Karalyn Eve Patterson, FRS, FBA, FMedSci (born 28 October 1943) is a British psychologist in Department of Clinical Neurosciences, University of Cambridge and MRC Cognition and Brain Sciences Unit, Cambridge. She is a specialist in cognitive neuropsychology.
Karalyn Patterson was one of the prime initiators of the field of cognitive neuropsychology. The different approaches she has developed to study brain based disorders of language and memory have brought great rigour to the field, and have allowed stringent tests of different theories. She is one of the very few people in the world able to adopt a truly multi-disciplinary approach including computational modelling, behavioural observation, neuropsychological testing and functional neuroimaging. Consequently, her work has led to a better understanding of how language and memory are organised in the brain, and how they unravel in Alzheimer's disease and other types of dementia.
