Large-scale social surveys of visually impaired people often explore participants' mobility and travel behaviour. What is methodologically more challenging is gathering participant-centred data in relation to their own interpretation of the barriers they face. Findings from a national survey of visually impaired people are presented in this…

This article presents a model for understanding the development of visual perception from a dynamic systems theory perspective. It contrasts to a hierarchical or reductionist model that is often found in the occupational therapy literature. In this proposed model vision and ocular motor abilities are not foundational to perception, they are seen…

It is a widely accepted belief in clinical practice that children with a visual impairment can profit from the use of a low vision aid (LVA). However, we found a considerable gap in our scientific understanding of LVA use, particularly in young children. This is the reason for the analysis presented in this paper. A selected overview of LVA use in…

Children who are identified as visually impaired frequently have a functional vision assessment as one way to determine how their visual impairment affects their educational performance. The CVI Range is a functional vision assessment for children with cortical visual impairment. The purpose of the study presented here was to examine the…

This study used signal detection theory to conceptualize the problem a baseball batter faces when deciding whether or not to swing at a pitch. It examined the launch angle (LA) criteria used by expert (college players) and less experienced (recreational league players) batters using a baseball batting simulation. This study showed that, although…

This study examined the feasibility of the Atkinson Battery for Child Development for Examining Functional Vision (Atkinson, Anker, Rae, et al., 2002) to evaluate neurovisual functions of children with neurodevelopmental disorders in outpatient setting. A total of 90 patients underwent a comprehensive evaluation. Among these, a group of 33…

Purpose: The purpose of this paper is to offer a theoretical contribution to explicate the various factors and aspects that influence Senge's five disciplines and their outcomes. Design/methodology/approach: The paper develops a conceptual framework for the analysis of antecedents and outcomes of Senge's five disciplines, and offers moderators to…

Using a two-step approach, Van Soest et al. (2010) recently questioned the pertinence of the conclusions drawn by Bootsma and Van Wieringen (1990) with respect to the visual regulation of an exemplary rapid interceptive action: the attacking forehand drive in table tennis. In the first step, they experimentally compared the movement behaviors of…

In an influential study, R. J. Bootsma and P. C. W. van Wieringen (1990) argued that 2 of their 5 participants used visual information continuously during the attacking forehand drive in table tennis, its brief duration vis-a-vis the visuomotor delay notwithstanding. The authors repeated Bootsma and van Wieringen's experiment and included a…

Languages consistently distinguish the path and the manner of a moving event in different constituents, even if the specific constituents themselves vary across languages. Children also learn to categorize moving events according to their path and manner at different ages. Motivated by these linguistic and developmental observations, we employed…

This article reviews the structure, development, function, and assessment of the visual system and then considers: common eye problems of young children with visual impairment; impacts of severe impairment on child development; and the roles of early intervention professionals, ophthalmologists, and pediatricians in working with these children and…

This article describes the development and evaluation of a short form of the 24-item Adaptation to Age-Related Vision Loss (AVL) scale. The evaluation provided evidence of the reliability and validity of the short form (the AVL12), for significant interindividual differences at the baseline and for individual-level change in AVL scores over time.…

When assessing the visual function of young children, it is important to use a variety of tests. It is essential to have a structured observation method when it is not possible to use ordinary acuity tests. A structured observation method can be created by using a checklist. An ideal checklist should be handy and reliable and include a minimum of…

Intended for either the general educator or the specialist, this text offers principles and teaching strategies for teaching students with visual impairments including both blind students and those with low vision. The book is organized into three sections: "Vision,""Learning," and "Testing and Transitions." The four chapters in the "Vision"…

Background: Accountability demands are increasingly pushing school leaders to explore more data and do more sophisticated analyses. Data-driven decision making (DDDM) has become an emerging field of practice for school leadership and a central focus of education policy and practice. Purpose: This study examined principals' DDDM practices and…
