At a hospital I work in (as a new psychiatry trainee), some admitted patients - especially those with conversion disorder - are made by psychologists to:
- Stop meeting their friends or family
- Spend the entire day in isolation on their beds
- Only eat simple (but not aversive) food such as bread with milk.
This treatment lasts for weeks. They call it "extinction therapy". However, in attempts of finding scientific evidence relating to this practice, I looked it up online and couldn't find any references to "extinction therapy".
My question is: Is the above psychological management a known and named concept? If so, what is it called?
