Young Children's Representations of Spatial and Functional Relations between Objects
Peer reviewed Peer reviewed
Direct linkDirect link
Shutts, Kristin; Ornkloo, Helena; von Hofsten, Claes; Keen, Rachel; Spelke, Elizabeth S. – Child Development, 2009
Three experiments investigated changes from 15 to 30 months of age in children's (N = 114) mastery of relations between an object and an aperture, supporting surface, or form. When choosing between objects to insert into an aperture, older children selected objects of an appropriate size and shape, but younger children showed little selectivity.…

Aligning Body and World: Stable Reference Frames Improve Young Children's Search for Hidden Objects
Peer reviewed Peer reviewed

Perry, Lynn K.; Samuelson, Larissa K.; Spencer, John P. – Journal of Experimental Child Psychology, 2009
This study investigated how young children's increasingly flexible use of spatial reference frames enables accurate search for hidden objects by using a task that 3-year-olds have been shown to perform with great accuracy and 2-year-olds have been shown to perform inaccurately. Children watched as an object was rolled down a ramp, behind a panel…

Limits on Infants' Ability to Dynamically Update Object Representations
Peer reviewed Peer reviewed

Feigenson, Lisa; Yamaguchi, Mariko – Infancy, 2009
Like adults, infants use working memory to represent occluded objects and can update these memory representations to reflect changes to a scene that unfold over time. Here we tested the limits of infants' ability to update object representations in working memory. Eleven-month-old infants participated in a modified foraging task in which they saw…

The Development of Categorical and Coordinate Spatial Relations
Peer reviewed Peer reviewed

Bullens, Jessue; Postma, Albert – Cognitive Development, 2008
Two classes of spatial relations can be distinguished in between and within object representations. Kosslyn [Kosslyn, S. M. (1987). "Seeing and imagining in the cerebral hemispheres: A computational approach." "Psychological Review," 94, 148-175] suggested that the right hemisphere (RH) is specialized for processing coordinate (metric) spatial…

Tracking and Inferring Spatial Rotation by Children and Great Apes
Peer reviewed Peer reviewed
Direct linkDirect link
Okamoto-Barth; Sanae; Call, Josep – Developmental Psychology, 2008
Finding hidden objects in space is a fundamental ability that has received considerable research attention from both a developmental and a comparative perspective. Tracking the rotational displacements of containers and hidden objects is a particularly challenging task. This study investigated the ability of 3-, 5-, 7-, and 9-year-old children and…

Development of Using Experimenter-Given Cues in Infant Chimpanzees: Longitudinal Changes in Behavior and Cognitive Development
Peer reviewed Peer reviewed
Direct linkDirect link
Okamoto-Barth, Sanae; Tomonaga, Masaki; Tanaka, Masayuki; Matsuzawa, Tetsuro – Developmental Science, 2008
The use of gaze shifts as social cues has various evolutionary advantages. To investigate the developmental processes of this ability, we conducted an object-choice task by using longitudinal methods with infant chimpanzees tested from 8 months old until 3 years old. The experimenter used one of six gestures towards a cup concealing food; tapping,…
