given/added

Taken away.

Explanation:

When conditioning a behavior, there are two ways to make a person learn. One is by using reinforcers and the other is by using punishments.

A reinforcement is an stimulus that increments the probability of a response.

On the other hand, a punishment is an stimulus that decrements the probability of a response.

Both of them can be positive of negative

Therefore, the main difference between a positive and negative reinforcer is: a positive reinforcer means something is given/added and a negative reinforcer means something is taken away.
