Children's math learning (N = 217; M[subscript age] = 4.87 years; 63% European American, 96% college-educated families) from an intelligent character game was examined via social meaningfulness (parasocial relationships [PSRs]) and social contingency (parasocial interactions, e.g., math talk). In three studies (data collected in the DC area:…

Using data from a nationally representative sample of 5-year-olds in the Growing Up in Ireland study (N = 9001, 51% male), this research investigated the role of factors in the neighborhood environment on levels of active outdoor play in young children. Primary caregivers (98% mothers; 81% Irish) responded to questions regarding their child's…

We examined 6- to 9-year-olds' (N = 60, 35 girls, 34% White, 23% Hispanic, 2% Black/African American, 2% Asian/Asian American, 22% Mixed Ethnicity/Race, 17% Unavailable, collected April-September 2019 in Providence, RI, USA) first-person perspectives on their exploration of museum exhibits. We coded goal setting, goal completion, and behaviors…

This study examined parent-child math talk within three contexts (formal learning; guided play; unguided play) in order to identify characteristics of activities supporting high-quality math engagement. Seventy-two dyads of parents and 4- and 5-year-olds were observed using a set of toy foods; instructions and materials varied across conditions.…

Theorists have speculated about the symbolic underpinnings of theory of mind (ToM), but no study has examined them across the main developmental span of ToM. Here, the onset of symbolic understandings in three domains (pretend play, language, and understanding representations) and ToM was examined. Fifty-eight children were tested on batteries of…

Can young children, forming expectations about the social world, capture differences among people without falling into the pitfalls of categorization? Categorization often leads to exaggerating differences between groups and minimizing differences within groups, resulting in stereotyping. Six studies with 4-year-old children (N = 214)…

Many studies have examined associations between children's theory of mind and social behavior with familiar peers, but to date none have examined how theory of mind might relate to behavior toward unfamiliar peers in a play setting. Forty-four 4-year-olds (21 girls, 23 boys) participated in standard theory-of-mind tasks and in a play session with…

Relations among indices of maternal mind-mindedness (appropriate and nonattuned mind-related comments) and children's: (a) internal state vocabulary and perspectival symbolic play at 26 months ("N" = 206), and (b) theory of mind (ToM) at 51 months ("n" = 161) were investigated. Appropriate comments were positively…

A key prediction of cognitive theories of gender development concerns developmental trajectories in the relative strength or rigidity of gender typing. To examine these trajectories in early childhood, 229 children (African American, Mexican American, and Dominican American) were followed annually from age 3 to 5 years, and gender-stereotypical…

In one of the first open diffusion experiments with young children, a tool-use task that afforded multiple methods to extract an enclosed reward and a child model habitually using one of these methods were introduced into different playgroups. Eighty-eight children, ranging in age from 2 years 8 months to 4 years 5 months, participated. Measures…

In line with theories that children's pretend play reflects and extends their narrative skills, children with imaginary companions were predicted to have better narrative skills than children without imaginary companions. Forty-eight 5 1/2-year-old children and their mothers participated in interviews about children's imaginary companions.…

This study on sensitivity and attachment included 55 toddlers and their parents. Samples included children with autism spectrum disorder (ASD), mental retardation, language delay, and typical development. Children were diagnosed at 4 years of age. Two years before diagnosis, attachment was assessed with the Strange Situation procedure, and…

Parental responses to grammatically correct and incorrect child utterances were observed in free-play interactions of two groups, each containing 10 parents and their language learning children. Group 1: 21-26 months old, with MLU's between 2 and 2.5 morphemes. Group 2: 34-40 months old, with MLU's between 3 and 3.5 morphemes. (Author/BN)

Concludes that the movement from parallel play to group play may be more a matter of minutes that months. For the 41 children observed, who ranged in age from 32 to 42 months, parallel play often functioned in the stream of activities as a bridge to group play. (Author/RH)

Normal and mentally retarded children were attentive to adults who showed distress, fear, and discomfort. Autistic children looked at adults less and engaged in more toy play than other children when adults pretended to be hurt. Autistic children were less attentive than normal children to adults who showed fear. (BC)
