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…

In an authentic flight simulator, the instructor is traditionally located behind the learner and is thus unable to observe the pilot's visual attention (i.e. gaze behaviour). The focus of this article is visual attention in relation to pilots' professional learning in an Airbus A320 Full Flight Simulator. For this purpose, we measured and analysed…

Introduction: This study analyzed 39 data collection tools used by teachers of students with visual impairments when completing functional vision assessments (FVAs). Methods: In 2017, teachers of students with visual impairments submitted data collection tools used in the FVA process. These tools were then compared with the 23 FVA components…

Objective: This study aims at investigating the relationship between agility performance and perception and decision-making mechanisms of female basketball players. Materials and Methods: A total of seventeen elite female basketball player playing in Second League in Turkey Basketball Federation participated in this study voluntarily. The mean age…

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…

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…

Despite the discovery of body-selective neural areas in occipitotemporal cortex, little is known about how bodies are visually coded. We used perceptual adaptation to determine how body identity is coded. Brief exposure to a body (e.g., anti-Rose) biased perception toward an identity with opposite properties (Rose). Moreover, the size of this…

Report of a second target (T2) is impaired when presented within 500 ms of the first (T1). This attentional blink (AB) is known to cause a delay in T2 processing during which T2 must be stored in a labile memory buffer. We explored the buffer's characteristics using different types of masks after T2. These characteristics were inferred by…

This study investigated the online reading performances and the level of visual fatigue from the perspectives of non-native speaking students (NNSs). Reading on a computer screen is more visually more demanding than reading printed text. Online reading requires frequent saccadic eye movements and imposes continuous focusing and alignment demand.…

Brazilian Soccer began developing its current emphasis on peripheral vision in the late 1950s, by initiative of coach of the Canto do Rio Football Club, in Niteroi, Rio de Janeiro, a pioneer in the development of peripheral vision training in soccer players. Peripheral vision training gained world relevance when a young talent from Canto do Rio,…

This article reports on the ability of observers who are sighted and those with low vision to make time-to-collision (TTC) estimations using video. The TTC estimations made by the observers with low vision were comparable to those made by the sighted observers, and both groups made underestimation errors that were similar to those that were…

This study compared improvements in visual function of 20 Spanish children with low vision, ages 4 to 6 years. Children received either the Barraga and Morris program or the Frostig program, or placebo control or no treatment. No significant differences between treatment groups were found. (DB)

This study examined infants' change in visual information pick-up, from an infant-like stimulus-locked visual scanning pattern to an adult-like cognitive control of visual information pick-up. Subjects were 21 children between 25 and 42 months of age. Eye movements were videotaped in a preferential looking situation and later analyzed as still…

A study investigated whether the reading difficulties of 60 Dutch children with low vision were a matter of reduced visual input or a consequence of a lack of orthographic knowledge. Results indicated that reduced visual input was the only cause of the children's lower reading performance. (Contains references.) (Author/CR)

Compared was the performance of 30 nonhandicapped controls and 30 partially sighted British children (6-to 10-years-old) without other handicaps on tests of shape and letter recognition, visual perception and visuomotor skill, and spelling or reading accuracy or comprehension. (LH)
