The visual system is tuned by its inputs. The behavior of reading offers a unique way to examine tuning for visual representations (letters) because readers have massive experience recognizing letters in a systematic context (reading). One aspect of reading is that letters are highly crowded within words, which severely limits their…

What is vision's role in driving early word production? To answer this, we assessed parent-report vocabulary questionnaires administered to congenitally blind children (N = 40, Mean age = 24 months [R: 7-57 months]) and compared the size and contents of their productive vocabulary to those of a large normative sample of sighted children (N =…

Purpose: This study aims to examine whether binocular vision plays a facilitating or impeding role in lexical processing during sentence reading in Chinese. Method: Adopting the revised boundary paradigm, we orthogonally manipulated the parafoveal and foveal viewing conditions (monocular vs. binocular) of target words (high- vs. low-frequency)…

The focus of this quantitative study was on analyzing the self-concept of the students with visual impairment in Lahore (Pakistan). A modified self-description questionnaire used by Jayne E. Stake (1992) was used to assess the six subscales (Likability, Task accomplishment, Morality, Power, Giftedness and Vulnerability) of the self-concept of the…

With the technological improvements of innovative portable recording gadgets, augmented researchers' interest in exploring students' visual attention in their natural and normal occurring classrooms. The purpose of this study was to gauge students' visual attention in their Mathematics and English classrooms. This article reports on a study…

Because children with visual impairments tend to be inactive, they are 1.5 times more likely to be considered overweight or obese than are their sighted peers. Although some barriers to physical activity have been identified (for example, lack of opportunity and transportation issues); little has been done to empirically identify predictors of…

One core question in studies of language processing is the extent to which interlocutors engage in real-time communicative perspective-taking. Current evidence suggests that both children and young adult listeners are able to draw on common ground (shared knowledge) to guide referential interpretation. However, less is known about older listeners,…

Purpose: Studies have suggested that the use of visual information may underlie the benefit associated with an external focus of attention. Recent studies exploring this connection have primarily relied on motor tasks that involve manipulation of an object (object projection). The present study examined whether vision influences the effect of…

More than 20 percent of all school-aged children in the United States have vision problems, and low-income and minority children are disproportionately likely to have unmet vision care needs. Vision screening is common in U.S. schools, but it remains an open question whether screening alone is sufficient to improve student outcomes. We implemented…

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…

This study evaluates the effectiveness of an intervention programme administered to blind and sighted school students. The students were given information concerning style, author and technique of three paintings from three different artistic periods, as well as guidelines to assess the overall aesthetics of each image. This programme was…

In the present study, the aim was to examine the differences in performance between children and adolescents with visual impairment and sighted peers in the water-level task. Twenty-eight individuals with visual impairments, 14 individuals with blindness and 14 individuals with low vision, and 28 sighted individuals participated in the present…

Introduction: To compare the health status of older adults with and without vision impairment, this study employed a disability framework consisting of four stages, progressing from risk factors; through pathology and impairments that result in declining functioning; and eventually to disability. Methods: Data from five rounds (1999 to 2008) of…

In the typical human visual system, the macula allows for high visual resolution. Damage to this area from diseases, such as age-related macular degeneration (AMD), causes the loss of central vision in the form of a central scotoma. Since no treatment is available to reverse AMD, providing low vision rehabilitation to compensate for the loss of…

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…
