Validity of the Slosson Intelligence Test: A ten-year review

Ten years of validity research concerning the Slosson Intelligence Test (SIT) is reviewed. The equivalence of the SIT to the Stanford-Binet and the Wechsler Scales is examined and the relationship of the SIT to achievement measures is described. The importance of supplementing correlational findings with regression analysis, mean difference data, and information on misclassification is emphasized by the reviewers. Decisions concerning individuals based on SIT IQ scores are viewed as particularly risky in situations involving groups of subjects characterized by a relatively narrow range of IQ scores.     

Predictive validity of the Slosson Intelligence Test with the WISC-R and the WRAT-R level 1

Slosson Intelligence Tests (SITS) administered by school guidance counselors correlated significantly with school psychologist administered WISC-Rs (r=.75). The Slosson IQ correlated significantly higher with the WISC-R Verbal IQ than with the Performance IQ score. The mean Slosson IQ was a statistically significant 4.4 points higher than the mean WISC-R Full Scale IQ (p<.01).     

Selecting gifted children with the Slosson Intelligence Test: 1981 vs. 1961 norms

The Slosson Intelligence Test (SIT) for Children and Adults protocols for 683 gifted students ranging in age from 6 to 12 years were scored using both 1961 and 1981 norms. The average 1981 norm score was 5.17 points lower than the 1961 norm score. The differences increase with the age of the child. Implications for using the SIT for selecting gifted children are discussed.

Comparison of reading disabled children's scores on the WISC-R,Peabody Picture Vocabulary Test,and Slosson Intelligence Test

Scores on the Slosson Intelligence Test and Peabody Picture Vocabulary Test, two frequently used screening devices, are examined to determine how well they predict scores on the Wechsler Intelligence Scale for Children—Revised. Two hundred seven children representing reading disabled children in the average classroom were administered each of the three measures of this study. The degree of relationship between the PPVT and the WISC-R was found to be.57, and the degree of relationship between the SIT and the WISC-R was found to be.73. The results of this study suggest that the PPVT and SIT measure different and/or limited aspects of a child's ability as measured by the WISC-R and are therefore only rough estimates of capacity to function in situations requiring what is generally termed intelligence.     

Race differences on the developmental test of Visual Motor Integration,the Slosson Intelligence Test,and the ABC Inventory

Preschoolers' scores on the Developmental Test of Visual Motor Integration (VMI), the Slosson Intelligence Test (SIT), and the ABC Inventory (ABCI) were analyzed for race and sex differences. Separate ANOVAs revealed no race effect on the VMI, whereas race differences favoring whites were found for the SIT and ABCI. There were no effects for sex on any measure, nor were there any interactions. Results are discussed in terms of the inconsistent findings for race effects in the perceptual-motor literature.     

The Slosson as a predictor of Wide Range Achievement Test performance

This study investigated the efficacy of predicting academic achievement as measured by the Wide Range Achievement Test, using the Slosson Intelligence Test For Children and Adults as the predictor. Ninety-five children referred for psychological evaluations in a five-county area in southeastern Nebraska were given both instruments, and a regression analysis was conducted where the Slosson IQ scores were separately regressed on Reading, Spelling and Arithmetic standard scores from the Wide Range Achievement Test. The results indicated that the Slosson IQ significantly predicts Wide Range standard scores. Derived regression equations are reported.     

动态测验:当代智力测验的新发展

随着心理学和认知科学的进一步发展,人们对智力活动的动态过程有了更深刻的认识,动态测验从一种动态的角度来评价个体的智力,能够弥补传统静态测验的缺陷和不足,这正成为西方当代心理和教育测验研究与应用领域的一大热点。目前国外最有代表性的动态测验有学习潜能评估工具、学习潜能测验、过程学习测验和认知加工测验。
