Sophie Scott is a Wellcome Trust Senior Fellow and Professor of Cognitive Neuroscience at University College London. She has drawn together theories and techniques from speech sciences, psychology and primate neuroanatomy in order to understand how the human brain processes speech. Her work was the first to identify that the early perceptual processing of speech parallels the perception of conspecific calls in non-human primate brains. This has contributed to our understanding of recovery from aphasic stroke. She has applied this work to hearing loss, with particular reference to how people can adapt to cochlear implantation. She is now extending her work to understanding the social aspects of communication.
