This paper repudiates Jensen's hypothesis that differences in IQ scores and scholastic achievement in Negro and white children are genetically based. Specifically, Jensen's identification of IQ scores as a measure of abstract reasoning and problem solving and of levels of ability, and his evaluation of the magnitude of the genetic component in IQ…

This report examines the Family Cognitive Profile Study which provided for the collection and analysis of data regarding the IQ gains of children enrolled in the Mother Child Home Program (MCHP). The existence of siblings among the subjects of the MCHP was noted by the Verbal Interaction Project (VIP), the research organization responsible for…

The effects of conservation activities on children's acquisition of Piaget's conservation concepts were investigated. One hundred and twenty-eight seven-to nine-year-old children in four classrooms were given pre- and post-evaluation measures of conservation ability. The experimental group completed a set of 42 self-directed conservation…

The purpose of this study was to (1) find if spelling approaches could be isolated and classified by the use of the JDR Spelling Checklist (an interview-type questionnaire); (2) determine the incidence of approach--visual, auditory, kinesthetic, or combination--used by students in spelling new words; (3) see if a relationship existed between the…

Thirty-two Afro-American and 50 Mexican-American seventh graders were randomly selected from a school located in a central Texas low socioeconomic environment. The subjects were administered the New Developmental Reading Tests, The Silent Reading Diagnostic Tests, and The California Short-Form Test of Mental Maturity. When the two groups were…

The controversy over intelligence testing is more often influenced by political considerations than empirical research. A survey of 1,020 experts found that a majority agree that (1) intelligence can be defined; (2) heredity plays a role in individual and group IQ differences; and (3) intelligence testing in schools should continue at its present…

Many variables mitigate against a culture-fair test being devised. The Queensland Test--which has been administered to Aboriginal children--is probably fairer than most IQ tests, although it appears to measure the degree of contact with Western culture (implying socio-economic variables) rather than mental and chronological age or cognitive…

Investigated the academic and intellectual performance of disadvantaged children who had experienced one of four types of prekindergarten program or no prekindergarten at all. IQ measures did not differ significantly among preschool program groups, but differential effects in the three grades, related to both preschool program and sex, were noted…

Korean schoolchildren referred for psychological evaluation because of behavioral/emotional problems were subjected to a battery of tests, and half of the subjects were found to need special placement, while the other half were handicapped only by English-language difficulties. The bilingual evaluation was found useful in planning individual…

Infants judged to be at risk for subnormal intellectual growth were randomly assigned to experimental and control groups which varied as to educational curriculum activities. Two types of evidence, group differences and parent-child IQ correlations, demonstrate the importance of early environments in intellectual development. (Author/RD)

This study evaluated the usefulness of perinatal medical status, environmental risk, and infant developmental status as predictors of low IQ at age 4 among 70 4-year-olds who had been in a neonatal intensive care unit at birth. It found family environment the most predictive, 18-month developmental assessments somewhat useful, and perinatal health…

Describes Iowa's use of the term "mental disability" rather than mental retardation and an IQ cutoff score of 85 for classification of mental disability. Revised draft guidelines for the identification of mental disability are presented that contain four criteria, including an IQ cutoff score of 75. (CR)

Argues that the claims made in defense of IQ tests as measures of innate intelligence are unreasonable and false. Attempts to establish what the views of the vanguard of IQ testers are, their origin, how IQ tests have been applied and what they consist of. Aims to show the incorrectness of those views, uses, and interpretations. (200 references)…

Describes an alternative method of placing students in reading groups which reduces reliance on achievement tests, yet remains manageable enough for large groups of students. Describes the six formal and informal measures used in placement: achievement test scores, IQ scores, attitude scores, current placement, grade in reading, and teacher…
