This week’s episode explores the stimulus control quadrants developed by Dr. Jesús Rosales Ruiz. When I say stimulus control many of you are probably thinking about the four criteria that are used to judge if a cue is under full stimulus control. This is not what Jesús is talking about. He’s looking instead at the conditions under which learning occurs. It’s a fascinating discussion. Don’t fight extinction is an important part of the stimulus control quadrants. You can find out what this means in this week’s episode.
