Although we cannot see or touch time, across many cultures, we use spatial representations to think about this abstract concept. Spatial representations of time are thought to support temporal concepts that might otherwise be difficult to represent and reason about, such as the temporal component of episodic memory. One common form of spatially…

The recent proliferation of research on children's supernatural concepts is noteworthy, as this work is necessary for a full account of human cognition. Despite this advancement in our field, there is a lingering tendency for scholars to exotify supernatural concepts; to treat them as distinct or special. Arguments have been raised that these…

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…

The development of (early) numerical cognition builds on children's ability to understand and manipulate quantities and numbers. However, previous research did not find conclusive evidence on the role of symbolic and non-symbolic skills in the development of (early) numerical cognition. The aim of the current study was to clarify the relation…

Adults conceptualize God as particularly knowledgeable -- more knowledgeable than humans -- about moral transgressions. We investigated how younger (4- to 5-year-old) and older (6- to 7-year-old) children view God's moral knowledge. Cultural narratives in the United States portray God as omniscient, which could lead children growing up in the…

Research suggests that individual differences in math abilities correlate with approximate representations of quantity that are supported by a primitive Approximate Number System (ANS). However, relatively little research has addressed the direction of this association in early childhood. Here we examined the development of the ANS and math…

This study investigated effects of feedback and exposure to alternative strategies on strategy change in children (N = 106, age range = 7;3-10;0) learning about mathematical equivalence. Children's strategies were evaluated before and after a brief instructional intervention. During the intervention, children either were exposed to a set of 4…

Although infants' cognitions about the world must be influenced by experience, little research has directly assessed the relation between everyday experience and infants' visual cognition in the laboratory. Eye-tracking procedures were used to measure 4-month-old infants' eye movements as they visually investigated a series of…

The present study aims to examine relations between number representations and various sources of individual differences within early stages of development of number representations. The mental number line has been found to develop from a logarithmic to a more linear representation. Sources under investigation are counting skills and executive…

In this article the author describes challenges associated with integrating physiological measures of stress into developmental research, especially in the domains of memory and cognition. An initial critical challenge concerns how to define stress, which can refer to one or a series of events, a response, the consequence of that response, an…

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-…

Habituation of looking time has become the standard method for studying cognitive processes in infancy. This method has a long history and derives from the study of memory and habituation itself. Often, however, it is not clear how researchers make decisions about how to implement habituation as a tool to study processes such as categorization,…

Two experiments investigated how absolute and relative distance shape adults' and young children's ratings concerning the extent to which the term "by" describes the relation between locations. Three- and 4-year-old children and adults were asked to rate how well the word "by" described the relation between several blocks and a landmark. The…

In early childhood, there is a developmental transition in spatial memory biases. Before the transition, children's memory responses are biased toward the midline of a space, while after the transition responses are biased away from midline. The Dynamic Field Theory (DFT) posits that changes in neural interaction and changes in how children…

In "The Foundations of Mind," Jean Mandler describes how perceptual analysis provides a mechanism that allows infants to begin their journey into conceptual life, and subsequently to enter the advanced worlds of conceptual systems, memory, language, and consciousness. This review provides an overview of Mandler's theoretical position, celebrates…
