 Stimulus. That was weird. Stimulus preference assessment. Which would you like to earn that? That. Or this pen or that pen? Which one would you like? Oh, you like the candle? Okay, we'll set that over here. Okay, out of those things. And so now that we've got that out of the way, which one of these things would you like? The shoe? I can understand why. It has a nice odor. Anyway, so there you go. All right, so we've done a stimulus preference. So the stimulus preference is in the pen. Okay, the pen. All right. So anyway, the stimulus preference assessment is just that. Which stimuli do you're asking someone? Which stimuli would they prefer to earn? Which one would they like to have? Which one would they like to play with? Which one would they like to touch and mess around with? Right? It doesn't mean that those are going to be reinforcing. It just means that these are the stimuli that your particular learner and the person you're working with seems to prefer at the moment. This is going to give you an idea of what might be able to reinforce the behavior. And we'll talk about that later in another video. Anyway, see you at stimulus preference assessment.
