Corn, Anne L.; Lusk, Kelly E. – Journal of Visual Impairment & Blindness, 2018
Introduction: The purpose of this study was to gain information from parents in the United States about their children with albinism. The article focuses on information and services related to medical care and low vision care. Methods: An online questionnaire was used to collect data, and parents had opportunities to submit additional information.…

Sauer, Theodor; Lawrence, Linda; Mayo-Ortega, Liliana; Oyama-Ganiko, Rosa; Schroeder, Stephen – Journal of Mental Health Research in Intellectual Disabilities, 2018
The prevalence of refractive error and ocular disorders among infants and young children with severe behavioral problems and developmental disorders is not well defined, particularly in developing countries. We performed a retrospective review of ophthalmic examinations performed during a National Institutes of Health--funded cohort study of very…

Thompson, Stacy D.; Merino, Sarah – Young Exceptional Children, 2018
Visual Impairments (VIs) are ranked as the fourth most common disability in the United States and are viewed as the most common restricting condition during childhood. It has been reported that 17% to 25% of school-aged children have some degree of a vision problem, thus interrupting their potential to reach optimal growth and learning in school.…

Hedlich, Christina; Barstow, Elizabeth; Vogtle, Laura K. – Journal of Visual Impairment & Blindness, 2018
The National Eye Institute (2015) reports that by the year 2050, the number of individuals with age-related macular degeneration (AMD) will rise from 2.07 million to 5.44 million. AMD causes central vision loss, which can affect independence in activities such as medication management, meal preparation, and personal finances (Smallfield, Clem…

Warrington, Kayleigh L.; McGowan, Victoria A.; Paterson, Kevin B.; White, Sarah J. – Journal of Experimental Psychology: Learning, Memory, and Cognition, 2018
Reductions in stimulus quality may disrupt the reading performance of older adults more when compared with young adults because of sensory declines that begin early in middle age. However, few studies have investigated adult age differences in the effects of stimulus quality on reading, and none have examined how this affects lexical processing…

Austerweil, Joseph L.; Griffiths, Thomas L.; Palmer, Stephen E. – Cognitive Science, 2017
How does the visual system recognize images of a novel object after a single observation despite possible variations in the viewpoint of that object relative to the observer? One possibility is comparing the image with a prototype for invariance over a relevant transformation set (e.g., translations and dilations). However, invariance over…

Su, Yanfang; Willis, Gordon; Salomon, Joshua A. – Field Methods, 2017
Vignette design has been largely neglected in anchoring vignette studies. This study aimed to contribute to the science of vignette design by developing and evaluating vignettes for measuring vision in rural China. Cognitive interviews were conducted among 36 participants in a Chinese middle school. The respondents either directly evaluated vision…

Ivarsson, Jonas – Frontline Learning Research, 2017
This study looks at the practice of thoracic radiology and follows a group of radiologists and radiophysicists in their efforts to find, discuss, and formulate issues or troubles ensuing the implementation of a new radiographic imaging technology. Based in the theoretical tradition of ethnomethodology it examines the local endogenous practices…

Gegenfurtner, Andreas; Kok, Ellen M.; van Geel, Koos; de Bruin, Anique B. H.; Sorger, Bettina – Frontline Learning Research, 2017
Functional neuroimaging is a useful approach to study the neural correlates of visual perceptual expertise. The purpose of this paper is to review the functional-neuroimaging methods that have been implemented in previous research in this context. First, we will discuss research questions typically addressed in visual expertise research. Second,…

Leat, Susan J.; Si, Francis Fengqin; Gold, Deborah; Pickering, Dawn; Gordon, Keith; Hodge, William – Journal of Visual Impairment & Blindness, 2017
Introduction: In addition to optical devices, closed-circuit televisions (CCTVs) and eccentric viewing training are both recognized interventions to improve reading performance in individuals with vision loss secondary to age-related macular degeneration. Both are relatively expensive, however, either in the cost of the device or in the amount of…

Wiese, Holger; Komes, Jessica; Tüttenberg, Simone; Leidinger, Jana; Schweinberger, Stefan R. – Journal of Experimental Psychology: Learning, Memory, and Cognition, 2017
Difficulties in person recognition are among the common complaints associated with cognitive ageing. The present series of experiments therefore investigated face and person recognition in young and older adults. The authors examined how within-domain and cross-domain repetition as well as semantic priming affect familiar face recognition and…

Gover, Glen Bruce – ProQuest LLC, 2017
This qualitative phenomenological case study is designed to investigate the learning outcomes, lived experiences, and perceptions of eight post-secondary teachers participating in a sketch-based infographic development training program. This research is designed to assess the viability of infographics as a learning and assessment strategy,…

Kotsopoulos, Donna; Zambrzycka, Joanna; Makosz, Samantha – Mathematical Thinking and Learning: An International Journal, 2017
The purpose of the present study was to determine whether there are visual-spatial gender differences in two-year-olds, to investigate the environmental and cognitive factors that contribute to two-year-olds' visual-spatial skills, and to explore whether these factors differ for boys and girls. Children (N = 63; M[subscript age] = 28.17 months)…

Smith, Danielle; Ropar, Danielle; Allen, Harriet A. – Journal of Autism and Developmental Disorders, 2017
In autism spectrum disorder (ASD), atypical integration of visual depth cues may be due to flattened perceptual priors or selective fusion. The current study attempts to disentangle these explanations by psychophysically assessing within-modality integration of ordinal (occlusion) and metric (disparity) depth cues while accounting for sensitivity…

Murry, Matthew W. E.; Isaacowitz, Derek M. – International Journal of Behavioral Development, 2017
Older adults tend to have lower emotion-perception accuracy compared to younger adults. Previous studies have centered on individual characteristics, including cognitive decline and positive attentional preferences, as possible mechanisms underlying these age differences in emotion perception; however, thus far, no perceiver-focused factor has…
