Much of our thinking about contemporary social problems reflects tacit presuppositions regarding the operation of heredity and environment in human behavior. These beliefs have important implications for practical decisions. Advances in genetics, psychology, anthropology, and other disciplines have contributed much to a clarification of the…

This study attempted to answer the following questions. Do differences in academic achievement, grade level, sex, and race influence peer perceptions of black and white students as satisfiers of needs achievement recognition and succorance? Can interracial peer acceptance be predicted from intelligence, academic achievement, attendance, age, sex,…

This book on the genetic and environmental influences on intelligence is comprised of the following papers: "The Structure of Intelligence in Relation to the Nature-Nurture Controversy," R. B. Cattell; "Theory of Intelligence," L. G. Humphreys; "Using Measured Intelligence Intelligently," P. R. Merrifield; "Intelligence: Definition, Theory, and…

The rod and frame performance of 70 children, 5 to 7 years of age, with respect to sex and age differences, reliability, and its relationship to general intelligence, was investigated. The rod and frame test was administered individually and again following a period of 35 to 69 days, at which time the Lorge Thorndike Intelligence Test, form 1A,…

This study examines cultural bias in the Wechsler Intelligence Scale for Children. Results indicated no evidence of specific factors peculiar to Blacks v Whites, and rank order of item difficulties was similar in both groups. Race differences were due to differences in mental maturity rather than to test bias. (Author/RD)

This paper reports a study of conformity reactions of white and black children to the unanimous and incorrect judgment of children from either their own or other ethnic groups. Experimental groups comprised four subjects of the same sex and grade level. Groups representing all Negro were used; all variables were completely crossed. The subjects…

To investigate the interrelationships between creativity and seven variables, 74 students in grades 4 through 8 plus the vocational group at a school for the deaf were tested. In addition to creativity, subjects were tested for intelligence, academic achievement, imaginative productions, perception by teachers, self-evaluation career aspirations,…

Problem solving flexibility (PSF), an ability commonly assessed in creativity batteries, was studied in a sample of middle class children (grades 1 through 3, average IQ 114), tested on questions resembling Guilford's consequences procedure. An hypothesis linking PSF with alertness to and interest in the environment was generally supported, more…

IN THE LONGITUDINAL BERKELEY GROWTH STUDY, SUBJECTS WERE TESTED AT 16, 18, 21, AND 26 YEARS ON THE WECHSLER-BELLEVUE, AND AT 36 YEARS ON THE WECHSLER ADULT INTELLIGENCE SCALE, WHICH CONTAIN BOTH VERBAL AND NON-VERBAL SUBSCALES. THE MOST CONSISTENT INCREASES IN MEAN SCORES OVER THE PERIOD WERE IN INFORMATION, VOCABULARY, AND COMPREHENSION. DIGIT…

INFLUENCES WHICH HIGH SCHOOL SENIORS PERCEIVE AS AFFECTING THEIR OCCUPATIONAL AND EDUCATIONAL ASPIRATIONS WERE INVESTIGATED. GROUP-ADMINISTERED INTERVIEW SCHEDULES WERE COMPLETED BY 1,068 SENIORS IN 12 HIGH SCHOOLS BASICALLY ATTENDED BY WHITE STUDENTS AND 11 HIGH SCHOOLS PREDOMINANTLY ATTENDED BY NEGRO STUDENTS. DIFFERENCES IN PERCEPTIONS WERE…

To assess the relationship between paternal behavior and the intellectual functioning of preschool boys and girls, 180 white fathers from middle, working, and lower classes (as defined by the Hollingshead-Redlich Scale) were observed at home interacting with their 4-year-olds (99 boys and 81 girls). Sessions were tape-recorded. The number of…

This paper deals with the issue of black-white differences in cognitive skills. Some authorities attribute these differences to differences in the environments of black and white homes. Others state that the differences are due to differences in genes, i.e., heredity. Scholars holding these two opposing views have become more or less entangled in…

Confirmatory Factor Analysis was used to test first- and second-order factor models on cognitive abilities and their invariance across male and female samples. Subjects were a stratified random sample of 234 male and 225 female 15-year-old students in Singapore attending Secondary 3 (the equivalent of grade 9). Four first-order factors were found…

Results of seventh-grade students taking Scholastic Aptitude Test indicate that, by age 13, a large sex difference in mathematical reasoning ability exists; among students scoring greater than 700, boys outnumbered girls 13 to 1. Hypothesized factors thought to influence the difference (such as course taking, attitudes) were not supported by data…

R. J. Sternberg and others found that the types of behaviors reported by laypersons as characterizing different types of intelligence varied across the different groups tested, and that a person's concept of intelligence affects the manner in which he or she evaluates the intelligence of others. Two experiments by Sternberg et al. were replicated.…
