[Conditioned reflex inhibition therapy for women addicted to sex under the influence of methamphetamine].

If behaviour which has a physiological reward is repeated, a chain of conditioned reflexes is established in the first signal system. When exposed to a signal which is connected to a particular physiological reward, the chain reaction of conditioned reflex begins and controls that behaviour. If one's thought (the second signal system conditioned reflex) tries to stop the behaviour, friction occurs between the two systems.
