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…

Palmer, Stephen E.; Brooks, Joseph L. – Journal of Experimental Psychology: Human Perception and Performance, 2008
Edge-region grouping (ERG) is proposed as a unifying and previously unrecognized class of relational information that influences figure-ground organization and perceived depth across an edge. ERG occurs when the edge between two regions is differentially grouped with one region based on classic principles of similarity grouping. The ERG hypothesis…

Phenotypical Characteristics of Idiopathic Infantile Nystagmus with and without Mutations in "FRMD7"
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…

Arendasy, Martin E.; Sommer, Markus; Gittler, Georg – Intelligence, 2010
Marked gender differences in three-dimensional mental rotation have been broadly reported in the literature in the last few decades. Various theoretical models and accounts were used to explain the observed differences. Within the framework of linking item design features of mental rotation tasks to cognitive component processes associated with…

Anderson, Barton L. – Psychological Review, 2007
There has been a growing interest in understanding the computations involved in the processes underlying visual segmentation and interpolation in conditions of occlusion. P. J. Kellman, P. Garrigan, T. F. Shipley, and B. P. Keane and M. K. Albert defended the view that identical contour interpolation mechanisms underlie modal and amodal…

Choi, Gil Ok – ProQuest LLC, 2008
For the past few years, virtual environments (VEs) have gained broad attention from both scholarly and practitioner communities. However, in spite of intense and widespread efforts, most VE-related research has focused on the technical aspects of applications, and the necessary theoretical framework to assess the quality of interfaces and designs…

Kuchemann, Dietmar – Mathematics Teaching Incorporating Micromath, 2007
Perspective is a rich area for mathematical work, and one that should be accessible to many students, since it is based on the everyday experience of viewing the 3D world directly and through familiar 2D representations (drawings, photographs, images on a television or cinema screen, etc). A nice feature of perspective tasks is that they can be…

Wang, Yushun; Zhuang, Yueting – International Journal of Distance Education Technologies, 2008
Online interaction with 3D facial animation is an alternative way of face-to-face communication for distance education. 3D facial modeling is essential for virtual educational environments establishment. This article presents a novel 3D facial modeling solution that facilitates quasi-facial communication for online learning. Our algorithm builds…

Peer reviewedGranrud, Carl E.; And Others – Child Development, 1984
A total of 20 infants either five or seven months of age viewed computer-generated random-lot displays in which accretion and deletion of texture provided the only information for contours. Infants of both age groups showed significant preferences to reach for the apparently nearer regions in the displays. (Author/RH)

Peer reviewedTeske, John A.; And Others – Journal of Experimental Child Psychology, 1992
Children drew pictures of two objects placed in side-by-side or end-to-end views. Objects faced forward, backward, right, or left in such a way that one object occluded the other in some views. Children produced fewer drawings depicting occlusions for end-to-end than for side-by-side alignments. (BC)
