Level 3 Cognition

Level 4 The psychology of everyday life


I obtained my undergraduate degree from the University of Cambridge, where I also carried out the research for my PhD on speech errors. I moved to Dundee in 1996 from the University of Warwick. I work primarily on the psychology and neuropsychology of speech production, and the representation of word meaning. I focus in particular on lexicalisation, the processes whereby we turn thoughts into sounds. I am also interested in the degradation of semantic memory in dementia, and how it might be computationally modelled. I have recently begun a programme of research into language impairments in people with Parkinson's disease, and this has led to an interest in control processes in language. Information about the fourth edition of my textbook can be found on the following doi: The Psychology of Language: From Data to Theory. For further information please see the personal website of Trevor Harley
