Measurements derived from reaction time, movement time, and an index of neural adaptability derived from averaged evoked potentials are significantly related to each other as well as to g factor scores extracted from a battery of 15 psychometric tests in a sample of 54 severely retarded adults.

Compared alternate forms of the Peabody Picture Vocabulary Test-Revised for (N=72) preschool children. Results indicated differences between Form L and Form M mean scores were nonsignificant for Whites, males, females, and the total group. For Black preschoolers, Form L was apparently more difficult to complete successfully than Form M. (Author)

A reanalysis of Stephens' intercorrelations of Wechsler subtests, achievement tests, and Piagetian tasks was conducted. (EJ 055 112) Piagetian tasks contributed almost equally to the definition of the general factor in intelligence along with the Wechsler subtests and the achievement tests. Communality outweighed differences between intelligence…

Reports data on the predictive utility of the WISC-R factor scores for Native American Navajos and examines the diagnostic utility of the FD scores as a correlate of academic achievement. Results indicate limited utility of the WISC-R factor scores in predicting academic achievement for Native American Navajos. (Author/RC)

The McCarthy Scales of Children's Abilities (MSCA) General Cognitive Index provides a good measure of cognitive ability of exceptional children. The verbal and motor scales also seem valid. Interpretation of remaining scales should be made cautiously as scales may not accurately measure abilities of exceptional children. (Author/JAC)

The Wechsler Intelligence Scale for Children-Revised (WISC-R) Comprehension, Arithmetic, and Object Assembly and McCarthy Quantitative and Memory Indices were most sensitive to learning disabled students' achievement. Conversely, the WISC-R Similarities and Arithmetic and the McCarthy Verbal Index were most sensitive to achievement of nonlearning…

Studies the effectiveness of the Miller Analogies Test and undergraduate grade point average in predicting success of military graduate students in on-base programs. Though neither seemed to be valid predictors, they should not be discarded without further study. (JAC)

Studied 72 children for whom the following data were available: IQ score on a conventional test (WISC or Stanford-Binet); Goodenough-Harris drawing test IQ score; and behavior description by the test administrator. Personality traits of children who performed better on either the graphic or conventional IQ test were assessed. (SJL)

Under realistic individual testing conditions there is consistency between the factor structure of the Wechsler Intelligence Scale for Children-Revised (WISC-R) with Anglo and bilingual Mexican American children. This investigation failed to indicate any unfairness to the Mexican American child on the WISC-R. (Author)

This article examines the potential contribution of latent trait models to the study of intelligence. Nontechnical introductions to both unidimensional and multidimensional latent trait models are given. Multidimensional latent trait models can be used to test alternative multiple component theories of test item processing. (Author/CTM)

Performance was better for children above six years of age and better in Spanish than English. It is suggested that the Peabody Picture Vocabulary Test never be used to assess the general intelligence of Mexican American children, because it likely underestimates their ability. (Author)

A Wherry-Wherry hierarchical factor solution was obtained on the Wechsler Adult Intelligence Scale (WAIS) subtest performance of 100 adolescent retardates. The hierarchical arrangement of abilities obtained was consistent with Vernon's model of cognitive structure and previous reports. A g-factor and two major group factors were evident.…

An information-processing framework is presented for understanding intelligence. Two levels of processing are discussed: the steps involved in solving a complex intellectual task, and higher-order processes used to decide how to solve the problem. (MH)

Five major trends in the study of intellectual abilities are identified. These suggest that in the future several kinds of tests will be used to measure several kinds of basic processes of intelligence. There will be a corresponding decrease in concern to measure a single attribute of general intelligence. (Author/RD)

The purpose of the study involving 573 third graders was to explicate the relationships between student test performance on standardized intelligence, achievement, and creativity tests and teacher perceptions of these abilities. (Author)
