Q

Lumper VS Splitter INT Theories

A

Lumpers believe INT is 1, tapped by all COG abilities. Splitters believe INT is composed of diff. varying w/ independence.

Splitters:
-Ability used depends on COG activity engaged in
-Some brain areas DEV more than others
-EX: There are many ways to travel (walk, run, drive, plane, ect)

Q

Of INT models/Ths, who is right?

A

It depends! Vernon’s Hierarchal model resolves debates between lumpers & splitters

Vernon’s Hierarchal Model: g(eneral) INT factor at top, broader factors in following LVLS (Verbal & Practical INT)
-Specific factors in each broad lvl
-g: Verbal (education) & Practical (Spatial & mech.)
*Verbal: Vocal, arithmetic
*Practical: BD, OA, Mazes

Cattel-Horn-Carroll (CHC) Th.

A

Most used hierarchal model
-Cattel: Fluid VS Crystal INT
-Horn: Extends g(f) & g(c), adding broad abilities
-Carroll: Brings together decades of factor analysis rsch, makes “big picture” of INT

g is still at top, broad abilities in 2nd tier, narrow abilities at bottom

29
Q

Structure of S-B5

A

-Is a hierarchical model test partly based on Cattel’s th.
-Full Scale IQ (FSIQ): Composite score based on 10 subtests
-M = 100, SD = 15

30
Q

The two domains of the S-B5

A

Nonverbal IQ & Verbal IQ
-M = 100, SD = 15
-Each domain based on 5 subtests
-The 5 subtests test the 5 factors
-Not all subtests given if client has disability

31
Q

The two domains of the S-B5 pt 2

A

5 factors, of 2 domains, makes 1 full IQ test
-Each factor based on 2 subtests, NV & V
-Similar to 5 index score
-10 subtests total
*M = 10, SD = 3

32
Q

Administration of S-B5

A

Starts w/ 2 routing subtests (1 NV, 1 V), estimating client’s ability lvls , which determines use of following subtests
-Routing tests also estimate g/over all ability
-NV fluid reasoning first, then V know.

After routing tests:
-Remaining 4 NV tests given
-Then 4 remaining V tests
-Wechsler alternates NV & V tests

33
Q

S-B5 Start point

A

-Based on age for routing tests
-Based on subsequent routing test performance
-Reverse rule for when items are too hard
-Goal: Est. basal lvl w/ inital items
*Items in order of diff., credit given for items below basal

34
Q

S-B5 Stop Rule

A

Test stops when too hard, client misses several times
-Determines ceiling lvl
-Processing spd not relevent
*Some gifted children work slowly and carefully

35
Q

37
Q

Wechsler series

A

Wechsler adult INT scale 4th ed (WAIS-IV, 2008)
-Ages 16-90&11m
-WAIS-V in process

W INT Scale for Children, 5th ed (WISC-V, 2014)

W Preschool & Primary Scale of INT, 4th ed (WPPSI-IV, 2012)
-Ages 2&6m-7&7m

Similarity in administration, scoring, & interpretation.

38
Q

Origin of W Scale

A

1932, W worked at Bellevue Hospital, working w/ psych. patients

1939, W-B test publicized
-Test items borrowed from early tests like the Binet-Simon, Army-Alpha, & Army Beta
-Work w/ psych. patients, W aware of non-INT factors influence test performance

39
Q

Why was the W-B test made?

A

To correct flaws from earlier ass. tests
-Appeals to adults
-L emphasis on V Qs & spd
-M emphasis on accuracy
-Mental age
-Deviation IQ: Scored compared to M performance of others the same age

40
Q

IQ Constancy

A

IQ ~ stable w/ normal aging after early childhood
-Position may not change as self & peers learn w/ age

41
Q

Different subtests on W-scale

A

Varying COG test, WISC-V has 21 subtests (8 are new)
-10 primary subtests commonly used b/c yields FSIQ & 5 Primary index scores
-6 secondary subtests provide boarder sampling of INT functioning
-5 Complimentary subtests to measure skills of ass. w/ learning diff.

42
Q

General Feat. of W-test

A

Some subtests involve V & performance tasks
-Hands on, visual, NV

Not all subtests given if client has disability interfering w/ V or performance tasks
-Info gathered on phys., Lang., or sensory limits before administering test

43
Q

General Feat. of W-test pt 2

A

Is hierarchical model
-Full scale IQ (M = 100, SD = 15)
-5 primary index scale
-Primary & 2ndary subtests (M = 10, SD = 3)
-Examiner can analyze profile of STR & WK instead of looking at just IQ

Across the 3 W-tests some subtests allow “apple to apple” comparison if client is retested through school

A

Determined by age of client if kid
-Demonstration items, practice samples, & teaching items (feedback) for some subtests
-Items INC in diff. to initially build success
-Reversal rule
-Basal lvl

52
Q

WISC-V stop point

A

When failing scores occur in a row
-Discontinue if 0 remain
-Ceiling lvl: Client can’t get correct

53
Q

Why add to old tests?

A

-Reflect advancements in field (5PI)
-Makes relevant to sample b/c culture bias
*Flynn Effect: IQ INC 3pts/decade
*AVG IQ w/ WISC-3 in ‘91 = ~100, WISC-4 in ‘03 = 100

54
Q

Additions to older test

A

-L floor, H ceiling
-Improved items & art work, adding new subtests
-A test age rng INC, DEC spd & movement importance

55
Q

Rel. of WISC-V

A

Full IQ better than subtests b/c is whole
-Primary & secondary L, but good

Yes on content, no for prediction
