The relationship between motor skills and executive functions (EFs) is gaining prominence in the field of developmental psychology. However, evidence of the motor skills--EFs link in children with typical development is somewhat inconsistent and there has been no adequate attempt to evaluate it systematically across studies. In view of this, the…

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…

As children get older, they become better able to discriminate between impossible and improbable statements and they realize that improbable events can occur in reality while impossible ones cannot. However, when children hear about extraordinary events from fictional entities (e.g., popular characters from children's media), they may be more…

Although laboratory studies have examined the development of children's prospective memory (PM) and the factors that influence its performance, much less is known about children's PM performance and development in their everyday life. The current study used an online parent diary report approach to examine American 2- to 6-year-olds' PM successes…

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…

A live video was used to study the development of visual self-recognition in a cross-sectional sample of 152 typically developing French children aged between 15 months to 6 years. Three reactions to a mark placed on the child's cheek without their knowledge were studied: the touch of the mark with their hand, the ocular responsiveness to the mark…

Children tend to select a novel object rather than a familiar object when asked to identify the referent of a novel label. Current accounts of this so-called "disambiguation effect" do not address whether children have a general metacognitive representation of this way of determining the reference of novel labels. In two experiments…

Children learn about the world through others' testimony, and much of this knowledge likely comes from parents. Furthermore, parents may sometimes want children to share their beliefs about topics on which there is no universal consensus. In discussing such topics, parents may use explicit belief statements (e.g., "Evolution is real") or…

This research investigates the development of constraints in word learning. Previous experiments have shown that as infants gain more knowledge of native language structure, they become more selective about the forms that they accept as labels. However, the developmental pattern exhibited depends greatly on the way that infants are introduced to…

Understanding executive functions (EFs) development is of high value to global developmental science. Recent calls for a more inclusive and equitable developmental science argue that tasks and questionnaires that are developed using only a subset of the population are not likely to be appropriate for EFs measurement in global contexts unless…

Spatial play in early childhood is associated with a variety of spatial and cognitive skills. However, these associations are often derived from studies in which different tasks are used across different age ranges, leaving open the question of how children's natural behaviors during spatial play develop from infancy into the early preschool…

Numerous studies suggest that by elementary school, children have implicit and explicit gender stereotypes about the toys, activities, roles, and abilities associated with boys vs. girls. Furthermore, these stereotypes have been shown to affect children's goals and behaviors, leading them to pursue activities that are associated with their own…

This study investigated developmental differences in metacognitive monitoring and control in younger (5- to 6-year-old) and older (8- to 10-year-old) children's prospective memory (PM). Metacognitive monitoring was assessed by asking the children to judge their performance before (prediction) and after (postdiction) performing a resource-demanding…

This experiment tests the age at which left-to-right spatial associations found in infancy shift to culture-specific spatial biases in later childhood, for both numerical and non-numerical information. Children ages 1-5 years (N = 320) were tested within an eye-tracking paradigm which required passive viewing of a video portraying a spatial…

Question asking plays a fundamental role in learning, and the cognitive development literature contains many studies of specific types of question-asking skills. However, little is known about the developmental course across different aspects of question asking, of which we explore: (a) the ability to ask questions that enable children to solve a…
