Psychological Assessment: Brief Descriptions
- Test Biases:
o Slope Bias – occurs with differential validity . (Validity coefficients for a predictor
differ for different groups; predictor is more accurate for one group than for another
group .)
o Intercept Bias – (= unfairness ) Validity coefficients and criterion performance for
different groups are the same but mean scores on the predictor differ. The predictor
consistently underestimates performance on the criterion for members of one of the
groups .
- IQ tests:
o Stanford-Binet 5 – uses routing subtests (Object Series/Matrices – nonverbal;
Vocabulary – verbal) Subtest scores (M=10, SD=3) and Composite Scores/FSIQ
(M=100, SD=15) ; general cognitive ability, psychoeducational evaluation, d(x)
disabilities/exceptionalities – also career, neuropsych, forensic
o WAIS-IV – Four Indexes ( Working Memory, Verbal Comprehension, Processing Speed,
Perceptual Reasoning ). Subtest scores (M=10, SD=3) and Composite Scores/FSIQ
(=Index Scores) (M=100, SD=15); General Ability Index from Verbal Comprehension
and Perceptual Reasoning. General cognitive ability, assessing intellectual ability of
older adolescents and adults.
o WISC - IV – Same scoring, indexes as WAIS-IV, for children up to age 16:11.
o WPPSI - III – Preschool and early school-age (up to age 7:3). Get Verbal, Performance
and FSIQ
o KABC - II, KBIT-2 – KBIT-2=brief screening for intelligence; KABC-II = culture-fair (b/c of
decreased reliance on verbal instructions/responses.) Based on CHC model or Luria’s
neuropsych processing model. (Luria’s recommended for culture-fair scoring/interp).
Screens crystallized and fluid intell.
o CAS – based on PASS model (ID’d by Luria: Planning, Attention, Simultaneous
processing, Sequential processing. )
o Slosson Tests – SIT-P-1, SIT – RS-1. SIT-P-1 = preschool children; SIT-R3-1 = children
and adults. Screening tests; crystallized intell. Useful for visual impairments .
o Woodcock - Johnson III – (WJ III COG and WJ III ACH) cognitive abilities and
achievements. Based on CHC model
- Infant and Preschool Tests:
o Denver Developmental Screening Test – brief, assess developmental delays up to 5
yrs. Four domains: personal-social, fine motor adaptive, language, gross motor . DD
scored if an item is failed that 90% of children usually pass at a younger age. Can be
administered by paraprofessionals
o Bayley Scales – ( Bayley – III ) Current developmental status, up to 42 months (4
years).Five domains: Cognitive, Motor, Language, Social-Emotional, Adaptive
Behavior .

o Fagan Test of Infant Intelligence – ( FTII ) Information processing a good predictor of
childhood IQ. Selective attention to novel stimuli. Up to 12 mos, ID mental
retardation or other cognitive impairment
o
- Measures for People with Disabilities:
o Columbia Mental Maturity Scale (CMMS) – Children (3:6 – 9:11), general reasoning
ability. Does not require verbal responses or fine motor skills . Developed for children
with cerebral palsy, also used for mental retardation, brain damage, speech
impairments, hearing loss, limited English proficiency.
