Explain the principles of classical conditioning by describing pavlov's classic experiment with dogs.

Is the correlation among stimulus (one natural and another from the environment).

Explanation:

Ivan Pavlov, worked with dogs. He was testing a learning path in the area of conduct ism.

1.- First he tried a bell (this is the environment stimulus) to feed dogs (salivation is the natural stimulus).

2.- By passing the time, the reinforcement of the environmental stimulus make that the dogs start salivation just by the sound of the bell, does not matter if they have food or not.

3.- In this way he probed that learning  is based in following and repeating some conducts.

you must remain stopped until the stop signal is retracted and the red lights are turned off. approaching traffic in the opposite roadway of a divided highway shall not be required to stop, even if the school bus has the stop-arm extended and the alternately flashing warning signal lamps on.
