We investigate how vision affects haptic performance when task-relevant visual cues are reduced or excluded. The task was to remember the spatial location of six landmarks that were explored by touch in a tactile map. Here, we use specially designed spectacles that simulate residual peripheral vision, tunnel vision, diffuse light perception, and…

Going to the movies or watching Saturday morning cartoons has become a fixture of contemporary American life, but have you ever stopped to contemplate how those "moving" images on film are conveyed to our eyes and brain? The movement that we see on film is actually a series of still images, every image separated from the next by brief spaces of…

Past research (e.g., J. M. Loomis, Y. Lippa, R. L. Klatzky, & R. G. Golledge, 2002) has indicated that spatial representations derived from spatial language can function equivalently to those derived from perception. The authors tested functional equivalence for reporting spatial relations that were not explicitly stated during learning.…

The scientific model of how people see things is far removed from children's real-world experience. They know that light is needed in order to see an object, but may not know that light is reflected off the object and some of that light enters the eyes. In this article, the author explores children's understanding of reflection and how to develop…

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.…

The resource guide identifies products which assist visually impaired individuals in accessing IBM (International Business Machine) Personal Computers or the IBM Personal System/2 family of products. An introduction provides a general overview of ways computers can help persons with visual handicaps. The document then provides descriptions of…

Vision is a critical piece of the educational reform puzzle that anchors and gives meaning to the whole. America's current vision for education promotes universal education access, factory-model organization approach, learning as a passive activity, raw ability as a performance determinant, and a basic skills emphasis for average students. Except…

This document contains teacher's materials for an instructional module on how to conduct a visual screening that was developed through use of the Dick and Carey model of instructional design. More than a third of the document consists of a description of the model's use and adaptation in the development of the module. Section headings are as…

Aimed at tutors with some experience of adult literacy work, this handbook offers information and advice that should help them adapt their teaching approaches to meet the needs of partially sighted students. It outlines the situations that are likely to arise during the tutoring situation with an explanation of common sense procedures and simple…

Intended for teachers of deaf-blind and severely handicapped students as well as for resource or itinerant teachers in the area of vision who have recently begun to serve low functioning students, the manual provides information on vision and on vision assessment. The manual serves three functions. It: (1) prepares teachers for participation in…

Some research indicates that a number of children understand vision as an outreaching of the sense, and that they are the originator of the process (Eaton, Anderson, & Smith, 1983; Guesne, 1985). The children draw arrows or rays that point out of the eyes, sometimes returning to the head, and write that vision involves the eyes seeing or…
