Silly me. By the time I stumbled across that Iranian article which claimed it doesn't occur, I had forgotten all about Dennis Goff's citation of the Purves article, or perhaps it never registered. Still, we have a problem. We have two Iranian physicists claiming in a respected Western journal, _Perception_ (to show my Eurocentric bias), that in 2003 they were unable to observe an effect reported by three American neurobiologists in 1996 in an even more respected journal. Moreover, the Americans reported the effect to be highly reproducible: 11 of 12 na�ve observers saw it too. So why not the Iranians? The next step must be to check what the Iranians had to say. We don't get the journal here but they provided an e-mail address. I guess I'd better write them. How'd they get time off from making atomic bombs, anyway? (sorry, I never said that!) (This reminds me of the title of a paper I once saw published, I think, in _Psychological Reports_, "California women know that the surface of still water is horizonal".)
