Just as parents socially reward children, children socially reward us as parents: by doing what is asked of them having a generally cheerful disposition, smiling and laughing, acting excited and happy when they see us, showing affection, and imitating our behavior – in short, by making us feel needed and loved.

As children grow into the teenage years there is often a marked change in their world of social rewards. They have many friends at school, an entire social structure outside the social rewards more than those at home. Parents often wonder what happened. They feel that their children no longer consider them so important. There may he some truth in this but if parents give a lot of social rewards (even to teenagers), it is reasonable to expect that teenagers will reciprocate. Teenagers can socially reward parents by showing affection (although perhaps toned-down), having a sense of humour, talking about their lives, showing interest in what their parents are doing, and not treating them as if they were horribly old-fashioned.

Finally, this principle applies not only between parents and children but is true with any two individuals, brother and sister, husband and wife, employer and employee, or friends.
