Testing the relationship between preferences for infant-directed speech and vocabulary development: A multi-lab study
From early on, infants show a preference for infant-directed speech (IDS) over adult-directed speech (ADS), and exposure to IDS has been correlated with language outcome measures such as vocabulary. The present multi-laboratory study explores this issue by investigating whether there is a link between early preference for IDS and later vocabulary size. Infants’ preference for IDS was tested as part of the ManyBabies 1 project, and follow-up CDI d…
Validation of an open source, remote web‐based eye‐tracking method (WebGazer) for research in early childhood
Measuring eye movements remotely via the participant's webcam promises to be an attractive methodological addition to in‐person eye‐tracking in the lab. However, there is a lack of systematic research comparing remote web‐based eye‐tracking with in‐lab eye‐tracking in young children. We report a multi‐lab study that compared these two measures in an anticipatory looking task with toddlers using WebGazer.js and jsPsych. Results of our remotely tes…
A changing role for transitional probabilities in word learning during the transition to toddlerhood
Infants' sensitivity to transitional probabilities (TPs) supports language development by facilitating mapping high-TP (HTP) words to meaning, at least up to 18 months of age. Here we tested whether this HTP advantage holds as lexical development progresses, and infants become better at forming word-referent mappings. Two groups of 24-month-olds ( N = 64 and all White, tested in the United States) first listened to Italian sentences containing HT…
Covid-19 first lockdown as a window into language acquisition: Associations between caregiver-child activities and vocabulary gains
The COVID-19 pandemic, and the resulting closure of daycare centers worldwide, led to unprecedented changes in children’s learning environments. This period of increased time at home with caregivers, with limited access to external sources (e.g., daycares) provides a unique opportunity to examine the associations between the caregiver-child activities and children’s language development. The vocabularies of 1742 children aged 8-36 months across 1…
Quantifying Sources of Variability in Infancy Research Using the Infant-Directed-Speech Preference
Psychological scientists have become increasingly concerned with issues related to methodology and replicability, and infancy researchers in particular face specific challenges related to replicability: For example, high-powered studies are difficult to conduct, testing conditions vary across labs, and different labs have access to different infant populations. Addressing these concerns, we report on a large-scale, multisite study aimed at (a) as…
