Objective: The tendency to vocalize toward objects is ubiquitous among young infants. However, little is known about the range of this tendency and its contribution to language development. Therefore, this longitudinal study objective was to explore the role of three forms of vocal behavior (vocalization, babbling, and speech) directed toward…

Purpose: Measuring the growth of young children's vocabulary is important for researchers seeking to understand language learning as well as for clinicians aiming to identify early deficits. The MacArthur-Bates Communicative Development Inventories (CDIs) are parent report instruments that offer a reliable and valid method for measuring early…

Single case research designs (SCRDs) are integral to identifying evidence-based practices (EBPs) for young children with autism spectrum disorder (ASD); however, the field lacks guidance on measuring response maintenance within SCRDs. We identified 103 studies in which researchers used SCRD to investigate the maintenance of behavioral intervention…

There is a lack of feasible and psychometrically sound instruments assessing social-emotional development in young children in low- and middle-income countries. The objective of this cross-sectional study was to investigate the psychometric properties of the Brief Infant-Toddler Social and Emotional Assessment (BITSEA) in two West-African…

A rich literature describes the efficacy of coaching programs for early care and education (ECE) teachers. ECE teachers can provide unique insights into the coaching process and several studies have described the coaching experience from the perspective of ECE teachers serving preschool-age children. However, limited data are available to describe…

This article examines how 1043 toddlers (534 boys and 509 girls) aged 33 months cope with various play activities, from a gender perspective. Data were collected through structured observation using the authentic assessment material "Alle Med" (Everyone Included). Each child was assessed independently by two staff members familiar with…

The International Classification of Functioning, Disability and Health (ICF) offers a universal language of codes to document childhood functioning. The ICF-CY Code Set for Infants with Early Delay and Disabilities (EDD Code Set) has been developed to facilitate the practical application of the ICF for children. The purpose of this study was to…

Background: As delays or disorders in early language and communication are the most prevalent symptom in children with disabilities, early screening is crucial to promote prevention, early diagnosis, and intervention. However, to the best of our knowledge, no screening tool is available for the joint assessment of early language and social…

The Mayan language Mam uses complex predicates to express events. Complex predicates map multiple semantic elements onto a single word, and consequently have a blend of lexical and phrasal features. The chameleon-like nature of complex predicates provides a window on children's ability to express phrasal combinations at the one-word stage of…

Emotion regulation (ER) is a source of risk and resilience for psychological development and everyday functioning. Despite extensive research on various early contextual predictors of child ER capacity, few studies have integrated them into the same study. Therefore, our longitudinal study investigated the joint and independent contributions of…

Upon hearing a novel label, listeners tend to assume that it refers to a novel, rather than a familiar object. While this disambiguation or mutual exclusivity (ME) effect has been robustly shown across development, it is unclear what it involves. Do listeners use their pragmatic and lexical knowledge to exclude the familiar object and thus select…

The prevalence of autism spectrum disorder (ASD) has risen significantly in the past two decades. Unfortunately, there is a shortage of mental health providers who have specialized training in delivering evidenced-based services to this population. Early intensive behavioral intervention (EIBI) is an evidenced-based treatment recommended for…

This study aimed to explore whether early developmental abilities are related to future executive function (EF) in children with motor delays. Fourteen children with motor delays (Mean age = 10.76, SD = 2.55) were included from a larger study. Object interaction and developmental outcomes (Bayley-III) were evaluated at baseline and 3, 6, and 12…

This brief presents select findings from the "Conversion of Enrollment Slots from Head Start to Early Head Start (HS2EHS) Case Studies," six case studies of grant recipients that converted enrollment slots from Head Start to Early Head Start in 2021. This brief focuses on "implementing new or expanded Early Head Start services…

A growing number of toddlers are attending childcare institutions as part of China's establishment of its infant-toddler childcare service system. However, there is limited empirical evidence available regarding the quality of these childcare services. The purpose of this study is to investigate the quality of teacher - child interactions in…
