Speech Motor Control

Ben Maassen (Professor of Neurolinguistics - Dyslexia) has a background in cognitive neuropsychology and speech-language pathology. He is project coordinator in the Dutch Dyslexia Programme, leader of projects on speech motor control and developmental neuropsychological disorders, and teacher in the master-programme Speech-Language Pathology and research-master programmes Clinical Linguistics (Erasmus Mundus) and Cognitive Neuroscience. Main research areas are neurogenic speech disorders, perception-production modelling, dyslexia and neurocognitive precursors of literacy. As a Clinical Neuropsychologist he is coordinator of an expertise centre for children with speech and language disorders. Pascal van Lieshout is an Associate Professor in the Department of Speech-Language Pathology at the University of Toronto, a Canada Research (II) in Oral Motor Function, and director of the Oral Dynamics Lab. His interest is in oral motor control in speech and swallowing with a focus on applying Dynamical Systems Theory in these areas of research. He has published over 100 peer-reviewed papers in international journals, books and conference proceedings and is renowned for his studies of articulation in speech motor disorders, in particular stuttering.
