But first, let's go back to the 'limited supply' theory. An experiment back in the 1990s formed the popular theory in psychology that your willpower is limited. The experiment is known as the Chocolate-and-Radish Experiment. Researchers put 67 study subjects in a room that smelled of freshly baked chocolate cookies. Sounds good, right? Wrong._______________________________但先回头再看看意志力有限的理论. 在20世纪90年代一项实验中,形成了著名的心理学理论称意志力是有限的.该实验被称作是"巧克力和萝卜实验". 研究人员将67个研究对象放置于充满新鲜出炉巧克力曲奇味道的屋中. 听起来很棒,对吧?不是的._____________________________
