This will provide you with a basic scope on what intermittent reinforcement is.

It works much greater than typical reinforcement. Now while in psychology this is often used as a way to train a dog, a kid. However, the beasic concept can be applied to push-pull theory.

Intermittent reinforcement is providing the stimulus(in our case a HB) with rewards(compliments etc.). However it is only given some times.

Intermittent reinforcement works much greater than constant reinforcement. So if you're always giving your child a cookie for doing something good, let's give them that cookie only once every five times on a random schedule .

You see what im getting at here, a little "you have beautiful eyes" is good, in moderation.
