Gah,it's late and work tomorrow but will give it a whirl.
Positive reinforcement = something added to a situation that increases relevant behaviour.
So..kid does something,gets praised and he does it again.
Or....you masturabate and orgasm so you do it again (I aim to make examples memorable!!)
Negative reinforcement = somethng taken away from a situation that increases relevant behaviour.
So..you want your kid to clean his teeth b ut every time you get the toothpaste out,he runs away screaming.You put the toothpaste away so of course he is more likely to scream and run away next time.
Or..you put on sunglasses to avoid glare of sun.It works so you do it again next time.
Positive punishment =something added to a situation that decreases relevant behaviour.
So...your kid has his list of chores added to when he behaves badly.
Or...you touch a hot stove with the result that you get burned.You are less likely to do it in future.
Negative punishment=something removed from a situation that decreases relevant behaviour.
So..your kid hits his brother.He is then not allowed to go swimming with you.
Your dh approaches you for sex. You get out of the bed in a huff.
It is really quite difficult to tease it all out.Also,many different reinforcement contingencies working at same time.
I haven't yet read Kohn's book (but will) Essay was only a 500 word personal reflection on a quote fro it.
