Investigates whether spatial situation models are constructed in naturalistic story comprehension. Claims that, during normal reading, readers are not very much engaged in constructing, maintaining, and updating a spatial situation model. (HB)

Tested infants' remembrance of the orientations and angular relations of line segments. In one experiment, infants "dishabituated" to a change in orientation but not a change in angle. In two further experiments, infants familiar with either an acute or obtuse angle gave strong novelty preferences to a different angle. (BC)

When spatial ability was regressed on a measure of general intelligence in a large national sample of 12th graders, a bimodal distribution of spatial ability was found among low scoring students, suggesting two qualitatively different types of individuals. Characteristics of these students are discussed, and an organic impairment is suggested as…

A study, including research and practice notes by various authors, investigated whether extended training in an acoustically rich environment could enhance the spatial updating ability of 12 adults with congenital blindness. After training, the adults' distance perception from a home-base location and novel locations was superior to a sighted…

Examined the role that gender differences play in the determination of the components influencing the difficulty of spatial ability items. Results for 2,245 examinees taking a spatial ability test that is part of the Dental School Admission Battery show that component difficulties show little variation across gender. (SLD)

This study investigated whether deafness contributes to enhancement of visual spatial cognition, independent of knowledge of sign language. Comparison of 12 congenitally deaf children not exposed to sign language and 12 matched hearing controls found that the groups did not differ in their performance on visual spatial skills tests. (Author/DB)

Comparison for memory for spatial location of 30 persons with and 30 persons without mental retardation found the control group recalled more intentionally learned than incidentally learned locations. The experimental group performed better after incidental learning than after intentional learning and scored as highly as controls on incidental…

Retinitis pigmentosa (RP) causes restriction of the visual field, progressive vision loss, and night blindness. This article presents an overview of the most common problems in orientation and mobility (O&M) for individuals with RP, appropriate interventions, vision science discoveries related to RP, and the impact of RP on functional visual…

Answers several questions regarding background information on research in spatial skills. Describes strategies that graphics educators can adopt to develop these skills in students. (Author/CCM)

Participants acquired spatial knowledge of a fictitious island by studying either (a) a complete physical map, (b) a sequence of part maps each showing the outline of the island and a subset of the landmarks, or (c) a sequence of sentences each describing a part map. During test, they verified the direction between 2 landmarks. Spatial knowledge…

Two experiments explored how infants learn to form an abstract categorical representation of support (i.e., on) when habituated to few (i.e., 2) or many (i.e., 6) examples of the relation. When habituated to 2 pairs of objects in a support relation, 14-month-olds, but not 10-month-olds, formed the abstract spatial category (i.e., generalized the…

This research had three main goals: to control whether children would show significant improvement in cognitive test scores following piano/keyboard instruction; to compare whether the spatial tasks would show greater improvement than other tasks; and to examine whether the effects of piano/keyboard training on spatial tasks are gender…

Three studies compared 98 children with spina bifida myelomeningocele (SBM)--a disorder associated with high rates of math disability and spatial deficits--to 94 typically developing children on multidigit subtraction and cognitive addition tasks. Children with SBM were classified into those with reading decoding and math disability, only math…

Methods to automatically convert graphics into tactile representations have been recently investigated, creating either raised-line or relief images. In particular, we briefly review one raised-line method where important features are emphasized. This paper focuses primarily on the effects of such emphasis and on comparing both raised-line and…

Sex differences on language and visuospatial tasks are of great interest, with differences in hemispheric laterality hypothesized to exist between males and females. Some functional imaging studies examining sex differences have shown that males are more left lateralized on language tasks and females are more right lateralized on visuospatial…
