Welcome to my site.

Keyword summary of content

Consciousness, Dreams, Weather, Language, Mental illness, Depression.

Short biography. I am Emeritus Professor of Psychology at the University of Dundee, Scotland, 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, and The Psychology of Weather. My latest book, The Science of Consciousness has just been published. My research interests are wide, including language, consciousness, sleep, dreams and their meaning, ageing, futurology, and psychology and the weather. I have suffered all my life from severe anxiety and depression, another topic of my research, and write, talk, and blog about it. I don't make any money out of this site. I provide it as a resource for people interested in the weather, consiousness, language, and mental illness. In general my research and interests are about how we can maximise and achieve our potential. I hope you find the site useful. Feel free to contact me at the email address below.

My novel Fit for a King, and more.

Language. Material related to my psychology of language books and psycholinguistics research.

Consciousness. Material related to my consciousness book The Science of Consciousness, and consciousness research, particularly sleep, dreams, and higher and altered tates of consciousness. Here you will find additional information, as well as clarifications and any corrections to the text, plus as many resources on consciousness as I have time to add. I have kept a dream diary for many years. I update these pages very frequently.

Weather. Information about severe weather events in Britain, recent weather, the British climate, and material related to my psychology and my book The Psychology of Weather, and research on that topic. How does weather affect our behaviour? I update these pages at least once a month.

Mental illness. My struggles with and my blog on mental illness.

Blog. Go straight to my blog on mental illness, whatisthemeaningofmylife, particularly depression and anxiety, and how they relate to trying to find meaning in life.

Chess. I am keen (if distinctly average) chess player. If you like chess or would like to learn how to play, and live in the Dundee region of Scotland, visit our Castelhill chess club site. We have many opportunities for playing online chess in the COVID crisis, and hope to resume over-the-board as soon as possible. I am interested in the psychology of chess playing, particularly at the sub-grandmaster level, and how we can all become better players - at any age.

Like everyone else I get submerged with spam, so if I haven't acknowledged your email within in a week or so the most likely explanation is that I missed it, so please just resend. I will answer all emails that I think are real (and not asking me for money) as soon as possible.

The software I use for putting this site together doesn't have a spellchecker (or at least one I can find) so there are almost certainly typos. I correct them as I find them but life without a spellchecker is surprisingly difficult.

I am a keen photographer and most (perhaps all) of the images on this site are mine.
