Recently, there have been calls to build a more inclusive knowledge base of the home numeracy environment (HNE) by diversifying the populations in our descriptive research. Given that Latine children are the fastest-growing population in the U.S. it is of the utmost importance to include Latine families and children in these efforts. The present…

The aim of this study was to summarize evidence about the relations between parent math support in children aged 3-5 years (from several countries in America, Asia, and Europe) and concurrent and longitudinal math outcomes. The (bio)ecological model of human development guided our hypotheses. The design and reporting of this meta-analysis used the…

The present study examined patterns of number-related utterances and actions directed to 9-month-old infants by their parents. An ethnically and economically diverse sample of 86 families participated in structured play sessions conducted separately with the mothers and fathers of each infant. Data were coded for eight math talk categories, and…

This research investigates positive future expectancies, particularly hope in children, which is comprised of agency thinking, perceiving oneself as capable of achieving goals, and pathways thinking, perceiving oneself as capable of discovering methods toward the desired goals. Two studies (n = 82) were conducted in the United States to examine…

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…

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…

Differences in children's math knowledge emerge as early as the start of kindergarten, and persist throughout schooling. Previous research implicates the importance of early parent number talk in the development of math competency. Yet we understand little about the factors that relate to variation in early parent number talk. The current study…

Recent research has highlighted the critical role in children's cognitive development of the metacognitive support parents give their children during everyday interactions. Our main goal was to examine whether parents made consistent use of metacognitive talk across different parent - child interaction contexts and to document the effect of this…

Infants begin to produce abstract "math" words -- such as numbers (e.g., "two"), spatial terms (e.g., "down"), and magnitude words (e.g., "more") -- during their second postnatal year. Math words, as all words, are likely learned in the home setting during interactions with caregivers. However, everyday…

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…

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…

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…

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…

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…

A growing body of literature has established longitudinal associations between key social cognitive capacities emerging in infancy and children's subsequent theory of mind. However, existing work is limited by modest sample sizes, narrow infant measures, and theory of mind assessments with restricted variability and generalizability. The current…
