Visual system is crucial to autobiographical memory. Research tended to show that blind adults may compensate for the loss of visual information in retrieval of their autobiographical memories. Much less is known about how blind children's autobiographical memory develops in the absence of visual information. Using cue-word methodology, 36 sighted…

Introduction: This study aims to assess the prevalence of visual impairment and refractive error among learners who are deaf or hard of hearing in schools for Deaf students in Ghana. Methods: A descriptive cross-sectional study design was used to assess the distance visual acuity with the logMAR "E" chart, and ocular health was assessed…

This cross-sectional study aimed to investigate developmental changes in the efficiency of sustained, selective, and divided attention in a group of children aged 6-12 years by means of a computerized test battery. Participants included 199 children (51% female, majority White) who had normal or corrected-to-normal vision and no history of either…

This study investigates the individual difference antecedents of students' behavioural intention to use VR-based learning systems, especially from an integrated perspective of Big Five personality traits and perceived physiological vulnerability to IT use (PPVITU). Data collected from 149 respondents are tested against the research model using the…

Blind adults display language-specificity in their packaging and ordering of events in speech. These differences affect the representation of events in "co-speech gesture"--gesturing with speech--but not in "silent gesture"--gesturing without speech. Here we examine when in development blind children begin to show adult-like…

The eye should have a particular focal length in order to see an object. As there are many things to see, the focal length of the eye must vary because these things are not all at the same distance from the eye. We explore the eye accommodation from a geometrical optics point of view and present our results in this paper; the study includes a…

Introduction: Past studies have provided evidence that the effects of tactile stimulation on binocular rivalry are mediated by primitive features (orientation and spatial frequency) common in vision and touch. In this study, we examined whether such effects on binocular rivalry can be obtained through the roughness of naturalistic objects. In…

Background: Reading failure is far higher among disadvantaged students than among other students (National Center for Education Statistics, 2019). Many attempts to solve this have focused on schools, yet non-school factors have a substantial impact on learning (Clabaugh, 2008). One of these is uncorrected vision. Approximately 20-25% of school-age…

Background: In 2012, Chicago Public Schools and the Chicago Department of Public Health partnered together to create the Chicago School-Based Vision Program (CSBVP). This ongoing, city-wide program provides school-based vision services (eye examinations, eyeglasses provision, and eye care referrals) to students with limited access. Methods:…

This article investigates the optics conceptions of 228 Thai high school students in grades 10-12 when they attempted to explain how an object can be seen both in general and in a completely dark room. To elicit students' conceptions precisely, their confidence in giving reasons for the final two diagnostic questions is also considered. The study…

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 =…

Background: Documented inequalities in access to eye care for people with learning disabilities and/or autism are caused by poor uptake of primary eye care services, poor identification of eye problems, lack of signposting and reasonable adjustments of existing services, concerns about costs of care and the low priority historically given to these…

Past work has shown that eye movements are affected by long-term memory across different tasks and instructional manipulations. In the current study, we tested whether these memory-based eye movements persist when memory retrieval is under intentional control. Participants encoded multiple scenes with six objects (three faces; three tools). Next,…

This study aimed to develop a valid and reliable instrument that measures the functional vision of students with low vision. Thus, an assessment tool and performance activities were developed for three vision skill groups (near vision skills, distance vision skills, and visual field) that include functional vision skills. The universe was 1485…

Poor mental health--compared to that of the neurotypical child population--is a serious concern for many autistic children and young people around the world. In the UK, we have an increasing number of autistic young people receiving care in NHS funded in-patient mental health facilities. While sensory processing differences have now been added to…
