Cacchione, Trix; Call, Josep – Cognition, 2010
Recent research suggests that witnessing events of fission (e.g., the splitting of a solid object) impairs human infants', human adults', and non-human primates' object representations. The present studies investigated the reactions of gorillas and orangutans to cohesion violation across different types of fission events implementing a behavioral…

Cacchione, Trix; Call, Josep – Developmental Science, 2010
We investigated whether great apes, like human infants, monkeys and dogs, are subject to a strong gravity bias when tested with the tubes task, and--in case of mastery--what the source of competence on the tubes task is. We presented 22 apes with three versions of the tubes task, in which an object is dropped down a tube connected to one of three…

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…

Charles, Eric P.; Rivera, Susan M. – Developmental Science, 2009
Piaget proposed that understanding permanency, understanding occlusion events, and forming mental representations were synonymous; however, accumulating evidence indicates that those concepts are "not" unified in development. Infants reach for endarkened objects at younger ages than for occluded objects, and infants' looking patterns suggest that…

Jeanne L. Shinskey; Yuko Munakata – Developmental Science, 2010
Novelty seeking is viewed as adaptive, and novelty preferences in infancy predict cognitive performance into adulthood. Yet 7-month-olds prefer familiar stimuli to novel ones when searching for hidden objects, in contrast to their strong novelty preferences with visible objects (Shinskey & Munakata, 2005). According to a graded representations…

Luo, Yuyan; Johnson, Susan C. – Developmental Science, 2009
The present research examined whether infants as young as 6 months of age would consider what objects a human agent could perceive when interpreting her actions on the objects. In two experiments, the infants took the agent's actions of repeatedly reaching for and grasping one of two possible objects as suggesting her preference for that object…

Gliga, Teodora; Volein, Agnes; Csibra, Gergely – Journal of Cognitive Neuroscience, 2010
Whether verbal labels help infants visually process and categorize objects is a contentious issue. Using electroencephalography, we investigated whether possessing familiar or novel labels for objects directly enhances 1-year-old children's neural processes underlying the perception of those objects. We found enhanced gamma-band (20-60 Hz)…

Marcovitch, Stuart; Zelazo, Philip David – Developmental Science, 2009
The hierarchical competing systems model (HCSM) provides a framework for understanding the emergence and early development of executive function--the cognitive processes underlying the conscious control of behavior--in the context of search for hidden objects. According to this model, behavior is determined by the joint influence of a…

O'Hearn, Kirsten; Hoffman, James E.; Landau, Barbara – Developmental Science, 2010
The ability to track moving objects, a crucial skill for mature performance on everyday spatial tasks, has been hypothesized to require a specialized mechanism that may be available in infancy (i.e. indexes). Consistent with the idea of specialization, our previous work showed that object tracking was more impaired than a matched spatial memory…

Huttenlocher, Janellen – American Psychologist, 2008
The ability to locate objects in the environment is adaptively important for mobile organisms. Research on location coding reveals that even toddlers have considerable spatial skill. Important information has been obtained using a disorientation task in which children watch a target object being hidden and are then blindfolded and rotated so they…

Cuevas, Kimberly; Bell, Martha Ann – Developmental Psychology, 2010
From a neuropsychological perspective, the cognitive skills of working memory, inhibition, and attention and the maturation of the frontal lobe are requisites for successful A-not-B performance on both the looking and reaching versions of the task. This study used a longitudinal design to examine the developmental progression of infants'…

Mahajan, Neha; Barnes, Jennifer L.; Blanco, Marissa; Santos, Laurie R. – Developmental Science, 2009
Both human infants and adult non-human primates share the capacity to track small numbers of objects across time and occlusion. The question now facing developmental and comparative psychologists is whether similar mechanisms give rise to this capacity across the two populations. Here, we explore whether non-human primates' object tracking…

Nardini, Marko; Atkinson, Janette; Burgess, Neil – Cognition, 2008
In previous studies, children disoriented in small enclosures used room shape, but not wall colors, to find hidden objects. Their reorientation was said to depend solely on a "geometric module" informationally encapsulated with respect to color. We argue that previous studies did not fully evaluate children's use of color owing to a bias in the…

Bruce, Susan; Muhammad, Zayyad – International Journal of Disability, Development and Education, 2009
This article presents a review of the literature on object permanence with an emphasis on research on children with severe disabilities. Object permanence is the realisation that objects continue to exist in time and place even when they are no longer visible. This understanding is achieved across Stages IV-VI of Piaget's Sensorimotor Period.…

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.…
