Reversal Theory
Reversal Theory is a distinctive theory of personality, 
motivation and emotion that focuses on the way people change during the course of everyday life. Researched at over 30 Universities worldwide, it has been employed in many different fields of human activity including sport, health, market research and performance at work.
The key insight is the idea that our experience is shaped by a set of alternative ways of seeing the world. According to this theory, people are driven by eight core motivational states - organised into four pairs of opposite states – and are constantly moving through a dynamic pattern of reversals within each pair. Psychological health and effectiveness is maximised when people are able to experience all eight states, and match their state to the demands of the situation.
