 It's the emergence of factors, blah, blah, blah, blah, blah. All right? Whatever. Stimulus equivalents. We're establishing equivalents between multiple stimuli, often known as stimulus-stimulus relations and that sort of stuff. So, are we going to blah, blah, blah, blah, blah, blah? We're going to demonstrate things like reflexivity. We're gonna demonstrate things like symmetry or transitivity. If you can do all of those three things, then we have the full-blown stimulus equivalents. But what we're talking about here is really getting a particular stimulus to evoke the same responses as another stimulus. But the second stimulus has to be an untrained one, so on and so forth. We're just going to make two things mean the same thing to an organism in terms of the responses that they evoke. Notice I did not say elicit because we're talking about operant conditioning, not respondent. So, stimulus equivalents, operant conditioning. See more videos.
