How to interpret WPPSI3 using a CHC framework?




Here is the WPPSI3 (2002) structure for ages 4:0-7:3  


Processing speed

performance
verbal
General verbal ability
Symbol search

Block design
Information
Receptive vocabulary
coding

Matrix reasoning
Vocabulary
Picture naming

Picture concepts

Word reasoning


Picture completion

Comprehension


Object assembly

Similarities



And here is the CHC  classification of the WPPSI3 test.  This is taken from:


Alfonso, V. C., Flanagan, D.P. and Radwan, S.  The impact of the Cattell Horn Carroll Theory on test development and interpretation of cognitive and academic abilities.  In: Flanagan, Dawn P and Harrison, Patti L.  Contemporary Intellectual Assessment. Second edition, 2005.  The Guilford Press.


Crystallized knowledge
Fluid ability
Visual processing
Processing speed

Vocabulary
Matrix reasoning
Block design
Symbol search

Information
Picture concepts

Object assembly

coding

Similarities

Picture completion


Comprehension




Receptive vocabulary




Picture naming




Word reasoning






Here is the WPPSI4 (2012) test structure.     This information is taken the PEARSON site at: 


Working memory
Verbal comprehension

Fluid ability
Visual spatial
Processing speed

Picture memory –
The child views a stimulus page of one or more
pictures for a specified time and then selects the
pictures from options on a response page.
Information
Matrix reasoning
Block design
Bug search
(like symbol search)

Zoo locations – The child views one or more animal cards
placed on a zoo layout for a specified time
and then places each card in the previously
viewed locations
Similarities
Picture concepts

Object assembly

cancellation


Vocabulary


Animal coding
(like coding)


Comprehension





Receptive vocabulary





 Picture naming







We can see that the WPPSI4 structure is in line with the CHC classifications of the WPPSI3  test.  This increases the legitimacy of interpreting the WPPSI3 within CHC framework.
