Positive reinforcer

When I took psychology I had trouble remembering positive and negative reinforcer, so I'll just give you a quick explanation in case you needed it

I remember that positive reinforcer means you add or give something to encourage a behavior or whatever. That one is pretty easy to remember, but if you are learning about positive reinforcement I can assume that you are also learning about negative reinforcement and punishment. I would always get confused with negative reinforcement and punishment. They kind of sound like they should mean the same thing. In fact they don't! Negative reinforcer means something is taken away to encourage a behavior. This was an example that my psych teacher would give us if we were confused: if a mouse is part of an experiment that it will be continually shocked until it clicks a button. Once the mouse clicks the button the shock is TAKEN AWAY, therefore being negative reinforcement. Punishment is when something is done to try and stop a behavior

Hope this helped and made sense!
