Research focus
My research investigates how limited access to sound affects the development of children with hearing loss. To do this, we examine the consistency of auditory-linguistic input for children who are deaf or hard of hearing. We theorize that individual differences in linguistic representations and processing are the result of variations in exposure to spoken language. Thus, inconsistent auditory access may result in inefficient processing and poorer outcomes in children with hearing loss. Our lab uses diverse measures to assess children’s abilities, including standardized tests of language and cognition, dynamic learning tasks, clinical audiologic measures, questionnaires, and dual-task paradigms. The long-term goal of our research is to inform and improve the evidence-based care that audiologists and speech-language pathologists provide to children with hearing loss.
