Ian Dury. Because… any excuse.
One of the best things about starting this blog was several e-mails I got from like-minded people saying nice things, and often, pointing me towards interesting bits of neurobollocks that I wasn’t aware of. Such was a series of e-mails from Deborah Budding and Michael Thaut (who must be one of only a few people in the world who holds posts as Professor of Music, and Professor of Neuroscience – cool) about the ‘interactive metronome’ technique. Michael’s research (unsurprisingly) focuses on the interplay between the brain and music, and in particular, the processing of temporal information as it relates to rhythmicity, so it’s probably fair to say he certainly knows his way around a metronome.
But what’s this interactive metronome business? Well, as you can see in this video on the hypochondriac’s website of choice (WebMD), it’s basically waving your arms about and moving your feet in time to a regular beat. So, it’s basically dancing then, but much more boring.
Surprisingly, given it appears to be such a simple technique, some people are claiming that it can have profound effects, and assist with various disorders such as ADHD, Parkinson’s, MS and even post-brain injury and stroke. The usual bunch of jokers with slickly-designed websites have sprung up offering treatment for all these things and more. The ‘How it works’ section of that website claims that the underlying deficit in a variety of disorders, claiming that the underlying dysfunction in ADHD, autism, dyslexia, Parkinson’s and others is just a ‘neural timing deficit’. The exercises used in IM correct the timing deficit, and therefore (supposedly) treat the disorder.
To say this is startlingly simplistic would be a massive understatement; it’s just plain wrong. The precise neurological issues in many of these disorders are difficult to pin down and are the subject of active investigation but, to take a simple example, we know exactly what the problem is in Parkinson’s; neuronal depletion in the substantia nigra. To claim that it’s some vague neural ‘timing’ issue goes well beyond disingenuousness and into the realm of outright deception.
There’s even a home-based version of IM therapy, that can be run on any computer – however the basic equipment (wiresless button boxes, tap mats for the feet etc.) and the software licence cost $800.
A PubMed search for ‘interactive metronome adhd’ actually produces five hits! However, on closer inspection, all five articles are seriously compromised in some way – studies with no control group, or with very low numbers. Interestingly, one of the papers that pops up is one I’ve discussed before in reference to Brain Balance Centers. So, IM appears to form a cornerstone of what the Brain Balance guys (chiropractic, with a thin layer of neuro-woo laid on top) are pushing too. The IM guys have gone to a lot of trouble to make their approach appear scientific – there’s a well-populated ‘Science’ section on the website, that contains links to lots of articles, however, many of them are ‘white papers’ of uncertain provenance, and the rest are articles from obscure journals, or on barely relevant topics.
Another problem with IM is that it gets conflated with serious interventions. There’s a large field of study focussed on the use and effectiveness of musical-type interventions for a variety of neurological disorders (broadly, called Neurologic Music Therapy, or NMT) that has some solid research behind it. The slick marketing of IM seeks to conflate their approach with much more high-standard music-based therapy approaches.
In Prof. Thaut’s words (my emphases added):
First, where is the research? Studies that back up the clinical effect of IM directly, are very rare or nonexistent. A small study from 2001 is one that comes up repeatedly. One small study does not build clinical evidence. IM seems in general a well marketed but unresearched application. From a research point I see no evidence for the therapeutic benefit of IM.
Second, brain mechanisms in therapy work differently. Possibly to fill the research void IM generously includes ‘borrowed’ research that has nothing to do with their device. Since I am one of the authors they use I have to clearly state that my brain research in music and rhythm does not address IM and our results do not support IM applications, neither with patients nor physiologically in explanatory brain mechanisms. The only forms of therapy in brain rehabilitation that work are active and specific exercises based on functional learning and training paradigms, not machine tapping.
Last, rhythm has its own life. The claim that tapping to a metronome improves timing in patients which in turn transfers to all kinds of cognitive and motor improvements is not only unsupported by research but seems based on a misunderstanding. Rhythmic synchronization is a very complex process that fluctuates continuously on a millisecond level and is inherently unstable and variable. This time flexibility is the actual hallmark of functional entrainment. Therefore the IM definitions and measurements of what constitutes rhythmic improvement seem physiologically and functionally meaningless.
So, there you have it. If you’re concerned about your child’s sense of rhythm (for some reason?) you’d probably be much better off signing them up for dance classes, or piano lessons. It’ll almost certainly be cheaper, and they’ll likely have a lot more fun too.
Neuro-Linguistic Programming – the 1970s neurobollocks that just refuses to die
I’d prefer to spend two days in a Siberian gulag than with these two smug bullshitters.
Neuro-Linguistic Programming (NLP) was invented in the mid-70s by Richard Bandler (a psychology and philosophy graduate) and John Grinder (a linguist). It originally grew out of observations made in therapy, and a metaphorical extension of some of the concepts of Chomsky’s transformational grammar. In the fertile grounds of the 70s Californian therapy and self-help movement, it soon blossomed into a multi-faceted set of techniques and philosophies. By the 80s it was being widely touted as a novel therapy technique and attracted some serious attention from researchers. However it was relatively quickly understood that there was no empirical basis for its key claims, and as its practitioners began to make ever more outlandish claims, serious interest from professionals waned.
This didn’t stop the NLP-faithful though. People like Tony Robbins (who studied with Bandler) made incredibly successful careers out of the motivational speaking/books circuit. Despite this undeniable popular appeal, NLP is nowadays widely-regarded as pseudo-scientific bollocks of a particularly refined and rarefied strain.
It’s actually quite hard to pin down exactly what the key principles of NLP are. This is partly because its founders and practitioners use such vague and amorphous language, full of metaphors and pointless jargon, but also because of the diversity of its supposed applications; from ‘traditional’ therapeutic settings, to sports coaching, to corporate training seminars, to (creepily) seduction. It aspires to include something for everyone; the best way to maximise the market and therefore the potential profit. One relatively common theme is focused on teaching communication skills in order to facilitate the learner’s personal and professional relationships. On the surface this sounds reasonable, but the communication theory that its based on has absolutely zero empirical support. The wackier variants incorporate all kinds of other bollocks like hypnosis, and many NLP-whackos talk about being able to ‘reprogram’ their own (and other’s) brain, often by claiming to influence the subconscious mind in some way.
Despite being nearly 40 years old, and a ridiculous, facile hodge-podge of concepts from psychology, philosophy, linguistics and new-age twaddle with absolutely no support from any reputable sources, amazingly, NLP is still very much alive and kicking. Bandler has kept on developing (and ruthlessly trademarking) a load of new techniques including ‘Design Human Engineering™’, or ‘Charisma Enhancement™’. A lot of his recent work also appears to include hypnosis. His website is essentially one big advertisement for his books, CDs and speaking gigs; and there are literally thousands of individuals, businesses, and ‘institutes’ offering NLP training for a bewildering variety of purposes and people. Bandler has even latterly jumped on the ‘Brain training’ trend with a new company called ‘QDreams‘ (‘Quantum brain training!’; ‘Success at the speed of thought!’ FFS…). Searching on Twitter turns up many, many people earnestly tweeting away about the benefits of NLP. Why is it so persistent? Partly this is because of Bandler’s clear talent for slick marketing, re-invention and dedication to innovative bull-shittery, and partly because NLP was never really clearly defined in the first place, which makes it highly malleable and adaptable to any pseudo-scientific new-age trends that come along. Despite a hiccup in the mid-90s (when Bandler tried to sue Grinder for ninety million dollars) it seems to be as popular as ever, and to be attracting new adherents all the time.
In my opinion the real stroke of genius in NLP, and perhaps the reason why it’s been so successful, is simply the name. These days we’re used to putting the ‘neuro-‘ prefix in front of everything, but back in the ’70s, this was way ahead of its time. Obviously there’s nothing remotely ‘neuro’ about it, though. Plus the ‘programming’ bit has a deliciously Orwellian appeal; promising the potential to effect change in oneself or others, if you just know the right techniques.
But effecting genuinely meaningful behavioural change in yourself is hard work. NLP derives from the quick-fix mentality of the self-help movement and is doomed to failure because of it. Does it actually help people? Perhaps, on some level, but any anecdotal results are almost certainly derived from a version of the placebo effect. Because of its vague nature, it’s not even really clear how its effectiveness would be meaningfully assessed anyway. Until we discover the genuine low-level programming language of the human brain we’ll probably always have to put up with this kind of bollocks being peddled.
There’s another really good article on NLP at the Skeptics Dictionary.
