This research examined whether children's construals of mathematical manipulatives -- as toys or as tools for doing mathematics -- influenced their learning from a lesson with the manipulatives. Children (grades 2 and 3) were presented with a set of buckets and beanbags, and they were either given no information about the manipulatives (control)…

Remembering to carry out intended actions in the future, known as prospective memory (PM), is an important cognitive ability. In daily life, individuals remember to perform future tasks that might rely on effortful processes (monitoring) but also habitual tasks that might rely on more automatic processes. The development of PM across childhood in…

In four experiments, we investigate how the ability to detect irrelevant explanations develops. In Experiments 1 and 2, 4- to 8-year-olds and adults rated different types of explanations about "what makes cars go" individually, in the absence of a direct contrast. Each explanation was true and relevant (e.g., "Cars have engines that…

Our ability to shift from current to alternative (e.g., past and future) perspectives (i.e., "self-projection") plays a fundamental role in accurate decision-making. We investigated 3-, 4-, and 5-year-olds' ability to shift perspective to reason about their future and past preferences. In Experiment 1 (N = 96), children were presented…

Millions of children in the United States experience parental incarceration, yet it is unclear how this experience might shape social cognition. We asked children of incarcerated parents (N = 24) and children whose parents were not incarcerated (N = 58) to describe their parents. Both groups of children also rated the extent to which they agree…

The abstract concept of time is conceptualized as moving linearly across space, known as the mental timeline (MTL). The direction of our MTL is consistent with reading direction. English speakers, who read left to right, think of past on the left and future on the right; the reverse is true of Hebrew speakers, who read right to left. However, it…

This study examined how 5- and 9-year-old children (N = 40) produce pantomimes of object use on verbal request. The task required participants to enact an action with an imagined object. Results showed that with age, children (a) proceeded from body part as object to imaginary object and (b) incorporated into their pantomimes more distinctive…

Learning to read is a critical but often challenging academic task for young children. In the current study, we explore the relation between children's reading affect--particularly anxiety--and reading achievement in the early years of reading acquisition. We hypothesized that reading anxiety would relate to reading achievement across the school…

This study examined whether children 4- and 5-years-old (N = 156) can revise a physical science misconception from different types of picture books. A realistic fiction book and informational book with identical images matched in word count and reading difficulty level were compared to a control book about plants. In the pretest and posttest,…

This study examined the extent to which school-aged children's general narrative skills provide cognitive benefits for accurate remembering or enable good storytelling that undermines memory accuracy. European American and Chinese American 6-year-old boys and girls (N = 114) experienced a staged event in the laboratory and were asked to tell a…

It is imperative to identify contextual factors contributing to the development of early math skills, considering their role in later academic achievement. To pursue this goal, the present study investigated the paths connecting parental beliefs and practices during the preschool years to children's numeric skills at the end of kindergarten…

Three experiments explored whether group membership affects the acquisition of richer information about social groups. Employing a minimal-groups paradigm, 6- to 8-year-olds were randomly assigned to 1 of 2 novel social groups. Experiment 1 demonstrated that immediately following random assignment to a novel group, children were more likely to…

Two studies examined inferences drawn about the protagonist's emotional state in movies (Study 1) or audiobooks (Study 2). Children aged 5, 8, and 10 years old and adults took part. Participants saw or heard 20 movie scenes or sections of audiobooks taken or adapted from the TV show Lassie. An online measure of emotional inference was designed…

Determining which dimensions of social classification are culturally significant is a developmental challenge. Some suggest this is accomplished by differentially privileging intrinsic visual cues over nonintrinsic cues (Atran, 1990; Gil-White, 2001), whereas others point to the role of noun labels as more general promoters of kind-based reasoning…

Children are able to distinguish between regular events that can occur in everyday reality and magical events that are ordinarily impossible. How do children respond to a person who brings about magical as compared with ordinary outcomes? In two studies, we tested children's acceptance of informants' claims when the informants had produced either…
