A causal-comparative study was conducted among 56 educationally disadvantaged children to determine if children who had the benefit of a home-based experience were significantly different from their peers in intellectual ability, self-concept, and cognitive style. Using the cognitive-developmental method of instruction, trained para-professionals…

The cognitive determinants of number series completion performance were studied by presenting a systematic set of problems to adults and to children of high and average intelligence, grades 4 and 5. Pearson correlations between these problems and the number series on the Cognitive Abilities Test were .51, .78 and .43 for the average intelligence,…

Implications are discussed for new instrument development by way of a methodological study which used a task allowing one to focus upon: (1) a non-verbal approach; (2) memory functions; (3) a variety of mnemonics that children use in information retrieval; and (4) a non-traditional procedure supported by psychological and developmental research. A…

The effects of educational stimulation on creative thinking ability and the relationships among verbal and figural creativity, intelligence, and school readiness were investigated in a sample of 123 first grade children. The educational stimulation consisted of special advanced instruction in physical education, music, art, social studies, and…

Four alternative theoretical models of intellectual competence were assessed, using confirmatory factor analysis to account for the correlation patterns derived from Wechsler intelligence tests. It was argued that the difference between the chi-square goodness of fit statistics that are provided when using confirmatory factor analysis gives a…

This study seeks to determine the degree to which certain behavioral measures interact with intelligence, whether in a linear or curvilinear fashion, to help one predict academic achievement in Head Start children to a greater degree than would be possible were intelligence test performance alone used as the predictor variable. Children were…

This booklet cites evidence indicating that intelligence can be trained, given a physiologically normal student and an intensely persistant tutor. Methodologies for increasing mental efficiency have in common the principle of coordination of physical and mental processes, whether achieved by simple relaxation training, brain polarization, or…

The present investigation examined the ability of the Inventory of Home Stimulation (STIM) to predict changes in relative mental test performance of children between 6 months old and 36 months of age. The six STIM subscales were used in discriminant analysis to classify infants into three groups (gainers, stable, losers) in terms of their change…

An investigation was designed to ascertain the effects of cultural background on selected intelligence tests and to identify instruments which validly measure intellectual ability with a minimum of cultural bias. A battery of tests, selected for factor analytic study, was administered and replicated at four grade levels to a sample of Metis and…

This study examined the effects of teacher expectancy on changes in intelligence, known as the phenomenon of the self-fulfilling prophecy. Differences in sex, socioeconomic status, and teacher opinion about standardized tests were control factors. The teachers completed a questionnaire that provided the basis for classifying teachers into high,…

The long-term stability of verbal and nonverbal IQ scores was studied for 146 Spanish-surname students. About 30-50% of Spanish students do no speak English when they begin school. The California Test of Mental Maturity or the Lorge-Thorndike Intelligence Tests were administered in grades 1,2,4,7,9, and 11. The stability of IQ scores for…

Defining intelligence as "current behavioral repertoire that is highly symbolic and abstract," the author relates it to the classroom management problem of tracking, including the method itself, the effect of group membership on intelligence levels, and the change of individuals' IQ levels over time.

The Kaufman Assessment Battery for Children (K-ABC) and the Wechsler Intelligence for Children-Revised (WISC-R) were compared with respect to the magnitudes of the average White-Black differences in standardized scaled scores and in raw scores. Subjects were 172 fourth- and fifth-grade children matched in Black-White pairs. (Author/LMO)

Whether "psychometric" and "Piagetian" kinds of intelligence are similar is a question of whether they have similar courses of development with age. When using factor analysis to address this issue, age effects must be eliminated in order to assess relations among measured constructs. Reanalyses of previous results were…

Discusses how human differences alter results of intelligence tests from industrialized nations to nonindustrialized nations. Intelligence testing research in Africa is reviewed. (Author/DB)
