Not sure I necessarily agree with the above, the journal is in some cases paid for the publication of articles, in addition they may not necessarily be custodians of the research merely a conduit.
there have been a number of studies performed into the playing of an instrument and the correlation with higher IQ or boost in IQ. Some research seems to indicate that playing an instrument raises IQ (although I believe this to be a temporary thing for as long as one actually plays through life) .
But of course, you may be absolutely correct and its all completely unrelated to IQ ...but I doubt it
I don't think we disagree. IQ undoubtedly plays a role here and whether the link between IQ and musicianship is causal, correlative or mere coincidental is a topic for another study. I just don't share your mistrust of the journal in question. Sure, there are journals which have dubious reputations arising from them publishing what brings them money rather than what is accurate, but this is not one of those journals.
This study will have been subjected to peer review before it was published in Neuropsychologia. What that means is that guys much smarter than you or me have already scrutinised these findings and have given it the nod. You'd need some hefty credentials to be able to simply diss the findings with "naah, it's all just IQ".
