Which technique of self-control involves rewarding behaviors with pleasant outcomes?

Self-reinforcement

A number of psychological techniques of self-control have also been suggested. Observation of own behaviour is one of them. This provides us with necessary information that may be used to change, modify, or strengthen certain aspects of self. Self-instruction is another important technique. We often instruct ourselves to do something and behave the way we want to. Such instructions are quite effective in self-regulation. Self-reinforcement is the third technique. This involves rewarding behaviours that have pleasant outcomes. For example, you may go to see a movie with friends, if you have done well in an examination.
