The relationship between the manner in which environments are encountered and the nature of environmental features in the construction of spatial representations was examined. It was found that performance of a thematic activity facilitated construction of a spatial representation of a large-scale environment. (PCB)

Comparison for memory for spatial location of 30 persons with and 30 persons without mental retardation found the control group recalled more intentionally learned than incidentally learned locations. The experimental group performed better after incidental learning than after intentional learning and scored as highly as controls on incidental…

Results of two studies suggested that acquisition of route mapping during the preschool years provides a means of organizing spatial information and internal representations necessary for successful problem solving in general. (Author/RH)

Second- and fourth-grade children viewed a cylindrical object in nine positions and identified the 90- , 180- , or 270-degree positions from a set of photographs. Perspectives in which the object differed from the child's view in both left-right and near-far dimensions were more difficult than perspectives that only transformed one dimension.…

Examines the fallacies about the nature of abilities and learning and about the interaction between sense modalities which follow from the dichotomy in relation to explanations of spatial development in the blind. Suggests that interactions between cognitive and perceptual factors need to be considered to explain more adequately effects of sensory…

Discusses the spatial aspects of Greeno's model of conceptual domains and applies the theory to geometry learning. Examines the relationship between mathematical and spatial thinking in light of Greeno's environmental/spatial view of learning. (Contains 16 references.) (MDH)

Varied conditions under which children aged four to five years matched the area of a rectangle with a given width or height to that of a square. Subjects matched one dimension of the rectangle to one side of the square suggesting that area matches seemed to be based on a side-matching strategy. (Author/AS)
