Question

Quizplus · Accepted Answer

Experimental extinction occurs when the CS is repeatedly presented without the US, which leads to gradual weakening and eventual disappearance of the conditioned response. Option B (repeated presentations of the US without the CS) is not a method of extinction but rather a procedure called backward conditioning, in which the US is presented before the CS. Option C (severing the US-UR link) may lead to a change in the form of the UR, but it does not necessarily result in extinction of the CR. Option D is not the best choice because option B is incorrect.
