0.66more forthe itemthey hadbeen madeto want,and anaverage of$

0.66美元，或是为类似的快餐食品平均额外付出

0.26美元而对于那些相似度较低因此更加健康的食物，例如格兰诺拉燕麦卷或椒盐脆饼干，受试者却不愿付出这么多钱，这表明他们的渴望与通常意义上的饥饿有所不同In asecond experiment,the researchersrepeated theprocess with45people.This time,however,individuals couldopt topayforone,two,three,five oreight“units ofwhatever theydbeen madeto crave.This time,the researchersfound thatpeople werealso willingtopaydisproportionately morefor largerquantities ofwhatever foodthey desired.在第二项实验中，研究人员对45名受试者重复了上述过程不过这一次，每个人可以花钱购买他们渴望的任意多项食物这一次，研究人员发现，人们愿意为喜欢的大量食物付出不成比例的更多价钱Taken together,the resultsdemonstrate thepower ofcravings—whether forfood orsomething else.两项试验的结果表明了渴望的力量一一无论是对食物还是对其他事物“Even ifpeople striveto eathealthier orendorse drug-free lifestyles/the researcherswrite inthe paper,craving couldovershadow thevalue ofhealth byboosting thevalue ofunhealthy foodsor drugs/研究人员在论文中写道〃即使人们努力健康饮食，避免吸毒，但他们的渴望也会提高不健康食品或毒品的价值，而让健康的生活方式较之黯然失色〃On thebright side,however;theresearchersestimated theeffects ofsubjects cravingswould dissipatewithin twohours,and potentiallyless timeif thisgood isnot available,or whena personengages inself-regulation/If youreable towait itout,then,you maybe ableto resistthe lureof junkfood.不过，好的一面在于，研究人员估计这种渴望会在两个小时内消散，如果〃满足渴望的条件不足，或某人自制力很强〃，消散的速度会更快因此，如果你能忍一会，或许就可以抵挡垃圾食品的诱惑。
