Hello Dr Rutherford, good of you to finally turn up & explain things, especially after what you said about me in the Guardian comments section. Always happy to learn something new, so if you'd like to correct anything else I've written, here or on my blog, I'd welcome the discussion and be happy to correct any inaccuracies you can find. I don't delete blog comments except obvious commercial spam or swearing (messes up my access), so feel free to suggest corrections to my 'ill informed, based on limited knowledge, biased ... extremely damaging' blog too if you'd like
Please could you provide a link the your comments on the 'Life Matters' radio programme? I take it you mean this programme, but I'm not able to spot your comments.
To clarify, Reynolds & Nicholson (2007), as with all the 'Balsall Common' studies, included only ONE CHILD with a diagnosis of ADHD. On the basis of this one child, for whom individual results are not given in any of the papers (so we don't actually know what the programme did for this child's ADHD), Dore ran 'Google Adwords' advertisments:
'Proven Drug-Free, Exercise Based ADHD Remedy'
That sounds to me an awful lot like suggesting you can cure ADHD, and
have proof to show you can. I've made a complaint to the ASA on this
basis, last I heard it was still under investigation - don't know
whether it will continue despite the financial crisis.
There were other Google adverts linking to Dore stating:
Proven Drug-Free,
Exercise Based Dyslexia Remedy
Proven Long Term Drug-Free
Solution Relieving the Symptoms of Aspergers
Proven Long Term
Drug-Free Solution Relieving the Symptoms of Dyspraxia
Dore promotional material included such claims as:
'have
developed a programme which can transform the lives of those suffering
with specific learning difficulties like dyslexia, dyspraxia, or attention
deficit and hyperactivity disorder'
all based on similar levels of 'evidence'. It is simply not legitimate to claim 'proven' on the basis of literally a handful of children, or no published research whatsoever in the case of Asperger's syndrome.
Reynolds and Nicholson (2007) did NOT consider their study to be proof that 'cerebellar treatment' underlay any changes observed in the 'Balsall Common' studies. The very paper you cite makes this abundantly clear in the abstract:
Further research is needed
to determine the underlying reasons for the benefits. Possible (and potentially synergistic) explanations include: improved cerebellar
function (neural level); improved learning ability and/or attentional ability (cognitive level); improved self-esteem and self-efficacy (affective level); and improved parental/familial support (social level).
FWIW, my own (unpublished undergraduate dissertation) research looked at 12 very high-functioning dyslexics, and 12 controls. 'My' dyslexics were all at university and doing well academically, none had an ADHD diagnosis. One of the few ways in which they tested out differently to their non-dyslexic peers was scoring significantly higher on an ADHD screening tool (ASRS short version). This suggests to me that sub-clinical differences on an ADHD screening tool are not particularly important in determining later academic achievement. Of course, I'd not want to draw firm conclusions from a small pilot study with 24 participants (12 dyslexics), but that's not so different from Balsall Common with 35 participants (6 dyslexics).
It will not be possible for a fully independent study to be carried out on the Dore programme until Dore cease to use 'commercial confidentiality' as a means to prevent independent research by people not of Dore's choosing.
Could you perhaps explain what exactly Prof Coltheart said which was 'totally untrue'? There's a full transcript online, so it would not be difficult for you to provide specific examples, particularly since you state that he 'has been corrected' - I'd be interested to read those corrections, if you could please provide them?
I tend to think that it's a rather weak argument to point to the qualifications of your opponents, rather than arguing the issues. However, since you raise the matter, I believe you trained as a GP, and have yet to complete the PhD you began, supervised by Prof Nicholson who co-authored the 'independent' study to which you referred above? Web Of Science doesn't come up with any publications for you, unless you find time out of your busy life to write for the 'Journal of Real Estate Finance and Economics' or perhaps 'J. Applied Entomology' - perhaps I have missed something here, 'Rutherford, R.' seems to be quite a popular name, there's also a Rutherford RB who publishes in Ed Psych but seems to be based in America - if so please do enlighten me?
Prof Coltheart's rather impressive publication list and CV may be found here, and as I have already indicated on this thread he has received several indications of esteem. Both Tu Quoque and Argumentum ad Verecundiam are logical fallacies, and since I don't even have a batchelor's degree yet I'm hardly arguing for them - but an ad hominem attack on Coltheart as 'clearly out of his depth' is spectacularly unconvincing without further supporting information. Kindly provide such, or retract your accusation.
I'll address the second paragraph in another post, since this is getting a bit long - TBC...
