They would see like this metal object that was a sample. Didn’t matter what the object was, of course, it was just something that they needed to remember and needed to know that they had to remember it. And they would then, you’d pull up the door and they would knock it aside, and know there was gonna be a little raisin as a reward in there and they got it. And then you put it down and you put out another thing, a sample plus another, not a sample, but another one like that, and plus a different one. And you let them choose which one they were gonna get, they would choose. And they had to remember that it had to be that one that looked like the sample was gonna be their reward. And you left, and time. You know, you had to take a longer and longer time and see how long they could remember it, but they did that extremely well.
