Asserts that theory of mind is unique to humans and that its original function was to provide a more abstract level of describing ancient behavioral patterns, such as deception, reconciliation, and gaze following. Suggests that initial selective advantage of theory of mind may have been increased flexibility of already-existing behaviors, not…

Maintains that the results of Wellman, Cross, and Watson's meta-analysis on the false belief task are perfectly compatible with "early competence" accounts that posit a specific, innate, and possibly modular basis for theory of mind. Asserts that Wellman and colleagues' arguments against such views stem from mistaken assumptions regarding the…

Maintains that authors' meta-analytic findings make early competence accounts of theory of mind increasingly unlikely. Asserts that findings argue against executive function expression accounts, including that advocated by Scholl and Leslie (PS532407). Explains that meta-analytic findings directly contradict Scholl and Leslie's predictions…

Two studies investigated whether 10- to 11-month-olds possess skills for parsing ongoing behavior along boundaries correlated with initiation and completion of intentions. Found that infants showed renewed interest in test videos in which motion paused in the midst of an actor's pursuit of intentions; suspended motion at intentional boundary…

Examined in two studies referential understanding in 12- and 18-month-olds' responses to another's emotional outburst. Found that infants relied on the presence versus absence of referential cues to determine whether an emotional message should be linked with a salient object and they actively consulted referential cues to disambiguate the…

Examined the predictive validity of urban first-graders' self-reports of depressed mood and feelings with respect to later psychopathology and adaptive functioning. Found that subjects' self-reports of depressed mood predicted later academic functioning, the need for and use of mental health services, suicidal ideation, and major depressive…

Examined contributions of dimensions of maternal responsiveness to timing of milestones in early expressive language development. Found that maternal responsiveness at 9 and 13 months predicted timing of language milestones over and above children's observed behaviors. Responsiveness at 13 months was a stronger predictor of timing than…

Four studies compared preschoolers' fast mapping of new proper and common names following indirect exposures requiring inference with their learning new names following ostensive cues. Found that inferential learning of names and learning by direct instruction were largely equivalent: learning from a situation with clear joint references…

Examined how Japanese 2- and 4-year-olds assigned meaning to novel nouns associated with familiar and unfamiliar animals and inanimate objects. Found that in the absence of useful information from syntax, the 2-year-olds were able to fast map a noun to its meaning by elegantly coordinating word-learning biases and other available sources of…

Explored in 2 studies 3- and 4-year-olds' understanding that the 5 senses can each lead to different types of knowledge. Found that 3-year-olds performed significantly poorer than 4-year-olds on all tasks, suggesting a marked transition in children's ability to recognize the origin of their modality-specific knowledge between 3 and 4 years.…

Preschoolers at high or low family risk for reading disability (RD) were evaluated yearly from preschool through second grade. Findings indicated that participants who became RD showed deficits in phonological skills at all time points. Both risk groups underwent a similar--though not simultaneous-- developmental shift from letter-name knowledge…

Explored in three experiments children's understanding of emotion in speech. Found gradual developmental change from 4-year-olds' focus on content to adult's focus on paralanguage. Children exhibited greater response latencies to utterances with conflicting cues than to those with nonconflicting cues. They accurately labeled affective paralanguage…

Examined the relationship between age and the normative/descriptive gap--the discrepancy between actual reasoning and traditional standards for reasoning. Found that middle adolescents performed closer to normative ideals than early adolescents. Factor analyses suggested that performance was based on two processing systems, analytic and heuristic…

Assessed friendships among Head Start preschoolers. Found that older children were more likely than younger children to participate in a reciprocated friendship, and reciprocated dyads were more likely to be same-gender than were nonreciprocated dyads. Reciprocated friends interacted more frequently and looked at each other more than…

Examined children's internal representations of peer interactions. Found that children as young as preschool-age rate typical boys as preferring group interactions more than typical girls, more likely than girls to be friends with one another if they are friends with the same target boy or girl, respectively; and as less likely than girls to know…
