"He has been pricked and prodded, hooked to electrodes and even lie-detector tests by well-meaning scientists around the world interested in his special case."
- a quote about Daniel Tammet from the book and also the blog about famous synaesthetes both titled Tasting the Universe by Maureen Seaberg http://www.psychologytoday.com/blog/tasting-the-universe/201205/daniels-eyes-china-blue
Sounds most interesting, but sadly, Seaberg gives no details about this testing of Tammet, and I've been unable to find any info about lie-detector testing in the scientific literature. If you can help with more info on this topic, I'd love to know. I find it rather hard to believe that anyone worth the description of "scientist" would administer or even recommend a lie-detector test, as it is my understanding that they have no scientific credibility.
