This week we spoke to Dr Paul Bays, the group leader of the Computational Cognition Group in the Department of Psychology at the University of Cambridge. His research focuses on visual working memory, which is our ability to recall details of what we have just seen. Paul explains how visual working memory is different to other forms of memory, and how his group uses a combination of computational modelling and volunteer trial data to form an understanding about how visual working memory works. We also discuss eidetic or "photographic" memory, and how neurodegenerative diseases such as Alzheimer's disease can impact visual working memory.
