The longitudinal study examined the dropout rate of a group of Chicano students who were registered 7th graders in the Tooele School District in the 1967-68 school year. If these students made normal progress, they graduated from high school at the end of the 1972-73 school year. All Spanish-surname students found on the 7th grade rosters of…

This paper discusses research exploring the performance factors involved in studies which test for formal operations. It is suggested that several previous studies dealing with formal operations confound performance and competence in determining the extent of subjects' formal operations schemata. Factors which might account for performance…

This paper reviews studies in which scores on Piagetian tests of logical thought were correlated with IQ, mental age (MA) and chronological age (CA), and examines the possible effects of the size of the age range and mean age of subjects on these correlations. The data included 44 groups of subjects obtained from 36 studies in which Piagetian and…

The book under review deals with models which identify and measure factors determining a man's educational, income, and occupational attainments. The factors include parental background, number of siblings, national origin, race, intelligence, aspirations, motivations, peer group influences, schools, the influence of wife's characteristics, first…

Selected elements of reading and psychomotor characteristics among good and poor readers of divergent intellectual abilities were investigated. Four groups were selected for study: good and poor readers who were of average ability, and good and poor readers who were mentally handicapped. Approximately 160 subjects were identified for testing, and…

The academic careers of three groups of children were followed from grade 1 to grade 12 to determine the effectiveness of early school admission criteria. Children with chronological ages of less than 5 years, 7 months could qualify for early admission into first grade if they achieved a mental age of six years on the Stanford Binet, Form L. Group…

In an effort to isolate the emergence and causes of social class differences in intellectual performance, this longitudinal study was undertaken as a follow-up on a cross-sectional study that yielded no social class differences on the Cattell Infant Intelligence Scale for 12-, 18-, and 24-month-old black children. In the present study, 89 children…

This study investigates the effect of socio-economic level (lower and upper-middle), race (black and white), and sex on locus of control of reinforcement scores, and the relationship between the latter scores and reading achievement in a sample of 211 second grade children. A stratified random sampling technique insured adequate levels of each…

The issue of multiple-choice (MC) vs. created-response (CR) test-item formats was reexamined at the eighth-grade level in three subject areas: general science, American history, and arithmetic. In each subject area, alternate forms with the same item-content but differing in which items were in which format were prepared from standardized tests.…

Arthur R. Jensen's article presented no new data: it only reorganized a biased sample of already existent data. Nevertheless, it has been taken by opponents of school integration as definitive scientific evidence of the innate inequality of black and white students. Jensen and Van Den Haag advocate additional studies on individual learning ability…

Two studies are reported. The first is based on Piaget's assertion that the child's representation of his world is dependent on the level of cognitive development at which he is currently functioning. Forty-eight normals and 48 retardates were given a visual memory task. They were asked to recall a configural presentation in a number of ways,…

This collection of essays about intelligence stems from the revived nature-nurture controversy about the origins of mental abilities, led notably by Arthur Jensen, whose article in 1969 created a furore in the U.S.A., and more lately by H. J. Eysenck in Britain. In planning this book, an attempt has been made to step back from the debate itself…

The results and interpretation of three years of research into inequality are presented in this book. Chapters cover these topics: (1) from equal opportunity to equal results; (2) inequality in the schools--access to schools and colleges, expenditure differences between schools and individuals, access to privileged school mates, and access to fast…

This book is organized in nine parts, as follows. Part I, "Preface," includes an account of how the author went from the rather esoteric research on theoretical problems in serial rote learning to research on the inheritance of mental abilities and its implications for education. Part II, "How Much Can We Boost IQ and Scholastic Achievement?," is…

This illustrated booklet describes research procedures in the Infant Laboratory of the Educational Testing Service to investigate measurable factors in infant behavior which can predict intellectual potential. The research is currently focusing on attending, the manner in which infants respond to various stimuli presented to them during their…
