A regression equation relating verbal and full-scale IQs was derived from scores of patients. Scores were highly correlated, and verbal IQ significantly exceeded full-scale IQ. Regression estimates closely estimated mean full-scale IQ, suggesting that the verbal scale serves effectively as a WAIS abbreviation. (Author)

The test-retest reliability and predictive validity of developmental quotients (DQs) derived from the Cattell Infant Intelligence Scale was assessed with 83 children with mental retardation, age 30 months or more. Scores were impressively stable on retest. DQs derived from the Bayley Scales of Infant Development were superior to Cattell DQs in…

The purpose of this paper is to evaluate the reliability of the Wechsler Preschool and Primary Scale of Intelligence and to measure whether this reliability is affected when subjects are from a disadvantaged group. The subjects were 25 male and 24 female 5 1/2-year-old poor Mexican-Americans. Generally, the Wechsler Preschool Scale showed high…

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. Results indicate that the Slosson IQ significantly predicts Wide Range standard scores. (Author)

Major presumptions that underlie the use of early intelligence tests are presented and disputed, centering on the construct of early intelligence, reliability, prediction, standardized administration, professional acceptability, utility for decision making, and congruence with Public Law 99-457. Professional solidarity is urged in opposing the…

Infant intelligence from birth until the age of two was measured to determine the usefulness of infant intelligence tests. Twenty infants were tested regularly over the two-year period. Results showed neither simplex nor other long-term patterns of interrelationship among the infant intelligence scores obtained. The study concludes that the…

This study analyzed and tested the equivalence of Forms A and B of the California Critical Thinking Skills Test (CCTST). In designing the CCTST, Form A was composed of 34 items from a bank of 200. To develop a parallel measure, Form B was developed by rewriting 28 of the 34 items and rearranging their order. Study participants were all entering…

The study, involving 379 students (6-20 years old), investigated the 3-year performance stability of handicapped children from four racial groups (Anglo, Black, Mexican American, and Native American). Data were collected from the Wechsler Intelligence Scale for Children--Revised (WISC-R) and the Wide Range Achievement Test (WRAT). Results…

Investigated the efficacy of various WAIS short forms among outpatients. Results favor Pauker's (1963) short form but also show a decrease in correspondence between short-form and Full Scale scores when the short forms are administered separately. (Author/EJT)

THE RELATIVE EFFECTIVENESS OF TASK SCORES VERSUS IQ AS PREDICTORS OF ACADEMIC ACHIEVEMENT WAS INVESTIGATED, AND THE CORRELATIONS BETWEEN TASK SCORES AND IQ RE-EXAMINED. SUBJECTS WERE 99 UPPER-MIDDLE CLASS ELEMENTARY SCHOOL CHILDREN WITH A MEAN STANFORD-BINET IQ OF 126 (SD EQUALS 19). THE INSTRUMENTS USED WERE DUNN'S OBJECT SORTING TASK (OST),…

The predictive power of the Split-Half version of the Wechsler Intelligence Scale for Children--Revised (WISC-R) Object Assembly (OA) subtest was compared to that of the full administration of the OA subtest. A cohort of 218 male and 49 female adolescent offenders detained in a Texas juvenile detention facility between 1990 and 1992 was used. The…

A Group of children were given the Otis Lennon Mental Abilities Tests in grades 3, 5, and 7, to measure the degree of score consistency over time. The test predicted future academic success only moderately well in grade 5 and slightly, if at all, in grade 3. (Author/SJL)

The ability of the Slosson Intelligence Test to predict academic achievement was assessed by using three samples of pre-kindergarten pupils from three successive years in a large midwest school district. Results indicate a moderately good predictive power of the instrument. (Author/JKS)
