Experiment One demonstrated that all six- and seven-year-old subjects and many four- and five-year-old preschool children could learn layout of large playhouse of six adjoined rooms by memorizing map. When, in Experiment Two, preschoolers carried map of entire configuration with them around larger room, they performed perfectly or almost…

Evidence is presented negating the theory that gravitoinertial force is perceived. It is suggested that spatial orientation is based on information derived from patterns of motion of the organism, the surface of support, and compensatory actions of the organism. Recommendations for further research are outlined. (SLD)

Three studies examined the hypotheses that: (1) codability and not extent of distance determines difficulty; (2) critical features and not whole objects are coded; and (3) implicit perceptual axes provide a frame of reference for coding the display. Results supporting these hypotheses are discussed in terms of a description of spatial…

Several experiments were undertaken with a total of 111 undergraduates. Subjects attempted to imagine how three-dimensional novel wire objects would appear from viewpoints other than that of the subject. Subjects were unable to perform this task without making use of strategies that circumvent the process of visualization. (TJH)

Examined expressions of spatial knowledge of first-, fourth-, and sixth-grade children who performed model construction, verbal description, and route reversal tasks after mastering a pedestrian maze. Age-related differences were found in rate of learning the maze, and equivalent abilities in sequencing intersections and route reversal. (SAK)

Discusses the notions and language of spatial relations of various cultures, particularly those of deaf students. (MKR)

Eighty-eight children (either totally blind or with residual vision) estimated directions between landmarks in a large scale layout of objects. Children experienced the layout either directly by walking around it or indirectly by examining a tactile map. Use of tactile maps considerably facilitated the performance of the blind children.

In experiments involving 178 and 190 military recruits, spatial, quantitative, and verbal inspection time (IT) and visual search (VS) tasks and an intelligence test were administered. Results indicate that IT performance has a component related to intelligence tests and an independent component related to processing speed tests such as VS. (SLD)

Reports findings from three experiments designed to show how readers inferred spatial information relevant to a story character's movements through a previously memorized layout of a fictional building. Examines how inference measures are related to spatial imagery. (HB)

Two experiments examined the development of recall organization by observing use of categorical and spatial clustering strategies and how encoding experiences and recall task influence degree of organization. Children and adults recalled furniture from their home. Older subjects organized items spatially; when recalling objects and their…

Six types of remedial projection slide programs were tested on male students (n=120) who showed difficulty in visualizing rotation from molecular diagrams. There were no significant differences in improvement of understanding which were dependent on the number of remedial diagrams. However, when slides contained multicolored diagrams, which were…

Argues that map skills instruction is among the broadest skill applications in the elementary school curriculum. Identifies problems encountered by elementary school children in dealing with maps and describes tasks designed to address such problems. Suggests that what teachers and curriculum developers learn from working with students can be used…

Describes a series of exploratory experiments that investigated information professionals' and geographers' use of geographic materials. Mental models used in the manipulation of geographic data are discussed; the improvement of Geographic Information Systems (GIS) is addressed; and Spotlight, a new interactive tool for exploring maps, is…

In four experiments, three, four, and five year olds were successful in solving perspective-taking problems when they were asked what object occupied a specified location with respect to a hypothetical observer. Results indicated developmental change in several important aspects of spatial performance. (BC)

Describes virtual realities as environments in which visual, aural, or other stimuli generate in the mind of the user a sense of navigable, frameless, three-dimensional space, and predicts that the availability of computer technology to create real-time, three-dimensional graphics will bring radical changes in the educational use of visualization…
