One person who used the ABX test for a group evaluation wrote: "... several of us noted that we had great difficulty remembering what A had sounded like by the time we got through with X." The conclusion here is that ABX is stressful and thus confusing. However the very experienced ABX tester Thomas Nousaine, endorsed by ABX spokesperson Arnold Krueger, has expressed the alternative view : ABX is not stressful enough. Nousaine: Actually people perform their BEST under stress. It is the human condition...when the lion growls we attain maximal sensitivity! Nousaine: Actually putting a gun to your head would ensure that IF real differences were present you would be able to hear them. Nousaine again: I'd say that if IF someone held a gun to a subjects head threatening to shoot him when he failed to reliably report the presence of a given sound the subject would be most likely to respond correctly when the sound was actually a real phenomenon So here's an outline of the new improved ABX+ First, select the two components to be tested. Lets call them "A" and "B." Group tests are fallible - so tests should be performed on an individual basis. Testees should therefore be kept in a waiting room and called in one at a time. To prevent subjects from being influenced by overhearing tests hearing should be masked with headphones or tape. As each subject is called out they should also be blindfolded and gagged to prevent bias and communication. To maximize sensitivity, gag first, produce your firearm so they can see it, *then* blindfold them. Now you can remove their headphones and whisper "if you answer any question incorrectly I will shoot you in the head". Bind them to a chair in the "sweet spot" using rope or chains and proceed with the testing.... Play snippets or A and B in a random order, and ask them to identify which one is X. Those who survive get to make a better informed shopping choice. wrong!!!!! eyeball gouging and electrodes on one's testicals were not included. -- S i g n a l @ l i n e o n e . n e t |
