In this study, the role of need for cognition, achievement motivation, and conscientiousness on academic underachievement was investigated. Forty-seven male and 46 female students in Grades 7 to 10 participated in the study. Student attributes were assessed by self-report measures, school performance by academic grades, and intellectual abilities…

The aim of the current study was to compare the Wechsler Intelligence Scale for Children-Third Edition, UK adaptation (WISC-III[superscript uk]) scores of Indian primary school children when Indian and UK norms are used. The sample consisted of 300 primary school children, within the age range of 6 years to 10 years and 11 months. The children…

Inspection of the 1972 revised norms for the Stanford-Binet demonstrate that the average mental age for a particular chronological age (CA) no longer numerically corresponds to that CA. Thus, mental ages derived from the test cannot any longer be interpreted as mental ages. A table of test ages based on the 1972 norms is provided. (Author)

The Wechsler Intelligence Scale for Children was administered to 80 retarded youngsters from ages 6 to 16 years. The factors found for the retarded children are similar to those found for normal children. This similarity suggests there may be no qualitative differences in intelligence structure for normal and retarded children. (Author/SJL)

Characterizes intelligence in terms of learning processes and uses the concepts and methods of other disciplines to understand how the conditions responsible for the development of its constituent processes and the manner of their organization lead to variations in effectiveness of intellectual functioning.

Periodically, fears are voiced that the intelligence level of the United States population is falling. Historically, this fear has been linked to the belief that fertility is inversely related to intelligence. Evidence for that belief is sparse and may be an artifact of the failure of researchers to consider completed families. An inverse…

The multitrait-multimethod matrix was used to determine the convergent and divergent validity of the conceptual tempo. (Author/BJG)

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…

Attention is drawn to the ways in which current conceptions of intelligence and its measurement differ from those which were generally accepted in 1928. The following principles underlying intelligence testing were generally agreed upon in 1928: (1) the assumption of intelligence as a recognizable attribute, responsible for differences among…

A brief discussion of theories of general intelligence precedes a report of relevant empirical data. Results from the factor analysis of more than 20 sets of Wechsler Adult Intelligence Scale (WAIS) data indicate that the WAIS clearly is not a one-factor scale. It does not measure a single, general intelligence. Roughly 17 percent of the reliable…

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 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…

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)
