Trevor Harley


I am Emeritus Professor of Psychology in Psychology in the School of Social Sciences at the University of Dundee, Scotland. I was formerly Chair of Cognitive Psychology at Dundee, where I was Head of Department and then Dean, from 2003 until 2016. I am now a full-time writer, science journalist, and public 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 I write, talk, and blog about it. For a longer biography see About me.


About me. See here for a longer biography and more information about what I do. See here also for more information about my media appearances and what I can offer, including consultancy on the science and psychology of self-improvement, and my occasional work as a stand-up comic. I talk frequently in London on the meaning of dreams and on mental illness.


My research. See my research page for information about my psychology research, including work on sleep and dreams, consciousness, metacognition, depression, language, ageing, futurology, and the weather.


Psychology books. I’m the author of several books, including the text The psychology of Language (4th edition, 2014), Science and Psychology (published 2017, with Richard Wilton), and Talking the talk: Language, psychology and science (2017 for the second edition). I am editor of two series of books on the psychology of language. I was writing a book on cognition, but this has mutated into a book about consciousness, called The science of consciousness, to be published by CUP USA next year. I am also writing a book on Psychology and the Weather, now published by Routledge. See this page for more about my psychology books, including a link to errata for The psychology of language.


Novel. You can now buy my novel Fit for a King for Kindle and compatible devices at Amazon, as well as the paperback version. It's a genre-defying murder mystery psychological thriller fantasy love story.


Weather. See this page for links to my site on the weather of Britain, with information about severe weather events in Britain. Want to know what happened in the weather in a particular month? Which are the hottest and coldest summers and winters on record? See below for my research interest in psychology and the weather.


Depression. See here for my work on depression and my experiences of being depressed. I am currently writing a book about depression, provisionally entitled "No birds sing". See also my blog.


Blog. My blog on the psychology of the meaning of life is available from What is the meaning of my life?. There are several blogs on depression, anxiety, meaning, and existentialism. The main focus of the blog is on a psychologist (me) struggling with mental health issues, particularly depression, anxiety, and OCD, while trying to live a fulfilling life. What is a fulfilling life, and how can we cope with existential despair and a fear of death? I post regularly.


Consciousness. See here for details of my forthcoming book, The Science of Consciousness, and related material.


Photographs. A selection of my photographs (mostly landscape).


Web design. I built this site in Apple iWeb and maintain it myself, now using Adobe Dreamweaver. The transition has not been without its difficulties.
