课时作业(五) Unit 5 Part A Topic Talk .阅读理解 A Will your happiness differ if you are doing a kind action without any expectation of rewards or with an expectation of rewards? A study by University of Sussex, headed by Dr. Daniel Campbell Meikeljohn, tried to answer that question. He and his partners analyzed over 1,000 brain scans from other studies related to reactions to making a decision based on kindness. They split the studies based on who was making a decision for altruistic (无私的) reasons and who was making a decision due to the expectation of an obvious reward. The results were interesting. In both instances, the reward center of the brain lit up on the MRI scans (磁共振成像扫描). Yet, for those who made their decision without any rewards, other areas of the brain lit up as well. Specifically, it lit up the subgenual anterior cingulate cortex (前扣带皮层区域), which scientists believe plays a role in emotional regulation. Also, it might aid in maintaining excitement related to an event that creates a positive emotional state. In one study about the subgenual anterior cingulate cortex, it is believed that this brain region could be related to depression if it isn't developed properly or is dysfunctional. The fact that this part of the brain lights up during acts of generosity and caring without expectation of rewards shows that the altruistic individuals are getting more sustainable pleasure than those motivated by rewards. It also could aid in explaining how it helps depressive individuals feel happier after doing a kind deed. We live in a society, and no man is a lonely island. We all need each other. For those who genuinely desire to help others regardless of repayment, maintaining a balance of helping others and yourself is very important. It is healthy and necessary to be kind to yourself, as well as to others. 1.Why did the author think the results interesting? A.There are no differences as to the lit up area of the brain.
