Pronunciation variation is under-studied in infant-directed speech, particularly for consonants. Regressive place assimilation involves a word-final alveolar stop taking the place of articulation of a following word-initial consonant. We investigated pronunciation variation in word-final alveolar stop consonants in storybooks read by forty-eight…

Measures of young children's social development are needed in the Multi-Tier System of Supports (MTSS) approach to early childhood. In 2004, we reported initial development of an observational measure of infants' and toddlers' social skills designed for early educators, the Early Social Indicator (ESI). Here, we report preliminary findings on the…

In the United States, there is a widespread concern with not referring more infants and toddlers with a risk of or identified autism spectrum disorder (ASD) to Early Intervention (EI) under Part C of the Individuals with Disabilities Education Act (IDEA, 2004). Despite early signs and screening initiatives, most children with ASD are not referred…

Spontaneous verbal repetition is part of early adult-child conversational interchanges. However, most of the studies devoted to verbal repetition analyse child-produced and adult-produced repetition independently. The aim of this study is to analyse verbal repetition sequences that are extended by children and adults participating in turns. We…

Infant/Early Childhood Mental Health Consultation (IECMHC) is a relationship-based, collaborative support designed to improve the capacity of early childhood professionals to promote children's mental health. Social and emotional development is the foundation for success in learning and in life. It begins in children's early relationships with…

In 2004, we reported initial development of an observational measure of infants' and toddlers' social skills designed for early educators, the Early Social Indicator (ESI).

In this article, the authors examine the mathematical thinking and experiences that are unique to infants, toddlers, and 2-year-olds. They identify the four precursor mathematical concepts of attribute, comparison, pattern, and change and explore them in terms of why it is so important to attend to them, what makes them inherently mathematical and…

In order to understand how language abilities emerge in typically and atypically developing infants and toddlers, it is important to embrace complexity in development. In this paper, we describe evidence that early language development is an experience-dependent process, shaped by diverse, interconnected, interdependent developmental mechanisms,…

The study was designed to investigate pragmatic development and the ability to make comments/questions on social and non-social topics in Italian-speaking children aged 18-47 months. Parents of 190 children completed an adaptation of the Language Use Inventory into Italian. Overall, the children's performance on the subscales of the LUI-Italian…

Language experience shapes infants' abilities to process speech sounds, with universal phonetic discrimination abilities narrowing in the second half of the first year. Brain measures reveal a corresponding change in neural discrimination as the infant brain becomes selectively sensitive to its native language(s). Whether and how bilingual…

This article defines the concept of Infant and Early Childhood Mental Health (IECMH) and describes how it provides the foundation for lifelong health and well-being. The authors provide policy recommendations that include the need to: (a) establish cross-agency leadership for IECMH, (b) ensure Medicaid payment for IECMH services, (c) invest in…

There is a critical need for evidence-based, broadband behavioral, and ASD screening measures for use in pediatric and early educational settings to ensure that young children at risk for developing social-emotional disorders and/or ASD are provided with early intervention services to optimize long-term outcomes. The BITSEA is a 42-item screener…

Recently it has been proposed that sensitivity to nonarbitrary relationships between speech sounds and objects potentially bootstraps lexical acquisition. However, it is currently unclear whether preverbal infants (e.g., before 6 months of age) with different linguistic profiles are sensitive to such nonarbitrary relationships. Here, the authors…

This brief report provides facts about Early Support for Infants and Toddlers (ESIT) on the following topics: (1) What is the purpose of the IDEA Part C early intervention?; (2) Early intervention service delivery in Washington, July 1, 2015 through June 30, 2016; (3) Primary early intervention services; (4) What are the expected child outcomes?;…

The development of visual attention is a key component of cognitive functioning in infancy and childhood. By the time children in poverty reach school, deficits in attention are readily apparent; however, when these attention delays manifest is unknown. The current study tested attention longitudinally at 6, 9 and 12?months in infants from…
