A model-fitting analysis of the covariance structure of an intelligence quotient (IQ) data set is reported using a model that considers additive and nonadditive genetic parameters and shared and nonshared environment parameters that permit different estimates for different types of relatives. The use of LISREL for such purposes is reviewed. (SLD)

Response to "The Bell Curve." Argues that correlations between IQ and U.S. social problems are created by the IQ selection process; in addition, emphasis on testing and innate abilities has produced lowered expectations of what students can achieve through hard work and learning, resulting in lower mathematics achievement among North…

Cognitive processes in the Raven Progressive Matrices Test, a nonverbal test of analytic intelligence, are analyzed in terms of processes distinguishing between high- and low-scoring students and processes common to all subjects and test items. Two experiments with 89 college students identify the abilities distinguishing among individuals. (SLD)

The stability of some dimensions of ability between the ages of 12 and 15 years was investigated for 225 boys and 242 girls in Sweden. Testing in grades 6, 8, and 9 indicated high stability for the general intelligence factor and for the residual of the General Visual factor. (SLD)

Using the Mayo Older Americans Normative Studies (MOANS) group (526 55-to 97-year-old adults), factor models were examined for the Wechsler Adult Intelligence Scale-Revised (WAIS-R); the Wechsler Memory Scale (WMS); and a core battery of the WAIS-R, the WMS, and the Rey Auditory-Verbal Learning Test. (SLD)

This paper examines the impact of the court decision in Larry P. versus Riles, which declared that intelligence tests are biased and banned the overrepresentation of African-American children in educable mentally retarded programs. The paper discusses the educational situation of these children, now served in regular programs, and examines…

Analysis of scores of 118 visually impaired children on the Wechsler Intelligence Scale for Children (Revised) and the Wechsler Preschool and Primary Scales of Intelligence (Revised) found a consistent response pattern suggesting that the verbal as well as the performance tests provide useful assessment information. (Author/DB)

Reviews the literature on (1) the nature of intelligence; (2) controversy over the use of standardized intelligence tests with cultural minority groups; (3) arguments surrounding intelligence testing of Canadian Native students; (4) language barriers in standardized intelligence testing; and (5) the effects of self-concept and parent educational…

Study investigated relative merits of using teacher judgment and Slosson Full-Range Intelligence Test (SFRIT) to estimate students' math and reading achievement. Analyses of students enrolled in a remedial-reading program, showed that the SFRIT recovered more variance from the distributions of math and reading tests than did teacher judgment. (RJM)

The Wechsler Adult Intelligence Scale-Revised (WAIS-R) and the Cognitive Test for the Blind were used to compare verbal and nonverbal abstraction ability of adults who became blind before age 2 or after age 5 (when expressive language would have been developed). No significant differences were found, but variability of scores on the WAIS-R…

A study involving 257 Navajo and Mexican-American elementary students investigated the internal structure of the DISCOVER assessment, a performance-based assessment grounded in Gardner's theory of multiple intelligence. Results showed low interrating correlations among the five assessment activities, indicating students gifted in one intelligence…

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)

Presents a critical appraisal of Herrnstein and Murray's "The Bell Curve" (1994) and of its analyses of social class, ethnic differences, and public policy proposals. It refutes as cultural superstition the book's theories on the role of intelligence in the social stratification of postindustrial America and the effects of IQ on social…

Data from 30 national service centers found the number of assessment instruments endorsed increased as centers adopted a multidisciplinary approach to education and treatment, the largest proportion of instruments fell within intellectual, motor, and language/communication domains, and instruments were used most frequently for diagnostic and…

This study examined the construct validity of the Comprehensive Test of Nonverbal Intelligence (CTONI) in two separate investigations. The first study examined criterion-related evidence of validity across racial/ethnic groups on the CTONI and the Woodcock-Johnson Psychoeducational Tests of Achievement (3rd edition). The second study examined the…
