In a study of women undergoing treatment for ovarian cancer,researchers found that,following several chemotherapy sessions,the patients' immune systems were weakened as soon as they entered the hospital-in anticipation of the treatment.What had become a conditioned stimulus in this example,causing an inhibition of cellular activity?

Question

Quizplus · Accepted Answer

The hospital had become a conditioned stimulus because the patients' immune systems started to weaken as soon as they entered the hospital, anticipating the chemotherapy treatment. This is an example of classical conditioning, where a previously neutral stimulus (the hospital) becomes associated with an unconditioned stimulus (chemotherapy) that elicits an unconditioned response (weakening of the immune system). Over time, the neutral stimulus alone can elicit a conditioned response similar to the unconditioned response.
