Week 12 Flashcards
Neuropsychology
what does neuropsychology study
brain-behaviour relationships
intelligence is a general mental capacity that among other things involves these 7 things…ability to:
reason, plan, solve problems, think abstractly, comprehend complex ideas, learn quickly, learn from experience
what is the Flynn effect?
substantial and long-sustained increase in both fluid and crystallized intelligence measured in many parts of the world from 1930 - present. each time IQ tests are re-standardised we seem to get smarter….
the Flynn effect may be explained by these 4 factors:
schooling & test familiarity, change in environment I.e internet exposure, nutrition improvements, decrease in disease & better health
what is Wechsler’s take on intelligence?
global capacity of a person to act purposefully, to think rationally, & to deal effectively in their environment
6 strengths of the Wechsler scales
well known, normative data, rigorous standardisation, good reliability, stable IQ & index cores,co-linking with other tests within the Wechsler family
what does it mean by normative data in the Wechsler tests?
large sample size across age groups, rigorous inclusion criteria, matched to pop & demographic characteristics (sex, ed, ethnicity, religion)
Wechsler viewed intelligence not in terms of capacity (quantity of knowledge) but in terms of
intellectual performance (how one uses their intelligence)
Wechsler scale weaknesses x2
easy to ‘over-interpret’ (esp individual subtests); missing exploration of executive functioning, personality & social intelligence;
4 reasons you’d use Wechsler testing
intelligence testing; explore learning disorders; explore giftedness; strengths & weaknesses
what standard score range (IQ) & percentile rank range would you expect to see from romaine with ‘very superior’ intelligence?
130+ ranked higher than 98-99.99% of pop
what standard score range (IQ) & percentile rank range would you expect to see from romaine with ‘superior’ intelligence?
120-129 ranked higher than 91-97% of pop
what standard score range (IQ); percentile rank range would you expect to see from romaine with ‘high average’ intelligence?
110-119 ranked higher than 75-90% of pop
what standard score range (IQ) &; percentile rank range would you expect to see from romaine with ‘average’ intelligence?
90-109 ranked higher than 25-73% higher than pop
what standard score range (IQ) would you expect to see from someone with ‘extremely low’ intelligence?
69 & below
wechsler test results are discussed in terms of
standard scores and percentiles
what is the average range most scores fall between for the Wechsler tests?
-3 to +3
what does a scaled score of 19 mean in a Wechsler subtext?
vet superior intelligence (99.9 percentile)
what does a scaled score of 8-11 mean in a Wechsler subtext?
average intelligence (25-63 percentile)
what are the 3 subtexts in the perceptual reasoning index?
block design, matrix reasoning, visual puzzles
what’s involved with block design?
make designs using coloured cubes.
what does block design subtest measure?
visuoconstruction ability, spatial awareness
what’s involved with the matrix reasoning subtext in the perceptual reasoning index?
given an incomplete pattern & asked to fill it in from several options
what’s measured with the matrix reasoning subtext in the perceptual reasoning index?
(untimed) non-verbal reasoning
