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…

O'Reilly, Michelle; Vollmer, Brigitte; Vargha-Khadem, Faraneh; Neville, Brian; Connelly, Alan; Wyatt, John; Timms, Chris; De Haan, Michelle – Developmental Science, 2010
Many studies report chronic deficits in visual processing in children born preterm. We investigated whether functional abnormalities in visual processing exist in children born preterm but without major neuromotor impairment (i.e. cerebral palsy). Twelve such children (less than 33 weeks gestation or birthweight less than 1000 g) without major…

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…

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)

Isaacs, Larry D. – 1980
Dynamic visual acuity (DVA) is defined as the performer's ability to visually discriminate parts of an object when there is relative motion between the target and the performer. According to research findings, this visual attribute may play a key role in motor-task performance. Researchers have found a significant relationship between DVA and…

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…

MANGRUM, CHARLES T. – 1967
SIGNIFICANT RESEARCH ON THE PHYSIOLOGICAL AND FUNCTIONAL ASPECTS OF VISION AND READING DISABILITY IS SURVEYED. CONCLUSIONS BASED ON THE LITERATURE IN THE FIELD ARE DISCUSSED. A BIBLIOGRAPHY OF 70 REFERENCES AND A GLOSSARY OF TERMS ARE APPENDED. A TABLE SUMMARIZING REFRACTIVE ERRORS AND EYE DEFECTS CONTRIBUTING TO READING DISABILITY IS INCLUDED.…

Mangrum, Charles T. – 1970
The degree of correlation existing between visual screening results obtained from the Keystone Visual Survey Telebinocular and the Titmus Biopter Vision Test was discussed. A sample of 59 children admitted to the University of Miami Reading Clinic during the 1969 summer session was used. They ranged in age from 7 to 16. All subjects were…

Livingstone, Margaret; Hubel, David – Science, 1988
Summarizes the anatomical, physiological, and psychological evidence related to the primate visual system. States that comparison of perceptual abilities with the electrophysiological properties of neurons may help deduce functions of visual areas. (RT)
