The reaction times, movement times, and final accuracy of hand movements of 6, 8, and 10 year olds that were directed toward visual goals were measured by means of tasks in which direction and amplitude components of movement were required. (RH)

Investigated a prior classification of Wechsler Memory Scale-Revised (WMS-R) subtests into Verbal and Visual categories. Findings from 45 college students found that memory test performance correlated significantly with performance on subtests of Form II of Luria-Nebraska Neuropsychological Battery that measures substrates of particular memory…

Investigates the difference between children's drawings from two- and three-dimensional models, specifically, the influence of color and line, the difference between multicolor and monochrome material, and gender differences. Finds that children's drawings present detailed information about the subject first, then simple proportions, and finally…

Studied infant ability to extract depth information from a three-dimensional structure. Found evidence that 8-month-old infants distinguished between lines indicating edges, and lines indicating markings, and that they are able to use line junctions to perceive line drawings as depicting three-dimensional objects in the picture plane. (Author)

Based on a two-year study of children in a classroom environment, this article focuses on an early period of writing development in which many unconventional punctuation behaviors occur. Describes a range of types of unconventional punctuation and assigns them a common underlying principle, that of using punctuation according to graphic principles…

Presents scientific explanations of primary colors and color mixing, black and white surfaces, the spectrum and the ability of the eye to distinguish color difference, the description of color, and the appearance and optical properties of metals. Contains 16 references. (Author)

Examined degree to which analytic and holistic modes of processing play a role in children's and adults' categorization of faces. Found a developmental trend from analytic to holistic processing and an effect of face inversion with increasing age. Seven-year-olds processed faces comparably to nonfacial visual stimuli, whereas a growing proportion…

Aspects of cognitive processing were evaluated for 462 adolescents followed for 14 years. Adolescents had been exposed prenatally to a broad range of maternal drinking, mostly at "social" levels. Alcohol-related deficits on cognitive tasks were summarized by a speed-accuracy trade-off on the spatial-visual reasoning task. (SLD)

Presents both theoretical and technical bases on which to build a "science of text visualization." The Spatial Paradigm for Information Retrieval and Exploration (SPIRE) text-visualization system, which images information from free-text documents as natural terrains, serves as an example of the "ecological approach" in its visual metaphor, its…

A study compared 11 Italian children (ages 7-11) with nonverbal learning disabilities (NVLD) to 49 controls on four tasks requiring visuospatial working memory and visual imagery. Results found the children with NVLD showed deficits in the use of visuospatial working memory and visual imagery. (Author/CR)

Studied whether patterns of developmental progression in reality monitoring were present in visual and auditory modalities and the role of cross-modal imagery in reality-monitoring tasks. Found scores revealed evidence of developmental progression in both auditory and visual source-monitoring tasks, but no effect of cross-modal imagery. (Author)

Assessed development of infants' sensitivity to two nested amodal temporal relations in audible and visible events. Found that sensitivity to synchrony was present by 4 weeks, remaining stable across age. Sensitivity to composition emerged by 7 weeks, increasing dramatically with age. Noted pattern of increasing specificity in perception…

Examined role of phonological awareness and visual-orthographic skills in Chinese reading acquisition among first, second, third, and fifth graders who had learned the Hanyu Pinyin script. Found that visual skills predicted reading success at lower grades; pinyin knowledge and ability to discriminate homophonic characters predicted reading success…

Examined two aspects of the specificity of practice hypothesis using a tracking task. In one experiment, visual or auditory feedback about performance was provided. In a second experiment, visual and auditory information were combined. Both experiments supported the specificity of practice hypothesis. Instructing participants to attend to one…

Focuses on the author's "semiotic self" by presenting questions and reflections. Discusses the overlapping groups to which one's multiple "selves" belong. Explains that these groups consist of people who share vocabulary, rituals, and understandings. (CMK)
