Psychological Assessment: Brief Descriptions-Test Biases:oSlope Bias –occurs withdifferential validity. (Validity coefficients for apredictordiffer for different groups;predictor is more accurate for one group than for anothergroup.)oIntercept Bias– (=unfairness) Validity coefficientsandcriterion performance fordifferent groups are the samebutmean scoreson the predictor differ.The predictorconsistently underestimates performance on the criterion for members of one of thegroups.-IQ tests:oStanford-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, forensicoWAIS-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 fromVerbal Comprehensionand Perceptual Reasoning. General cognitive ability, assessing intellectual ability ofolder adolescents and adults.oWISC-IV– Same scoring, indexes as WAIS-IV, for children up to age 16:11.oWPPSI-III– Preschool and early school-age (up to age 7:3). Get Verbal, Performanceand FSIQoKABC-II, KBIT-2– KBIT-2=brief screening for intelligence; KABC-II = culture-fair (b/c ofdecreased reliance on verbal instructions/responses.) Based on CHC model or Luria’sneuropsych processing model. (Luria’s recommended for culture-fair scoring/interp).Screens crystallized and fluid intell.oCAS– based on PASS model (ID’d by Luria:Planning, Attention, Simultaneousprocessing, Sequential processing.)oSlosson Tests– SIT-P-1, SIT – RS-1. SIT-P-1 = preschool children; SIT-R3-1 = childrenand adults. Screening tests; crystallized intell. Useful forvisual impairments.oWoodcock-Johnson III – (WJ III COG and WJ III ACH)cognitive abilities andachievements. Based on CHC model-Infant and Preschool Tests:oDenver Developmental Screening Test –brief, assess developmental delays up to 5yrs. Four domains:personal-social, fine motor adaptive, language, gross motor. DDscored if an item is failed that 90% of children usually pass at a younger age. Can beadministered by paraprofessionalsoBayley Scales –(Bayley – III) Current developmental status, up to 42 months (4years).Five domains:Cognitive, Motor, Language, Social-Emotional, AdaptiveBehavior.
oFagan Test of Infant Intelligence –(FTII) Information processing a good predictor ofchildhood IQ. Selective attention to novel stimuli. Up to 12 mos, ID mentalretardation or other cognitive impairmento-Measures for People with Disabilities:oColumbia Mental Maturity Scale (CMMS) –Children (3:6 – 9:11), general reasoningability.Does not require verbal responses or fine motor skills. Developed for childrenwith cerebral palsy, also used for mental retardation, brain damage, speechimpairments, hearing loss, limited English proficiency.
