PURPOSE To validate the Impact of Vision Impairment for Children (the IVI_C), a new vision-specific pediatric instrument designed to assess the affect of impaired vision on quality of life (QoL) in children. METHODS The IVI_C was administered to vision-impaired and normally sighted students, 8 to 18 years of age. Reliability and validity were tested, and the IVI_C was subjected to Rasch analy...

A cross sectional, prevalence survey of eye disease in the population over 75 years old of Melton Mowbray has been used to examine the accuracy and completeness of the Blind and Partially Sighted Registers. The Blind Register had high sensitivity and specificity but was found to underestimate the prevalence of blindness by a factor of 1.1. The Partially Sighted Register had high specificity, bu...

Gaze signals, frequently used by the sighted in social interactions as visual cues, are hardly accessible for low-vision and blind people. In this paper, we proposed a prototype, namely Tactile Band, to aim at testing the hypothesis that tactile feedback can enable the blind person to feel attention (gaze signals) from the sighted, enhancing the level of engagement in face-to-face communication...

This qualitative study addresses the role of assistive technology in English language learning experiences blind and visually impaired students. Underpinned by interpretivist theory, in-depth, semi-structured interviews were conducted with ten students studying at IIU NUML universities Islamabad. All given a chance to give detailed account regarding their experiences. The revealed that BVI who ...

Fast food is popular among children and adolescents; however, its consumption has often been associated with negative impacts on nutrition and health. This study examined current fast food consumption status among middle school students and explored factors influencing fast food consumption by applying Theory of Planned Behavior. A total of 354 (52.5% boys) students were recruited from a middle...

The present research examined whether the recognizable nonverbal expressions associated with pride and shame may be biologically innate behavioral responses to success and failure. Specifically, we tested whether sighted, blind, and congenitally blind individuals across cultures spontaneously display pride and shame behaviors in response to the same success and failure situations--victory and d...

Blindness can be a driving force behind a variety of changes in sensory systems. When vision is missing, other modalities and higher cognitive functions can become hyper-developed through a mechanism called sensory compensation. Overall, previous studies suggest that olfactory memory in blind people can be better than that of the sighted individuals. Better performance of blind individuals in o...

Early blind persons have often been shown to be superior to sighted ones across a wide range of non-visual perceptual abilities, which in turn are often explained by the functionally relevant recruitment of occipital areas. While voice stimuli are known to involve voice-selective areas of the superior temporal sulcus (STS) in sighted persons, it remains unknown if the processing of vocal stimul...
