The aim of the study was to investigate the relationship between the Flynn effect and the effects of age differences between siblings on the intelligence difference between them. In Norway, the secular trends in intelligence-test score means vary both in magnitude and direction. We identified three periods: one period where the mean intelligence…

Suggests an alternate, and optimistic, interpretation of developmental data that has been interpreted as indicating cumulative deficit in IQ among socioeconomically deprived Black children. (Author/SS)

A study looked for age differences in the quality of responses to the Life Review Task (LRT), studied the LRT itself as a tool for exploring wisdom and intellectual functioning in adulthood, and considered personality characteristics and life experience as alternative predictors of response quality. Sixty-three West German women of different ages…

The author reviews cross-sectional and longitudinal studies on the status of intelligence in the aging, and finds conflicting conclusions: (1) intelligence does decline as persons grow older; (2) only some aspects decline while others improve; and (3) intelligence does not decline. Certain factors are adduced to suggest that such…

Cognitive ability of nondiabetic children and early and late onset diabetic children was compared. Diabetic children scored in the normal range in intelligence and academic performance, but showed evidence of school difficulties and memory deficiencies. Children's perceived self-competence and parents' reports of children's functioning and…

This study of 501 children and adults found that subjects with mental retardation or borderline intelligence were less proficient at identifying facial expressions of emotion than were children of average intelligence. Among individuals with mental retardation or borderline intelligence, recognition increased with intelligence quotient. Among…

The selected bibliography contains about 400 references taken from a keysort file of more than 45,000 references, compiled from commercially available data bases and published sources, relevant to gerontology. Those of questionable accuracy were checked or deleted during the verification process. Most references are in English and were selected…

Twenty high mental age (MA) subjects and 33 low MA subjects who had been in a free word association test 30 months previously were retested with the Moran 80-Word List. At the time of the previous testing, subjects in the high group had a mean chronological age (CA) of 17.1 and mean MA of 11.5; subjects in the low group had a mean CA of 15.3 and…

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…

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,…

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…

The effects of age and intelligence levels upon word associations were studied in 96 intellectually retarded, normal, and superior children with IQ's of 65 to 80, 91 to 110, and 117 to 158 respectively. A word association and a word usage task (reliability coefficients of .91 and .98) called for homogeneous responses to six form classes--count…

This study focuses on the effects of family size and spacing on intellectual, social, and personality development of children. The sample consisted of 533 suburban, middle class, large family (five or more) and small two child family children. The children, 233 boys and 300 girls, were teenagers attending either junior or senior high school.…
