Pretend play is an important, universal activity of early childhood, but research to date contains multiple inconsistencies in definitions and measurement of pretend play. To begin to resolve this issue, we conducted a first study of the multiple different behaviors of pretend play in the preschool years (3-5 years), and investigated their…

Within the field of developmental science, there is a general agreement of the need to work together across academic disciplinary boundaries in order to advance the understandings of how to optimize child development and learning. However, experience also shows that such collaborations may be challenging. This paper reports on the experiences of…

We examine the contributions of the environmental context on cognitive development in a representative sample of children (24-59 month-olds) in Nicaragua. Multivariate regression models revealed that children who experienced high levels of structure in the home, encountered more social interaction, and were enrolled in early education programs,…

Translational research involving the development, implementation, and assessment of evidence-based interventions has shown promise in improving outcomes for children from lower socioeconomic-status backgrounds. One such approach involves 2-generation interventions, which target both children and their parents/caregivers. Here we traced the…

Children aged 3 to 8 years old and adults were tested on a reality–fantasy distinction task. They had to judge whether particular entities were real or fantastical, and response times were collected. We further manipulated whether the entity is a specific character or a generic fantastical entity. The results indicate that children, unlike adults,…

A series of studies investigated White U.S. 3- and 4-year-old children's use of gender and race information to reason about their own and others’ relationships and attributes. Three-year-old children used gender- but not race-based similarity between themselves and others to decide with whom they wanted to be friends, as well as to determine which…

Object use is a ubiquitous characteristic of the human species, and learning how objects function is a fundamental part of development. In this article the authors examine the role that intentionality plays in children's understanding of causal relationships during observational learning of object use. Children observed demonstrations in which…

In this study, the authors assessed children's ability to use information overheard in other people's conversations to judge the reality status of a novel entity. Three- to 9-year-old children (N = 101) watched video clips in which two adults conversed casually about a novel being. Videos contained statements that explicitly denied, explicitly…

By preschool age, children have a sophisticated assumption about the conventional nature of various kinds of information. The present studies investigated the role of two cues in 2- and 3-year-olds' determination of what is conventional, namely the intentionality and intra-individual consistency in the use of objects. Overall, in Study 1, both 2-…

We test whether comparison can promote learning of new relational abstractions. In Experiment 1, preschoolers heard labels for novel spatial patterns and were asked to extend the label to one of two alternatives: one sharing an object with the standard or one having the same relational pattern as the standard. Children strongly preferred the…

The relationship between emergent spatial understanding in different cognitive domains, including navigation and language, has rarely been studied using methods that allow for the examination of individual differences. In this study the authors explored emergent place learning and its relationship to early spatial language, namely prepositions, in…

When learning object function, infants must detect relations among features--for example, that squeezing is associated with squeaking or that objects with wheels roll. Previously, Perone and Oakes (2006) found 10-month-old infants were sensitive to relations between object appearances and actions, but not to relations between appearances and…

Longitudinal data analysis has long played a significant role in empirical research within the developmental sciences. The past decade has given rise to a host of new and exciting analytic methods for studying between-person differences in within-person change. These methods are broadly organized under the term "growth curve models." The…

We examined how maternal strategic behaviors during a mother-child collaborative sort-recall task of categorically similar items related to children's recall and children's strategic behavior in a sort-recall task that they completed independently. Mother-child dyads participated in the collaborative sort-recall task when children were 40 months…

A method for eliciting extended explanations was used to evaluate predictions from the "theory-theory" account of developing psychological reasoning. Children were repeatedly asked to explain the actions or emotions of story characters with false beliefs. Questioning elicited false belief attributions in half of 3-year-olds (Study 1, N = 16, age M…
