ludovico technique
A fictional behavioral correction treatment from Anthony Burgess' A Clockwork Orange. The participant is restrained, injected with a nausea-inducing compound, and has their eyes forced open; an assistant applies eye drops to keep them from drying out. They are then made to watch violent films while feeling ill, with the intent being to condition a feeling of nausea at the sight of violence. The treatment resembles torture more than anything helpful.
The technique was made famous by Stanley Kubrick's adaptation of the novel, which parodies reference.
