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…

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…

Shutts, Kristin; Keen, Rachel; Spelke, Elizabeth S. – Developmental Science, 2006
Previous research has shown that young children have difficulty searching for a hidden object whose location depends on the position of a partly visible physical barrier. Across four experiments, we tested whether children's search errors are affected by two variables that influence adults' object-directed attention: object boundaries and…

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…

Barringer, M. D.; Kosal-Smither, C. – 1982
A resource and activity guide for the developmentally disabled that focuses on methods to teach students skills essential to learning is presented. It is noted that once students begin to acquire these critical skills, they can become active participants in group learning activities, rather than waiting for their turn in individual sessions. They…
