Tests infants' dual-process performance (a process mediating response decrements called habituation and a state-dependent process mediating response increments called sensitization) on visual habituation-dishabituation tasks. (HOD)

Examines 3-month-old infants' perception of "camouflaged" forms that were only visible when moving. Shows infants effectively use kinetic information to organize visual input in higher-order structures. (HOD)

Second and third graders and fifth and sixth graders were tested in a very large, unfamiliar environment to determine the relation of their knowledge of an abstract reference frame to performance on a spatial inference task. (HOD)

Three experiments with observers aged 6 to 21 years of age examined the integration of shape information over successive glances. Results indicated age-related improvements in the sequential integration of shape information, both when integration occurs through successive glimpses over space and when information is separated only in time. (HOD)

Examines children's understanding of what variables and relations are important in problem structures, and their use of these variables and relations in problem solving. (HOD)

Research is reported which investigated the ability of four-month-old hearing infants to discriminate between gestures derived from American Sign Language. Findings show that infants possess the perceptual abilities to differentiate between signs that differ solely in terms of contrasts along a single underlying movement direction. (SED)

Five-, five-and-a-half-, and seven-month-old infants were tested for sensitivity to relative size as distance information. Infants viewed two equidistant, different-sized objects presented side by side and reaching was used as dependent measure. Findings revealing five-and-a-half- and seven- but not five-month-olds were sensitive to relative size…

Compares the response of preterm and full-term infants to moving objects presented with or without accompanying sound. Finds differences in attention and recognition between full-terms and preterms at three months of age. At six months of age only high-risk preterms showed different responses than full-terms, suggesting that they are at a…

The article reviews the role of the vestibular system, tactile system, kinesthetic system, visual system, balance, locomotion, body awareness, spatial system, mildline crossing, bilateral integration, form perception, and eye-food coordination in promoting an integrated motor base on which later learning is built. (CL)

To reverse the general decline in school performance, educationists must restructure learning experiences to balance the present fragmented and specialized linear processes with the sensory/spatial processes, so that an educational system commensurate with the neutral balance of both cerebral hemispheres might emerge. (MB)

Critiqued are five reviews of research puporting to examine the effectiveness of perceptual training in the improvement of reading. (DB)

Dot patterns varying in type of symmetry (double, vertical and horizontal symmetry, and asymmetry) were presented tachistoscopically for 200 msec, followed by a patterned mask, to 16 subjects in each grade level: kindergarten, second, and fourth-grade. (Author/JH)

Examines the effectiveness of Frostig-Horne and Kephart-Getman techniques and materials in developing the perceptual and motor skills of young children. (TO)

The brain perceives, but its perceptions are conditioned by environment. Traditionally education has reinforced that conditioning; today it must give insight into its arbitrainess and cultural ideosyncrasy. (Author/JH)
