Factors extracted from the normative samples of the Wechsler Intelligence Scale for Children Performance Scale (WISC PS), Wechsler Intelligence Scale for Children-Revised Performance Scale (WISC-R PS), and Hiskey Nebraska Test of Learning Aptitude (HNTLA) are compared to factors emerging from deaf normative samples on these nonverbal intelligence…

Two hundred seventy-four boys and girls, aged 7 through 15 years, participated in a test-retest reliability study of the Developmental Tests of Visual-Motor Association. Test-retest correlations for the total group and subjects comprising categories A through D were significant. (Author/SJL)

Lynn [Lynn, R., 2002. Sex differences on the progressive matrices among 15-16 year olds: some data from South Africa. "Personality and Individual Differences 33," 669-673.] proposed that biologically based developmental sex differences produce different IQ trajectories across childhood and adolescence. To test this theory we analyzed the…

A study examining the relationship between nonverbal intelligence and academic achievement in 53 hearing impaired 7-18 year olds supported using the Hickey-Nebraska Test of Learning Aptitude (along with other measures) in interpreting individual differences in the academic achievement of hearing impaired students. (Author/CL)

Examined the relationship between the Peabody Picture Vocabulary Test-Revised (PPVT-R), the Peabody Picture Vocabulary Test (PPVT) and the Wechsler Intelligence Scale for Children-Revised (WISC-R) with incarcerated delinquents (N=35). Results indicated that the PPVT-R yielded a higher correlation with the WISC-R verbal IQ scores than did the PPVT.…

Corman and Escalona's scales for Object Permanence and Spatial Relationships were administered to 98 severely and profoundly retarded children on three occasions, with intervals of six months between successive administrations. The findings demonstrated the high stability of the scales when environmental conditions are themselves highly stable.…

When administered to 125 deaf youngsters, ages 5-12, the WISC performance test had good reliability and predictive validity, but administration to some young or physically handicapped children proved difficult. The Colored Progressive Matrices proved satisfactory with older subjects, but its suitability for younger deaf children was not confirmed.…

Reviews research concerning relationship of nonverbal ability measures recommended for hearing impaired students and learning potential. Reviews both earlier studies indicating that nonverbal measures could be used to predict academic achievement and more recent studies urging caution or suggest questionable predictability when interpreting data.…

The Non-Verbal Test of Cognitive Skills (NTCS), by Boyd and Johnson, attempts to address the problems of non-verbal and culturally biased testing instruments in three directions: (1) Test items should be developed which cannot be linked to a specific culture or environmental source as previous learning; (2) Assumed language facility should be…

A study of 33 elementary/middle school deaf children correlated Wechsler Intelligence Scale for Children-Revised Performance Intelligence Quotients (IQs) with Stanford Achievement Test-Hearing Impaired Edition (SAT-HI) grade equivalents and age-based percentiles. A second study of 64 children correlated nonverbal IQs from many tests with SAT-HI…

Data from 104 school children were analyzed to determine the psychometric and conceptual soundness of the Universal Nonverbal Intelligence Test (UNIT), devised for children with limited English language proficiency. Examines test validity through construct validity, confirmatory factor analysis, and exploratory factor analysis in comparison with…

Validity evidence from several studies for a nonverbal measure of self-esteem, the Sliding Person Test (SPERT), is presented. Results of the studies indicate the utility of the measure for elementary through college students. (JKS)

The 50 nonverbal tests in this bibliography assess aptitude and cognitive skills using various nonverbal means, such as pictures, symbols, or figures. They are useful in testing those who may have reading difficulties or those for whom English is not the primary language. Not included are aptitude measure that have both verbal and nonverbal…

Students (N=178, aged 5-20) with severe/profound hearing losses were assessed on giftedness using nonverbal measures of intelligence, teacher nominations, and parent nominations. No statistical correlation was found among the three identification procedures. Teacher-generated characteristics of gifted hearing-impaired children were found to be…

Finds that extraverted children did better than introverted children on both a nonverbal coding task and simple and complex verbal fluency tasks. Notes that anxiety influenced girls' performances on the more complex verbal fluency task, but did not alter boys' performances. Compares these findings to those of similar studies of adults. (RL)
