Examines the relationship of achievement in reading, spelling, and arithmetic with a variety of other measures, including tests of visual memory and visual-motor association. Concludes that visual association is more closely related to achievement in reading, arithmetic, and spelling than is visual memory. (HOD)

A study involving 66 sixth-graders with learning disabilities, average achievers, and gifted students found gifted students used significantly more visual-spatial representations than the other two groups in solving mathematical problems. Students with learning disabilities used significantly more pictorial representation than their peers, a…

This study examined the arithmetic calculation abilities of kindergarten and first-grade children (n=108) with different patterns of cognitive functioning: low language, low spatial ability, general delays, and nonimpaired. Nonverbal, story, and number fact problems were differentially sensitive to variation in cognitive ability. (Author/JDD)

This article discusses the strengths of gifted visual-spatial learners and their struggles with simple concepts. Strategies for teaching visual-spatial learners are provided including general strategies, strategies for making material more meaningful, ways to help such students during lectures, foreign language strategies, math strategies, and…

The nature of the message used by children, 4 1/2 and 6 1/2 year-old, was studied in a spatial description task. Speaker and listener were separated from one another by an opaque screen, and had to exchange information. Speaker were asked to describe a board showing eight objects placed in a room, and listeners were instructed to draw a similar…

A collection of essays on the comprehension of text brings together perspectives of different disciplines on discourse. Articles include: "Naturalistic Texts and Naturalistic Tasks" (Herre van Oostendorp, Rolf A. Zwaan); "Psychological Studies of Naturalistic Text" (Arthur C. Graesser, Joseph P. Magliano, Karl Haberlandt);…

Research on hemispheric specialization indicates that the two hemispheres of the brain are specialized to perform different functions. A visual style of thinking is associated with the right hemisphere, while a verbal style is associated with the left hemisphere. The possibility of a relationship between psychological androgyny and sex role…

Current studies of cognition emphasize the contrast between two approaches to analysis of individual differences. It is concluded that the cognitive components approach incorporates the cognitive correlates approach, avoids the inadequacy of correlational methods, and models individual differences on various dimensions of cognitive functioning.…

Five- to six-year-old children estimated the size of Euclidian objects using an addition rule of Height plus Width, rather than a multiplying rule. Within the framework of information integration theory, tested whether intensive handling of objects would facilitate shift from addition rule to multiplication rule. Found that following handling,…

Cognitive clusters from the Woodcock-Johnson III (WJ III) Tests of Cognitive Abilities that measure select Cattell-Horn-Carroll broad and narrow cognitive abilities were shown to be significantly related to mathematics achievement in a large, nationally representative sample of children and adolescents. Multiple regression analyses were used to…

Hierarchically organized knowledge about actions has been postulated to explain planning in problem solving. Perdix, a simulation of problem solving in geometry with schematic planning knowledge, is described. Perdix' planning knowledge enables it to augment the problem space it is given by constructing auxiliary lines. The planning system also…

This study demonstrated an aptitude-strategy interaction in linear syllogistic reasoning; specifically, that the efficiency of each of four alternative strategies for solving linear syllogisms would depend on subjects' verbal and spatial abilities. The four strategies, as well as research methods in aptitude-treatment interaction, are discussed.…

Background: Accumulating evidence supports methylphenidate-induced enhancement of neuropsychological functioning in attention deficit hyperactivity disorder (ADHD). The present study was designed to investigate the acute effects of the psychostimulant drug, methylphenidate (MPH), on neuropsychological performance in stimulant naive boys with ADHD.…

This article examines whether various cognitive abilities are associated with symptoms of ADHD. Cognitive ability is conceptualized using Cattell-Horn-Carroll (CHC) theory as measured using the Woodcock-Johnson Tests of Cognitive Ability (3rd ed.). This article also examines whether test session behavior mediates the association between cognitive…

This report presents two experiments that compared the performance of map experts to that of novices. Subjects (from the areas of geography, educational psychology, and sociology) were 13 university faculty members in experiment one and 12 undergraduate students in experiment two. Following a practice trial, the learning of a logical map and a…
