We also learn to make things happen. In other words, we behave in certain ways to produce an effect. This type of learning is called operant conditioning. Responses that produce an undesired effect are less likely to occur again. The US reinforces the CS which strengthens the CS-CR behavior.
Response precedes the reinforcer.
Presence of the reinforcer is independent of the response. It also changes the probability of the response. Positive Reinforcement - occurs when the arrival of some stimulus following a response makes it more likely to occur. Negative Reinforcement - occurs when the removal of some stimulus following a response makes it more likely to occur. Adjust the radio dial to eliminate static 2.
