Elementary children (n=112) comprising average IQ, high IQ, dyslexic, and normal readers were administered measures of planning, attention-arousal, simultaneous and successive processing, phonemic segmentation, and nonverbal IQ. Cognitive tasks differentiating dyslexic from normal readers were the successive processing tasks and two tasks of…

A reanalysis of data from three previously published studies on whether creativity is content general or content specific suggest that, contrary to the results of recent research, a content-general factor may explain 40-50% of the variance in creativity checklist scores. Results are analyzed in light of other studies. (Author/CR)

Using cluster analysis, a study empirically divided 54 children with attention-deficit/hyperactivity disorder (ADHD) based on their Full Scale IQ and reading ability. Clusters had different patterns of cognitive, behavioral, and neurochemical functions, as determined by discrepancies in Verbal-Performance IQ, academic achievement, parent…

Examined were the effects of chronological age and mental age on the understanding of logical rules by four subject groups (10- to 14-years-old): 10 average IQ Ss, 10 learning disabled Ss, 10 older educable retarded Ss and 10 younger educable retarded Ss. (Author/CL)

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,…

This paper attempts to clarify some of the issues raised in the author's earlier paper, "A Theoretical Perspective on the Relationship between Bilingualism and Thought" (Working Papers on Bilingualism, No. 1), as a response to Gerald Neufeld's critique, which appeared in No. 2 of the same series. The present paper argues that Neufeld mistakenly…

Borkowski and Krause (1983) concluded that the locus of black-white intelligence differences lies in metaprocesses not elementary cognitive processes. However, some variables were difference scores with unacceptably low reliability. Magnitude comparisons of racial differences give a different picture of results; comparable differences in measures…

Children, below- and above-average intelligence, were administered tasks involving matching information between auditory/visual modalities and temporal/spatial presentations. The below-average group made more errors and matching problems were not particular to one modality. Factor analyses did suggest that matching processes varied with level of…

Reviews relationship of IQ scores to race and gender. Explores the logic that supports the use of intelligence testing to discriminate and to exclude. Argues that default assumptions allow researchers to remain unaware of the subtle adverse impact of their research. Includes recommendations to encourage a broader understanding of intelligence.…

Inspection time (IT) and Peabody Picture Vocabulary Test (PPVT) scores from 75 school children aged 6-13 years in 2001 were compared with the performances of 70 children aged 6-13 years who had attended the same primary school in 1981 ["J. Exp. Child Psychol." 40 (1985) 1.]. ITs for the 2001 sample were measured with the same four-field…

Jensen (1985) caused us to reexamine earlier findings. After correcting perceptual efficiency and executive systems measures for unreliability, original conclusions remain tenable. Control processes are factors in understanding race-related differences in intelligence. We do not deny the association of "speediness" but argue for a multidimensional…

Young adults with (n=34) and without (n=41) mental retardation completed a sequence-learning and identification task. For some, sequences were constructed following an artificial grammar. Explicit learning was determined by ability to learn and identify random sequences, implicit learning by the tendency to identify incorrectly new grammatical…

Reading comprehension scores from the Wechsler Individual Achievement Tests, the Gates-MacGinitie Reading Test, and the Gray Oral Reading Test were examined in relation to measures of reading, language, and other cognitive skills that have been hypothesized to contribute to comprehension and account for comprehension differences. In a sample of 97…

This study was conducted to determine how the pattern of learning on an abstract concept, plate tectonics, differed between groups of different cognitive levels, sex, and intelligence quotient (IQ). The intensive time-series design was used to examine the achievement of eighth grade and ninth grade earth science students. The unique characteristic…

PRELIMINARY ANALYSES WERE UNDERTAKEN TO DETERMINE THE POTENTIAL CONTRIBUTION OF MOTION PICTURE FILMS TO FACTOR ANALYTIC STUDIES OF HUMAN INTELLECT. OF PRIMARY CONCERN WERE THE OPERATIONS OF COGNITION AND MEMORY, FORMING TWO OF THE FIVE OPERATION COLUMNS OF GUILFORD'S "STRUCTURE OF INTELLECT." THE CORE REFERENCE FOR THE STUDY WAS DEFINED…
