Document Summary

There is an aha moment when the cat realizes where the lever is and that it is escape. Actions followed by a pleasurable consequence will tend to be repeated. Actions followed by an unpleasant consequence will tend not to be repeated. Voluntary behavior is what people/animals do to operate in the world Voluntary behavior is operant behavior, and the learning of such behavior is. The key to operant conditioning is the effect of consequences on behavior. Learning depends on what happens after the response - the consequence. Reinforcement - anything that increases behavior and some behavior is more likely to occur. Positive reinforcement - pushing lever to get food. Negative reinforcement - pushing lever to get rid of some stimulus (electric shock) Graphic summary of mouse"s behavior responses over time. Initial stage of learning when a response gradually increases due to contingent. Reinforcement of closer and closer approximations of the desired response.
