Needham, Amy; Goldstone, Robert L.; Wiesen, Sarah E. – Cognitive Science, 2014
How does perceptual learning take place early in life? Traditionally, researchers have focused on how infants make use of information within displays to organize it, but recently, increasing attention has been paid to the question of how infants perceive objects differently depending upon their recent interactions with the objects. This experiment…

Ganea, Patricia A.; Harris, Paul L. – Child Development, 2010
This research examined the ability of young (N = 96) children to learn about a change in the location of a hidden object, either via an adult's verbal testimony or from direct observation. Thirty-month-olds searched with equal accuracy whether they were told about the change or directly observed it. By contrast, when 23-month-olds were told about…

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…

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…

Blaye, Agnes; Jacques, Sophie – Developmental Science, 2009
The current study evaluated the relative roles of conceptual knowledge and executive control on the development of "categorical flexibility," the ability to switch between simultaneously available but conflicting categorical representations of an object. Experiment 1 assessed conceptual knowledge and executive control together; Experiment 2…

Baillargeon, Renee – Developmental Psychology, 1987
Three experiments test object permanenece in 3 1/2- and 4 1/2-month-old infants, and use an impossible-possible-habituation event format. The 4 1/2-month-olds, and the 3 1/2-month-olds who were fast habituators, look reliably longer at the impossible than at the possible event. Results seriously question Piaget's (1954) claims regarding the age at…

Deocampo, Joanne Agayoff; Hudson, Judith A. – Journal of Cognition and Development, 2005
Research on children's understanding of video has shown seeming contradictions. Fourteen-month-olds imitate actions seen on TV (Meltzoff, 1988) and 18-month-olds are reminded of an event by watching video (Sheffield & Hudson, 2003) but 24-month-olds fail at a video-mediated object-retrieval task requiring dual representational understanding…

Cossette-Ricard, Marcelle; Gouin Decarie, Therese – 1983
A series of studies focused on (1) the evolution of the notion of identity of objects among infants up to 15 months of age and (2) the changing rules by which this development may be understood. Six identity tasks were presented to 60 infants divided into five age groups: 5, 7, 9, 12, and 15 months. Two objects were used in all tasks. In the first…

Wishart, Jennifer G. – Child Development, 1986
Investigates whether 6- to 12-month-old infants' exposure to the successful search behavior of a sibling in two object-concept tasks would enhance infants' subsequent performance on these tasks. (HOD)

Sophian, Catherine; Wellman, Henry M. – Journal of Experimental Child Psychology, 1983
Experiment one tested 9- and 16-month-old children on a modification of Piaget's Stage IV object permanence task, examining infants' use of information from previous experiences with an object and from a recent hiding to locate a hidden object. In experiment two, two-, two-and-a-half-, and four-year-old children additionally received verbal…

Karlan, George R. – Journal of the Association for the Severely Handicapped (JASH), 1980
Findings indicated that (1) stable preference measures could be obtained, (2) high preference objects resulted in higher motivation to perform and hence higher levels on each scale, (3) performance of this population is not stable, and (4) ordinality was violated in nearly 20 percent of the administrations of the scales.

Baillargeon, Renee; DeVos, Julie – Child Development, 1991
Observed the reactions of 3.5-month-old infants looking at a carrot that should have but did not appear in a window after passing behind a screen. The results of this and several similar experiments indicated that 3.5-month-old infants are able to represent and reason about hidden objects. (BC)

Campos, Joseph J.; Ramsay, Douglas S. – Developmental Psychology, 1978
Attempts to determine whether infants' performance in two search tasks is related to their entry into Stage 6 of object permanence development (thereby testing Piaget's claim that only Stage 6 infants possess the capacity for representation). (BD)

Ahmed, Ayesha; Ruffman, Ted – Developmental Psychology, 1998
Four experiments examined 8- to 12-month olds on search and nonsearch A not B tasks, a one-location task, and control tasks. Results indicated memory for where object was hidden and expectations of where it should be found. The effect occurred at delays at which infants made the A not B error when searching, and at a longer 15-second delay.…

Carey, Susan; Xu, Fei – Cognition, 2001
Examines evidence that the research community studying infants' object concept and the community concerned with adult object-based attention have been studying the same natural kind. Maintains that the discovery that the object representations of young infants are the same as the object files of mid-level visual cognition has implications for both…
