Compares the performances on psychometric and Piagetian measures of intelligence at school entry of children of different ethnic groups living within a dominant Western-type culture. In general, few significant differences between the ethnic groups are found. (Author/AM)

In this study, cognitive processes hypothesized to be relevant to the digit symbol task of the Wechsler Adult Intelligence Scale (WAIS) were examined. Fifty-two undergraduate education students were divided into four groups to receive four different treatments. All the students took the digit symbol test, followed immediately by a test of their…

In investigations of decline of intellectual status with age, cross-sectional and longitudinal studies give divergent results--the former show almost universal declines in test performances among older groups while the latter often show gains. Although few structure-of-intellect (SI) factors have been explored in relation to adult ages, two kinds…

The relationship between attention and reading achievement in first graders was investigated for 48 boys and 33 girls in five first-grade classrooms of the Bridgewater-Raritan Regional School District in New Jersey. The statistical analysis provided separate data for boys and girls in regard to the relationship between reading achievement and…

Relationships between school achievement and two theoretically different measures of intelligence, Piagetian and psychometric, are explored in 143 bright, average, and retarded elementary school students. Factor analyses of the California Test of Mental Maturity, the Metropolitan Achievement Test, the Stanford-Binet, and fifteen Piaget-type tasks…

The study investigated the feasibility of M. Budoff and M. Friedman's (1964) learning potential paradigm as an assessment approach with 40 moderately and severely mentally retarded persons (aged 12 to 22 years). Ss were tested three times: initially, after one week, and after one month with a match-to-sample block design test. Twenty of the Ss…

Forty-three students participated in a laboratory experiment involving estimation of qualitative similarity between items sampled from ten conventional tests of intellectual performance. Estimated similarity could tentatively be described as a function of positive inter-test correlations as determined from another group of 123 individuals with the…

Both sides of a long standing and apparently still heated argument are reviewed and presented. Are males more variable in intelligence than females? In an attempt to answer the question the author employed data from a longitudinal growth study. Results indicated that sex differences in variability on individual subtests of the Wechsler…

An historical overview of investigations concerned with delineating the structure and composition of infant intellectual activity is presented. Earlier conceptualizations characterized infant intelligence as a unitary trait or factor. Recent studies contend that infant intellectual activity is comprised of varied sets of relatively independent…

A battery of 16 newly devised tests intended as measures of "fluid" intelligence were administered, together with a number of other measures, and factor analyzed separately for a sample of Black children and a sample of White children. The results were judged to confirm the construct of fluid intelligence. (CTM)

Cyril Burt presented data in his paper that were in perfect agreement with a genetic theory of IQ and social class. A detailed analysis of these data reveals that they were fabricated from a theoretical normal curve, from a genetic regression equation, and from figures published more than 30 years before Burt completed his surveys.

A total of 72 school psychologists administered both the WISC and WISC-R to 164 black, white and Latino children. These children had been referred to the school psychologist because of concerns about their intellectual ability. Significant WISC/WISC-R differences were found, with the WISC-R yielding lower results. (Author)

The aim of this paper was to develop a simplification of Sattler's technique (in the form of a table) to make it easier to use and to apply to the Binet profile of any child tested. An illustration is included. (Author)

The author cites a 1939 study by H. Skeels and H. Dye in which the IQs of retarded infants in orphanages were increased after exposure to substitute mothering, and reviews current behavior modification research to support the contention that intelligence can be increased. (CL)
