The correct answer is The behavior will immediately increase in frequency, but then decrease over time.
Any type of stimulus or situation that occurs afterwards (contingent) the answer that increases the future probability of the response occurring. <u>There are two types of reinforcing stimuli:</u> A) Positive, not in the sense of good or bad, but in the sense of addition, we will have a positive reinforcer when the answer is followed by the addition of something, for example: I turn on the tap (answer), water falls (positive reinforcement stimulus), I tell a joke (response) my friends laugh (positive reinforcement stimulus), I do well in the test (response) and receive a compliment (positive reinforcement stimulus) there is always the addition of something, consequent the answer. B) Negative, too, not in the sense of good or bad, but significant the withdrawal of an event after the response, for example: I turn the fan (response) off the wind to (negative reinforcing stimulus), I put my finger on the socket (response) and quick shot when taking shock (negative reinforcing stimulus), etc.
