An entire elementary school system with 60 percent white and 40 percent black children was given several ability tests administered by 12 white and eight black examiners. The tests measured verbal and nonverbal IQ, perceptual-motor cognitive development, "speed and persistence" under neutral and motivating instructions, listening attention, and…

Two tests of cognitive development, the Cartoon Conservation Scales, Levels I and II, were designed to measure Piagetian stage-related constructs for children of different age groups. The tests were factor analyzed within age levels and were also analyzed using scalogram and tabular methods to test sequential hypotheses. (Author/CTM)

This report discusses the relationship between bilingualism and mental development of bilingual children. After a review of the relevant literature, a specific study is described. The linguistic background of 648 children from 29 schools, age 10 through 12 inclusive, was measured with the Welsh Linguistic Background Scale. General intelligence was…

The purpose of this project was to administer the Motor Encoding Subtest of the Illinois Test of Psycholinguistic Abilities (IPTA) to a population of 50 American Indian students, and compare their scores with the established norms of the ITPA. Indian students with chronological ages 5-9 enrolled in the first 4 grades at the Fort Thompson…

This study of 34 bilingual Spanish/English children (ages 9-13) revealed the influence of a codeswitching or language mixing factor in performance on the Test de Vocabulario en Imagenes Peabody-Adaptacion Hispanoamericana, Peabody Picture Vocabulary Test-Revised, their translations, and the combined results. Both combined/bilingual instruments'…

A study was conducted to: (1) provide normative data for the Brozovich-Hall Watson (BHW) scale, a non-verbal method of assessing cognitive style; (2) provide data for itwm revision and further refinement of the BHW; and (3) assess the effects of grade level (age), sex and socioeconomic status on cognitive style. The BHW was administered to 621…

The TAMA was designed specifically for the Longitudinal Study as a nonverbal test of general knowledge. The test requires the child to point to the correct picture among three alternatives in response to a question. The two practice items and 25 test items are printed on bound cards, mostly in black and white. Items can be classified as follows:…

This summarizes a study designed to provide a basis for researchers who study measurable areas of human performance or attempt to conceptualize and develop a theory and structure of abilities. Specifically, this study was directed toward the identification of tests that can serve as markers for well established cognitive factors. (Author/CTM)

In order to determine the differential ability of mildly retarded school children to profit from coaching on non-verbal, non-academic reasoning problems and to study their problem solving and conceptual behavior, the Raven Coloured Progressive Matrices Test was given to 72 educable students (IQ 55 to 80) in socioeconomically homogeneous suburban…

The present study examines a new battery of nonverbal cognitive measures used extensively with numerous preschool children. Seven nonverbal, individually administered measures of fluid reasoning and visualization were administered to these children. Raw scores were converted to age-corrected scaled scores and subjected to multivariate analysis of…

Thirty-five tests which measure cognitive abilities at the intermediate grade level and the related manual are intended to accompany the authors' 1973 monograph, "A Structure of Concept Attainment Abilities." Additional tests which measure these abilities (verbal, induction, memory, spatial, numerical, perceptual speed, evaluation, word fluency,…
