What was that? The development of visual working memory in infants Zsuzsa Kaldy Infant Cognition Lab Department of Psychology University of Massachusetts at Boston How do infants represent objects? Research in the past two decades has shown that infants’ knowledge about their physical world is surprisingly rich. In this talk, I will discuss some of these studies, with a focus on the early processing of perceptual features. How can infants tell if a particular object that they are seeing is the same one that they saw before? I will show that young infants remember some features of objects but not others, and present some hypotheses about why such differences occur.
