This $263,750 project grant from the National Institute on Deafness and Other Communication Disorders (NIDCD) under the Research Related to Deafness and Communication Disorders Program (CFDA 93.173) aims to establish a visual mismatch response paradigm using magnetoencephalography (MEG) to examine the effects of early language experience on pre-attentive perceptual processing of American Sign Language (ASL) in deaf and hearing signers. The key products and services to be delivered include: Developing a visual mismatch response paradigm to assess pre-attentive neural sensitivity to changes between real ASL signs and fake signs in hearing signers and non-signers, using MEG combined with MRI scans. Evaluating the impact of early language experience on the visual mismatch response by testing deaf individuals with varying ASL exposure timelines - native signers, early signers, and severely delayed signers. The project aims to further understanding of language development in relation to early language environment and perceptual learning, which can inform guidance for parents and practitioners on early language interventions for deaf children.
