Investigates students' early concepts of area by analyzing responses to a worksheet of items that involved visualizing the tiling of given figures. Concludes that half of the students had difficulty visualizing the tiling of shapes, but those students who participated in spatial activities were generally more successful in determining the number…

Used Magnetic Resonance Imaging to examine the relation between cognitive skill and the cortical activation engendered by linguistic or visual-spatial strategies in a sentence-picture task. Results with 12 adults indicate that language and visual-spatial processing are supported by partially separable networks of cortical regions and suggests the…

Used functional magnetic resonance imaging (fMRI) to examine spatial working memory in 8- to 11-year-olds tested under 3 conditions. Found that subtracting activation of the motor condition from the memory condition revealed activity in dorsal aspects of the prefrontal cortex and in the posterior parietal and anterior cingulate cortex. Analysis of…

Two experiments investigated the role of spatial prototypes in estimates of location. Found that adults and children ages 7 to 11 years overestimated distances between target locations in different regions and that none displaced objects toward the region centers. Even with boundaries removed during testing, adults and children overestimated…

Adults aged 50-59 (n=12), 60-69 (n=28), and 70+ (n=24) completed Piaget's three mountains task, which tests ability to extrapolate another's viewpoint. Compared with younger subjects (n=13), their performance significantly decreased with age and egocentrism rose significantly. A possible explanation is perceived difficulty of the task rather than…

The retrieval of temporal-order versus spatial-location information was investigated using fMRI. The primary finding in the hippocampus proper, seen in region of interest analyses, was an increase in BOLD signal intensity for temporal retrieval, and a decrease in signal intensity for spatial retrieval, relative to baseline. The negative BOLD…

This study investigates whether the right hemisphere has more flexible contrast gain control settings for the identification of spatial frequency. Right-handed participants identified 1 and 9 cycles per degree sinusoidal gratings presented either to the left visual field-right hemisphere (LVF-RH) or the right visual field-left hemisphere (RVF-LH).…

Visual-spatial ability has been identified as one of the primary factors of intelligence. Numerous tests, including paper-and-pencil tasks and laboratory experiments, have attempted to provide an accurate measure of this ability. However, the majority of these tests serve only as surrogate measures of visual-spatial ability and may not provide a…

In this paper I illustrate how kinaesthetic experiences associated with dance might be used in teaching to promote engagement and learning in spatial, rhythmic, structural and symbolic aspects of mathematics.

Utilization of a footprint trail for locating a hidden person may indicate the extension of semiotics to the spatial domain of search. We sought to determine whether young children implemented footprint tracking, and found that at 3-years they successfully tracked footprints on only 3% of trials, at 4-years on 9% of trials, and at 5-years on 41%…

In two experiments in a Morris pool, rats were trained to find a hidden platform which was located in a specific position in relation to two objects, B and F, which were presented together, one in front of the other. One object, B, was just above the platform (a beacon for the platform, the critical object) while the second object, F, was above…

A central problem for psychology is vision's reaction to perspective. In the present studies, observers looked at perspective pictures projected by square tiles on a ground plane. They judged the tile dimensions while positioned at the correct distance, farther or nearer. In some pictures, many tiles appeared too short to be squares, many too…

This study investigated whether brain neural activity that accompanied the processing of previously learned map information was influenced by the modality in which the spatial parameters of the maps were originally learned. Participants learned a map by either viewing it directly or by reading an equivalent verbal description. Following learning,…

This study examined the role of stimulus characteristics in a visuospatial order reconstruction task in which participants were required to recall the order of sequences of spatial locations. The complexity of the to-be-remembered sequences, as measured by path crossing, path length, and angles, was found to affect serial memory, in terms of both…

Although considerable progress has been made in understanding how adults perceive their direction of self-motion, or heading, from optic flow, little is known about how these perceptual processes develop in infants. In 3 experiments, the authors explored how well 3- to 6-month-old infants could discriminate between optic flow patterns that…
