Bogomolova, Katerina; Vorstenbosch, Marc A. T. M.; El Messaoudi, Inssaf; Holla, Micha; Hovius, Steven E. R.; van der Hage, Jos A.; Hierck, Beerend P. – Anatomical Sciences Education, 2023
Binocular disparity provides one of the important depth cues within stereoscopic three-dimensional (3D) visualization technology. However, there is limited research on its effect on learning within a 3D augmented reality (AR) environment. This study evaluated the effect of binocular disparity on the acquisition of anatomical knowledge and…

Fazzi, Elisa; Signorini, Sabrina G.; La Piana, Roberta; Bertone, Chiara; Misefari, Walter; Galli, Jessica; Balottin, Umberto; Bianchi, Paolo Emilio – Developmental Medicine & Child Neurology, 2012
Aim: Cerebral visual impairment (CVI) is a disorder caused by damage to the retrogeniculate visual pathways. Cerebral palsy (CP) and CVI share a common origin: 60 to 70% of children with CP also have CVI. We set out to describe visual dysfunction in children with CP. A further aim was to establish whether different types of CP are associated with…

Thomas, Shery; Proudlock, Frank A.; Sarvananthan, Nagini; Roberts, Eryl O.; Awan, Musarat; McLean, Rebecca; Surendran, Mylvaganam; Kumar, A. S. Anil; Farooq, Shegufta J.; Degg, Chris; Gale, Richard P.; Reinecke, Robert D.; Woodruff, Geoffrey; Langmann, Andrea; Lindner, Susanne; Jain, Sunila; Tarpey, Patrick; Raymond, F. Lucy; Gottlob, Irene – Brain, 2008
Idiopathic infantile nystagmus (IIN) consists of involuntary oscillations of the eyes. The familial form is most commonly X-linked. We recently found mutations in a novel gene "FRMD7" (Xq26.2), which provided an opportunity to investigate a genetically defined and homogeneous group of patients with nystagmus. We compared clinical features and eye…

Children Perceive Large-Disparity Random-Dot Stereograms More Readily than Adults.
Peer reviewed Peer reviewed
Dowd, John M.; And Others – Journal of Experimental Child Psychology, 1980
Tests the hypothesis that children will be better than adults at perceiving depth at large disparities in random-dot stereograms. Subjects were 4, 6, 8, and 25 years of age, with six males and six females in each of the four age groups. (MP)

Perceived Movement in the Visual Crib.
Ball, William A.; Dibble, Ann – 1978
In this study, two similar depth perception experiments were conducted to investigate 3-month-old infants' perception of changes in depth while they were being moved. In the first, the subjects, 18 infants (80 to 105 days old) were lowered face down towards the textured floor of a 3-sided enclosure (visual crib). Three experimental conditions were…
