Do children think of genetic inheritance as deterministic or probabilistic? In two novel tasks, children viewed the eye colors of animal parents and judged and selected possible phenotypes of offspring. Across three studies (N = 353, 162 girls, 172 boys, 2 non-binary; 17 did not report gender) with predominantly White U.S. participants collected…

Learning environments can support the development of foundational knowledge and promote children's attitudes toward learning and school. This study explores the relation between school enjoyment and general knowledge from preschool (2016-2017) to kindergarten (2017-2018) in 1359 children (M[subscript age] = 55, 61 months, female = 50%; 58.5%…

Scientists have long employed puppets in research with young children; this essay explores the validity of this practice. After considering what puppets are, their main types and history, I note the different ways puppets have been employed in research. One of these uses raises the issue of whether and when children apply their theory of mind to…

We investigated how gender is represented in children's books using a novel 200,000 word corpus comprising 247 popular, contemporary books for young children. Using human judgments and word co-occurrence data, we quantified gender biases of words in individual books and in the whole corpus. We find that children's books contain many words that…

This study investigated whether transitory and persistent poverty spells were associated with children's learning (literacy and numeracy scores) and executive function outcomes in Ghana. Children resided in the Greater Accra region (N = 2,154; 49% female; M[subscript age] = 5.2 years at wave-1) and were followed at four-time points over three…

Purpose: Systematic reviews of literature are routinely conducted to identify practices that are effective in addressing educational and clinical problems. One complication, however, is how best to combine data from both group experimental design (GED) studies and single-case experimental design (SCED) studies. Percent of Goal Obtained (PoGO) has…

Children's storybooks often contain fantasy elements, from dragons and wizards to anthropomorphic animals that wear clothes, talk, and behave like humans. These elements can impact children's learning from storybooks both positively and negatively, perhaps due in part to their ability to capture children's interest and attention. Prior research…

In the target article, Xing and colleagues (2021) claimed that 6- to 8-year-olds who spontaneously referenced the midpoint of 0-100 number lines made more accurate magnitude estimates and scored higher on a standardized math achievement test than other children. Unlike previous studies, however, the authors found no relation between accuracy on…

We investigated the impact of a subsidized, needs-based preschool program (Study 1; N = 1,894) and California's universal but age-restricted transitional kindergarten (TK) program (Study 2; N = 1,093) on school readiness. We applied Mahalanobis matching--a quasi-experimental data analysis method used to create equivalent groups--to data from three…

There is scant empirical work on associations between current and past cannabis use in parents of young children. As recreational cannabis use is now legal in nearly half of states in the U.S., cannabis use is becoming more ubiquitous. In the current study, parents of toddler and pre-school age children were randomly assigned to participate in an…

This article compares findings from two national surveys of remote learning for children 2-5 years old during school year one (2019-2020) of the COVID-19 pandemic to school year two (2020-2021) of the COVID-19 pandemic. The refined survey contains 45 closed-ended and five open-ended items covering seven domains: (a) demographic information; (b)…

Biobehavioral frameworks of attachment posit that mother-child dyads engage in physiological synchrony that is uniquely formative for children's neurobiological, social, and emotional development. Much of the work on mother-child physiological synchrony has focused on respiratory sinus arrhythmia (RSA). However, the strength of the existing…

Contemporary discussions around gender roles, stereotypes, and play highlight the need for updated research on the influences of children's early play experiences and learning (Weisgram, 2018). Different types of play relate to different skills and vary by gender, such as spatial play and spatial skill (Jirout & Newcombe, 2015; Voyer, Voyer,…

Children's understanding of death has been a topic of interest to researchers investigating the development of children's thinking and clinicians focusing on children's coping with the death of a loved one. Traditionally, researchers in cognitive development have mainly focused on death from a biological perspective. Current research suggests that…

In this paper, we decompose selective sustained attending behavior into components of continuous attention maintenance and attentional transitions and study how each of these components develops in young children. Our results in two experiments suggest that changes in children's ability to return attention to a target locus after distraction…
