Fifty-eight middle class children were tested over 6 years with 25 achievement, I.Q., and personality tests. Consistency of test results were evaluated by a variance comparison method and a simple signal detection model. Both methods lead to the conclusion that achievement tests are far better predictors than personality tests with I.Q. scales…

This study is concerned with the manner in which experience with concrete, quantitative, interpersonal, and verbal content influences the development of ability patterns in first grade children. The literature related to theoretical models of intellectual development indicates that abilities develop in response to experiential variables, such as…

This study investigated the relationship between measures of speed of cognitive information processing and intelligence test scores. Cognitive processing measures were significantly related to IQ scores. Reaction time tests measure cognitive operations basic to intelligence, and individual differences in intelligence are partly due to variability…

Interrelationships among IQ, academic achievement, and teacher ratings of pupils' classroom achievement were evaluated in a large sample of children from various racial and socioeconomic backgrounds. A substantial relationship between standardized measures of IQ and achievement was found and was independent of race, but decreased with increasing…

Counselors must recognize that most intelligence tests measure a sample of the childs' intellectual functioning on a variety of tasks rather than innate potential. Intelligence varies depending on personality, development, and environmental influences. (Author/HLM)

Genetic influence was estimated on Wechsler Intelligence Scale for Children subtests from inbreeding depression scores calculated on cousin marriages in Japan (n=1,854 children) and correlated with American Black-White racial differences. The genetic contribution of racial differences in cognitive performance may be more robust than was previously…

Five-year follow-up study examined the predictive validity of the Kaufman Assessment Battery for Children (K-ABC) for 39 children identified during preschool as exhibiting language impairment (n=10), behavior control deficits (n=13), or normal language and behavioral development (n=16). Results generally supported the predictive validity of the…

Drawing tests are often used to provide confirmatory and supporting evidence of intelligence or intellectual functioning. The relationship between scores on these types of instruments and academic achievement was studied among graduate students seeking degrees in education. The sample consisted of 125 graduate students in education (93 women and…

This study investigated correlations between the Qualitative score of the Porteus Maze Test and age and rates of recidivism of correctional institution inmates. In addition, the study was structured to provide answers to the following questions: (1) Is there a relationship between age and rates of recidivism and the Conformity-Variability score of…

This study sought to test by the validation process the finding that there is a different relationship between associative learning ability and IQ in middle- and low-socioeconomic groups as reported by Jensen and others. The study was conducted to ascertain need for revision of testing programs and curricular materials used with disadvantaged…

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…

Reports study which compared the value of Piagetian tasks--seriation, conservation and multiple classification--to that of traditional intelligence tests--Cattell and PMA 5 to 7 subtests--as predictors of number language, simple computation, and verbal arithmetic achievement in 312 children from kindergarten to grade 4. Fifty references are…

Reviews findings on the predictive validity of psychometric tests of intelligence. Concludes that conventional tests of intelligence can be useful but only if they are interpreted very carefully, taking into account the factors that can affect them, and in conjunction with other measures. (Author)

Regression lines for the prediction of Wide Range Achievement Test (WRAT) scores by Wechsler Intelligence Scale for Children (WISC) and WISC Revised (WISC-R) intelligence quotients were compared across race, by the Potoff technique. Subjects were 36 black and 30 white children who were referred for psychological evaluation because of learning or…

The diagnosis of children as learning disabled (LD) has become an increasingly popular diagnostic rubric, but the operational definition of "learning disabled" remains a vague, ill-defined construct which is based upon diagnosis by exclusion of other obvious causes. Diagnostic test results and cultural and familial information taken from case…
