Professor Jack Vernon of Princeton University carried out a large number of sensory deprivation experiments and, in his book Inside the Black Room , suggests a scenario for creating attitude change which incorporates findings from sensory deprivation research, conditioning, cognitive dissonance, dependence, obedience to authority and participation as means of attitude change. This is the scene he proposed.
He notes first that both in the softening-up process preceding brainwashing and in the sensory deprivation condition, a confined person will experience such dreadful monotony and boredom that he will be grateful for absolutely any novelty to distract him. This could be taken advantage of, says Vernon, if the aim is to instil a particular belief in a person. He suggests, for the experiment's sake, that someone who is a strong Protestant, although he doesn't know much about Protestantism, is to be converted to Islam, about which he knows very little either but he is prejudiced enough to hate Muslims. To convert him, says Vernon, the best procedure would be to leave him in sensory deprivation conditions for up to four days, to bring him to the point where he is desperate for stimulus of any kind. Then Vernon would introduce, without any explanation, two switches into the cubicle.
The 'prisoner' would soon find that if he pressed button A, he heard a speech favouring Protestantism. If he pressed button B, he got a speech favouring Islam. But the difference was that button A always produced the same speech on Protestantism whereas button B released an endless variety of speeches on Islam, all delivered by different voices. Desire for novelty would lead the prisoner to start selecting button B over button A.
'We have caused this individual by his own choice to listen to our propaganda. If we can get him to listen, we can get him to believe by making our propaganda clever enough, says Vernon, and it isn't all supposition. An experiment at McGill University in Canada found that subjects did indeed listen more often to varied unfavoured items than the same favoured item when in a condition of having no other choice.
But Vernon carries on. Even if the prisoner does insist on using button A, it still works against him, he says, because repetition can weaken meaning. He recalls the familiar experience of repeating a word over and over and finding that it suddenly becomes strange, as though it is a new word. Its meaning seems to have weakened.
