Corman and Escalona's scales for Object Permanence and Spatial Relationships were administered to 98 severely and profoundly retarded children on three occasions, with intervals of six months between successive administrations. The findings demonstrated the high stability of the scales when environmental conditions are themselves highly stable.…

Aims to develop new procedures to collect and analyze data pertaining to spatial development, to explicate a neo-Piagetian model within which these data can be examined, and to assess the validity of this model in tasks requiring perceptual skills and/or rotation (perspective) skills. (RH)

Televised and purely aural statements made by various speakers were presented at distinct locations in the recipient's surroundings. It was concluded that place provides especially privileged cues and that not all content-correlated background stimuli are equipotent cues in associative learning. (Author/PN)

Examines (1) the effect of increased motor involvement with an environment on children's memory for spatial locations, and (2) the effect of different degrees of motor involvement under intentional and incidental memory conditions. Thirty boys and 30 girls at each of kindergarten and third-grade levels were individually tested in a large-scale,…

First and fifth graders estimated all interlocation distances among six objects in one of two environments: a familiar library or a novel arrangement of objects in a room. Findings suggest (1) an increase in the ability to shift among spatial frames of reference with development and (2) a sequence of mastery of spatial knowledge. (RH)

Presented are the results of three different studies with introductory psychology classes investigating the relationship between the subjects' perception of transversed distance and the angularity of the route traveled. (BT)

Spatial and sequential tasks performed both independently and jointly were compared for 40 undergraduates grouped by sex and dominant hand. When both tasks were performed simutaneously, there was a significant advantage for right-handers and a slight advantage for males. This was attributed to hemispheric interference left-handers experienced.…

Investigated the ability of kindergarten, first-grade and third-grade boys and girls to use a mnemonic strategy in a spatial task. (Author/DB)

Thirty-two preschool children were matched by age, sex, and pretest scores on spatial concept knowledge. Four groups were (1) instruction (see and hear) only, (2) verbal repetition, (3) fine motor treatment (hand manipulation), and (4) gross motor treatment (body movement). There was no difference in performance between groups given instruction…

Assessed age differences in spatial representation on a task involving sequentially encountered landmarks along an environmental route. Second graders, fifth graders, and college students were asked to make rank order distance comparisons of landmarks from viewing a sequence of slides of a walk through a commercial neighborhood. (Author/SS)

Examined whether spatial classification is discovered during play and if external products of play lead children to use space to represent similarity. Found through two experiments--a longitudinal study of four children's classification behaviors, and the examination of play behavior with two types of objects--that comparison of different kinds…

Presents a theoretical model of partial occlusion drawing, along with three experiments. Experiment one studied whether planning or scanning is involved in partial occlusion drawing, and the second explored whether group-encoding of similar objects creates a drawing problem. Experiment three tested predictions derived on the conjoint effects of…

Two experiments examined the effects of common motion, background texture, and orientation on four-month olds' perception of unity of a partially occluded rod. Results indicated that infants' perception of object unity is not dependent on a single visual cue but on a variety of cues including motion, interposition, depth cues, background texture,…

Scores on Raven's Progressive Matrices correlated positively with electroencephalogram-recorded alpha rhythm frequency (AF) in 101 healthy male adults, as did one test of verbal ability and one of mental performance. However, AF did not show significant relationships with general intelligence or spatial and arithmetic abilities. (SLD)

This article highlights ideas, adaptations, and strategies that have been effective for educators teaching students with visual impairments. Strategies are shared for teaching the concepts of left and right, using alphaboxes for teaching the alphabet, using CDs for Braille reinforcement activities, and using a lawn compass to teach orientation.…
