Socioeconomic disparities in early language are widespread and have long-lasting effects. The aim of this study is to investigate when social gaps in language problems arise and how they change across the first years of schooling. We address this question in two large longitudinal Norwegian datasets: the Behavior Outlook Norwegian Developmental…

This mixed two-way experimental, cross-sectional study investigated fast-mapping (FM) of novel nouns and verbs in 63 Persian-speaking toddlers aged 30 months, including 31 late-talking (LT) and 32 typically developing (TD) matched with respect to age and maternal education. Toddlers were classified as LT if they had limited expressive vocabulary…

Previous literature has shown that family structure affects language development. Here, factors relating to older siblings (their presence in the house, sex, and age gap), mothers (maternal stress), and household size and residential crowding were assessed to systematically examine the different roles of these factors. Data from mother-child dyads…

Background and Purpose: Schoolchildren with language difficulties experience more peer victimization compared to their typically developing (TD) peers. Whether these children also bully their peers (bully perpetration) more than TD children is unclear. Furthermore, little is known about peer victimization and bully perpetration among preschool…

We aimed to evaluate the validity of the Ages and Stages Questionnaires Edition 3 (ASQ-3) and the MacArthur communicative development inventory (CDI) as a screening measure for children at risk of language development delay in western rural China, by comparing them to the Bayley Scales of Infant and Toddler Development (BSID-III). We administered…

Spanish-English-speaking dual language learners (SE-DLLs) from low-income backgrounds are at risk for experiencing academic difficulty compared to peers of ethnic-majority, middle- and high-income backgrounds. Caregiver language input is a consistent predictor of later developmental and academic outcomes. The current study targeted caregivers (n…

Early childhood is a critical period characterized by rapid development of motor and language skills. Reliably assessing motor and language development in early childhood is difficult, and there is a lack of agreement on measurement tool use. This scoping review aims to identify measurement tools used to examine motor and language skills in…

The Sustainable Development Goals mandate that by 2030, all children should have access to quality early child development opportunities, healthcare and pre-primary education. Yet validated measures of ECD in low and middle income countries (LMICs) are rare. To address this gap, a Systematic Review (SR) of measures available to profile the…

This list of tools was compiled to assist states and programs with identifying assessments that can be administered when the assessor cannot be in the room with the child. This is a list of screening tools that can be completed remotely when the practitioner cannot be in the room with the child. Screening tools assess the possibility of a…
