Efficiency in Visual Scanning by Children with and without Visual Disabilities.
Peer reviewed Peer reviewed
Knowlton, Marie – Exceptional Children, 1997
Visual scanning behavior and efficiency of 22 children with visual disabilities and 25 children without disabilities (ages 3.5 to 10 years) were studied. Significant differences were found between groups in length of scan path and number of objects reported, but no significant differences in scanning efficiency. Coordinated binocular eye movements…

When May a Child Who Is Visually Impaired Recognize a Face?
Peer reviewed Peer reviewed
Markham, R.; Wyver, S. – Journal of Visual Impairment & Blindness, 1996
The ability of 16 school-age children with visual impairments and their sighted peers to recognize faces was compared. Although no intergroup differences were found in ability to identify entire faces, the visually impaired children were at a disadvantage when part of the face, especially the eyes, was not visible. Degree of visual acuity also…

Children's Construction of Horizontals, Verticals, and Diagonals: An Operational Explanation of the "Oblique Effect."
Peer reviewed Peer reviewed
Frye, Douglas; And Others – Developmental Psychology, 1986
Investigates the problem young children have in constructing diagonals, noting that, on the whole, they can not make diagonals in the horizontal/vertical configuration. (HOD)

The Degree of Hearing Loss and Lipreading Ability: An Example for the Doctrine of Sensory Compensation?
Beattie, R. G.; Markides, A. – ACEHI Journal, 1992
This study found significantly better lipreading scores by 31 children with hearing impairments than by 15 children with normal hearing (all 10 and 11 years old). However, correlations between degree of hearing loss and lipreading ability were nonsignificant. The study provides partial support for the doctrine of sensory compensation. (DB)

Control of Children's Observing Responses by Information Feedback during Visual Discrimination Learning.
Peer reviewed Peer reviewed
Whiteley, John H. – Journal of Experimental Child Psychology, 1985
Subjects from kindergarten-age to adult participated in four experiments. In order to view the stimuli, subjects in three experiments activated lights in viewing boxes; in the fourth experiment, stimulus fixations were measured using a corneal reflection technique. Results supported the view that visual observing is controlled by cognitive…

On Resource Strategy Limitations in Hyperactivity: Cognitive Impulsivity Reconsidered.
Peer reviewed Peer reviewed
Sergeant, Joseph A.; Scholten, C. A. – Journal of Child Psychology and Psychiatry, 1985
Reports the results of a high-speed search task administered to overactive and distractible (hyperactives), normoactive and distractible, and normoactive and attentive (controls) children. Instructions emphasized speed, accuracy, or both speed and accuracy. Indicates that controls and distractibles conformed to the fast guess model, which relates…

On Data Limitations in Hyperactivity.
Peer reviewed Peer reviewed
Sergeant, Joseph A.; Scholten, C. A. – Journal of Child Psychology and Psychiatry, 1985
Three groups of elementary school children, rated on activity and distractibility, were given a visual search task with three levels of display load and tested twice in two conditions of stimulus visibility. Encoding deficit or data limitation did not account for the attentional performance of either hyperactive or somewhat hyperactive subjects.…
