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…

Temperamental effortful control (EC) and executive functions (EF) are two frameworks for studying self-regulation in children. Despite stemming from different research traditions, they show many conceptual and theoretical similarities and their corresponding tasks are often used interchangeably. However, little is known about how and whether the…

The present study had two aims. First, we set out to evaluate the structure of processing speed in children by comparing five alternative models: two conceptual models (a unitary model, a complexity model) and three methodological models (a stimulus material model, an output response model, and a timing modality model). Second, we then used the…

Picture books inherently contain many parallel dimensions of information and serve as a rich source of input for children. However, studies of children's learning from picture books tend to focus on a single type of information (e.g., novel words). To better understand the learning-related potential of shared book reading, we examined 4.5- to…

Maternal and paternal teaching sequences directed to their preschool children in a naturalistic home environment were investigated. The sample included 37 middle-class sibling dyads, aged four and six, and both their mothers and fathers during ongoing interactions in the home for six 90-minute sessions. Sequences of parent-child teaching were…

There is now wide consensus that the quality of family relationships is involved in the development of child executive functioning (EF), a set of cognitive skills that bear critical importance for social and academic adjustment at school. This body of research has, however, focused almost exclusively on dyadic parent-child interactions and failed…

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…

Pre-algebra mathematical competencies were assessed for a large and diverse sample of sixth graders (n = 1,926), including whole number and fractions arithmetic, conceptual understanding of equality and fractions magnitudes, and the fractions number line. The goal was to determine if there were clusters of students with similar patterns of…

A growing body of research has found a relationship between parenting and the development of executive function in young children; however, fewer studies have examined how parenting is related specifically to the development of working memory. Using data from the Family Life Project, this study examined whether attention was a pathway through…

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…

We explored the role of parental testimony in children's developing beliefs about the ontological status of typically unobservable phenomena. US parents and their 5- to 7-year-old children (N = 25 dyads) separately rated their confidence in the existence of scientific and religious unobservable entities (e.g., germs, angels), and were invited to…

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…

Two studies investigated children's and their parents' reasoning about their mental and bodily states during the time prior to biological conception--"preexistence." Prior research has suggested that, in the absence of a religious script, children display untutored intuitions that they existed as largely disembodied emotional beings…

We examined differences among children in their endorsement of an adult's claim, their subsequent empirical investigation of that claim, and their resolution of any potential conflict between the claim and their empirical investigation. American and Chinese preschool (N = 171, M = 4.71 years) and elementary school (N = 128, M = 7.59 years)…

Parents who vary in their experience with formal schooling are likely to use different types of informal guidance with their children. However, rather than assuming a deficit approach we need evidence regarding how parents with limited schooling support their children's learning. Forty U.S. families of Mexican-heritage, from two levels of…
