I am Emeritus Professor of Psychology at the University of Dundee, and a writer, science journalist, public speaker, and comedian. I was formerly Chair of Cognitive Psychology at Dundee, where I was Head of Department and then Dean from 2003 until 2014. I am now a full-time writer and speaker. I am author of several books, including the best-selling text The Psychology of Language, currently in its fourth edition. My research interests are wide, including language, consciousness, sleep and dreams, ageing, futurology, and psychology and the weather. I have suffered all my life from severe anxiety and depression, another subject of my research, and write, talk, and blog about it.
