I believe that there are some inaccuracies in this article. I don't have the time right now to fix them properly, but if anyone else wants to try, this is what I think should be addressed: (1) "A stimulus that is less intense than the sensory threshold will not elicit any sensation." Thresholds are often defined as the inflection point of the psychometric function. Thus, there is a good chance that a below-threshold stimulus will elicit a sensation. (2) "It is most commonly applied to the detection and perception of flavours and aromas" This is very biased. Opthalmologists and optometrists perform threshold measurements every day with thousands of patients. Similarly, auditory thresholds are tested very frequently by ENT doctors. Compared to that, "flavours and aromas" is just a tiny fraction, I'd guess.--Dontaskme 11:14, 8 November 2006 (UTC)
