Within a language, there is considerable variation in the pronunciations of words owing to social factors like age, gender, nationality, and race. In the present study, we investigate whether toddlers link social and linguistic variation during word learning. In Experiment 1, 24- to 26-month-old toddlers were exposed to two talkers whose front…

Developing early reading skills is important for long-term academic success. Too often, however, young children do not have the foundations of literacy they need. One-third of Tennessee students read on grade level (Tennessee Department of Education, 2021), and in the state's capital city of Nashville, three out of four 3rd graders are not reading…

This study examines the extent to which iron deficiency in infancy contributes to adverse neurocognitive and educational outcomes in young adulthood directly and indirectly, through its influence on verbal cognition and attention problems in childhood. Young adults (N = 1,000, M age = 21.3 years, 52% female; of Spanish or indigenous descent) from…

This article critically interrogates the model of language that underpins early years policy and pedagogy. Our arguments emerge from an ethnographic study involving 2-year-olds attending a day care centre that had begun to hold a substantial proportion of its sessions outdoors. The resultant shift in pedagogy coincided with changes in the…

Health disparities in ASD detection affect children's access to subsequent interventions. We examined potential disparities in implementation of a multi-stage ASD screening and diagnostic evaluation protocol in Part C Early Intervention with 4943 children ages 14-36 months (mean 22.0 months; 62.9% boys, 73.3% children of color, 34.9%…

Purpose: Few caregiver-implemented naturalistic language interventions (NLIs) are available for Spanish-speaking Latinos who have young children under 3 years with language delays, and there is a scarcity of studies that provide information about intervention development or social validity of interventions for this group. This study introduces…

This article examined the associations between family processes and children's development among mothers and their children participating in early intervention (EI) services. Data from mothers and their infants and toddlers (n = 100) participating in EI were analyzed using regression methods to test the predictive power of maternal depressive…

Purpose: Few caregiver-implemented naturalistic language interventions (NLIs) are available for Spanish-speaking Latinos who have young children under 3 years with language delays, and there is a scarcity of studies that provide information about intervention development or social validity of interventions for this group. This study introduces…

Purpose: This study reexamines the claim that difficulty forming memories of words comprising uncommon sound sequences (i.e., low phonological neighborhood density words) is a determinant of delayed expressive vocabulary development (e.g., Stokes, 2014). Method: We modeled communicative development inventory data from (N = 442) 18-month-old…

This paper draws on a research study that builds on a long and rich history of research in environmental education focusing on the value of learning through everyday experiences with the more than human. This study specially focused on very young children's experiences of ecologies and explored the unique opportunities sensorially rich bodily…

Differential diagnosis of autism spectrum disorder (ASD) is challenging, and uncertainty regarding a child's diagnosis may result in under-identification or prolonged diagnostic pathways. The current study examined diagnostic certainty, or how sure clinicians were that their diagnosis was accurate, among 478 toddler and preschool-aged children…

Autism Spectrum Disorder (ASD) diagnostic tools are not designed for mental ages (MA) below 12 months. Autism Diagnostic Observation Schedule (ADOS) and Childhood Autism Rating Scale (CARS) were examined in 2-year-olds with ASD-low MA (n = 53), Global Developmental Delay (GDD; n = 175), and ASD-higher MA (n = 425). ADOS and CARS demonstrated…

Word learning depends critically on the use of linguistic context to constrain the likely meanings of words. However, the mechanisms by which children infer word meaning from linguistic context are still poorly understood. In this study, we asked whether adults (n = 58) and 2- to 6-year-old children (n = 180) use discourse coherence relations…

The Department Children, Youth, and Families (DCYF) is a new cabinet level agency focused on the well-being of children. The vision is to ensure that "Washington state's children and youth grow up safe and healthy-thriving physically, emotionally and academically, nurtured by family and community." (House Bill 1661) DCYF serves as the…

This study aims to investigate the language-learning environment and educational language practices in four toddler groups measured as high quality on the 'Listening and Talking' subscale in the Infant/Toddler Environment Rating Scale -- Revised. The empirical data are taken from a larger fieldwork conducted in four child groups, and comprise 98…
