Infants' Perception of Chasing
Peer reviewed Peer reviewed

Frankenhuis, Willem E.; House, Bailey; Barrett, H. Clark; Johnson, Scott P. – Cognition, 2013
Two significant questions in cognitive and developmental science are first, whether objects and events are selected for attention based on their features (featural processing) or the configuration of their features (configural processing), and second, how these modes of processing develop. These questions have been addressed in part with…

Development of Perceptual Completion Originates in Information Acquisition
Peer reviewed Peer reviewed
Direct linkDirect link
Johnson, Scott P.; Davidow, Juliet; Hall-Haro, Cynthia; Frank, Michael C. – Developmental Psychology, 2008
Adults have little difficulty perceiving objects as complete despite occlusion, but newborn infants perceive moving partly occluded objects solely in terms of visible surfaces. The developmental mechanisms leading to perceptual completion have never been adequately explained. Here, the authors examine the potential contributions of oculomotor…

Synchronous Change and Perception of Object Unity: Evidence from Adults and Infants.
Peer reviewed Peer reviewed
Jusczyk, Peter W.; Johnson, Scott P.; Kennedy, Lori J.; Spelke, Elizabeth S. – Cognition, 1999
This study compared role of motion in adults' and infants' perception of object unity. Findings favored ecologically-oriented accounts of object perception. Motion was a determinant of object unity for infants. Alignment and common motion contributed to adults' object-unity perception; synchronous color changes did not. Infants detected…

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,…

Motion and Edge Sensitivity in Perception of Object Unity
Peer reviewed Peer reviewed
Direct linkDirect link
Smith, W. Carter; Johnson, Scott P.; Spelke, Elizabeth S. – Cognitive Psychology, 2003
Although much evidence indicates that young infants perceive unitary objects by analyzing patterns of motion, infants' abilities to perceive object unity by analyzing Gestalt properties and by integrating distinct views of an object over time are in dispute. To address these controversies, four experiments investigated adults' and infants'…

Where Infants Look Determines How They See: Eye Movements and Object Perception Performance in 3-Month-Olds
Peer reviewed Peer reviewed
Direct linkDirect link
Johnson, Scott P.; Slemmer, Jonathan A.; Amso, Dima – Infancy, 2004
A fundamental question of perceptual development concerns how infants come to perceive partly hidden objects as unified across a spatial gap imposed by an occluder. Much is known about the time course of development of perceptual completion during the first several months after birth, as well as some of the visual information that supports unity…
