This paper reviews progress over the past 20 years in four areas of research on infant perception and cognition. Work on perception of dynamic events has identified perceptual constraints on perception of object unity and object trajectory continuity that have led to a perceptual account of early development that supplements Nativist accounts.…

Robots and humans receive partial, fragmentary hints about the world's state through their respective sensors. These hints--tiny patches of light intensity, frequency components of sound, etc.--are far removed from the world of objects which we feel and perceive so effortlessly around us. The study of infant development and the construction of…

Understanding how responses become prepotent is essential for understanding when inhibitory control is needed in everyday behaviour. We investigated prepotency in the grass-snow task--in which a child points to a green card when the experimenter says "snow" and a white card when the experimenter says "grass". Experiment 1 (n =…
