are inadequate
    - 5 of salthouse’s 12 tests didn’t show practice effects

Q

What was Nilson’s take on the whole debate between Schaie and Salthouse? (3)

A
  1. Says they are generalizing across cognitive domains inappropriately
  2. If you squint your eyes there is stability, Salthouse wants to see a rapid decline but there is relative stability.
  3. the declines are starting to happen later than Salthouse wants to admit. he’s over claiming that there are these rapid declines in cognitive abilities.

Q

What did spearman think he could do? Was he kind of right ?

A

Thought he could come up with one measure “G” to define someone’s intelligence. Yes… it works for kids but not adults

Q

What was the purpose of having performance IQ on the older WAIS?

A

Since language is so deeply imbedded in culture, its hard to translate without having some disadvantage. So, he tried to compromise by including a performance section.

Q

The Modern IW test contains subsets?

A

10 “core” subsets

5 “supplemental” subsets

18
Q

What are four indices in these subsets?

A

o Verbal comprehension
o Perceptual reasoning
o Working memory
o Processing speed

19
Q

Q

“in what way are a radio and a television alike?” is a question for which indices?

A

Q

Cattell divided G into two distinct abilities:

A

Crystallized and Fluid intelligence

28
Q

What is Gc?

A

Based on education training, ability to use learned knowledge, skills and experience

29
Q

What is Gf?

A

Based on education training, capacity to reason and solve novel problems independent of any knowledge from the past.

A

Many tests designed specifically to measure Gf

Gf at some point

34
Q

In longitudinal and cross sectional studies, how do Gc and Gf look?

A

- Gf seems to show a steady decline throughout the lifespan

35

widespread across all functions

39
Q

In a 7 year study on individual difference what was found?

A

o There is decline, stability and gains in each of the age groups tested
o So there is huge overlap in individual differences

40
Q

Is there massive individual difference that underlies cognitive ability? T or F

A

TRUE

41
Q

What are the individual differences in relation to white matter?

A
  • there are people at 50 showing decline but those that are also showing increases
  • obviously there is a trend of decline but there’s major individual difference
