Available for the first time in an English translation, the book reports the results of a series of studies undertaken in the early 1960s on the cognitive development of children with congenital blindness. Chapters one and two review the literaure on such topics as the concept of sensory compensation and the nature of tactual space and provide…

This study examines the Wheatley Cube as a measure of spatial/visualization ability. The Wheatley Cube is a computer managed task which requires the subject to visualize a three-dimensional workspace and to find an invisible dot located within this space. Thirty-three undergraduate students were administered four tests of spatial/imaginal ability…

This series of activities on spatial relationships was designed to help users acquire the skills of spatial visualization and orientation and to improve their effectiveness in applying those skills. The series contains an introduction to spatial orientation with several self-directed activities to help improve that skill. It also contains seven…

To provide converging support that the proper integration of analog and propositional representational systems is associated with spatial ability, the visual, auditory, and bimodal brain event-related potentials were recorded from 50 right-handed Caucasian males. Sensory interaction indices were derived for these subjects who had taken the Surface…

Large-sample item response data for the 10-item Paper Folding worksample 622 (N=2,749) and for five new experimental paper folding items (N=2,514) are analyzed with the logistic item response model and with full-information item factor analysis. The main results of the unidimensional analysis are that: (1) item discrimination is heterogeneous, so…

The significance of spatial factors on an initial segmentation and an active attentional phase was demonstrated by briefly exposing spatial configurations of elements, and then asking the subjects to reproduce the patterns or to search them for a target letter. The stimulus displays consisted of small o's forming different spatial configurations,…

The present study examines interrelations between young children's conceptions of similarity and difference prior to the operational coordination of these relations. A total of 24 preoperational children, 8 each at 3, 4, and 5 years of age, were tested with a classificatory task. Materials included four different geometrical shapes, with four…

Non-conserver children have been shown to progress in a spatial transformation task if the material is socially marked, i.e., when there is a correspondence between the cognitive relations and some social relation (Doise and Mugny, 1981). The present experiment was designed to assess the efficacy of social marking when the social necessity of…

The bibliography lists approximately 150 references (1973-1983) on orientation and mobility for visually impaired individuals. Citations are organized alphabetically by author's name within five major topic areas: general works, manuals and curriculum guides, research literature, mobility for special populations (multiple disabilities, children…

The article describes tasks that promote perceptual motor coordination in handicapped students. An introductory section provides suggestions for implementation and charts the activities in terms of emphasis on visual tracking, visual discrimination and/or copying of forms, spatial body perception, fine motor coordination, tactile discrimination,…

The proposal outlines a study to assess the role of computers in assessing and instructing students with severe cerebral palsy in spatial and communication skills. The computer's capacity to make learning interesting and challenging to the severely disabled student is noted, along with its use as a diagnostic tool. Implications for theories on…

The relationship of lateral awareness and directionality with intellectual ability, academic achievement, and age was investigated with 288 first through third grade elementary school children. With the exception of first graders, Ss were administered three tests: the Lockavitch Test for Lateral Awareness and Directionality (LTLAD), the Short Form…

Discuss seven basic intellectual competencies possessed by all human beings: linguistic, logical-mathematical, musical, spatial, bodily-kinesthetic, interpersonal, and intrapersonal. Because I.Q. tests can measure only the first two qualities, this interview suggests evaluating schools by quality of educational experiences and students by project…

The acquisition of spatial terms in the language development of young children is examined. Two primary theories of word meaning and concept acquisition are reviewed, followed by a summary of current developmental research on spatial terms and factors influencing acquisition. Finally, guidelines for the assessment and teaching of spatial terms are…

Investigated spatial thinking abilities of sixth- and tenth-grade students from two locales--a school on the Navajo reservation and schools in Mesa, Arizona. Overall findings support the contention that there were no substantial time delays or advances in development of selected spatial abilities of Navajo students compared to parallel non-Indian…
