An experimental, intervention group of 4 children with moderate mental retardation received 10 therapy sessions focused on symbolic play development. Compared to a nonintervention group, the experimental children, aged 5-10, demonstrated increased amounts of symbolic play as well as higher levels of symbolism in their play behavior. (Author/JDD)

Discusses the findings of a recent study concerning the ability of an infant to see an object as a symbol. Reports that infants between 36 and 39 months old significantly outperformed informed infants between 30 and 32 months old on a symbolic task. (TW)

Reports on a study in which the symbolic relation between a scale model and the larger space that it represents was displayed by two groups of young children. Three-year-old children outperformed 2.5-year-olds in finding an object in a room after seeing an analogous object hidden in a model. (TW)

Discusses the importance of maps in geographical and environmental education. Reports on a study done with elementary school age children using aerial photographs. Indicates that children at age four can name some of the symbols on an aerial map, and by age six could recognize a majority of the symbols. (TW)

A structured system of visual features is seen to parallel the propositional hierarchy of operations usually associated with the parsing of algebraic expressions. Women more than men were found to depend on these visual cues. Possible causes and consequences are discussed. Subjects were secondary and college students. (Author/DC)

Twenty-eight hearing college students were trained on 30 signs from American Sign Language that had been classified as iconic, opaque, or abstract. Students learned and retained iconic signs better than opaque or abstract. A videotaped presentation mode produced greater consistency in scores than computer-assisted instruction. (Author/JDD)

Investigates two questions: (1) the sex-related differences in Landsat Mastery, road map reading, and map drawing among adolescents and (2) the relationship between spatial ability and mapping skills. Replicates significantly lower female performance on parts of the Landsat tasks. Concludes that spatial ability correlations with mapping are too…

Presents four educational experiments reflecting Jerome Bruner's theories on iconic and enactive representation to emphasize the need for more research on how children learn. Advocates greater institutional cooperation among schools, teachers, and researchers to improve research implementation and reduce problems of school disruption and…
