Q

what is the Flynn effect?

A

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….

visuoconstruction ability, spatial awareness

23
Q

what’s involved with the matrix reasoning subtext in the perceptual reasoning index?

A

given an incomplete pattern & asked to fill it in from several options

24
Q

what’s measured with the matrix reasoning subtext in the perceptual reasoning index?

A

(untimed) non-verbal reasoning

25
Q

what’s involved with the visual puzzles subtext in the perceptual reasoning index?

A

asked to choose which patterns go together to make a 2D picture

26
Q

what’s measured with the visual puzzles subtext in the perceptual reasoning index?

A

spatial awareness

27
Q

what is perceptual reasoning?

A

ability to use info gained through the senses to make sense of them and make judgements about the world/or act accordingly

28
Q

what other visual puzzles are used in the perceptual reasoning index

A

figure weights, picture completion

29
Q

what three things are measured in the working memory index of the WAIS IV?

A

digit span, arithmetic, letter number sequencing

30
Q

what three subtests fall under the processing speed index of the WAIS IV?

A

coding, symbol search, cancellation (all timed)

31
Q

what’s involved with the coding subtext in the processing speed index?

A

quickly draw in the mark that matches the number from a specified key

32
Q

what does the coding subtext measure in the processing speed index?

A

clerical type speed, learning

33
Q

what’s involved with the symbol search subtext in the processing speed index?

A

asked to identify, from 2 shapes, if one of them is in a list of 5 other shapes

34
Q

what does the symbol search subtext measure in the processing speed index?

A

speed of visual searching

35
Q

what’s involved with the cancellation subtext in the processing speed index?

A

asked to cross out all matching shapes from a large page of them

36
Q

what does the cancelling subtext measure in the processing speed index?

A

speed of visual discrimination

37
Q

what is the first of four steps in scoring the WAIS IV?

A

score each subtest

38
Q

what is the 2nd of four steps in scoring the WAIS IV?

A

convert each subtest to a scaled score (ranges 1-19) using tables in the manual that are based on age, so each subtest has a meaningful score.

39
Q

what is the 3rd of four steps in scoring the WAIS IV?

A

add up subtest scores scores, & then convert to an index score (eg working mem index) using tables in the manual. mean of 100 SD of 15

40
Q

what is the fouth of four steps in scoring the WAIS IV?

A

create a full scale IQ by adding up the relevant subtests, & then again, using yet manual to convert to a score (mean=100, SD=15)

41
Q

what 5 areas of cognition does the WAIS IV test?

A

simple attention span, working memory, processing speed, language, spatial

42

which Wechsler test measure academic achievement?

A

WIAT III

43
Q

what ages does the WIAT III test?

A

children, adolescents, tertiary students, adults.

44
Q

how many subtests in the WIAT III?

A

16

45
Q

what types of academic skills are measured in the WIAT III? x5

A

listening, speaking, reading, writing, maths

Q

do participants have to do every subtest in the WIAT III?

A

no

47
Q

the WIAT III has 4 indexes what are they?

A

reading, maths, written language, oral language

48
Q

what is semantic memory?

A

facts, world knowledge

49
Q

what 2 cog areas does the Wechsler memory scale IV test?

A

memory and learning

50
Q

in memory and learning the Wechsler memory scale assesses these 6 things

A

encoding, storage, retrieval, recognition, working memory, semantic memory
