The development of the Visual-Perceptual Chemistry Specific (VPCS) assessment tool is based on items that align to eight visual-perceptual skills considered as needed by chemistry students. This tool includes a comprehensive range of visual operations and presents items within a chemistry context without requiring content knowledge to solve…

Changes to a scene often go unnoticed if the objects of the change are unattended, making change detection an index of where attention is focused during scene perception. We measured change detection in school-age children and young adults by repeatedly alternating two versions of an image. To provide an age-fair assessment we used a bimanual…

The author discusses the role of perceptual training in the education of young perceptually handicapped children. Distinctions are drawn between perception and awareness, and the necessity of stimulation to encourage infant and child learning is emphasized. Commonalities between perception and learning are underscored. The author stresses that…

Research is reviewed on auditory-visual speech perception of hearing-impaired individuals. The review focuses on: the effects of competing noise, filtering, age, stimulus and noise, and hearing loss on perceptual behavior; bisensory communication evaluation procedures; and remediation of bisensory perceptual problems through consonant recognition…

Most language development hazards in infancy and early childhood fall into the categories of auditory impairment, central integrative dysfunction, inadequate environmental support, and peripheral expressive impairment. Existing knowledge and techniques are inadequate to meet the screening and assessment problems of central integrative dysfunction,…
