Eight participants with Asperger syndrome (AS) (ages 10-41) were assessed in the following areas: the pragmatics of language and communication; verbal and visual memory; visual-spatial abilities; and bimanual motor skills. Results confirmed the close similarity in the neuropsychologic profiles of non-verbal learning disabilities syndrome and AS.…

The purpose of this investigation was to evaluate the effectiveness of six instructional programs with the aim of alleviating the problems encountered by students in visualizing rotation in molecular diagrams. Models were filmed rotating around the three different axes with different speeds with and without shadows. (KR)

Examines how architectural forms affect the inner sensual system, presenting several studies looking at the influence of school architecture on student perception and reaction. Describes empirical investigations that attempt to identify how an observer physiologically responds to elements in architectural design. Includes graphs and architectural…

Deals with the issue of visualization as it is related to the learning of mathematics in multicultural classrooms. Discusses the importance and the role of visualization in multicultural classrooms. (YP)

A non-informative cue (C) elicits an inhibition of manual reaction time (MRT) to a visual target (T). We report an experiment to examine if the spatial distribution of this inhibitory effect follows Polar or Cartesian coordinate systems. C appeared at one out of 8 isoeccentric (7[degrees]) positions, the C-T angular distances (in polar…

This exploratory study of the effects of the new visual communications media imagery (e.g., video games, digital television, and computer graphics) on the visual perception process is designed to provide a theoretical framework for research, introduce appropriate research instruments for such study, and experiment with the application of biometric…

Summarizes the anatomical, physiological, and psychological evidence related to the primate visual system. States that comparison of perceptual abilities with the electrophysiological properties of neurons may help deduce functions of visual areas. (RT)

Investigated the relationship between Vividness of Movement Imagery Questionnaire scores and kinesthetic acuity--the sense of body position and movement--among 10- and 14-year-olds. Found that in the older group, those with high levels of visual movement imagery performed better on measures of kinesthetic acuity; no such effect was found for…

Examines predictor variables involved in the performance of 152 male and 143 female gifted high school juniors on the Scholastic Aptitude Test in mathematics (SAT-M). Concludes that males demonstrate greater visual-spatial ability which plays a dominant role in SAT-M performance. (FMW)

Reviews the literature on psychological and educational assessment of American Indian and Alaska Native children, including the background psychological factors of biological deprivation, motivation, attitudes toward self, and traditional nonformal education. Discusses brain hemispheres, visuospatial skills, otitis media, fetal alcohol syndrome,…

The current study explored possible sources of demographic effects through analyses of errors from modified formats of the Benton Visual Retention Test (BVRT) completed by African American elders. Results indicate that: (1) reading level was a stronger predictor of BVRT performance than years of education; (2) on the single-item matching format of…

Cognitive processing limitations restrict the number of complex information items held and processed in human working memory. To overcome such limitations, a verbal working memory channel is used to construct an if-then proposition representation of facts and a visual working memory channel is used to construct a visual imagery of geometric…

The inter-subject/intra-subject subtest patterns (profiles) of the same sample of gifted children were examined based on factors found in a previous study of the Raven Coloured Progressive Matrices Test (CPM) that investigated structural properties with specific application to a sample of gifted children. The sample consisted of 166 children (78…

This study investigated four types of media formats: (1) talking head; (2) voice-under-text; (3) voice-under-video; and (4) multiformat (combination of talking head, voice-under-video, and text). Sixty-four suburban middle-school students were shown four different narrative stories, each presented in a different media format. Students were tested…

Sex differences in cerebral organization and functioning, and the apparent superiority of males in spatial ability are examined in this paper. Attention is given to several kinds of cognitive and perceptual tasks in which sex differences in spatial ability have been shown to exist; among these are tasks involving: (1) recall and detection of…
