Trevor Harley

Trevor Harley is emeritus chair of Cognitive Psychology.

His primary research is in the psychology of language and consciousness.

Trevor Harley was born in 1958 in London and grew up near Southampton.

He was educated at Price's Grammar School, Fareham.

His undergraduate degree was in Natural Sciences at St John's College in the University of Cambridge.

He stayed at Cambridge to study for his PhD under the supervision of Brian Butterworth.

His PhD was on "Slips of the tongue and what they tell us about speech production".

For his PhD and later research he collected a corpus of several thousand naturally occurring speech errors, and focused on one word substitutes for another (e.g. saying "pass the pepper" instead of "pass the salt").

He concluded that speech production is an interactive, parallel process, leading him to an interest in connectionist modeling, and research on computational modeling, ageing, and metacognition.

After his PhD he took a temporary lectureship at the University of Dundee.

He then moved to the University of Warwick, where he stayed until 1996, then moving to a Senior Lectureship at Dundee.

From 2003 until 2016 he was Head and Dean of the School of Psychology at the University of Dundee, Scotland, United Kingdom.

He is author of several books, including "The Psychology of Language", currently in its fourth edition, published by Psychology Press, "Talking the talk", a book about the psychology of language (psycholinguistics) aimed at a more general audience, "The Science of Consciousness", a general text on consciousness, and "The Psychology of Weather", about how weather affects behaviour.

He is a Fellow of the British Psychological Society.

He was awarded a personal chair in cognitive psychology in 2003, and became head of department in the same year, and later dean in 2006.

In addition to his academic work, he is an author of a novel, Dirty old rascal (ISBN 9781445226224), a fantasy about a cook set in the strange Castle where no misdeed goes unpunished.

Harley has published an article, Why the earth is almost flat: Imaging and the death of cognitive psychology.

He has performed as a stand-up comic, performing at the Edinburgh Fringe in 2013.

Harley's current main research interest is in metacognition, an interest which grew out of his research on ageing and his interest in consciousness.

What determines how and why we act as we do?

This research is covered in his book, The Science of Consciousness.

Another of his research interest includes how we produce language, although he now studies this in the wider context of how we represent meaning, how language is affected by brain damage, and by normal and pathological ageing (e.g. Alzheimer's and Parkinson's diseases).

He also works on how we control our own cognition, and how this ability changes with age.

Underlying all his research is a belief that the mind is a parallel, interactive computer, best studied by experimentation and computational modeling.

As well as his interest in language and computational modeling, he was also interested in the research of ageing and metacognition.

He is also interested in the weather, and maintains a site about severe weather events in Britain and the British weather in general available from trevorharley.com, calling this role as a "psychometeorologist".

He also carries out psychological research about the weather, including why are people so interested in the weather?

He maintains a weather station at Newtyle near Dundee.

He discusses the effects of the weather on human behaviour in his book, The Psychology of Weather.

He wrote a famous article called Promises, Promises in which he argued that cognitive neuropsychologists have increasingly deviated from the original goals and methods of the subject.

One of Harley's most famous publications is the book The Psychology of Language.

In this book, he discusses psycholinguistics, which is the study of relationships that exist between linguistic behaviour and psychological processes.

Harley discusses both the low cognitive level processes, including speech and visual word recognition, and the high cognitive level processes that are involved in comprehension.

The text covers recent connectionist models of language, describing complex ideas in a clear and approachable manner.

Following a strong developmental theme, the text describes how children acquire language (sometimes more than one), and also how they learn to read.
