Stuart, Geoffrey W.; Lambeth, Sandra E.; Day, Ross H.; Gould, Ian C.; Castles, Anne E. – Brain and Cognition, 2012
Visual attention has temporal limitations. In the attentional blink (AB) a stream of stimuli such as letters or digits are presented to a participant on a computer monitor at a rapid rate. Embedded in the stream are two targets that the participant must try to identify. Identification of the second target is severely impaired if it is presented…

Havik, Else M.; Kooijman, Aart C.; Steyvers, Frank J. J. M. – Journal of Visual Impairment & Blindness, 2011
The effectiveness of different types of verbal information provided by electronic travel aids was studied in a real-life setting. Assessments included wayfinding performance and the preferences of 24 visually impaired users. The participants preferred a combination of route information and environmental information, even though this information…

Vincent, Claude; Lachance, Jean-Paul; Deaudelin, Isabelle – Assistive Technology, 2012
This study sought to compare road safety of new drivers with low vision who have followed a specific pilot bioptic training program with other groups of drivers all matched for age and driving experience. A quasi-experimental design was used two years after drivers obtained their license. Drivers were classified in the experimental group (n = 10,…

Sodnik, Jaka; Jakus, Grega; Tomazic, Saso – Journal of Visual Impairment & Blindness, 2012
Introduction: This article reports on a study that explored the benefits and drawbacks of using spatially positioned synthesized speech in auditory interfaces for computer users who are visually impaired (that is, are blind or have low vision). The study was a practical application of such systems--an enhanced word processing application compared…

Damen, S.; Kef, S.; Worm, M.; Janssen, M. J.; Schuengel, C. – Journal of Intellectual Disability Research, 2011
Background: Individuals in group homes may experience poor quality of social interaction with their professional caregivers, limiting their quality of life. The video-based Contact programme may help caregivers to improve their interaction with clients. Method: Seventy-two caregivers of 12 individuals with visual and intellectual disabilities…

Hallemans, Ann; Ortibus, Els; Truijen, Steven; Meire, Francoise – Research in Developmental Disabilities: A Multidisciplinary Journal, 2011
Locomotion of children and adults with a visual impairment (ages 1-44, n = 28) was compared to that of age-related individuals with normal vision (n = 60). Participants walked barefoot at preferred speed while their gait was recorded by a Vicon[R] system. Walking speed, heading angle, step frequency, stride length, step width, stance phase…

Stoffregen, Thomas A.; Ito, Kiyohide; Hove, Philip; Yank, Jane Redfield; Bardy, Benoit G. – Journal of Visual Impairment & Blindness, 2010
Adults who are blind stood in a room that could be moved around them. A sound source moved with the room, simulating the acoustic consequences of body sway. Body sway was greater when the room moved than when it was stationary, suggesting that sound may have been used to control stance. (Contains 1 figure.)

Guerette, Amy R.; Smedema, Susan Miller – Journal of Visual Impairment & Blindness, 2011
The relationship between perceived social support and multiple indicators of well-being in adults with visual impairments was investigated. The results included significant correlation of social support and depressive symptoms, satisfaction with life, as well as with physical, psychological, economic, family, and social well-being. Implications…

van de Wouw, E.; Evenhuis, H. M.; Echteld, M. A. – Research in Developmental Disabilities: A Multidisciplinary Journal, 2012
In people with intellectual disability (ID), impaired sleep is common. Life expectancy has increased in this group, and it is known that in general population sleep deteriorates with aging. Therefore the aims of this systematic review were to examine how sleep problems are defined in research among adults and older people with ID, and to collect…

Smith, Kimberly R. M.; Matson, Johnny L. – Research in Developmental Disabilities: A Multidisciplinary Journal, 2010
Assessing social skills is one of the most complex and challenging areas to study because behavioral repertoires vary depending on an individual's culture and context. However, researchers have conclusively demonstrated that individuals with intellectual disabilities (ID) have impaired social skills as well as those with co-morbid autism spectrum…

Papadopoulos, Konstantinos S.; Arvaniti, Evmorfia K.; Dimitriadi, Despina I.; Gkoutsioudi, Vasiliki G.; Zantali, Christina I. – British Journal of Visual Impairment, 2009
Visual processes undoubtedly play an important role in print reading as well as in spelling. In the present study we intend to compare the spelling performance of visually impaired individuals (both individuals who are blind and individuals with low vision) with that of their fully sighted peers. An analysis of errors (misspelled words and…
