Not even close. I'll leave it to Chris Green or an S&P person (do psychophysicists even exist anymore?) to really hammer you on this but Ernst Weber introduced the notion of the JND in the form of the Weber ratio and Gustav Fechner used it as the basis for his logarithmic law. Wikipedia (standard disclaimers apply) has an entry on JND which provides some of the background: http://en.wikipedia.org/wiki/Just-noticeable_difference A more up to date treatment of the problems involved here are provided by Neil Macmillan and Douglas Creelman in their "Detection Theory" (the first edition is available on books.google.com at: http://books.google.com/books?id=Pfw3AAAAIAAJ&pg=PA25&lpg=PA25&dq=fechne r+%22just+noticeable+difference%22+threshold&source=bl&ots=w8vdK0u6PF&si g=R8tBx7-C6pybzCOssAEF5JByvfo&hl=en&ei=ktfASt2MBNDRlAfKt-iwBQ&sa=X&oi=bo ok_result&ct=result&resnum=10#v=onepage&q=fechner%20%22just%20noticeable %20difference%22%20threshold&f=false or http://tinyurl.com/ydxsasg ) or George Gescheider's "Psychophysics: The Fundametnals", the 3rd edition is available in limited preview on books.google.com: http://books.google.com/books?id=gAFtxKQI1mAC&pg=PP1&dq=psychophysics#v= onepage&q=&f=false or http://tinyurl.com/ybceyj6 >and I find myself trying to see how those constructs could be applied to >interpreters at the United Nations.My observation is that women interpreters >seem to provide a more understandable English translations than men >interpreters.
