Perraudin, Sandrine; Mounoud, Pierre – Developmental Science, 2009
We conducted three experiments to study the role of instrumental (e.g. "knife-bread") and categorical (e.g. "cake-bread") relations in the development of conceptual organization with a priming paradigm, by varying the nature of the task (naming--Experiment 1--or categorical decision--Experiments 2 and 3). The participants were 5-, 7- and…

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…

Booth, Amy E.; Waxman, Sandra R. – Developmental Science, 2008
In this paper we consider the perceptual and conceptual contributions that shape early word learning, using research on the "shape bias" as a case in point. In our view, conceptual, linguistic, social-pragmatic, and perceptual sources of information influence one another powerfully and continuously in the service of word learning throughout…

Perry, Lynn K.; Smith, Linda B.; Hockema, Stephen A. – Developmental Science, 2008
Recent research has shown that 2-year-olds fail at a task that ostensibly only requires the ability to understand that solid objects cannot pass through other solid objects. Two experiments were conducted in which 2- and 3-year-olds judged the stopping point of an object as it moved at varying speeds along a path and behind an occluder, stopping…

Uttal, David H.; Fisher, Joan A.; Taylor, Holly A. – Developmental Science, 2006
People acquire spatial information from many sources, including maps, verbal descriptions, and navigating in the environment. The different sources present spatial information in different ways. For example, maps can show many spatial relations simultaneously, but in a description, each spatial relation must be presented sequentially. The present…
