Two hundred seventy-four boys and girls, aged 7 through 15 years, participated in a test-retest reliability study of the Developmental Tests of Visual-Motor Association. Test-retest correlations for the total group and subjects comprising categories A through D were significant. (Author/SJL)

Reports two studies demonstrating the ability of nonverbal contextual cues to act as retrieval mechanisms for co-occurring language. Suggests that visual contextual cues, such as speech primacy and motor primacy gestures, can access linguistic target information. Motor primacy cues are shown to act as stronger retrieval cues.

The visual short-term cued recall memory of 8-, 12-, and 16-month-olds was assessed in two experiments using an operant indirect delayed-reaction procedure. In each experiment, 12- and 16-month olds performed better than chance, whereas 8-month-old infants did not. (Author/DB)

Outlines teaching methods that emphasize the use of the right hemisphere of the brain. Argues that most productive thinking requires both modes of thinking and that any good elementary science program should include activities designed to develop both modes. (Author/IRT)

Compares communication apprehension (CA) levels of people exposed or not exposed to visualization (a desensitization technique to assist people in coping with CA) after four months and after eight months. Finds that those exposed to visualization reported significantly lower CA levels at the end of both time periods than those not exposed to…

Debate over whether mental images are visual or spatial representations is seen as based on the false premise that they must be one or the other. Visual neurophysiological research and experiments with a brain-damaged patient (impaired visual representations) suggest that mental imagery has distinct visual and spatial representation components.…

Analysis of (n=92) university students' construction of visual representations (Venn diagrams) of eight set expressions found competent and error-prone students constructed and used procedures to complete set translation tasks, and two-thirds of observed errors arose from consistent implementation of ill-formed procedures. (Author/MKR)

Structures of multiple education and knowledge systems can be recreated in maps, in a social cartography where the space of the social map reflects effects of social changes in real space. Such maps allow social research to escape from modernism's positivist restraints, improve comparative educators' understanding of the social milieu, and open…

Benign visual hallucinations ("phantom vision") were examined in 2 studies, involving a total of 443 adventitiously blinded and sight-impaired veterans. In one study, unusual visual events were reported by 38.7 percent, with 30.6 percent reporting complex hallucinations. Causes of the hallucinations and their treatment are discussed.…

Discusses problems in creating indices and thesauri for digital libraries of geo-spatial multimedia content and proposes a scalable method to automatically generate visual thesauri of large collections of geo-spatial media using fuzzy, unsupervised machine-learning techniques. Uses satellite photographs as examples and discusses texture-based…

Explores the development of elementary school students' (n=88) understanding of comparing two datasets through the responses of students in individual interview settings. Strategies observed within the developmental cycles were visual, numerical, or a combination of the two. Contains 26 references. (Author/ASK)

Two psychometric tests measuring mental rotation (MR) and visualization (VZ) were administered to 209 male and 390 female high school seniors. Results clearly indicate that MR is a plausible mediator variable for sex differences in VZ when such differences do exist. Theoretical, methodological, and practical consequences of these results are…

Discusses the use of Web log analysis to help understand user visit patterns to Web sites and describes the use of computer software to generate a variety of interactive visualizations of log data that can be used to explore server data across various dimensions. Explores difficulties of data collection, presentation, and interpretation.…

Explains Visual Information Retrieval Interfaces (VIRI) and examines the effectiveness of a two-dimensional display format compared to a more standard sorted result list. The Visual Information Browsing Environment (VIBE) was modified to investigate the interaction of the verbal and spatial abilities of users, as measured by cognitive factors…

Focuses on difficulties students have in reading images and understanding a particular domain; e.g., optics and color. Concentrates on the extent to which teachers were conscious of such difficulties and what they suggested doing to avoid possible pitfalls. (Author/MM)
