Infants' Sensitivity to the Depth Cue of Height-in-the-Picture-Plane
Peer reviewed Peer reviewed
Direct linkDirect link
Arterberry, Martha E. – Infancy, 2008
Five- and 7-month-old infants' sensitivity to the pictorial depth cue of height-in-the-picture-plane was assessed. Infants were presented with 2 objects, 1 higher than the other, and their reaching was recorded under monocular and binocular viewing conditions. The results showed that both age groups reached significantly more to the lower,…

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…

Infants' Sensitivity to Accretion and Deletion of Texture as Information for Depth at an Edge.
Peer reviewed Peer reviewed
Granrud, 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)

Infants' Sensitivity to Boundary Flow Information for Depth at an Edge.
Peer reviewed Peer reviewed
Craton, Lincoln G.; Yonas, Albert – Child Development, 1988
A sample of 44 infants of five months of age showed a significant reaching preference for the apparently nearer region of a computer-generated display. This indicated that the infants were sensitive to boundary flow information for depth at an edge. (RH)

Integration of Sequential Information for Shape Perception by Infants: A Developmental Study.
Peer reviewed Peer reviewed
Skouteris, H.; And Others – Child Development, 1992
Results of 3 experiments indicated that 12 month olds, but not 8 and 10 month olds, looked longer at objects of a different shape from test objects than at the test objects. Twelve month olds recognized rectilinear, but not curvilinear, forms. They recognized differences in forms for three-dimensional, but not two-dimensional, objects. (BC)

Sensitivity to Binocular Depth Information in Infants
Peer reviewed Peer reviewed
Gordon, F. Robert; Yonas, Albert – Journal of Experimental Child Psychology, 1976
In order to study infants' sensitivity to binocular information for depth, 11 infants, 20 to 26 weeks of age, were presented with real and stereoscopically projected virtual objects at three distances, and the infants' reaching behavior was videotaped. (Author/SB)

Infants' Responses to Optical Expansion: Avoidance Not Tracking.
Ball, William A. – 1977
In this study examining infants' responses to optical expansion, 18 infants between 36 and 61 days old watched expanding shadows that differed in the terminal location of the center of expansion and the number of dimensions undergoing change. Babies consistently rotated their heads upward during expansion of a closed figure when the center of…

Development of Sensitivity to Binocular Information for the Approach of an Object.
Peer reviewed Peer reviewed
Yonas, Albert; And Others – Developmental Psychology, 1978
Investigates the responsiveness of 14- and 20-week-old infants to binocular information using a stereoscopic shadow caster showing an object approaching on a collision course. (Author/SS)

Self-Produced Locomotion and the Development of Responsiveness to Linear Perspective and Texture Gradients.
Peer reviewed Peer reviewed
Arterberry, Martha; And Others – Developmental Psychology, 1989
Results indicate that seven-month-old infants are sensitive to the depth cues of linear perspective and texture gradients. Self-produced locomotor experience is not necessary for the development of sensitivity to static-monocular depth information. (RJC)

Infant Processing of Depth Information in Expanding Dot Patterns.

Ball, William A. – 1975
A looming paradigm was used to determine what depth information infants process in addition to that provided by the expansion of a single, closed contour of an object. A total of 18 male and 15 female infants aged 22-48 days watched a film in which the circular elements and inter-element spaces of the projected image alternately expanded and…

Four-Month-Old Infants' Sensitivity to Binocular and Kinetic Information for Three-Dimensional-Object Shape.
Peer reviewed Peer reviewed
Yonas, Albert; And Others – Child Development, 1987
A test for sensitivity to binocular disparity and a shape perception test were administered to four-month-olds. Results indicated that disparity-sensitive infants could perceive three-dimensional-object shape from kinetic and binocular depth information. (PCB)

Perceived Movement in the Visual Crib.
Peer reviewed Peer reviewed
Ball, William; Dibble, Ann – Journal of Genetic Psychology, 1980
Results of two studies were consistent with the view that 3-month-old infants perceive movement in depth during their own movement. They can move to avoid a surface just prior to contacting it. (Author/RH)

The Influence of Context on Amodal Completion in 5- and 7-Month-Old Infants
Peer reviewed Peer reviewed
Direct linkDirect link
Kavsek, Michael – Journal of Cognition and Development, 2004
Several investigations have shown that young infants perceive the unity of a center-occluded object when the visible ends of the object undergo common motion but not when the object remains stationary. This study is an extension of earlier investigations on object unity in that it assesses amodal completion of stationary circles in which one half…

A Comparison of Monocular and Binocular Depth Perception in 5- and 7-Month-Old Infants.
Peer reviewed Peer reviewed
Granrud, Carl E.; And Others – Journal of Experimental Child Psychology, 1984
Compares monocular depth perception with binocular depth perception in five- to seven-month-old infants. Reaching preferences (dependent measure) observed in the monocular condition indicated sensitivity to monocular depth information. Binocular viewing resulted in a far more consistent tendency to reach for the nearer object. (Author)

Perception of Object Unity in Young Infants: The Roles of Motion, Depth, and Orientation.
Peer reviewed Peer reviewed
Johnson, Scott P.; Aslin, Richard N. – Cognitive Development, 1996
Two experiments examined the effects of common motion, background texture, and orientation on four-month olds' perception of unity of a partially occluded rod. Results indicated that infants' perception of object unity is not dependent on a single visual cue but on a variety of cues including motion, interposition, depth cues, background texture,…
