The power and precision with which humans link language to cognition is unique to our species. By 3-4 months of age, infants have already established this link: simply listening to human language facilitates infants' success in fundamental cognitive processes. Initially, this link to cognition is also engaged by a broader set of acoustic stimuli,…

Purpose: This study aims to examine the development of auditory selective attention to speech in noise by examining the ability of infants to prefer child-directed speech (CDS) over time-reversed speech (TRS) presented in "on-channel" and "off-channel" noise. Method: A total of 32 infants participated in the study. Sixteen…

Object names are a major component of early vocabularies and learning object names depends on being able to visually recognize objects in the world. However, the fundamental visual challenge of the moment-to-moment variations in object appearances that learners must resolve has received little attention in word learning research. Here we provide…

Early temperament predicts various aspects of development. In large-scale studies, temperament is often assessed via parental report because naturalistic and structured observations are costly and bear the risk of subject loss. However, the validity of such parental reports has been disputed repeatedly. This article compared parental reports on…

Presenting pictures of faces side by side is a common paradigm to assess infants' attentional biases according to social categories, such as gender, race, and language. However, seeing static faces does not represent infants' typical experience of the social world, which involves people in motion and performing actions. Here, we assessed infants'…

A semistructured preschool motor program was developed in response to the paucity of evidence-based motor programs for preschoolers with disabilities in inclusive classrooms. A randomized controlled trial (RCT) was undertaken to examine the impact of the "CHildren in Action: Motor Program for PreschoolerS (CHAMPPS)," a 21-week…

This study investigated the development of rapid visual object categorization. N = 20 adults (Experiment 1), N = 21 five to six-year-old children (Experiment 2), and N = 140 four-, seven-, and eleven-month-old infants (Experiment 3; all predominantly White, 81 females, data collected in 2013-2020) participated in a fast periodic visual stimulation…

Toddlers with smaller vocabulary than expected for their age are considered late talkers (LT). This study explored the effects of characteristics of words on vocabulary acquisition of 12- to 24-month-old LT children compared with an age matched (AM) and a vocabulary matched (VM) group of typically developing peers. Using the…

Researchers and practitioners need robust measurement tools for evaluating knowledge of child development to better support parents and their children during pregnancy and the transition to parenthood. We addressed this need by evaluating the psychometric properties of the Domains of Development Instrument (DoDI) for measuring knowledge of…

Using a drawing-based research approach, this qualitative study explored in-service infant teachers' reflections on their play experiences and ways of supporting and scaffolding infants' play at a childcare center in Korea. The participants engaged in a drawing task that illustrated their reflections and memories of their play. They then discussed…

Child observation is a critical component of quality pedagogy in early childhood education and care (ECEC). The ORICL (Observe, Reflect, Improve Children's Learning) tool was co-designed by ECEC researchers, policymakers, leaders, and practitioners to support this work. Educators rate the experiences of individual children, and responses of…

CDKL5 deficiency disorder (CDD) results in early-onset epilepsy and lifelong cognitive and motor impairments. With no validated measure for communication in CDD, this study evaluated the psychometric properties of the Communication and Symbolic Behavior Scales-Developmental Profile Infant Toddler Checklist (CSBS-DP ITC). Caregivers (n = 150;…

Background: Drawing on the family stress model (Conger and Donnellan in Ann Rev Psychol 58:175-199, 2007. https://doi.org/10.1146/annurev.psych.58.110405.085551), parenting programs typically support caregivers' nurturing and cognitively stimulating practices to mitigate the effects of poverty on child development, with small-to-moderate…

Home-visitation programs have improved child development in low- and middle-income countries, but they are costly to scale due to their reliance on trained workers. We evaluated an inexpensive and low-tech alternative with 2,433 caregivers of children aged 6 to 30 months served by 250 public childcare centers in Uttarakhand, India: automated phone…

Early intervention (EI) home visitation programs are central to delivering services that support infants and toddlers displaying developmental delays or disabilities and their families. Entities that oversee such programs continually seek to strengthen the quality of program practices. The "Getting Ready" approach is a professional…
