yesterday you asked your friend ray for a couple of aspirin tablets to relieve your headache. ray has been taking a psychology course and informs you that, in behavioral terms, aspirin is a reinforcer.

The correct answer is a negative reinforcer.

Explanation:

In psychology there is a type of procedure called reinforcements. This means that there are situations in which certain behavior is established or eliminated, waiting for a response because of doing it.

There are two types of reinforcements: positive reinforcements and negative reinforcements.

The positive reinforcement establishes that by means of a certain type of behavior, a positive response will be expected, therefore the behavior will be repeated again to have that response again.

An example of this would be when you teach your dog to sit, and in return you give him a croquette. The first time he did it, the dog saw that he received a delicious croquette in exchange for his action, so he is likely to do it again in order to win a croquette again.

A negative reinforcement, on the other hand, is one that eliminates a certain type of negative condition, waiting for the response to this to continue. As is the example of taking an aspirin. If a person takes an aspirin to relieve his headache, it is likely that every time his head hurts he will take one too. And this is not a positive or recommended behavior, unless a doctor prescribes it.
