Here are a couple of articles:<br /><br />"Concordance for Stuttering in Monozygotic and Dizygotic Twin Pairs", Journal of Speech and Hearing Research, 24 (1981), pp.317-321<br /><br />This paper (written in 1981!!!) showed that there is a 73% concordance for stuttering in identical twins and 32% in non-dentical twins.<br /><br />Another paper from 1991:<br />"Genetic Factors in Stuttering Confirmed", Archives of General Psychiatry, 48, pp. 1034-1035<br /><br />In identical twins, there was a 20% concordance, and in the non-identical twins it was 5%.<br /><br />The figures suggest that genetics plays a role, but identical twins are (as the name suggests) identical, so their parents treat them in identical ways, and their environments are usually identical. However, the figures also indicate that environmental factors play a very significant role. If stuttering were purely genetic, there would be 100% concordance among identical twin stutterers ... but there isn't!<br /><br />You call it "random logical thoughts", I call it "questioning the current paradigm of stuttering research". The scientific literature that you cite is just a rehash of what has been done for decades. Nothing new has been found. The same questions that were asked 30 years ago are still being asked today ... zero progress.<br /><br />The same goes for brain imaging studies. No progress! <br /><br />My understanding is that the stuttering researchers are of an embarrassingly poor standard ... and something tells me that you agree with me.Rexnoreply@blogger.comtag:blogger.com,1999:blog-12602489.post-78115232905843318082009-05-16T20:30:00.000+02:002009-05-16T20:30:00.000+02:00The issue is the vague definition of a stutterer v...The issue is the vague definition of a stutterer vs. non-stutterer. <br /><br />Stuttering genes should not change with therapy or anything, it should always be there. Still don't quite understand the unequal female to male ratio??<br /><br />Why hasn't Dennis Drayna published anything on genetics of stuttering since 2004?? Not sure if he has made any Real progress or still trying....as to the location of the genes, when do you think it will happen? (what year, maybe 2020)<br /><br />Whole families of stutterers? Wow, how is stuttering defined, is a stutterer still a stutterer after successful treatment? If there are indeed whole families of stutterers, then it should be quite easy to find the stuttering gene, right?<br /><br />Thought the correlation factor was 0.4 to 0.6, weak correlation...BJnoreply@blogger.com
