Albrecht, Matthew A.; Stuart, Geoffrey W.; Falkmer, Marita; Ordqvist, Anna; Leung, Denise; Foster, Jonathan K.; Falkmer, Torbjorn – Journal of Autism and Developmental Disorders, 2014
Recently, there has been heightened interest in suggestions of enhanced visual acuity in autism spectrum disorders (ASD) which was sparked by evidence that was later accepted to be methodologically flawed. However, a recent study that claimed children with ASD have enhanced visual acuity (Brosnan et al. in "J Autism Dev Disord"…

Wilhelmsen, Gunvor B – Improving Schools, 2016
Although good visual capacity is essential for children's learning, we have limited understanding of the various visual functions among school starters. In order to extend this knowledge, a small-scale study was undertaken involving 24 preschool children age 5-6 years who completed a test battery originally designed for visual impairment…

Fellinger, J.; Holzinger, D.; Dirmhirn, A.; van Dijk, J.; Goldberg, D. – Journal of Intellectual Disability Research, 2009
Background: Early identification of deaf-blindness is essential to ensure appropriate management. Previous studies indicate that deaf-blindness is often missed. We aim to discover the extent to which deaf-blindness in people with intellectual disability (ID) is undiagnosed. Method: A survey was made of the 253 residents of an institute offering…

Wong, Alex W. K.; Chan, Chetwyn C. H.; Li-Tsang, Cecilia W. P.; Lam, Chow S. – Research in Developmental Disabilities: A Multidisciplinary Journal, 2009
We investigated the task processes which hinder people with intellectual disabilities (ID) when using the human-computer interface. This involved testing performance on specific computer tasks and conducting detailed analyses of the task demands imposed on the participants. The interface used by Internet Explorer (IE) was standardized into 16…

Soderstrom, Carl A. – Gerontology & Geriatrics Education, 2008
The aging process is associated with medical conditions that can negatively affect medical fitness to drive. Traditional licensing agency methods to identify at-risk drivers have significant limitations. These include testing of visual acuity and driving tests. Recently, methods have been developed to allow for screening for cognitive decline in…

Orfield, Antonia – Principal Leadership, 2008
Vision is the dominant sense, and the eyes are connected with almost every other part of the brain. If the vision system is poorly developed, children trying to learn suffer. Without good up close vision, students are handicapped even if no one knows or suspects it--they may not even know it themselves. Students do not know that the way they see…

Leman, Rachel; Clausen, Michelle M.; Bates, Janice; Stark, Lee; Arnold, Koni K.; Arnold, Robert W. – Journal of School Nursing, 2006
Early detection of significant vision problems in children is a high priority for pediatricians and school nurses. Routine vision screening is a necessary part of that detection and has traditionally involved acuity charts. However, photoscreening in which "red eye" is elicited to show whether each eye is focusing may outperform routine acuity…
