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...
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...
In many circumstances, age and experience with language go hand in hand, making it challenging to disentangle their roles in early word learning. Here we use shared book-reading as a vehicle for structured but naturalistic language exposure, allowing us...
Children exhibit substantial vocal development in their first years of life, laying the foundation for later language. This paper asks how key aspects of their linguistic experience relates to one aspect of this development. We focus on three factors that...

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...
This study investigates the development of canonical proportion (CP), an indicator of speech development, across diverse language and environmental contexts. Using the Speech Maturity Dataset (SMD) comprising 366 children, aged 0;2–6;4, across 10...
Object-centric interactions provide rich sources of multimodal input for early learning. Using daylong photo streams from child-worn cameras, we analyze > 90k images to identify the frequency and targets of object handling across the first three years of...
Our original paper found effects of linguistic experience on music perception which generalized across a half-million speakers of fifty-four languages. In a critique, Creel claims that our multilevel modelling approach biased the language-level estimates...

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...
