On this website are four papers that I have published on neuro-linguistic programming. The most recent of these (Heap, 2008) appeared in the Skeptical Intelligencer and in that paper I synthesise and expand on three previous papers (Heap, 1988a, 1988b, 1989) in which I reviewed evidence for the doctrine of 'representational systems' as espoused by the originators of NLP, Richard Bandler and John Grinder. (I must emphasise that I myself have undertaken no experimental work on NLP: I have simply reviewed the work of those who have. If you are only going to read one of these papers then it is the 2008 one that you should choose.)

The three earlier papers that I have uploaded are in pdf format and I apologise that some of the pages have been scanned rather lopsidedly.

My 2008 paper was one of three articles on NLP that appeared in the Skeptical Intelligencer of that year. The second of these articles was a rejoinder to my papers and is authored by Andy Bradbury, an expert on NLP, who emailed me in 2008 to challenge the conclusions of my early review papers. Andy very kindly agreed to provide his comments and criticisms and to outline what he considered to be the correct representation of the issues that I raised in my papers. The third paper is by Mark Newbrook, who presented some of his thoughts on NLP from the standpoint of a linguist ('Linguistic aspects of "neuro-linguistic programming"'). All issues of the Skeptical Intelligencer, including the 2008 one, may be accessed at the members' section of this website.

As I explain in my paper, I became interested in NLP in the early 80s. I recall much excitement at that time amongst psychotherapists, particularly those who used hypnosis, because NLP was being promoted as a revolutionary breakthrough in delivering fast and effective therapy. Very much allied to this was a fascination with the American psychiatrist Milton Erickson who was well known for his work and publications on clinical hypnosis. Erickson died in 1980 but in the years prior to this, his home in Phoenix, Arizona became something of a Mecca for young psychotherapists wanting to know how he achieved his therapeutic outcomes, which according to a number of publications around that time, were quite remarkable.

Well, like many others I rushed about hither and thither, attending workshops and meetings in the UK and abroad finding out more about these exciting developments, and I read quite a number of the early NLP and Ericksonian texts (most of the latter having little or nothing to do with NLP). These included Trance-Formations by Grinder & Bandler (1981; see my paper), a book on the therapeutic practice of hypnosis that has some interesting ideas and some odd ideas.

One idea from NLP that intrigued me was the doctrine of representational systems, namely that at any time the way we are representing our world cognitively is characterised by one of five sensory modalities (visual, auditory, etc.). It is contended that the dominant modality is signalled by certain behavioural indices, notably verbal expression and eye movements, and that people have a preferred representational system.

All of this seemed like the kind of information that should have been appearing in textbooks on cognitive psychology, and its absence therefrom puzzled me. Moreover, from my reading and my attendance at talks by NLP practitioners I could not ascertain how these observations and generalisations about the human mind had been derived. I recall broaching this with the leader of one workshop I attended, an earnest young American gentleman who exuded much self-confidence. Throughout our conversation he looked at me intensely and I suddenly realised that whenever I uttered the word 'yes' he flicked his forefinger up. I came away none the wiser.

Later I spent a lot of time in the University of Sheffield library (before the days of Internet searches) and was surprised to find that there were quite a number of experimental studies of 'representational systems', albeit mainly in the form of dissertation projects by postgraduate students.

Thus I came to write my review papers. I have given a detailed account of all this in my 2008 article. Andy has, metaphorically speaking, rolled up his sleeves and given me a thorough beating in his paper, for which I am very grateful. The full reference is Bradbury (2008) Neuro-linguistic programming: Time for an informed review. Skeptical Intelligencer, 11, 14-27. I don't think it useful for me to provide any rejoinders to Andy's criticisms here. Let his words speak for themselves!
