Two experiments involving 42 students from the Model Secondary School for the Deaf investigated both the visual and tactile components in the processing of spatial information. Test measures used were the Figures Rotations Test, Group Embedded Figures Test, and Tactile Rotations Test. The study suggested that spatial reasoning is a determining…

Explores longstanding inconsistencies in Piaget's account of development of spatial representation and perspective-taking. Examines Piaget's early writings and the findings of the original "three mountains" experiment. Concludes that Piaget's alternative theory is compatible with contemporary thinking and is important as a contributory…

Examines the ability of six- and eight-year-old children to hide and recover 20 marbles in a large room containing 100 possible sites. Shows that children tend to concentrate activities in sections of the room and are sensitive to clusters of proximal sites. (HOD)

Investigates effects of perceptual salience and specific orientation values on 16 kindergarten and fourth-grade children executing a speeded sorting task. Kindergarten results supported the cognitive processing prediction that orientation sorting times would vary as a function of condition, but no differences were obtained for the fourth-grade…

In this developmental study of sustained cognitive monitoring, second graders, sixth graders, and college students followed a two-part sequence of spatial directions and then made judgments about reaching the destination intended by direction giver. Cognitive monitoring skills of the type examined appear to be useful in many real-world cognitive…

With first-grade and college students, examines barrier effects as a function of the task used to assess subjects' cognitive maps. One group, asked to give rank-ordering judgments, had to keep an entire spatial layout in mind. The second group made direct estimates of the distance between two objects. (RH)

Research in progress on some unresolved issues regarding the relationship of cognitive development and language acquisition is reported, especially the relationship between conservation of length and knowledge of relevant comparative dimensional adjectives. Much further investigation is recommended and possible educational implications are…

Two studies of development of spatial representation with two dimensions found that children as young as five years use the same two independent dimensions in fine-grained spatial coding of location in a circle as adults use--radius and angle. The adult pattern, where angle as well as radius is coded hierarchically, emerges by nine years. (HTH)

Measured cognitive processing time, imagery skill, and spatial memory span of 128 children and adults, ages 8 to 20 years. Found that performance on spatial memory span tasks was largely predicted by imagery skill, which in turn was strongly linked to processing time; age was much less of a predictor in both cases. (EAJ)

Reviews the development of spatial organization in children with blindness. Discusses the importance of motor exploration, tactual development, and spatial representation as critical factors in developing spatial and cognitive organizations of their surroundings. Suggests seven specific activities to improve spatial organization in blind children.…

Examined geographical representations among children and young adults. Found that a distinct home region was apparent at age 9. At age 11, children divided North America into regions the same as university students. Children used new location information to update location estimates. Children preserved ordinal structure of initial location…

Ten language impaired and 10 language normal children, aged 3-5), were asked to solve verbal and nonverbal problems requiring color and size judgments. There were no group differences on the verbal tasks, but the language impaired children performed less well on the nonverbal tasks especially on problems dealing with size. (Author/DB)

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)

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)

Proposes that humans may have evolved a special sensitivity to certain types of social information during rough-and-tumble play that facilitates social cognition. Describes the cognitive benefits of physical play as providing a break from demanding intellectual tasks and hypothesizes that physical play is related to gender differences in spatial…
