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…

Developmental research suggests that whereas very young infants individuate objects purely on spatiotemporal grounds, from (at latest) around 1 year of age children are capable of individuating objects according to the kind they belong to and the properties they instantiate. As the latter ability has been found to correlate with language, some…

An extensive body of research claims that labels facilitate categorisation, highlight the commonalities between objects and act as invitations to form categories for young infants before their first birthday. While this may indeed be a reasonable claim, we argue that it is not justified by the experiments described in the research. We report on a…

This study examined infants' use of object knowledge for scaling the manipulative force of object-directed actions. Infants 9, 12, and 15 months of age were outfitted with motion-analysis sensors on their arms and then presented with stimulus objects to examine individually over a series of familiarization trials. Two stimulus objects were used in…

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…

Intended to assist teachers as they assess, plan for, and teach deaf blind students, this manual describes a process for adapting curricula for students who function within the 0-24 month developmental period, also known as the sensorimotor period. The manual's first section provides an overview of project activities including the literature…
