Rachel I. Mayberry is a professor of linguistics at the University of California San Diego where she directs the Laboratory for Multi-Modal Language Development. Professor Mayberry studies the development and psycholinguistic and neurolinguistic processing of language structure in the visual modality. Her main research uses American Sign Language and deafness to investigate the linguistic and neural correlates of childhood language deprivation. She has also pioneered research on the relation between sign language acquisition and reading development, the development of iconic gestures in bilingual children's two spoken languages, and the effects of speech dysfluency on gesture expression. Her research has been contiguously funded by Canadian and American granting agencies and she was recently given the Distinguished Alumni Research Leadership Award from the McGill University School of Communication Sciences and Disorders.
