Stephen von Tetzchner is professor emeritus of developmental psychology and school psychology at the Department of Psychology, University of Oslo, Norway. His research includes a wide range of issues related to typical and atypical development in general, and communication and language development in particular. He has worked particularly with children who fail to acquire spoken language in the normal manner and may need alternative means of language to augment or substitute speech, including leading the large international project Becoming an Aided Communcator (BAC). He addresses AAC from a developmental perspective, with a focus on the transactional processes that govern language development. He has published textbooks on typical and atypical developmental psychology, language development, augmentative and alternative communication, rehabilitation, challenging behaviour, school psychology, Batten disease and autism spectrum disorder.
