Scatter on the revised Wechsler Intelligence Scale for children (WISC-R) was evaluated for 105 learning disabled (LD) children. Scatter was defined as range of scaled scores on: (1) five regular verbal tests; (2) five regular performance tests; and (3) all 10 regular subtests. Pairwise combinations of 11 subtests were also evaluated for deviations…

The contribution of heredity to scores on a digit span intelligence test, Jensen's Memory for Numbers, was estimated with a standard heritability formula. The test measures level I mental ability--the capacity to store and recall, but not ability to elaborate or manipulate stimuli. Subjects were 35 monozygotic (MZ) twins and 35 same-sex dizygotic…

The British Education Act of 1944 stipulated that instruction and training be offered according to the ages, abilities, and aptitudes of pupils. One specific problem concerned the entry to secondary schools of pupils from a variety of primary schools. The resulting problem of determining the different aptitudes and abilities has been partially…

This study sought to determine the appropriateness of two conventional intelligence tests for assessing the ability of economically deprived young adults participating in job training programs by comparing their test results with those of the test standardization groups. The Wechsler Adult Intelligence Scale (WAIS), and the Langmuir Oral Direction…

The purpose of the three-year Cooperative Language Development Project was to examine the efficacy of an oral language development program and an experimental reading program in improving the academic achievement, language development, intellectual functioning, and creative thinking of disadvantaged children in primary grades. The experimental…

High school teachers and counselors, especially those concerned with the lower grade levels, should take into consideration a student's socioeconomic background along with his intellective factors whenever his academic performance is predicted. In lower grades where intelligence tests cannot be given effectively, socioeconomic status (SES) index…

In an effort to isolate the emergence and causes of social class differences in intellectual performance, this longitudinal study was undertaken as a follow-up on a cross-sectional study that yielded no social class differences on the Cattell Infant Intelligence Scale for 12-, 18-, and 24-month-old black children. In the present study, 89 children…

This study investigates the effect of socio-economic level (lower and upper-middle), race (black and white), and sex on locus of control of reinforcement scores, and the relationship between the latter scores and reading achievement in a sample of 211 second grade children. A stratified random sampling technique insured adequate levels of each…

Arthur R. Jensen's article presented no new data: it only reorganized a biased sample of already existent data. Nevertheless, it has been taken by opponents of school integration as definitive scientific evidence of the innate inequality of black and white students. Jensen and Van Den Haag advocate additional studies on individual learning ability…

Two studies are reported. The first is based on Piaget's assertion that the child's representation of his world is dependent on the level of cognitive development at which he is currently functioning. Forty-eight normals and 48 retardates were given a visual memory task. They were asked to recall a configural presentation in a number of ways,…

This collection of essays about intelligence stems from the revived nature-nurture controversy about the origins of mental abilities, led notably by Arthur Jensen, whose article in 1969 created a furore in the U.S.A., and more lately by H. J. Eysenck in Britain. In planning this book, an attempt has been made to step back from the debate itself…

This illustrated booklet describes research procedures in the Infant Laboratory of the Educational Testing Service to investigate measurable factors in infant behavior which can predict intellectual potential. The research is currently focusing on attending, the manner in which infants respond to various stimuli presented to them during their…

Urban EMR students' WISC-R scores (N=20) were compared with their previously administered WISC scores. The results of this study indicated that WISC-R scores in comparison to WISC scores appeared to be more stable in the lower IQ ranges and less vulnerable to cultural bias. (Author)

A review of research regarding the connection between intelligence and language proficiency precedes the description of an investigation indicating that inductive reasoning and intelligence can be clearly distinguished from general language proficiency. A language proficiency and reasoning test in English is appended. (CB)

Examines misclassification of Native Canadian students' abilities with standardized intelligence test results. Wechsler Intelligence Scale for Children-Revised (particularly verbal scale) results often reflect extent of acculturation, not personal capabilities. Paper indicates areas of needed research to find more appropriate ways of assessing…
