Peer reviewed Peer reviewed

Bremner, J. Gavin; Slater, Alan M.; Mason, Uschi C.; Spring, Jo; Johnson, Scott P. – Developmental Psychology, 2013
Previous work has demonstrated that infants use object trajectory continuity as a cue to the constant identity of an object, but results are equivocal regarding the role of object features, with some work suggesting that a change in the appearance of an object does not cue a change in identity. In an experiment involving 72 participants, we…

The Role of Local and Distal Landmarks in the Development of Object Location Memory
Peer reviewed Peer reviewed

Bullens, Jessie; Klugkist, Irene; Postma, Albert – Developmental Psychology, 2011
To locate objects in the environment, animals and humans use visual and nonvisual information. We were interested in children's ability to relocate an object on the basis of self-motion and local and distal color cues for orientation. Five- to 9-year-old children were tested on an object location memory task in which, between presentation and…

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)

The Question of Decalage Between Object Permanence and Person Permanence
Peer reviewed Peer reviewed
And Others; Jackson, Elaine – Developmental Psychology, 1978
Presents a study of decalage between object permanence and person permanence. Decalage was influenced by environmental as well as stimulus factors with infants tested between 6- and 81/4-months/of-age. (BD)
