Forty five-year-olds compared two arms of an L-shaped figure on-axis or perpendicular to axis inside circles of different diameters. In making perceptual judgments about the relative length, the children tended to describe the on-axis line as longer. The context model of visual anomalies was supported. (Author/CM)

The effect of direction of motion on the difficulty of slides, flips, and turns for first, third, and fifth graders was examined. The study considered only students with no training in transformation tasks. The investigation found that the sex main effect was not significant. (Author/MP)

Language arts (oral and written communication), physical education (communication with motor skills), and mathematics (communication with words and symbols), are seen to present the most natural environment for instruction on spatial relations. Activities are suggested which can combine these areas and provide pupils with an enjoyable learning…

Infants 8.5 and 9.5 months of age were tested for ability to determine the location of an object hidden in one of two covered containers before their left-right positions were reversed. Only the older infants provided with different colored covers to their containers were able to do this task. (Author/DB)

A review of work related to the topological primacy thesis and a critique of some aspects of it are presented. On the basis of the psychological research, it is concluded that topological concepts ought to be taught. (MP)

Seven-year-olds compared successively presented oblique lines which varied as to their position within a square display and their relation to the diagonal axis of the display. Children apparently encoded lines in terms of position and axis features. They used a categorical spatial representational system to compare oblique lines. (Author/RD)

When the mathematics and extended range vocabulary subtests on the Relief Format Assessment Test were factor analyzed, altitude estimation (predicted by mathematics aptitude) and terrain analysis (predicted by vocabulary skills) were found to underly map-reading performance. Solutions were found to be dependent on verbal-analytic ability more than…

Offers strategies to encourage girls to see the value of studying science and mathematics and to continue studying these subjects. Strategies focus on career relevance, role models, creating confidence, and developing spatial skills in females. (Author/SK)

Reviews the formation of space, time, and measurement concepts in children with respect to Piagetian developmental levels and presents some teaching methods to help promote these concepts. (SK)

This experiment tested the ability of people to recall the locations of buildings in a familiar campus setting. Ten graduate students represented the relative locations of buildings by pairwise distance judgments and by direct mapping of locations on a Tektronix cathode ray terminal. Both methods led to accurate judgments. (Author/CTM)

This experiment investigated preferences for the location of facilities in an ideal town. Ten graduate students represented the relative locations of facilities (home, school, factory) by two methods: (1) pairwise ideal distances on a 100-point scale and (2) direct planning of locations on a Tektronix cathode ray screen. (Author/CTM)

Examined children's recall of the spatial configurations of an environment after the children followed prearranged paths and encountered barriers to movement. When asked to reconstruct the environmental configuration from memory, males estimated distances more accurately than did females. No age differences were noted. (Author/DB)

This inquiry had two aims: to assess children's ability to interpret maps in geography; to relate the assessed ability to maturity of thought as proposed by Peel, general intelligence, and age. It was found that performance on four tests depended more on intelligence than on maturity of thought or age. (Author/SJL)

Four articles consider brain hemisphere functioning of gifted students as it relates to gifted programs; alternation of education methodologies; spatial ability as an element of intellectual gifted functioning; and the interaction between hemisphere specialization, imagery, creative imagination, and sex differentiation.

The article describes a study undertaken to investigate the impact of geographical training (controlled experience) on junior high school students' ability to interpret topographical maps. Findings indicated that those students with more developed spatial skills (often resulting from a greater amount of geographical training) performed better on…
