This paper estimates the acute effect of community-level homicides on early childhood language development and explores the moderating role of maternal efficacy and satisfaction in Chile. It uses data from the 2017 wave of the Early Childhood Longitudinal Survey of Chilean Children (N = 1194, M[subscript age]: 52.8 months, 52% girls). Children in…

A longitudinal study with 45 children (Hispanic, 13%; non-Hispanic, 87%) investigated whether the early production of non-referential beat and flip gestures, as opposed to referential iconic gestures, in parent-child naturalistic interactions from 14 to 58 months old predicts narrative abilities at age 5. Results revealed that only non-referential…

This study utilized data from the Avon Longitudinal Study of Parents and Children (N = 14,860) to examine whether early-life family income (age 0-5) predicted long-term academic achievement (age 16-18) and to investigate the role of executive function (EF) assessed multiple times across age 7-11 in explaining this association. Task-based EF was a…

Socioeconomic status (SES) and bilingualism have been shown to influence executive functioning during early childhood. Less is known, however, about how the two factors interact within an individual. By analyzing a nationally representative sample of approximately 18,200 children who were tracked from ages 5 to 7 across four waves, both higher SES…

Despite rapidly growing research on parental influences on children's executive function (EF), the uniqueness and specificity of parental predictors and links between adult EF and parenting remain unexamined. This 13-month longitudinal study of 117 parent-child dyads (60 boys; M[subscript age] at Time 1 = 3.94 years, SD = 0.53) included detailed…

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…

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…

Abilities of 2-, 5-, and 7-year-old children to interpret, judge acceptability of, and produce class extensions were assessed. It was concluded that increasing ability to deal appropriately with class extensions is primarily due to general advances in language acquisition rather than to any development unique to the class-extension word-formation…

In two experiments 96 children and eight adults were tested for comprehension of the modifier-head relation in compounds such as apple-knife or were asked to label objects with compounds. Results show that by age three children reliably interpret novel compounds and made use of novel compounds to subcategorize. (RH)

Pooled data from previous studies in which autistic, mentally handicapped, and normal young children had been tested on theory of mind tasks. Found that normal children at a verbal mental age of four years, but autistic children at a verbal mental age of more than nine years, had a 50% chance of passing the theory of mind tests. (BC)

Examined the association of neighborhood characteristics on competencies of Canadian preschoolers. Found that verbal ability positively related to residing in neighborhoods with affluent residents and negatively to residing in neighborhoods with poor residents and in neighborhoods with low cohesion, even after controlling for family SES. Behavior…

A total of 50 children were observed at home at 33 months of age and then tested at 40 months on affective labeling, perspective taking, and false belief tasks. Individual differences at 40 months were associated with family discourse about feelings and causality at 33 months, verbal fluency of mother and child, and sibling cooperation. (BC)
