Children ages 4, 8, 12, 16, and adults responded to 24 paintings concerning three subject matters and varying in realism and space depiction. Five-factor analysis of variance indicated that the triple interaction of subject matter, realism, and spatial depth was significant for all. Preferences are discussed by age group. (SJL)

Two experiments using varying duration exposures related reading skill in adults to initial encoding of location information. Results suggest that the role of perception in reading has been underestimated because emphasis has been on item perception, not perception of spatial location. (Author/CP)

A 3D mental rotation task was used to measure spatial performance in boys and girls in Ghana and Scotland. Sex differences of equal magnitude appeared in both cultures. In light of these findings, the author discusses genetic and environmental theories of spatial ability and the problems in testing such skills. (SJL)

The study evaluated the hypothesis that familial left-handed children, who presumably have bilateral representation of language ability, should show an impairment in spatial abiblity on 44 children (22 right handed, 11 familial left handed, and 11 nonfamilial left handed) whose average age was 8 years old.

Presents a ping-pong activity to teach the coordinate plane that puts students in a position to experience and relate to the coordinate plane in a manner that evokes their visual, spatial, and physical senses while linking the plane with a familiar object. (ASK)

Examined the effects of using Logo or problem-solving oriented simulation software on the spatial and critical thinking skills of fifth graders. Found that the Logo group had a significant pretest-posttest change in spatial scores, and the Simulation group had a significant pretest-posttest change in critical thinking scores. No significant change…

The effects of four different instructional formats (orthographic drawing, isometric drawing, physical model, and isometric and physical model together) on learning outcomes and strategies for spatial tasks were studied with 40 secondary students. Findings indicate that physical models cause the least extraneous cognitive load. (SLD)

An 18-item "Shortened Visuospatial Questionnaire" (SVS) was validated twice, first by verifying that children (ages 8-13) identified with the SVS questionnaire as having visuospatial learning disability (VSLD) (n=54) actually showed visuospatial deficits on psychometric evaluation, and second, by rating with the SVS a clinically identified…

It is generally accepted that males are superior to females in spatial ability. To test this assumption, the Silver Drawing Test (SDT) was administered to students 12 to 15 years old (33 girls and 33 boys) attending public schools in Nebraska, New York, and Pennsylvania. No significant differences in spatial ability were found. (KW)

Visual-spatial orienting in 10 high-functioning adults with autism was examined. Compared to controls, subjects responded faster to central than to lateral stimuli, and showed a left visual field advantage for stimulus detection only when laterally presented. Abnormalities in attention shifting and coordination of attentional and motor systems are…

The construct validity of the Category Test (W. C. Halstead, 1947) was studied for 308 adults with heterogeneous cognitive dysfunction. Factor analysis indicated that Category subtests load on three factors distinct from intelligence: (1) symbol recognition/counting; (2) spatial position reasoning; (3) and proportional reasoning. Clinical…

Describes an activity inspired by the work of Nobel Prize winner Dorothy Crowfoot Hodgkin involving multilink blocks that helps students develop three-dimensional spatial skills. (YDS)

Presents the results from two meta-analyses of the Mozart Effect studies. Explains that in Christopher Chabris' meta-analyses, 16 studies with subjects (n=714) and 12 studies with subjects (n=522) were analyzed; while in the author's meta-analysis 36 studies with subjects (n=2,465) and 31 studies with subjects (n=2,089) were analyzed. (CMK)

Summarizes findings from research related to spatial abilities. Provided are suggestions for developing spatial abilities. Lists nine references. (YP)

Two authors introduce the topic of visualization in mathematics education. Fourteen articles are briefly described. (YP)
