"Dastani’s emotional functions have been derived from a psychological model known as the OCC model, devised in 1988 by a trio of psychologists: Andrew Ortony and Allan Collins, of Northwestern University, and Gerald Clore, of the University of Virginia. ‘Different psychologists have come up with different sets of emotions,’ says Dastani. But his group decided to use this particular model because it specified emotions in terms of objects, actions, and events.”"
