I've gone to the local CVS and asked the photoshop to save black film canisters which I then fill with various amounts of sand that differ by 1 gm each (one is actually empty and I move up from there). If I remember correctly (its been a while), my sets of canisters have about 25 each. If you make enough sets you can have students pair up, remove all jewlery from hands and run the study. The rule is that they must detect a difference correctly 5 consecutive times in order to count. Every time they miss one the comparison stimulus goes up by one. Next I have them repeat the entire procedure with #2 as the standard stimulus of comparison. By they way, the standard stimulus may appear in EITHER the left or right hand which is held horizontally, palms facing up, and the hand presentation is up to the "researcher" student, and the "participant" student must keep his/her eyes closed. The "participant" is also told NOT to grasp the canisters, and to only gently move their hands up and down to attempt to detect the difference. This way they can't hear sand moving. That said....I've found that this exercise usually works about 70% of the time. This seems to be good enough for the students, as those for whom it doesn't work seem to be really motivated to determine exactly why it didn't work for them! The prep time is considerable, but you've only got to do it once. Hope you find that helpful. Cheers, Rob Flint --------------------------- Robert W.
