Apter’s Reversal Theory

This theory describes how a change in the intensity of stimulus can alter how a clinician feels and performs in the working environment.

For example, a junior doctor repeatedly asking a nurse the same questions about a procedure can change the nurse's reaction from a cooperative emotion to one of irritation and hostility.

If the nurse is filled with unpleasant feelings about the encounter she is likely to try and shorten the encounter or avoid working with that junior doctor in future.
