now what times we see a behavior, and we think there's no way i could get my dog to do that, Because the behavior may seem kind of complex, Like for instance, This draft behavior, Well, usually when people say that i think, Well, Of course you can't train that in one step, What you need to do is start with a behavior, You can get and reward that, and then systematically trained behaviors closer and closer to your goal behavior, In other words, what you're doing is you're shaping behaviors through little steps called successive approximations, so here's an example, In other words, were shaping behaviour through little steps called successive approximations, here's an example of how you might shape a behavior, such as teaching a dog to suffer, you could first teach the dog to her target in front of her nose when she touches it, Give her a three, when she's good at this step, Next reward her only for catching the target held down lower, when she's good at this step, Only reward her for touching the target between her legs, and if you continue to increase the criteria in this manner by little steps, you'll eventually get a summer salt, in this program will use many simple steps to build up to our goal behaviors, It's best to go through all the steps that you and your dog experience, Lots of success, rather than skipping ahead and having to go back to repeat steps later on, so we're going to shape behaviors through little steps called successive approximations, Now, a lot of times they come up with this great shaping program, and then suddenly they get stuck, Well, there's always three reasons, It's always one of three reasons why we get stuck, First of all, One of the most common reasons is that you went to the next step too soon, So for instance, just because a dog can do something a couple of times doesn't mean it knows it really well, It's just like if you are doing math or chemistry, And you were able to do the problem a couple of problems, It doesn't mean really not well enough to take a test, So what we say in general is that for research purposes, you would say, well, i don't want to go onto the next step until my my dog gets at eighty or ninety percent correct in real life, You might say, Oh, i need to do five times in a row before i can go to the next step, or i'll say i had to bet myself a lot of money and that my dog will be able to do it right the next time, If i want to go on,
