This study compared improvements in visual function of 20 Spanish children with low vision, ages 4 to 6 years. Children received either the Barraga and Morris program or the Frostig program, or placebo control or no treatment. No significant differences between treatment groups were found. (DB)

Examined persistence of sensory memory by studying developmental differences in recall of attended and ignored lists of digits for second-graders, fifth-graders, and adults. Found developmental increase in the persistence of memory only for the final item in an ignored list, which is the item for which sensory memory is thought to be the most…

Examines the relationship between perceptual modality measured by the Swassing-Barbe Modality Index (SBMI) to musical aptitude measured by Primary Measures of Music Audiation (PMMA) in kindergarten students. Reports correlations between the measures that support findings at other grade levels. Supports the theory that perceptual modalities become…

Introduces the concepts of online and offline sampling and highlights the role of online sampling in agent-based models of learning and development. Compares the strengths of each approach for modeling particular developmental phenomena and research questions. Describes a recent agent-based model of infant causal perception. Discusses limitations…

Maintains that advances in the literature on perception-action development suggests that tool use may be a more continuous developmental achievement than previously believed. Suggests new research directions, including efforts to investigate the processes by which children detect and relate affordances between objects, coordinate spatial frames of…

When presented with several time-compressed sentences, young adults' performance improves with practice. Such adaptation has not been studied in older adults. To study age-related changes in perceptual learning, the authors tested young and older adults' ability to adapt to degraded speech. First, the authors showed that older adults, when equated…

Recent studies have reported that preverbal infants are able to discriminate between numerosities of sets presented within a particular modality. There is still debate, however, over whether they are able to perform intermodal numerosity matching, i.e. to relate numerosities of sets presented with different sensory modalities. The present study…

PURPOSE: This research determined the psychometric quality of a criterion-referenced measure that was thought to measure preschoolers' print-concept knowledge (PCK). METHOD: This measure, titled the Preschool Word and Print Awareness (PWPA), was examined using the partial credit model (PCM) to determine its suitability for use by clinicians,…

This research paper reports on testing the hypothesis that music and spatial task performance are causally related. Two complementary studies are presented that replicate and explore previous findings. One study of college students showed that listening to a Mozart sonata induces subsequent short-term spatial reasoning facilitation and tested the…

Recently, some researchers are considering the effects of classroom environment on student achievement and attitudes. Due to the concerted effort of a number of educators, remarkable progress has been made over the last quarter of a century in conceptualizing, assessing and researching this area of concern. However, today there is growing concern…

Research findings are reviewed concerning infants' abilities to discriminate parents from other social stimuli during the first 6 months of life. The term "discrimination" is used to signify the ability of infants to respond differentially to two or more social stimuli. Studies reviewed are categorized in terms of the visual, auditory,…

A series of studies with adults resulted in a standardized test to assess children's comprehension of main ideas in simple narratives. The test, utilizing stories from the WISC-R picture arrangement task, was then employed in a developmental investigation with second, fifth, and eighth grade students. Each student completed the WISC-R arrangement…

The purpose of this study was to investigate the hypothesis that instruction in pictorial depth perception will enable children to perceive depth more often in pictures, to offer a larger number of appropriate explanations for their dimensional judgments, and to attain their best performances when realistc materials are employed.

Although there are many remediation materials for learning disabled children available commercially, with more being produced none are as universally available or as economical as comic strips. (Author)
