This study aimed to determine whether there is a correlation between maternal conversational participation and the unconventional language of autistic children, and whether the relative vocabulary diversity between mother and child would affect the relationship between them. Participants were 39 autistic Mandarin-speaking children, aged 3-6 years,…

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…

Language abilities in early childhood show stability over time and play an important role in the development of other cognitive processes. Identifying modifiable environmental risk factors is important to informing prevention and early intervention efforts. Maternal verbal ability has been previously linked to child verbal ability. The current…

We examined the relations between mothers' reading skills, home literacy environment (HLE), and children's emergent literacy skills and word reading and whether their relations vary across urban and rural contexts in China. Four hundred third-year kindergarten Chinese children (M[subscript age] = 74.50 ± 3.77 months) were recruited from Jining (N…

Hypothalamic-Pituitary-Adrenal (HPA) axis activity is related to negative mental health outcomes, including depression. Most developmental research uses salivary cortisol to index HPA activity; however, hair cortisol concentrations (HCCs) reflect cortisol production over extended periods of time. While HCCs have been linked to adult depression,…

This study investigated the contribution of fine and gross motor skills to academic and attentional performance at school entry among 832 boys and girls. Children were tested on their fine and gross motor skills (locomotor, object control) and their academic performance in receptive vocabulary, number knowledge, and attentional skills at 6 to 7…

The present study examined the dyadic nature of fathers' and mothers' reported frequency of storybook reading by testing (1) the longitudinal association in parents' frequency of storybook reading when their children were 10.47 months old and 52.95 months old, (2) the interdependence between both parents' reported frequency of storybook reading,…

Effects of child and environmental factors in moderating the course of bilingual development were investigated using longitudinal data, from age 2.5 to 5 years, on 126 U.S.-born children with early exposure to Spanish and English. Multilevel models of Spanish and English expressive vocabulary identified children's phonological memory ability as a…

Purpose: The purpose of this study was to evaluate the relation between lexical knowledge and phonological awareness performance of children with cochlear implants. Method: Thirty children with cochlear implants (aged 5-7 years), 30 children with normal hearing matched for age, and 30 children with normal hearing matched for vocabulary size…

The goal of this study was to explore links among shyness, receptive vocabulary, and indices of socioemotional functioning in a sample of young children in mainland urban China. In particular, we sought to examine the potential moderating role of receptive language in these relations. Participants were N = 360 young children (200 boys, 160 girls,…

This study assessed the status of te reo Maori, the indigenous language of New Zealand, in the context of New Zealand English. From a broadly representative sample of 6327 two-year-olds ("Growing Up in New Zealand"), 6090 mothers (96%) reported their children understood English, and 763 mothers (12%) reported their children understood…

The current study evaluated bidirectional associations between mother and father positive parenting and child effortful control. Data were drawn from 220 families when children were 3, 4, 5, and 6 years old. Parenting and effortful control were assessed when the child was 3, 4, and 5 years old. These variables were used to statistically predict…

Early language development predicts later reading competence, but does reading to young children enhance the language interaction between them and their parents? Automatic assessment of language interaction now yields adult word counts, conversational turn counts and child vocalization counts. This study had 98 families return reading activity…

Although many studies have investigated links between maternal employment and children's wellbeing, less research has considered whether the stability of maternal employment is linked with child outcomes. Using unique employment calendar data from the Fragile Families and Child Wellbeing Study (N=2,011), an urban birth cohort study of largely…

The expressive lexical skills of 53 Polish bilinguals aged 24-36 months living in the UK and Ireland were assessed using Polish and British English adaptations of the MacArthur-Bates Communicative Development Inventories. Polish vocabulary scores were compared to those of 53 Polish monolinguals matched for age, gender and parental education. The…
