General cognitive and specific number abilities that underlay arithmetic performance have been heavily investigated among typically developing students; however, the inquiry has rarely been applied to students with mild intellectual disability (MID). We examined whether domain-general cognitive abilities (i.e. working memory, processing speed, and…

In a randomized-controlled trial we tested a computer-assisted intervention for the prevention of reading difficulties, delivered by nonprofessional tutors, running from kindergarten to halfway Grade 2. The full sample included 123 prereaders (M = 5; 6 years; 56 intervention; 67 controls) with low preliteracy skills. Parents were sent a…

Recent findings from Western developed countries have linked home chaos to children's cognitive performance and behavioral problems. In the present paper we test whether the same pattern of associations can be replicated in a non-Western developing country. Our sample was 203 Pakistani primary school children. To assess home chaos the Confusion,…

The purpose of this concurrent triangulation mixed methods study was to understand the status of succession planning and management (SPM) efforts of the subject university as perceived by the fulltime academic and fulltime administrative staff. Four research questions guided this study: (1) how do fulltime academic staff and fulltime…

Scores on Raven's Progressive Matrices correlated positively with electroencephalogram-recorded alpha rhythm frequency (AF) in 101 healthy male adults, as did one test of verbal ability and one of mental performance. However, AF did not show significant relationships with general intelligence or spatial and arithmetic abilities. (SLD)

THE THREE MAIN PURPOSES OF THIS RESEARCH IN PROBLEM-SOLVING WERE (1) TO EVALUATE GROUP PERFORMANCE VERSUS PERFORMANCE NORMS BASED ON THE PROPERTIES OF THE PROBLEM, (2) TO STUDY INDIVIDUAL PERFORMANCE, AND (3) TO INVESTIGATE THE EFFECT THAT A PARTICULAR EDUCATIONAL LEVEL HAS ON THE PERFORMANCE OF THESE PROBLEMS. THE SUBJECTS USED CONSISTED OF A…

Results of two studies using the Esper paradigm to determine development of rule application and discovery are reported. Subjects learned and generalized when rule and structure were provided, but there was little evidence of rule discovery. Manipulations of memory and attention facilitated learning, but only attention facilitated rule discovery.…

This project examined the hypothesis that different background experiences associated with cultural grouping may lead to differences in test-taking strategies which result in score differences extraneous to the abilities the test is intended to measure. Its purposes were to confirm (or disconfirm) the cultural differences hypothesis and to provide…

A task was developed to differentiate the reasoning of elementary school students in fifth, sixth, and seventh grades. Subjects completed 16 matrices containing two, three, or four dimensions and varying in the embeddedness of the dimensions. They also solved a formal operational task assessing ability to isolate, exclude, and include variables.…

The Raven Coloured Progressive Matrices and a Piagetian battery were administered to a sample of hearing-impaired elementary school children under six different conditions. Results indicated that scores varied as a function of the degree and type of feedback or elaboration. (JKS)

This study investigated the effects of prompting, or directing/controlling attention, during a reasoning task on the performance of 68 children with attention deficit disorders, learning disabilities, or no handicaps, in grades 1-12. All groups benefited from prompting, and prompting was related to a different set of cognitive processes in each…

The relationship of cognitive style variables and conditions of test administration was investigated in cognitive assessments of hearing-impaired children, aged six through eleven. One hundred-twenty children were given the Raven Coloured Progressive Matrices (CPM) and a Piagetian battery under one of six conditions of testing: (1) standard; (2)…
