This article describes and analyzes the development of a navigation and orientation system for people with visual impairments as it evolved over three decades. It includes reflections on how users have been involved in the redesign process and illustrates how people with and without disabilities have collaborated to create a more suitable and…

Age-related macular degeneration (AMD) is the leading cause of legal blindness among persons aged 50 years and older and is most prevalent among individuals of European descent aged 65 and older (Friedman et al., 2004; Rosenthal & Thompson, 2003). By affecting central vision, AMD interferes with such tasks as reading, driving, and activities…

This article examines the Alphabetic Braille Contracted Braille Study in relation to the dimensions of collaborative research: extent, intensity, substance, heterogeneity, velocity, formality, and productivity. It also discusses the dimensions of financing research and researchers' attitudes. The overall consensus is that the study would not have…

Background: The purpose of this study was to determine the feasibility and reliability of the modified Berg Balance Scale (mBBS) in persons with severe intellectual and visual disabilities (severe multiple disabilities, SMD) assigned Gross Motor Function Classification System (GMFCS) grades I and II. Method: Thirty-nine participants with SMD and…

Introduction: This exploratory study determined whether transcribing selected test items on an adult life and work skills reading test into braille could maintain the same approximate scale-score range and maintain fitness within the item response theory model as used by the Comprehensive Adult Student Assessment Systems (CASAS) for developing…

Persons with special needs have innate abilities and when properly harnessed through proper education would be able to contribute ultimately to their development as well as that of the society they reside in terms of political, social, economic and technological development. Before such group of persons can be properly educated there is the dire…

This paper reports a study that focused on three risk factors that may be relevant for forming relationships with peers, namely, level of vision loss, low extroversion (high introversion), and parental overprotection. The authors analyzed the role of parental overprotection and extroversion in forming relationships with peers among 158 adolescents…

The article is an invited presentation given by Dr. Cary A. Supalo to the National Federation of the Blind of Illinois annual state convention that was held in Chicago, Illinois on Saturday, October 28, 2011. The remarks were slightly modified for the "Journal of Science Education for Students with Disabilities."

Accurately aligning to a crosswalk is an important component of safe street crossing for pedestrians who are blind. Six alignment cues were evaluated in a simulated crosswalk environment in which the angle of the crosswalk was not always in line with the slope of the ramp. The effectiveness of each cue is reported and implications are discussed.…

Five cues were evaluated with respect to their usefulness in directing the headings of pedestrians who were blind during street crossings. The study was conducted at a simulated crosswalk, with the angle of the crosswalk varied relative to the approach and direction of the slope of the ramp. Three cues worked well over the distance equivalent to…

Introduction: The study compared the level of satisfaction of 101 graduates with a distance education versus an on-campus program. Methods: A self-administered anonymous survey was used to gather information about satisfaction from the recent graduates of a university personnel preparation program in visual impairments (response rate = 57.7%). The…

A range of neurobehavioral impairments, including impaired visual perception and visual-motor integration, are found in very preterm born children, but reported findings show great variability. We aimed to aggregate the existing literature using meta-analysis, in order to provide robust estimates of the effect of very preterm birth on visual…

This Practice Report describes the development and implementation of the "Maine Employability Skills Program," a model employment program developed by the Maine Division for the Blind and Visually Impaired (DBVI). The program was designed to support the efforts of the chronically unemployed or underemployed. These consumers were either…

The aim of this systematic review of the literature is to increase understanding of the factors that influence the labor force participation of persons who are visually impaired. Labor force participation was associated with many factors, such as communication training and education. Future research should focus on high-quality studies of labor…

The development of attention is critical for the young child's competence in dealing with the demands of everyday life. Here we review evidence from infants and preschool children regarding the development of three neural subsystems of attention: selective attention, sustained attention, and attentional (executive) control. These systems overlap…
