**Let's break it down:**Reinforcement - this is to

*increase*the frequency of a behavior. You are reinforcing the behavior.

Punishment - this is to

*decrease*the frequency of a behavior. You are punishing the behavior.

Negative -

*removal*of something.

Positive -

*addition*of something.

__Now we put them together:__All four examples will follow this model:

The (addition/removal) of something (desired/unwanted) in order to (increase/decrease) a behavior.

We know about addition/removal and about increase/decrease. The tricky part here is knowing when you are talking about something desired and when you are talking about something unwanted.

__Positive Reinforcement__

The

*addition*of something

*desired*in order to

*increase*a behavior.

__Negative Reinforcement__

The

*removal*of something

*unwanted*in order to

*increase*a behavior.

__Positive Punishment__

The

*addition*of something

*unwanted*in order to

*decrease*a behavior.

__Negative Punishment__

The

*removal*of something

*desired*in order to

*decrease*a behavior.

**A Bit More Information**If you are still confused about where desired / unwanted goes think of it like multiplication in math. (I know, ew!). Think of negative and punishment as negatives. Think of positive and reinforcement as positives.

With desired being positive and unwanted being negative you can solve what goes in what definition.

Two positives make a positive.

One of each is negative because it "overrides" the positive.

Two negative make a positive.

Example: let's use

*negative punishment*. You know negative is removal and punishment is decrease already, so you have 2/3 words. Now, negative and punishment are both negatives in our math equation. And what do two negatives make? A positive! Therefore you know that negative punishment is the removal of something desired in order to decrease the frequency of a behavior.

If you look back at the above examples you will see that it works. Finally some use for math!

I hope this made some sense to you wonderful people!
