Human infants develop a variety of attentional mechanisms that allow them to extract relevant information from a cluttered multimodal world. We know that both social and nonsocial cues shift infants' attention, but not how these cues differentially affect learning of multimodal events. Experiment 1 used social cues to direct 8- and 4-month-olds'…

Accounts of learning and generalization typically focus on factors related to lasting changes in representation (i.e., long-term memory). The authors present evidence that shorter term effects also play a critical role in determining performance and that these recency effects can be subdivided into perceptual and decisional components.…

The purpose of this study was to investigate, both empirically and theoretically, the manner in which human Ss (might) learn to estimate relative frequencies of nine different outcomes of an uncertain event on the basis of a random sequence of event occurences. (Author)
