Toy playing habits, spatial abilities, and science and mathematics achievement of children aged 3 through 13 appear to be sex typed. Males play with a wider variety of toys, exhibit superior spatial skills, and maintain greater science and mathematics achievement scores than females. (PS)

Investigation of the language-spatial lateralization of 76 intermediate grade right-handed regular education students found that "good" students had normal left hemisphere language and right hemisphere spatial lateralization but "poor" students had nonnormal lateralization. Academic problems and behavior problems were correlated with nonnormal…

Examines the fallacies about the nature of abilities and learning and about the interaction between sense modalities which follow from the dichotomy in relation to explanations of spatial development in the blind. Suggests that interactions between cognitive and perceptual factors need to be considered to explain more adequately effects of sensory…

Students are asked to find different tiles that could be manufactured and show how a particular tile can be used to cover a floor. Thus, tessellations are explored. (MNS)

The effect of the location, in picture or text, of spatial, contextual, and operational information on comprehension was evaluated. Results showed that textual presentation of spatial information produced fewer errors, pictorial presentation reduced performance times, and pictorial presentation of contextual information reduced assembly times and…

A battery of spatial, linguistic, and mathematical tests was administered to tenth- and twelfth-grade students to examine the relation between sex differences on particular spatial tests and sex differences on particular mathematical problems. The sex difference magnitude was not diminished by taking spatial and linguistic scores into account.…

Undergraduates were given complex figural analogies items, and eye movements were observed under three types of feedback: (1) elaborate feedback; (2) subjects verbalized their thinking and application of rules; and (3) no feedback. Both feedback conditions enhanced the rule-governed information processing during inductive reasoning. (Author/GDC)

Investigated was how girls and boys who were discrepant in their spatial and verbal performance used spatial visualization skills in solving word problems and fraction problems. It was concluded that low spatial visualization skill may be more debilitating to girls' mathematical problem solving than to boys'. (MNS)

Experiments to probe the nature of one mode of thinking, imagined spatial operations, have been devised. Results confirm that the mind can model physical processes, subjecting them to the geometric constraints that hold in the external world. The experimental work and implications are discussed in detail. (MNS)

Reports on a study that investigated the perception in deaf children, aged 6 to 10, of American Sign Language signs that differ in only one major parameter to determine whether any of the three parameters (handshape, movement, and location) is more difficult than others for deaf children to discriminate. (SED)

Two experiments used fifth grade students to test the hypothesis that conjointly presented verbal/spatial information facilitates retrieval from either stimulus format. Results support the notion of conjoint retention which assumes that related verbal/spatial arrays are stored in a fashion which allows separate use of both formats during…

Nine experiments were performed to verify and extend studies on sex differences in problem solving conducted in the 1950s by Sweeney, Carey, Milton, Nakamura, and Berry. A 20-item problem set was administered to over 1,000 college students. Results indicated a male advantage, averaging 35 percent, virtually identical with 1950s results. (Author/BS)

Reanalysis of data for 13,200 twelfth-grade students indicated that sex has a significant effect on mathematics achievement even after controlling for sex differences in spatial abilities and background and interest in mathematics. Women tend to have less spatial visualization ability, and its effects on mathematics achievement are greater for…

Investigated relationships between visual-spatial abilities and achievement and what influence these abilities have on the high attribution rate characteristic of many introductory college-level science courses. Results, among others, using physics students (N=136) and nonscience majors (N=52), indicate that visual-spatial abilities influence…

Results of four related studies revealed (1) a trend toward better differentiation of the color attribute from four years through college-age; and (2) a possible stage of development, occurring before children can organize stimulus values conceptually or multidimensionally, in which they are able to organize or "dimensionalize" stimulus values…
