Four experiments examined how faces compete with physically salient stimuli for the control of attention in 4-, 6-, and 8-month-old infants (N = 117 total). Three computational models were used to quantify physical salience. We presented infants with visual search arrays containing a face and familiar object(s), such as shoes and flowers. Six- and…

Two experiments investigated the role of continuity cues in infants' perception of launching events as causal. Results indicated that younger subjects' perceptions of the particular object may influence perception of causality and that infants' use of cues to causality changes with age. (WP)

Infants were familiarized with plastic animals from one of two categories (land or sea) that were judged similar or variable by adults. Infants were then tested with novel animals from the same or a different category. Thirteen-month-olds in the similar familiarization condition dishabituated to novel animals of a different category and, to a…

Responds to Mandler's critique of authors' view of infant categorization. Maintains that their view of infant categorization is not characterized by a shift from one type of category to another but by gradual changes in the kinds of information infants can use in forming categories. Clarifies position regarding a single categorical process using…

Demonstrates the need for a process-oriented, constructivist approach to understanding infants' categorization abilities. Suggests that emphasizing the distinction between perceptual and conceptual categorization has been an obstacle to forging an approach. Proposes a more microanalytic consideration of features available to infants at different…
