OK, i was refering to a test of antibiotics or cholesterol drugs , for example. The results can be determined by blood tests, the cholesterol is lower or not, the infection is gone or not. It is irrelevant if the subject says he feels better(the placebo effect) in these tests. So blinditis would not invalidate those tests. I never said that there would only be a psychological effect in blind trials. Any number of factors could affect the hearing performance of the testee. The pressure of the test itself can affect listener performance, and that does not repudiate medical testing which doesn't rely on the subjects subjective assessment. I will ask some colleagues if there are any studies on ear training tests. ie. whether a graded test gives different scores than an ungraded test. -- tomjtx ------------------------------------------------------------------------ tomjtx's Profile: http://forums.slimdevices.com/member.php?userid=7449 View this thread: http://forums.slimdevices.com/showthread.php?t=29353 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
