The Processing Speed Index (PSI) was first introduced on the Wechsler Intelligence Scale, Third Edition (WISC-III; D. Wechsler, 1991), and little is known about its clinical significance. In a referred sample (N = 980), children with neurological disorders (ADHD, autism, bipolar disorder, and LD) had mean PSI and Freedom from Distractibility Index…

Heavy migration into Canada and migration from Native rural communities to urban areas has made it necessary to identify appropriate instruments for assessing minority children's academic abilities. In Canada, IQ tests have been used extensively for academic placement in school. This paper reviews the literature evaluating cultural bias in IQ…

This paper presents a study regarding the correlation of the Stanford-Binet: 4th Edition Intelligence Quotient (IQ) scores with the Wechsler Adult Intelligence Scale-Revised (WAIS-R) IQ scores for the purpose of improving the identification process for educable mentally handicapped (EMH) school age adolescents and young adults. The sample included…

Findings from the Iowa Assessment Project are examined regarding the assessment and use of information on adaptive behavior and sociocultural background in decisions about students with mild mental retardation. Background aspects reviewed include terminology regarding mild retardation; research, litigation, and legislation on the topic during the…

The importance and consequences of raising the average ability level (IQ) of the population requires consideration of the ability level that society requires, how the relevant abilities are distributed, and the efficiency of the current educational process. Within the framework of these factors, the document discusses the determinants of mental…

The purpose of the study was twofold: first, to determine the reliability of a paired-associate (PA) task when used as a test of learning proficiency; and second, to assess the relationship between performance on the PA task and on IQ tests as a function of grade level (kindergarten, first, third) and socioeconomic status (high, low). The…

Six current issues in the use of tests are examined in this paper. Are the tests used in education valid? In general and to a reasonably satisfactory extent they are. Is the emphasis these tests place on cognitive achievements a serious limitation? Because of the basic and pervasive role of cognition in human affairs, and in the absence of any…

Inner city children have suffered indiscriminately from strict, illogical scoring of standardized IQ tests which do not credit children with thoughtful responses accurately reflecting their experiences and backgrounds. As a result, IQ scores too often doom these children to learning situations for children of lower mentality levels than their own.…

Theories explaining differences in IQ performances between races in terms of (a) genetics and (b) the role of the environment are both criticized. It is argued that the Cultural Distance Approach, which stresses the role of a subculture's distance from the major culture on which IQ questions are based, has the greatest explanatory power. (RDN)

Scores on the Wechsler Intelligence Scale for Children-Revised (WISC-R) and Wechsler Adult Intelligence Scale-Revised (WAIS-R) Verbal, Performance, and Full Scales were compared for 26 adolescents with educable mental handicaps. The WAIS-R, while strongly correlated with the WISC-R, provided higher scores on all three scales. Several WISC-R…

Reviews criticism of Dunn's monograph on Hispanic-Anglo differences in IQ scores. Discusses the heritability and malleability of IQ, the reciprocal relationship between achievement and intelligence, negative effects of schooling for some caste-like minorities, and superior cognitive skills among balanced bilingual students. Contains 19 references.…

The relationship between the Wechsler Intelligence Scale for Children-III (WISC-III) and the Clinical Evaluation of Language Fundamentals-Revised (CELF-R) was investigated in 53 third graders from students in the 15 educational cooperatives across Arkansas. Additional information regarding race, academic achievement, and aptitude was gathered for…

Although British psychologist Francis Galton lost the battle for the definition of intelligence in his own time, his views live on in the work of Richard Herrnstein and Charles Murray. They argue that the Intelligence Quotient (IQ) is an adequate measure of intelligence, and that IQ is highly heritable. They contend that there are racial and…

This very brief paper summarizes 20 major findings of research on 3000 gifted children over 19 years at the Gifted Development Center (Denver, Colorado). Among findings are: (1) there are more highly gifted children than previously recognized; (2) when one child is gifted, the chances are great that all siblings are gifted; (3) second children are…

The tetrad of subtests of the Wechsler Intelligence Scale for Children-Revised (WISC-R) that best predicts the WISC-R Full-Scale intelligence quotient (IQ) was determined for 1,589 Appalachian students referred for evaluation in grades 1-4, 5-8, and 9-10. The sample was divided into three groups. Students in grades 1 through 4 (n=655) were those…
