Negative reinforcement is the act of taking something away in order to encourage a certain type of behaviour.

One scenario is a parent letting a little girl skip washing the dishes because she got a 100% on a test. The reinforcer is the parent, and the desired response is good marks on the girl’s tests.

With negative reinforcement, you are increasing behavior, whereas, with punishment, you are decreasing a behavior. The following is an example of negative reinforcement: Bob does the dishes ( behavior ) in order to stop his mother's nagging ( aversive stimulus. ) Hope this helps. Have a great day!
