Whether grouping children into special classes on the basis of IQ scores is educationally defensible was investigated using 492 educable mentally retarded (EMR) students, 12-15 years of age, during two field tests (1971-73). The curriculum used was the Me and My Environment biological sciences program. The following three test instruments were…

In order to initiate appropriate programs for screening, early intervention, and meaningful psycho-educational programs, a children's community mental health center in Harlem, where over 95 percent of its clientele is black and/or Spanish speaking, requires, for all its referrals, an accurate assessment of intellectual strengths via an IQ battery.…

Recent comprehensive analyses such as those by Harnishfeger and Wiley (1975) and Zajonc (1976) indicate the existence of a national and international downward trend in achievement and intelligence test scores. An analysis of the achievement and intelligence test scores in a small, upper middle class, New Jersey elementary school district showed an…

The effectiveness of test adaptation based on item selection and reordering of a Spanish (Mexican) version of the Peabody Picture Vocabulary Test (PPVT) was examined. Translated forms were administered to a sample of Mexican students. One item from each pair (A and B) was selected and reordered using a priori rules. The revised instrument was…

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. (Author)

Whether "psychometric" and "Piagetian" kinds of intelligence are similar is a question of whether they have similar courses of development with age. When using factor analysis to address this issue, age effects must be eliminated in order to assess relations among measured constructs. Reanalyses of previous results were…

This study of 852 subjects in Barcelona (Spain) between 4 and 9 years old estimated the degree of consistency among elements of the Borelli-Oleron Performance Scale by taking into account item clusters and subtest clusters. The internal consistency of the subtests rose when all ages were analyzed jointly. (SLD)

The factor structure of the Wechsler Intelligence Scale for Children (Revised) was examined in the standardization sample using new methods of factor analysis. The substantial overlap across factors was most parsimoniously represented by a single general factor. Implications for public policy regarding the purposes and outcomes of special…

The possibilities of influence of the race of testers on the intellectual performance of children were investigated. A four factorial design, with two response measures--the digit span and block design subtests of the Wechsler Intelligence Scale for Children--was employed. These data were gathered on students enrolled in a black and white…

Contents of this book include: an introductory preface by C. Loring Brace; "Introduction to Jensenism," C. Loring Brace; "Can we and should we study race differences?" Arthur R. Jensen; "Intelligence in Black and White," Alexander Alland, Jr.; "Whose is the failure?" Vera John; "The influence of…

Jensen (1969) proposed a two-factor model of intelligence by which mental abilities can be divided into memory and higher mental processes labeled "Level I" and "Level II" respectively. This study employed statistical methods characteristic of construct validation to examine a battery of memory, intelligence, and achievement…

Torrance's longitudinal study predicting adult creative achievement was reexamined employing a multiple regression analysis. Application to 211 cases found that 4 predictors explained 49% of the total variance in adult creative achievement. They were creativity test score, childhood future career image, intelligence test score, and the existence…

"The Bell Curve" by Richard J. Herrnstein and Charles Murray has generated enormous debate as a result of its claim that there is a connection between race and intelligence. The essays of this collection respond to "The Bell Curve" in various ways. Taken together, the following offer an antidote to a work of dubious premises…

This article responds to a critique of a study in which an ambitious program of thinking skills instruction was designed, implemented, and evaluated. Concepts of intelligence and thinking skills are explored, the relationship between the two is analyzed, and the impact of instruction on both is considered. (IAH)

The validity is questioned of testing the intelligence of Mexican Americans via intelligence tests constructed for Anglo Americans. An overview is included of the literature concerned with the comparability of intelligence scores. Critiques are presented of 9 current studies utilizing intelligence test scores of Mexican Americans and Anglo…
