This study investigated the tendency of deaf children (ages 6-13) not to spontaneously use active memory strategies such as rehearsal. Comparison of 38 deaf and 39 hearing students found that deaf students compensated for less effective rehearsal strategies by capitalizing on unique spatial features of the task. (Author/DB)

A total of 259 children between 5 and 12 years of age plotted the location and heading of an adult who was standing in their classroom onto a map of the classroom. Older children performed better than younger ones; boys performed better than girls. (MDM)

After a brief review of the contributions of factor analysis and regional analysis to the elaboration of the structures of spatial abilities, a facet design and regional model for spatial abilities are presented. A cylindrical-wedge model is proposed to represent the correlational structure of spatial ability tests. (SLD)

Studies how Singaporean children differentiate in drawing between a sphere and an elongated, straight-sided ovoid. Tests Piaget's and Inhelder's beliefs that very young children are unable to differentiate in their drawings between differently contoured shapes. Finds that children are able to show the difference in drawings between the two shapes.…

Opens with the theoretical construct of figural concepts. Argues that geometrical figures are characterized by both conceptual and sensorial properties. Investigates the effects of interaction between conceptual and figural components. Contains 19 references. (DDR)

Discusses the importance of using children's previous experiences with geometric figures to build foundations for developing geometric thinking. Describes how children's play with unit blocks can be structured to give them experiences with geometric concepts. Contains 12 references. (ASK)

Calculus students have great trouble visualizing solids of revolution and their cross sections. Illustrates the use of props in order to help students understand the solid revolution. (ASK)

Discusses the need for three-dimensional ideas in geometry. Describes a three-year sequence of projects that help develop students' spatial skills. (ASK)

Two studies with college students investigated the generalizability of the previously found suppression effect of mathematical achievement (as shown by high school grades in mathematics) on gender differences in spatial ability. The suppression effect was found to generalize to mathematically talented students and to a computerized task. (DB)

Three experiments examined the ability of 4- and 5-year- olds and adults to identify correspondences in spatial ratios. Results suggested that young children made accurate spatial proportionality judgments based on relational information and not on the exact form of the stimuli. Findings pose implications for theories of mathematical development…

Suggests that scientific thought experiments (TEs) draw upon three epistemological resources: conceptual-logical inferences, visual imagery, and bodily-motor experience. Argues that TEs are powerful because of students' thought capabilities related to imagination and visual imagery. Claims that TEs are not currently exploited by school learning…

Three studies, involving 72 3-month-old infants, demonstrated that infants remembered some of the original feature combinations of a mobile they had been trained to activate for up to 3 days but forgot all of them after 4 days. Even after 4 days, however, infants remembered the individual features that had entered into the original combinations.…

Examined effects of spatial precues on rapid execution of aim in 7-, 9-, and 11-year-olds, providing kinematic support to the role of precues in aiming tasks performed under temporal constraints. Found that precuing spatial dimensions of movement shortened reaction times as a function of the number of precued parameters. Spatial precues modified…

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…

Presents the observations of a panel of research experts who have conducted research on music and the brain. States that the participants are Andrea Halpern, Larry Parsons, Ralph Spintge, and Sandra Trehub. After an introduction of each person, the participants characterized their principal findings. (CMK)
