Deaf-sighted, deaf-blind, and hearing-sighted people have been interacting within a small community in the Bay Islands of Honduras for over a century (Ali 2023; Ali and Braithwaite 2020). In this article, we sketch the history of the community and the ways in which signers make use of their own and their interlocutor's bodies to co-construct…

Introduction: Many tactile graphics designed for individuals with visual impairments consider single factors. According to the results of our previous study, there may be interactions among scale, representation, and complexity factors. We conducted this integrative study with these three factors. Additionally, for the representation factor, we…

Although very rare, the existing research on the biological education of blind people indicates that teaching content is not fully in line with the sensory perception of that content by the blind. The aim of this study is to analyse the morphological details which the blind can register in multisensory plant research and to harmonise the…

Introduction: The authors of this study evaluated the necessary features of tactile maps to provide independent, efficient, and safe travel across a university campus; and a process for developing tactile maps based on user needs and preferences. Methods: Participants who have low vision provided input, through interviews and field tests,…

This study of 48 children with congenital blindness who attended mainstream schools focused on the tactile and haptic skills they needed in typical academic and everyday tasks. The results showed that, in general, the children mastered such tactile tasks, but some items posed special problems. (Contains 4 tables.)

This article analyzes the attraction of stimulation produced by a visuotactile sensory substitution device, which was designed to provide optical information to infants who are blind via a tactile modality. The device was first tested on sighted infants, to demonstrate that this type of stimulation on the abdomen is pleasant and rewarding in…

Viewers who study photographs of scenes tend to remember having seen beyond the boundaries of the view ["boundary extension"; J. Exp. Psychol. Learn. Mem. Cogn. 15 (1989) 179]. Is this a fundamental aspect of scene representation? Forty undergraduates explored bounded regions of six common (3D) scenes, visually or haptically (while blindfolded)…

Conducted two experiments to investigate phonological and tactual coding in Braille reading by blind children. Results revealed a phonological effect in blind children's reading of single words. Also direct lexical access, from tactual input, proceeded with the same facility for the blind as does visual input for the sighted. (Author)

Differences in how the two hemispheres of the brain handle spatial information were studied with blind subjects and blindfolded sighted subjects. The performances of all groups declined as the relative disorientation between the target and its duplicate increased, suggesting that visual imagery is not crucial to mental rotation. (Author/SEW)
