This study investigates the development of canonical proportion (CP), an indicator of vocal maturity, across diverse language and environmental contexts. Using the Speech Maturity Dataset (SMD) comprising 369 children, aged 0;2-6;4, across ten different...
Individual differences in early language input are rampant but hard to quantify without resource-intensive naturalistic recordings, posing a challenge for testing links between individual experience and facets of language development like vocabulary...

We investigated how experience with particular nouns and referents influences infant word comprehension by combining home recordings with in-lab eyetracking. In Study 1, infants (n=44) participated in a yearlong longitudinal study which included monthly...
Purpose:
To compare spoken language input to young deaf/hard of hearing (DHH) children with cochlear implants and matched chronological- and hearing-age hearing controls.
Method:
We used long-form audio-recordings (M=14.3hrs) from 48 6-32mo’s (16/group). We...
Blind infants cannot acquire information about the world using vision, which may make it more difficult to connect words they hear to referents that, for sighted infants, are readily visually available. We ask whether, in light of this, caregivers talk...
The study of infant cognitive and language development has been limited by small samples and the need for in-person visits. The Remote Infant Studies of Early Learning (RISE) was designed to assess early development on a larger scale. The battery includes...

We investigate how children form early grammatical generalizations using the test case of the English regular plural. While some previous studies demonstrate that children apply abstract grammatical rules to produce novel plurals before 24 months, other...

We investigate the roles of linguistic and sensory experience in the early-produced visual, auditory, and abstract words of congenitally-blind toddlers, deaf toddlers, and typically sighted/hearing peers. We also assess the role of language access by...
We compared everyday language input to young congenitally-blind children with no additional disabilities (N=15, 6–30 mo., M:16 mo.) and demographically-matched sighted peers (N=15, 6–31 mo., M:16 mo.). By studying whether the language input of blind...

Prior work finds that some elements of language input or skills during infancy and toddlerhood predict later language skills. Here, we ask if combining these two sources of information about early language development improves predictions of language...
We introduce HARMONI, a three-dimensional (3D) computer vision and audio processing method for analyzing caregiver-child behavior and interaction from observational videos. HARMONI operates at subsecond resolution, estimating 3D mesh representations and...
Background
Our aim was to update an existing model of communication ability for children with rare
neurodevelopmental disorders (NDDs) by centering caregiver and family perspectives. This project is part of a larger initiative to improve the measurement of...
