The purpose of the study was to compare the performances of black and white urban high school students on a conventional measure of intelligence, the Lorge Thorndike vocabulary test and a culture specific test, the Black Intelligence Test of Cultural Homogeneity. In addition to determining whether or not there were race differences in performance…

Students of high intellectual ability and their parents were tested on a battery of cognitive tests. Vernon's model of intelligence best fit results. A verbal-educational and a practical-spatial-mechanical factor explained most performance variance. Among children, age related to verbal but not spatial or mechanical abilities. (Author/RD)

A wide array of data was gathered in a nationwide study, including parent and child interviews, intelligence test and achievement test scores, and teacher ratings of children's classroom performance. Results indicated extensive differences favoring intact family children, which persisted when IQ and socioeconomic status measures were controlled.…

Twenty children with attention deficit hyperactivity disorder (ADHD) and low IQs were followed up 4.5 years later (ages 8-20). A majority continued to screen positive for ADHD, as well as display high rates of comorbid anxiety disorders, tics, and elimination disorders. Multiple medication trials resulted in significantly lower hyperactivity…

Longitudinal data on the auditory forward and backward digit span (FDS and BDS) subtests of the Wechsler Intelligence Scale for Children (WISC) were obtained at five age levels (between 6 and 13), in samples of white and black children. Factor analysis and analysis of variance of the data were conducted to test 5 hypotheses, related to Jensen's…

Knowledge of English morphology was studied in intellectually retarded (IQ 50 to 80), normal (IQ 90 to 110), and superior (IQ 120+) children at four chronological age (CA) levels from 4 to 12. The task involved using inflectional and derivational suffixes at two levels of generality: producing inflected and derived forms of English words, and…

A prospective longitudinal investigation related 76 maternal and infant variables to performance on the Metropolitan Readiness Tests (MRT) at age six. The 1,245 study subjects have been followed since birth. Their distribution on measures of intelligence and socioeconomic status is essentially normal. Subjects with high MRT scores were found to…

The major emphasis of this study is on the comparative validities of paired-associate learning tests and IQ tests in predicting reading achievement. The study engages in a brief review of earlier research in order to examine the validity of two assumptions--that the construction and/or the use of a tactic that simplifies a learning task is one of…

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,…

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…

Designed to serve as a reference and resource, this publication contains ideas and information to help teachers modify content and teaching methods to assist students in coping with the changing marketplace. Part 1 of the guide lists educational objectives for these major content areas: (1) The Consumer and the Economy, (2) Values and Goals, (3)…

Retarded subjects were compared with mental- and chronological-age matched controls on serial short-term memory (STM) tasks. Retarded subjects were inferior to the control groups on both primacy and recency items, under two recall conditions. These data are discussed in relation to possible mechanisms underlying IQ-related individual differences…

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…
