有一组研究人员最近在实验室发起一个的实验,情景模拟消费者的日常体验,旨在研究每天工作后的疲劳对于你大脑的决策评估区块有何影响;就是这个区块负责让你为了省钱买一辆自行车而拒绝和朋友一起出去喝啤酒。
“The neural bases of how we make the decision between consuming and saving are somewhat known,” said neuroscientist Bastien Blain, author of the study published in the Proceedings of National Academy of Sciences in June. “For example, to make a decision between an immediate monetary reward, say, $10 now, and a bigger but delayed one, say, $100 in one year, requires the brain to attribute a value to each option. If we temporarily inhibit a particular brain area, people become more likely to choose the immediate reward option.”
“我们做出消费还是储蓄的选择时所仰赖的神经基础已经部分被知晓了,”在今年六月,在美国国家科学院院刊上发表过著作的Bastien Blain说。“举个例子,是要一份立马到手的10美元,还是要一份1年之后到手的100美元?若要做这个决定,你的大脑首先得为两个选项给定一个价值。如果我们暂时抑制大脑的某个特定区域,人们则更倾向于选择立刻拿到现金。
In Blain’s study, people didn’t show ego depletion after 15 minutes of heavy cognitive work, so the team decided to go beyond the usual short time frame used in similar studies and instead mimic a typical workday. The participants who performed the difficult version of the tasks became more impulsive by the end of the day. The group that performed easy versions of the tasks or enjoyed some breaks during the six-hour episode didn’t show increased impulsivity.
