The main thrust of American education has been cognitively oriented. Recent research on the human brain suggests that such orientation is a general function of only one hemisphere of the brain, the left. Because of the close relationships among speech, language, thinking, reasoning, and the higher mental functions, the left brain hemisphere…

A study designed to test the Piagetian theory that distinct stages in the organization of memory relating to horizontality correspond to successive stages in operative level was conducted with 154 twelve- to fourteen-year-old subjects. Loglinear and path analysis models were used to describe the association between operative level and spatial…

This experiment investigated the effect of children's successive encounters with a large scale environment on their subsequent reconstructions of that environment. Twenty children (10 boys, 10 girls) at each of three grade levels (kindergarten, two, and five) reconstructed from memory the spatial layout of buildings in a large model town. All…

The study of trigonometric functions in terms of the unit circle offer an example of how students can learn algebraic relations and operations while using visually oriented thinking. Illustrations are included. (MNS)

Performance on five logical, spatial, and formal tasks was used to make inferences about the reasoning structures of 101 middle and high school students. Findings (obtained during interviews) include grade level differences in performance and sex differences in performance on one of the tasks. Implications for instruction are proposed. (Author/JN)

Investigated whether examining materials from several perspectives had greater effect on development of projective spatial abilities than examining materials from a single perspective. Results using 105 students (56 females, 49 males) favored the former approach. Also, sex was determined to have no direct effect on development of projective…

This report describes a study that investigated the relationship between mental imagery and problem solving in physics, specifically in kinematics. A distinction is made between visual imagery and spatial imagery used in solving physics problems. The results of this study indicate that while spatial imagery may promote problem solving success, the…

It is suggested that there are three levels of difficulty posing barriers to successful problem-solving performance: (1) entry into the problem; (2) basic skills; and (3) general cognitive skills. The levels are described in some detail and suggestions for instructional methods are given. (MP)

Examined the hypothesis that aging and hemispheric laterality interact to produce relatively greater decrements in older individuals in right hemispheric dominant (visuospatial) than left hemispheric dominant (verbal) tasks in 24 early middle-aged and 24 older males. Data did not support the notion of a laterality effect associated with aging.…

Explores cognitive operations such as coordination, integration, and structuring as manifested in a spatial context. Relates spatial thinking to enumeration strategies. Interviews with 45 third graders and 78 fifth graders suggest that students initially see arrays of cubes as uncoordinated sets of faces, later as space-filling structures. (FDR)

This article introduces the concept of a multi-component working memory. Emphasis is placed on the phonological loop component, its fractionation into a storage and processing component, and implications for native and second language learning. An overview of the visual spatial sketchpad and its possible role in language is provided. (Contains…

Fourteen teenage or young adult males disabled in print acquisition were studied to determine their patterns of verbal and spatial processing. It was found that, at retest a mean of 5.4 years later, the Similarities score significantly increased while the Vocabulary scores and Acquired Knowledge category actually decreased. (Author/DB)

Examines the potential contribution of different neural systems to developmental change in the duration of visual fixation, and the individual differences in that variable that are predictive of subsequent cognitive function. Presents hypotheses concerning two specific and independent neural systems and how they might contribute to individual and…

Twenty-four adults with mild mental retardation were compared with equal-mental age children and adults without mental retardation on tactile processing asymmetries. Results suggest that hemispheric processing is dependent on information processing requirements rather than type of stimulus. (Author/JDD)

A visual orienting task was given to 11 high functioning male adolescents and adults with autism. Findings suggested that autistic people have difficulty processing briefly presented cue information and problems disengaging and shifting attention within the visual modality. Results support previous ideas that attentional dysfunction may underlie…
