This study examined long-term mediating effects of the "smalltalk" parenting intervention on children's effortful control at school age (7.5 years; 2016-2018). In 2010-2012, parents (96% female) of toddlers (N = 1201; aged 12-36 months; 52% female) were randomly assigned to either: standard playgroup, "smalltalk" playgroup…

This National Early Head Start Services Snapshot summarizes key data on demographics and services for infants, toddlers, and pregnant women served by Early Head Start programs. The data in this Snapshot is a subset of the annual Program Information Report (PIR) submission to the Office of Head Start. Data categories include: (1) Funded Enrollment;…

This National Head Start Services Snapshot summarizes key data on demographics and services for preschool-age children served by Head Start programs. The data in this Snapshot is a subset of the annual Program Information Report (PIR) submission to the Office of Head Start. Data categories include: (1) Funded Enrollment; (2) Funded Enrollment by…

This National Services Snapshot summarizes key data on demographics and services for children from birth to age five and pregnant women served by Head Start, Early Head Start, and Migrant and Seasonal Head Start programs. The data in this Snapshot is a subset of the annual Program Information Report (PIR) submission to the Office of Head Start.…

This Migrant and Seasonal Head Start (MSHS) Services Snapshot summarizes key data on demographics and services for children from birth to age five and pregnant women served by all Migrant and Seasonal Head Start programs. The data in this Snapshot is a subset of the annual Program Information Report (PIR) submission to the Office of Head Start.…

This study investigates whether the earliest words children choose to say are mainly words containing sounds they can produce (cf. 'phonological dominance' hypotheses), or whether children choose words without regard to their phonological characteristics (cf. 'lexical dominance' hypotheses). Phonological properties of words in spontaneous speech…

Children's language and cognitive development are informed by adult spoken language and parental literacy behaviors, although their relative contributions have not been evaluated. Using digital audio-recorders, we unobtrusively observed the spoken language of 107 children, aged 24 to 48 months (M = 32, SD = 6.5), and their families over 3 days (M…

This study aims to disentangle the often-confounded effects of input frequency and morphophonological complexity in the acquisition of inflection, by focusing on simple and complex verb forms in Japanese. Study 1 tested 28 children aged 3;3-4;3 on stative (complex) and simple past forms, and Study 2 tested 30 children aged 3;5-5;3 on completive…

This paper provides an overview of the features of caregiver input that facilitate language learning across early childhood. We discuss three dimensions of input quality: interactive, linguistic, and conceptual. All three types of input features have been shown to predict children's language learning, though perhaps through somewhat different…

Data from children with ASD who are learning Indo-European languages indicate that (a) they vary hugely in their expressive language skills and (b) their pragmatic/socially-based language is more impaired than their structural language. We investigate whether similar patterns of language development exist for Mandarin-exposed children with ASD.…

Accuracy of autism screening using M-CHAT plus the follow-up interview (M-CHAT/F) for children screened positive at 18-months was compared to screening at 24-months. Formal ASD testing was criterion for a community sample of M-CHAT positive children (n = 98), positive predictive value (PPV) was 0.40 for the M-CHAT and 0.58 for the M-CHAT/F.…

Four early childhood educators, along with a university researcher, describe their efforts to implement an antiracist, antibias curriculum in a daycare and preschool setting. Even very young children can learn important lessons about race, diversity, and equity, they argue, and teachers should not shy away from addressing these issues at staff…

The early home language environment, and parents in particular, form the foundation of children's language development. In this article, Dina Kapengut and Kimberly Noble explore the intersection of neuroscience and developmental psychology to explain how language experiences in the home, and the "home learning environment" more broadly,…

The goal of the current study was to statistically evaluate the reliable scalability of a set of tasks designed to assess Theory of Mind (ToM) without language as a confounding variable. This tool might be useful to study ToM in populations where language is impaired or to study links between language and ToM. Low verbal versions of the ToM tasks…

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…
