Perception of Invariants by Five-Month-Old Infants: Differentiation of Two Types of Motion.
Peer reviewed Peer reviewed
Gibson, Eleanor J.; And Others – Developmental Psychology, 1978
Five-month-old infants were habituated to three types of visually presented rigid motion, with duration of fixation as the dependent measure. After reaching a criterion of habituation, a fourth rigid motion (not habituated) and a deformation were presented. (Author/SS)

The Ecological Optics of Infancy: The Differentiation of Invariants Given by Optical Motion.
Gibson, Eleanor J. – 1977
This paper deals with research on the development of infants' ability to perceive invariant features of things and the relation of objects to both the spatial layout of the infants' environment and to themselves. Basic assumptions regarding the perception of invariance are discussed and a theoretical view of the role of motion in the development…

The Development of Reaching and Looking Preferences in Infants to Objects of Different Sizes.
Peer reviewed Peer reviewed
Newman, Christopher; Atkinson, Janette; Braddick, Oliver – Developmental Psychology, 2001
Recorded reaching and looking preferences and movement kinematics among 5- to 15-month-olds divided into 3 age groups. Found that 5- to 12-month-olds preferred looking first at a large object; 8.5- to 12-month-olds showed preference for reaching to smaller (graspable) objects. Kinematic measures suggested that onset of object-oriented action…

Attention and Memory for Faces and Actions in Infancy: The Salience of Actions over Faces in Dynamic Events.
Peer reviewed Peer reviewed
Bahrick, Lorraine E.; Gogate, Lakshmi J.; Ruiz, Ivonne – Child Development, 2002
Three experiments investigated discrimination and memory of 5.5-month-olds for videotapes of women performing different activities (blowing bubbles, brushing hair, brushing teeth) or static displays after a 1-minute and a 7-week delay. Findings demonstrate the attentional salience of actions over faces in dynamic events to 5.5-month-olds. Findings…

Infants' Perception of Object Unity in Translating and Rotating Displays.
Peer reviewed Peer reviewed
Eizenman, Dara R.; Bertenthal, Bennett I. – Developmental Psychology, 1998
Three experiments examined 4- and 6-month-olds' sensitivity to the unity of a partly occluded moving rod undergoing translation, rotation, or oscillation. Findings suggested that all types of common motion were not equivalent for specifying infants' perceptions of occluded objects. (Author)

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…

Visual-Proprioceptive Intermodal Perception Using Point Light Displays.
Peer reviewed Peer reviewed
Schmuckler, Mark A.; Fairhall, Jennifer L. – Child Development, 2001
Three experiments explored 5- and 7-month-olds' intermodal coordination of proprioceptive information produced by leg movements and visual movement information specifying these same motions. Results suggested that coordination of visual and proprioceptive inputs is constrained by infants' information processing of the displays and have…
