We investigated infant's manual motor behaviour; specifically behaviours crossing the body midline. Infants at elevated likelihood of Autism Spectrum Disorder (ASD) and/or Attention Deficit Hyperactivity Disorder (ADHD) produced fewer manual behaviours that cross the midline compared to infants with a typical likelihood of developing these…

This article draws on a study of infant participation in research, and work in philosophical-empirical inquiry, to illuminate some of the inexhaustible entanglements constituting the "collective" relational landscape of educational research of particular encounters, which have been called "moments of wonder." Working with…

Recent studies indicate that premature children are at risk for difficulties with cognitive development and have increased incidence of ADHD as well as other behavioral disorders. Although the exact mechanism accounting for these children's neuropsychological abnormalities is unknown, there is evidence to suggest that the cognitive and behavioral…

This research examined how 5-, 8-, and 11-month-olds with female primary caregivers mentally represented faces using a familiarization procedure similar to real-world experience in which infants have greater exposure to female faces aged 21-39 years than other face types. We predicted infants would form weighted representations of faces (i.e.,…

Purpose: Language difficulties are prevalent among children born preterm. Existing studies have largely used standardized language tests, providing limited scope for detailed descriptive examination of preterm language. This study aimed to examine differences in conversational language between children born < 30 weeks and at term as well as…

This conceptual article examines how ready-made assumptions about literacy both frame and limit understandings of new communicative practices in educational contexts. Proposing a tripartite heuristic that interrogates the appearance of literacy in terms of emergence, semblance and performance, it uses stories from a study of touchscreen tablets in…

We investigated gestures that parents used with 12-, 18-, and 24-month-old infants at high or low risk for autism spectrum disorder (ASD; high-risk diagnosed with ASD: n = 21; high-risk classified as no ASD: n = 34; low-risk classified as no ASD: n = 34). We also examined infant responses to parent gestures and assessed the extent to which parent…

Purpose: Fathers play a critical but underresearched role in their children's cognitive and linguistic development. Focusing on two-parent families with a mother and a father, the present longitudinal study explores the amount of paternal input infants hear during the first 2 years of life, how this input changes over time, and how it relates to…

It is well established that deictic gestures, especially pointing, play an important role in children's language development. However, recent evidence suggests that other types of deictic gestures, specifically show and give gestures, emerge before pointing and are associated with later pointing. In the present study, we examined the development…

We investigated the continuity and stability of imitative episodes (IMEs) to shed light on the nature of early infant imitative ability. We observed and analyzed interactions of 27 mother-infant pairs as they played in their homes at one and 10 months. We coded the initiator, frequency, duration, kind, structure, and affect of IMEs. At 10 months,…

Assessing children's working memory capacity (WMC) can be challenging for a variety of reasons, including the rapid increase in WMC across early childhood. Here, we developed and piloted an adapted WMC task, which involved minimal equipment, could be performed rapidly, and did not rely on verbal production ability (to facilitate the use of the…

ZERO TO THREE and Los Angeles County Department of Mental Health (LACDMH) collaborated and contracted to provide official DC:0-5[TM] clinical training and foundational infant and early childhood mental health training to clinicians from Los Angeles (LA) County, California, over the course of 3 years. This article describes this unique, multiyear…

The "DC:0-5[TM]: Diagnostic Classification of Mental Health and Developmental Disorders of Infancy and Early Childhood" (DC:0-5) includes significant revisions, making it a substantially different diagnostic framework from its predecessor, DC:0-3R. The Nordic countries have a long history of using the DC system. The Nordic DC:0-5…

Indigenous lifeways, perspectives, and ways of knowing in the field of infant and early childhood mental health are underrepresented, especially given the inequitable and unjust prevalence of removal and separation of American Indian and Alaska Native (AI/AN) children from their families and communities by the child welfare system in the United…

Interventions to enhance cognitive and executive function performance are essential for the child's performance in current and future occupations. Occupational therapy practitioners are critical members of early intervention, education, and healthcare teams. Practitioners are distinctly qualified to address cognitive functioning within the context…
