Examines infants' ability to detect correlations among feature categories of the type that one might expect to be useful in forming natural object categories. (PCB)

Uses a nonsimultaneous pulsation threshold technique to examine the development of frequency resolutions in infants of three to six months. (PCB)

Finds support for the global trend hypothesis which posits that cognitive processing speed changes as a function of age and all component processes change at the same rate. (PCB)

Twenty-four preschool-age girls repeatedly experienced an initially novel episode in a laboratory setting. Each child's knowledge of the episode was assessed in an effort to examine the development of the children's scripts for a recurring event. (PCB)

The importance of actions, results, and instruments in the development of verb concepts was examined in four studies. Studies are discussed in terms of theory and research on conceptual development, word learning strategies, and the semantic organization of nouns and verbs. (PCB)

Investigated four to six year olds' understanding of cognitive cuing in two experiments that used a strategic interaction paradigm. (PCB)

Two experiments were conducted in an effort to determine whether young children overestimate message quality because they evaluate their knowledge or assumptions about the intended meaning of the message rather than its literal meaning. (PCB)

Children were interviewed about their conceptions of good listening, beliefs about appropriate actions for confused listeners, attributions of responsibility for a listener's confusion, reports of speakers' and listeners' feelings during communication breakdown, and ability to detect inconsistencies during a comprehension-monitoring task. (PCB)

Two studies showed that children of about four years of age had begun to understand that beliefs may be held with differing degrees of certainty. This understanding was tied to the children's understanding of the nature of beliefs and the distinction between appearance and reality. (PCB)

In the two studies reported, three year olds tended to choose mentalistic descriptions more often than behavioral ones to describe people. (PCB)

Considers aspects of the structural design of conventions observed in parent-child interaction. Examines kinds of design differences that occur in conventions and the consequences of those differences, particularly for parent-child coordination. (PCB)

Uses the still-face paradigm as a framework for examining the range of social regulatory capacities available to infants during stressful times. (PCB)

Examined mothers' and infants' affect in play and infant sex as predictors of infants' response to the still-face situation. (PCB)

Examined whether young infants produced differentially organized hand and arm actions in relation to affective expressions when the infants were presented with social and nonsocial stimuli. (PCB)

Infants participated in a nonsocial contingency task immediately after a social interaction with their mothers. The amount of time mothers and infants spent in a state of vocal turn-taking predicted individual differences in infants' subsequent performance on the contingency task. (PCB)
