Identity

I have just come across a very interesting article at http://www.stammering.org/heidi4.html and Heidi who has had some success with the SpeechEasy device says, 'therapy support has been vital for me, in order to explore who I am now that I don't stammer so much'.

This supports my last post, I think.

But use anything that helps apart from drugs.

As for the rest of the article: I have reservations about how people interpret brain imaging - I do it for a living. The main thing to remember is that evidence of association is not evidence of causation. What comes first: the function or the structure? And imaging may show which structures are associated, or not, with a behaviour. Occasionally there is a structural abnormality which is clearly seen: as in some cases of epilepsy and tumours.

Shyness, anger and depression may show changes in in imaging but does that mean there is a 'causal' relationship? Very rarely.
