Twenty-four gifted children with learning disabilities and a control group of nondisabled gifted children were administered the Wechsler Intelligence Scale for Children-Revised. The 8- to 12-year-old subjects were found to be more reliant on verbal conceptualization and reasoning than controls and demonstrated deficiencies in short-term auditory…

Relevant orientation and mobility (OM) skills for visually impaired infants foster sensory, motor, and conceptual development. OM personnel need to consider alternative teaching models, personnel preparation needs, sensory aids issues, and research issues. (DB)

Two experiments investigated perceptual primacy of dimensional and similarity relations in stimulus classification of mentally retarded children. Results support a distinction between separable and integral stimulus structures, but do not support an integral-to-separable shift in perceptual development. Results suggest implications for…

This paper reviews, first, experimental studies of perceptual-cognitive development and related work directed to the assessment of infant intelligence and, second, naturalistic observation of the exploratory patterns of infants during free play. Techniques used, such as the Fagan Test of Infant Intelligence, offer the potential to identify…

Explored whether there are changes with age in understanding the specific distinction between natural and human-made phenomena and whether an appreciation of this distinction influences children's beliefs about the possibility of altering or transforming different categories of objects. Found that this distinction, a powerful organizer for adults,…

In this study of sensitivity to viewpoint, children between the ages of 6 and 14 years were asked to draw an L-shaped array of 3 cubes from 1 of 3 views. At every age, children showed sensitivity to their view in the sense that there were consistent differences between the drawings produced in the three viewing conditions. (SH)

Eighteen science activities that help children learn to use their senses are described. Multisensory activities and single-sensory activities are provided. Each activity includes a list of materials, the procedure, information for the teacher, questions, and a vocabulary list of words often used by children to describe what is taking place. (KR)

This study analyzed the efficacy of sensory integration treatment by combining data from a study of 96 Canadian children (29 from Alberta and 67 from Ontario children and all aged 5-8). Results indicate that the therapeutic effect of sensory integration treatment is not greater than other, more traditional methods of intervention. (Author/JDD)

Eye movements of 12-week-old infants were recorded in a visual encoding experiment. Results showed that infants who encoded more slowly scanned less extensively over the stimulus and engaged in prolonged fixation. An experiment with two-week olds showed significant age differences in the manner of visual scanning. (BC)

Children and adults performed a divided attention task and two selective attention tasks with shapes that were either spatially integrated or separated. Results indicate that integrated stimuli are initially perceived as wholes, and separated stimuli as features, at all ages. (BC)

Two experiments used Visual Expectations Procedure to investigate development of expectations in infants up to 12 months old. Reaction time improved and the percentage of anticipations increased between 6 and 9 months using an alternation pattern or a complex pivot pattern, and between 4 and 8 months when using a left-right alternation or a…

Sensory and motor experiences are essential in childhood and are the foundation for all higher level learning and skill acquisition. This paper examines how young children make sense of sensory experiences, focusing on infants and toddlers, preschoolers, and school-age children. It also looks at the importance of creating an environment rich in…

This study has important implications for microworlds such as Logo, HyperGami, and Newton's World, which use interaction to learn spatial mental models for science, math, geometry, etc. This study tested the hypothesis that interactively rotating (dragging) virtual shapes primes mental rotation. The independent variable was observation vs.…

Large gains in performance, evolving hours after practice has terminated, were reported in a number of visual and some motor learning tasks, as well as recently in an auditory nonverbal discrimination task. It was proposed that these gains reflect a latent phase of experience-triggered memory consolidation in human skill learning. It is not clear,…

This study examines the historical understanding of 22 fourth-graders and 11 fifth-grade students in two classrooms in a suburban community near Cincinnati (Ohio). The classes were homogeneous racially, with no students of Hispanic, African-American, Asian, or Pacific Island descent in either class. The school reflects primarily middle and…
