Which of the following is true of spontaneous recovery in classical conditioning? Multiple Choice a) It occurs whenever an uncon
ditioned response causes a conditioned response. b) It results in the weakening of the conditioned response. c) It results in the weakening of the unconditioned stimulus. d) It occurs without further conditioning.
The answer is B. It results in the weakening of the conditioned response.
Explanation:
Spontaneous recovery happens when, after a resting period in which the stimulus is no longer presented, the conditioned response that was thought to be extinct reappears. For example, if you train your dog to sit at the sound of a bell and give him a treat when he does, once you stop giving him the treat he will eventually stop sitting when you ring the bell; after a while you ring the bell once more and the dog sits.
Although spontaneous recovery means the conditioned response is not extinct it also results in its weakening, meaning that the response will eventually disappear.
Poor districts or 'slums' in America used to be terrible. Sickness spread easily in these dwellings due to poor filtration of standing water and waste disposal, along with overcrowded living spaces.
