Words influence cognition well before infants know their meanings. For example, three-month-olds are more likely to form visually based categories when exemplars are paired with spoken words than with sine-wave tones, a likely precursor to learning symbolic relations between words and their referents. However, it is unclear why words have these…

Anticipating the learning consequences of actions is crucial to plan efficient information seeking. Such a capacity is needed for learners to determine which actions are most likely to result in learning. Here, we tested the early ontogeny of the human capacity to anticipate the amount of learning gained from seeing. In study 1, we tested infants'…

Using the Infant Behavior Questionnaire--Revised in a longitudinal sample of infant siblings of autistic children (HR; n = 427, 171 female, 83.4% White) and a comparison group of low-risk controls (LR, n = 200, 86 female, 81.5% White), collected between 2007 and 2017, this study identified an invariant factor structure of temperament traits across…

Inhibitory control (IC) is a core executive function integral to self-regulation and cognitive control, yet is itself multi-componential. Directed global inhibition entails stopping an action on demand. Competitive inhibition is engaged when an alternative response must also be produced. Related, but not an executive function, is…

Research Findings: Social constructivist theories have proposed that caregivers' perceptions of children as morally responsible agents are an important factor in children's moral development. However, there is substantial variance in caregivers' ascriptions of moral agency to young children. The present study examined caregiver social conformity…

Purpose: Down Syndrome Regression Disorder (DSRD) is a diagnosis of exclusion. Psychiatric and neuroimmunologic etiologies have been proposed although the exact etiology remains unknown. This study sought to review non-DSRD diagnoses at a large quaternary medical center specializing in the diagnosis of DSRD and compare clinical characteristics…

The MacArthur-Bates Communicative Development Inventories (CDI) are widely used, parent-report instruments of language acquisition. Here, we focus on the word-inventory sections of the instruments, and show two different approaches to modeling CDI data, based on real-world needs. First, we show that Words & Gestures data collected…

Executive control (EC) emerges in the first year of life, with the ability to inhibit prepotent responses (inhibitory control [IC]) and to flexibly readapt (cognitive flexibility [CF]) steadily improving. Simultaneously, electrophysiological brain activity undergoes profound reconfiguration, which has been linked to individual variability in EC.…

Purpose: The study aimed to compare eye tracking (ET) and manual coding (MC) measures of attention to social and nonsocial information in infants with elevated familial likelihood (EL) of autism spectrum disorder (ASD) and low likelihood of ASD (LL). ET provides a temporally and spatially sensitive tool for measuring gaze allocation. Existing…

The importance of the parent-child relationship during early childhood (i.e., 0-5 years) on children's socioemotional functioning has been extensively documented in the literature. However, limited work has examined the degree to which dyadic features of the parent-child relationship changes over the course of early childhood and whether growth in…

For many children, their home is where they first encounter digital media technologies. The aim of this study is to investigate how children 0 - 3 years old engage in digital media. We address digital literacies as a sociocultural mindset and a toolbox with attention to skills and comprehensions as well as how children express their agency. The…

The present study assessed both concurrent and early influences of the maternal caregiving environment to examine unique contributions of each to variation in children's emotional responses to COVID-19 pandemic. Preschoolers (3-5 years; M = 4.12, SD = 0.49) previously assessed in infancy, several years prior to pandemic outbreak, were re-assessed…

Purpose: This study evaluates the impact of temporal synchrony between maternal touch and speech on children's early language development. It investigates whether the proportion of word-touch co-occurrence, overlap, and alignment precision in maternal input influences language acquisition, hypothesizing that such synchrony boosts infants'…

New Zealand participation rates for under-3-year-olds in ECE services continue to show the biggest growth rates across the 0-5-year-old age range. Yet policy provisions to safeguard high-quality experiences in their early years settings continue to lag behind research-based indicators of high-quality provision for this age group. This article…

A growing body of research suggests that infant and early childhood mental health consultation (IECMHC) is effective in improving child outcomes and classroom quality in early care and education (ECE) settings. However, there is limited research regarding the provision of IECMHC virtually (e.g., by phone or video conferencing platform), and the…
