Commonly Used Psychological Tests Flashcards
What are the 5 factors within the Stanford-Binet Intelligence Scale, and who was it modelled off?
Based upon the Cattell-Horn-Carroll Model of Intelligence (hierarchical model).
- Fluid Reasoning (intelligence)
- Knowledge (crystallised intelligence)
- Quantitative reasoning (numeric ability)
- Visual-spatial reasoning
- Working memory (short-term)
How do you interpret the Stanford-Binet Intelligence Scale?
55-69: Mildly Impaired
90-109: Average
130-144: Gifted
What is the WPPSI-IV?
WPPSI-IV: Wechsler Pre-School and Primary Scale of Intelligence (4th Edition) - For 3-7 year olds
What is the WISC-V?
Wechsler Intelligence Scale for Children (5th Edition) - For 6-16 year olds
What is the WAIS-IV?
Wechsler Adult Intelligence Scale (4th Edition) - For 16 years upwards
What is the WASI-II?
Wechsler Abbreviated Scale of Intelligence (2nd Edition) - 30 minute and 15 minute versions
Which of the Wechsler tests have the most overlap?
WPPSI-IV
WISC-V
WAIS-IV
What are the five primary scores on the WISC-V?
Verbal comprehension
Visual perceptual
Fluid reasoning
Working memory
Processing speed
These can be combined to form a measure of general intellectual functioning (Full Scale IQ). The tests can be given on a pair of linked iPads.
How do you interpret the WISC-V?
< 69: Extremely low
90-109: Average
> 130: Very superior
What is the Raven’s Progressive Matrices (RPM) test?
A non-verbal group ability test delivered for ages 5 and upward. Language is not required, and it was designed to assess military recruits independent of educational factors.
What evidence is there that the RPM is a valid measure?
Correlates with other aptitude tests and to a lesser degree with academic ability (though correlations not high)
What is the version of the RPM used for the general population?
Standard Progressive Matrices
What is the Peabody Picture Vocabulary Test (PPVT)?
A multiple choice test for people aged between 2 and upward that only requires a pointing response. It provides a rough measure of IQ for people who may not be able to do the Binet or Wechsler tests, although it is not a substitute.
When might the PPVT be inappropriate to deliver?
When the participant is unable to hear.
What are the psychometric properties of the PPVT?
Reliability (alternative forms: .87 - .93, internal consistency: .96 - .97, test-retest coefficients: .92 - .96)
Content Validity (all words in the dictionary)
Empirical Validity:
1. Test scores increase with age as predicted
2. Convergent validity (correlates well with other established vocabulary tests)
3. Special populations were found to score as expected (mental retardation, developmental delay, autism and language disorder)
