Early auditory experience depends not only on access to auditory input, but also the nature of that input. In a current NIDCD-funded project, we are recording real-world input in the home to infants and toddlers who use hearing aids and/or cochlear implants using the Language ENvironment Analysis (LENA) system. We are analyzing the recordings to determine the quantity of spoken language input directed to children and qualities of that input, such as intonational properties and characteristics of the vocabulary used. We investigate how these quantitative and qualitative properties influence language outcomes, especially children’s ability to learn novel words. 

This study investigates the dynamics of parent-child interactions to determine how coordination of interactions affects object name learning. For example, do children learn object names better when the parent holds an object and directs the child’s attention to it or if the parent waits to name the object when the child attends to the object on his/her own? How does auditory experience influences the effects of these interactions? These questions are addressed using head-mounted cameras, eye trackers, audio recordings, and object recognition technology (see Figure) to produce information-rich data collected during parent-child free-play sessions. Sophisticated algorithms allow us to mine the data for patterns connecting interactions to learning.

Other projects include assessment of infants’ speech perception skills after cochlear implantation and investigating the effects of auditory experience on the development of nonverbal/nonauditory cognitive skills. I am also involved in collaborations to address barriers to access to high-quality early hearing detection and interaction and community based participatory action research.
