The good thing is that you don't have to know what it is called to use it properly.
But sorry, you would have failed the class I taught on Operant and Clasical conditioning in College.
Now Richard what makes you think I am not an educated man? lol
Look last time for you.
Nothing is being trained into the dog but for him to learn command means MOVE.
But if you want.
Here is a long run of how combine it all.
Avoidance Conditioning - Combining Classical and Operant Conditioning
By some flunky out there... <img src="/ubbthreads/images/graemlins/tongue.gif" alt="" />
Classical and operant conditioning often take place in the same situation.
We saw this in Rescorla’s fear conditioning experiment: Presenting a CS while dogs jumped back and forth to avoid shock increased or decreased the rate of jumping.
In Rescorla’s experiment, the avoidance procedure (operant conditioning) had no warning signal for the shocks; they came at certain times.
In another type of avoidance procedure, signalled avoidance, there is a warning signal before the shock.
If there is no avoidance response, the warning signal ends with shock.
Signalled Avoidance
Warning signal (tone)
Aversive stimulus (shock)
Avoidance response
Note that the warning signal is paired with shock. This is classical conditioning. The tone will become a CS and produce a CR of fear.
Signalled Avoidance
Warning signal (tone)
Aversive stimulus (shock)
Key Point: The warning signal will become an aversive stimulus because it produces a fear CR.
Signalled Avoidance
Warning signal (tone)
Aversive stimulus (shock)
Aversive stimuli are negative reinforcers. They reinforce responses that remove them.
If the avoidance response occurs before the shock, the tone goes off immediately and no shock is given on that trial.
Signalled Avoidance
Warning signal (tone)
Aversive stimulus (shock)
Avoidance response
Removal of the aversive warning signal negatively reinforces the avoidance response.
Signalled Avoidance
Warning signal (tone)
Avoidance response
The avoidance response occurs faster and faster on later trials because it receives negative reinforcement.

The 2-Process Theory of Avoidance Learning
Avoidance behavior is not reinforced by avoidance of the aversive stimulus!
It is reinforced by termination of the warning signal.
Process 1: Classical Conditioning: The warning signal becomes aversive through pairings with the aversive stimulus (fear conditioning).
Process 2: Operant Conditioning: Avoidance responses are negatively reinforced by termination of the warning signal.
The 2-Process Theory of Avoidance Learning
Key prediction: Delay of reinforcement weakens behavior. When an avoidance response occurs, if the warning signal goes off after a delay, the avoidance response should occur less often.
Pros
Warning signal (tone)
Avoidance response
Delay of reinforcement
This prediction was supported (Kamin, 1956).
The 2-Process Theory of Avoidance Learning
1. Unsignalled avoidance: Avoidance learning can take place without a warning signal (e.g., Rescorla’s experiment).
Cons
2. No extinction of avoidance response: Avoidance responding should stop because the warning signal is not paired with shock on these trials, but the avoidance response keeps going. Why?
Cognitive Theory of Avoidance Learning
The subject forms two kinds of “expectancies”:
1. Stimulus-Outcome: Warning signal leads to shock if there is no response.
2. Response-Outcome: Avoidance response leads to safety (no shock).
To weaken avoidance response, these expectancies must be weakened through disconfirmation.
Avoidance response keeps going because
Expectancy #1 not tested and
Expectancy #2 is repeatedly confirmed.
Supporting evidence: Response Prevention ( “Flooding&rdquo
procedure. It’s used to eliminate an avoidance response when there is no longer a threat of being shocked.
Physically prevent the subject from making the avoidance response while the warning signal is on.
New expectancies are formed:
1. Stimulus-Outcome: Warning signal leads to NO shock if there is no response.
2. Response-Outcome: NOT responding leads to safety.
So you see a combination of CC and OC as friends but not lovers.
A dog teaches a boy fidelity, perseverance, and to turn around three times before lying down. - Robert Benchley
In order to really enjoy a dog, one doesn't merely try to train him to be semi-human. The point of it is to open oneself to the possibility of becoming partly a dog. - Edward Hoagland
