In September I gave a workshop at the annual meeting of the Association for Pet Dog Trainers, always both an honor and a pleasure. In the workshop I demonstrated an exercise I'd learned, at an earlier APDT meeting, from Massachusetts trainer Tibby Chase, for teaching inattentive dogs to walk politely at a person's side. The exercise involves targeting and shaping, and works even if neither the handler nor the dog know anything about clicker training. APDT had arranged for a pet owner to bring three friendly but largely untrained dogs. None of the dogs were accustomed to being in public, and while they were fairly quiet they were of course trying to smell everything and greet everyone, pulling on their leashes and paying very little attention to the person holding them. The owner found a volunteer handler for each dog so I could put them through the exercise, one at a time.

The Limited Hold
By Karen Pryor on 11/01/2006The limited hold is scientific terminology—laboratory slang, really—for a good way to use the marker and reinforcer to speed up response to a cue. We're all used to sluggish responses. You call folks for supper, and in due course, they come; meanwhile the soufflé falls or the soup gets cold. You call your dog to come in the house and it comes, grudgingly, finding half a dozen new things to sniff at before actually reaching the back door. Here's how you can fix that.
The Beginners' Clicker Class
By Karen Pryor on 10/01/2006What is a beginner clicker class? Is it an ordinary six-week long basic pet owners' obedience class, with clickers added?
I don't think so.
Jackpots: Hitting it Big
By Karen Pryor on 09/01/2006Jackpots!
A good thing? A bad thing? A nonexistent thing?
Let me tell you what I mean by "jackpot." I mean exactly what the casinos mean: a surprisingly big reinforcer, delivered contingently. The key is in the word, contingent. To reinforce a particular behavior, a jackpot has to appear, and be perceived by your learner, while the learner is doing that particular thing you want. Not afterwards.
Charging the Clicker
By Karen Pryor on 08/01/2006At an annual meeting of the Association for Behavior Analysis, where over 2,000 behavioral scientists gather each year, a woman professor with whom I was acquainted told me she had organized, among her students, a Rat Olympics. I was excited! What a good way to interest students in operant conditioning!
