Wechsler Intelligence Scale for Children, 3rd and 4th editions (WISC-III n = 586 and WISC-IV n = 118), profiles were compared for children with ADHD and normal intelligence. Mean Verbal Comprehension Index (VCI) and Perceptual Organization/Perceptual Reasoning Index (POI/PRI) scores were significantly higher than Freedom From…

The Wechsler Intelligence Scale for Children (WISC) has a long history, dating back to the 1930s, when it was devised specifically for measuring the intelligence of children through verbal and performance subtests. Intelligence quotients (IQs) are developed for verbal and performance skills. The subtests, their factors, indices derived from them,…

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…

The development and standardization of the third edition of the Wechsler Intelligence Scale for Children-Revised (WISC-R) are described. The existence of documented historical trends was a significant factor in the project to revise the WISC-R, which is the most widely used intelligence battery in North America. Development of the third edition…

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)

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)

The first part of this volume is concerned with theoretical and conceptual issues concerning learning potential assessment. The second part deals with methodological and measurement issues in learning potential assessment, and the third part is devoted to research projects and practical applications of learning potential tests. The following…

The use of standardized testing in secondary schools (with students between 10 and 19 years old) is described for four European countries: (1) England; (2) West Germany; (3) the Netherlands; and (4) Sweden. In the decentralized English system, several published standardized tests are available; they are used less at the secondary level than in…

The study examined the process by which diagnostic data on children thought to have learning disabilities (LD) are generated and used. Emphasis was placed on the validity of test instruments in common use in the field. Since part of the practical validity of any instrument used to identify an LD child rests on the validity of the LD construct…

Intelligence quotient (IQ) test performance is reported for 93 families restudied 10 years after the Minnesota Transracial Adoption Study in 1975. Results for 426 subjects support the original finding: being reared in the IQ test culture and prevailing school culture benefits all children's IQ scores and academic achievement. (SLD)

The relevance of intelligence testing for schools within one district, the Sacramento (California) school district and the state of California is explored, and applications of intelligence theory in district schools and classrooms are discussed. Intelligence, for purposes of this discussion, is the aggregate capacity of each student's…

The strongest recent statement that inequality in America is the natural result of a free market came in "The Bell Curve: Intelligence and Class Structure in American Life" by Richard Herrnstein and Charles Murray. These authors argued that intelligence determines how well people do in life, and the rich are rich largely because they are…

This evaluation summarizes progress made in implementing procedures to reduce racial bias in referral, assessment, and placement procedures for special education under a court-mandated desegregation plan in Chicago (Illinois). The Board of Education discontinued the use of intelligence tests in evaluating students for special education and formed…

This discussion focuses on reading problems arising when bilingual children must learn two different scripts, and how the nature of the relationship between the two scripts may influence the child's ability to transfer and develop reading skills. First, models of normal and abnormal reading in English are described. The significance of these…

Three tables are provided to aid in the clinical interpretation of factor scores for the Wechsler Adult Intelligence Scale-Revised (WAIS-R; 1981). The factor structure of the WAIS-R has proven to be robust across samples, tests, time, statistical analyses, measurement scales, and distortions of the distribution. Information necessary to make…
