Comparison of 30 children having reading disabilities and average to above-average nonverbal IQ with control children revealed that the average-IQ children with reading disabilities differed from chronological controls, but not reading age controls, mainly in the area of successive processing. Results support the critical role of successive…

Tests causal models of verbal and performance IQ in 69 Mexican-American children of low socioeconomic status. Years of mother's education were correlated with IQ at 3 years and at 6 to 8 years, but traditional/nontraditional attitudes showed conflicting correlations over time. The adequacy of standarized IQ tests for this population is questioned.…

The study with noninstitutionalized organic and familial mentally retarded and borderline mentally retarded children (N=79) at 2 chronological age levels (mean ages 7 and 10) found no age differences in imitation behaviors in the organic low IQ group and more absolute imitation and recall behaviors in familial low IQ children. (Author/DB)

To investigate the factors determining why some children succeed at certain intellectual tasks while others of equal or near equal IQ, age, and motivation are unable to master the same task, 145 female and 144 male eighth grade students were administered "An Inventory of Piaget's Developmental Tasks" (IPDT). Labeled as concrete,…

Two studies examined the relation between current developmental levels, as estimated by IQ, and proximal levels of development, as estimated by the efficiency of learning and transfer in assisted contexts. Subjects were 8- to ll-year-old children. Theoretical and clinical implications are discussed. (HOD)

Reports data on several measures for 160 low income black ninth- and tenth-graders who participated for one year in Bereiter-Engelmann, DARCEE, Montessori, or traditional prekindergarten. Discusses possible relationships between techniques used in different preschool programs and sex differences in achievement level and IQ. (Author/CB)

Examines the mental development scores for two groups of at-risk infants throughout their childhood--those classified as small for gestational age (SGA) and those twins falling below 1,750g birth weight--and determines that SGA twins showed only a modest deficit in IQ scores as compared to the full twin samples. (HOD)

Many variables mitigate against a culture-fair test being devised. The Queensland Test--which has been administered to Aboriginal children--is probably fairer than most IQ tests, although it appears to measure the degree of contact with Western culture (implying socio-economic variables) rather than mental and chronological age or cognitive…

This overview reviews a program of interlinked cross-sectional and longitudinal investigations of the nature of cognitive development in infants and young children with Down's Syndrome. The research falls into three groupings: object concept studies, operant learning experiments, and IQ studies. Early results suggest a common learning style which…

In search of a better understanding of the learning difficulties in basic electricity, learning results, interest, achievement motivation, IQ, and cognitive development were investigated in students from both urban and rural schools. An analysis reveals that, for urban classes, learning is related primarily to interest and motivation and, for…

The Infant Health and Development Program was an eight-site randomized controlled trial of comprehensive early intervention for low birthweight, premature infants from birth to age three. Higher mental development and IQ were associated with high levels of intervention participation at 24 and 36 (but not 12) months. A dose-response relation…

Comparison of children and adolescents with Fragile X Syndrome (n=18) or autism (n=18) for changes in cognitive ability and adaptive behavior over 9 years found steeper decreases in IQ scores among Fragile X subjects with older autistic subjects autism exhibiting stable test-retest scores. Comparative declines in adaptive behavior scores were…

This study investigated the effects of K. J. Klauer's (1989) inductive reasoning training program of teaching children. Effects of training and the range of transfer of the training were assessed. The subjects were 34 third-grade Dutch children of average ability, matched on age, sex, and IQ. Children from the training condition (N=17) received…

The study compared play among five groups of children (ages 3-7 years): normal children (N=41); those diagnosed with language delays (N=241), those with autism but normal intelligence (N=71), those with autism and mental retardation (N=97), and those with nonautistic mental deficiency (N=86). Each child was evaluated using a 25 minute structured…

The decision making processes of children in a probabilistic environment were studied within the context of the theory of signal detection (TSD). The relationship between the age of the child and his ability to revise decision criteria was examined, as well as the appropriateness of TSD measures and methodology with children. It was hypothesized…
