We systematically compared beliefs about animal (e.g., "lion"), artifactual (e.g., "hammer"), and institutional (e.g., "police officer") categories, aiming to identify whether people draw different inferences about which categories are subjective and which are socially constituted. We conducted two studies with 270…

Personal narrative is decontextualized talk where individuals recount stories of personal experience about past or future events. As an everyday discursive speech type, narrative potentially invites parents and children to explicitly link together, generalize from, and make inferences about representations--that is, to engage in higher-order…

Across languages, children produce locative "back" earlier and more frequently than "front," but the reasons for this asymmetry are unclear. On a "semantic misanalysis" explanation, early meanings for "front" and "back" are nonadult (nongeometric), and rely on notions of visibility and occlusion…

Several multivariate models are motivated to answer similar developmental questions regarding within-person (intraindividual) effects between 2 or more constructs over time, yet the within-person effects tested by each model are distinct. In this article, the authors clarify the types of within-person inferences that can be made from each model.…

We investigated whether 12-month-old infants rely on information about the certainty of goal selection in order to predict observed reaching actions. Infants' goal-directed gaze shifts were recorded as they observed action sequences in a multiple-goals design. We found that 12-month-old infants exhibited gaze shifts significantly earlier when…

Four experiments investigated whether infants and adults infer that a novel entity that interacts in a contingent, communicative fashion with an experimenter is itself an intentional agent. The experiments contrasted the hypothesis that such an inference follows from amodal representations of the contingent interaction alone with the hypothesis…

We often need to infer unknown properties of objects from observable ones, just like detectives must infer guilt from observable clues and behavior. But how do inferential processes change with age? We examined young and older adults' reliance on rule-based and similarity-based processes in an inference task that can be considered either a…

Everyday conditional reasoning is typically influenced by prior knowledge and belief in the form of specific exceptions known as counterexamples. This study explored whether adolescents with autism spectrum disorder (ASD; N = 26) were less influenced by background knowledge than typically developing adolescents (N = 38) when engaged in conditional…

Typically developing children understand and predict others' behavior by extracting and processing relevant information such as the logic of their actions within the situational constraints and the intentions conveyed by their gaze direction and emotional expressions. Children with autism have difficulties understanding and predicting others'…

Recent research has suggested that young children have relatively well-developed trait concepts. However, this literature overlooks potential age-related differences in children's appreciation of the fundamentally dimensional nature of traits. In Study 1, we presented 4-, 5-, and 7-year-old children and adults with sets of characters and asked…

Recent research on children's inferencing has found that although adults typically adopt the pragmatic interpretation of "some" (implying "not all"), 5- to 9-year-olds often prefer the semantic interpretation of the quantifier (meaning possibly "all"). Do these failures reflect a breakdown of pragmatic competence or the metalinguistic demands of…

We apply instrumental variables (IV) techniques to a pooled data set of employment-focused experiments to examine the relation between type of preschool childcare and subsequent externalizing problem behavior for a large sample of low-income children. To assess the potential usefulness of this approach for addressing biases that can confound…

Two experiments examined toddlers' ability to use cues to infer meaning of novel action words. Toddlers were taught labels for similar or dissimilar pairs of videotaped actions, with behavioral cues or eye gaze related to agents' intentions distinguishing similar events. Results showed that in year 2, children begin to consider…

Compared gender-related inferences and judgments of third and fifth graders from Taiwan (a traditional collectivistic culture), and Israel (a less traditional modern culture). Found that Taiwanese children distinguished more than did Israeli children between male targets in stories behaving stereotypically and counterstereotypically. Interpreted…
