 All right, here we go anyway symmetry. We're talking about stimulus equivalents. We're stocking we're stocking match to sample procedures I don't know how you stock a match to sample, but you could maybe I suppose keep them all in the file. I'm stocking Yes, I'm stocking So he's not that young anymore should stop calling it So symmetry a equals B B equals a right so you teach something to say where you go The letter a is going to get you to say letter B Right, so then we test to see if the organism has symmetry by presenting the letter B Do they have a right so I can teach that relationship from A to B like showing you a picture of a car and having you Choose a truck then Ideally I should be able to show you a picture of a truck and have you choose a car that would be symmetry You've made those two things Equivalent functionally speaking get what we're doing here right so equivalent stimulus equivalence training So if a equals B, then we test to see if B equals a if B equal if B does equal in the organism response correctly We say they quote-unquote and I say quotes here have symmetry. Yeah, they're displaying symmetry. I don't have nothing
