问题 New research contradicts a common diet tip believed to help people eat less.The popular tip follows that serving food on a smaller plate tricks a person into believing they are eating more than when served the same amount on a larger plate.However,a new study published in Appetite suggests that when people are hungry,plate sizes don't matter--they are more likely to dish up the same amount of food regardless of how it's served.The long-held belief takes after the Delboeuf illusion,an optical illusion on how people perceive size.In the experiment,two identical circles are placed near each other,one of which is surrounded by another circle.The surrounded circle seems larger than the other.When it comes to dieting,previous research suggests people perceive food proportions differently depending on whether it is served on a larger or smaller plate.If you're looking to eat less,serving food on a smaller plate was thought to trick the eater's mind into believing they are eating more,allowing them to consume less.However,other research has recently begun to call this belief into question."Plate size doesn't matter as much as we think it does,"said Dr Tzvi Ganel in a statement."Even if you're hungry and haven't eaten,or are trying to cut back on portions,a serving looks similar whether it fills a smaller plate or is surrounded by empty space on a large one."Researchers gave study participants photos of pizza placed on large and small trays to one group who hadn't eaten for three hours and to another group of people who had eaten recently.Those who were hungry were better equipped to judge proportions,but that's where the ability to accurately perceive size ends.Both groups were then asked to compare black circles and hubcaps placed in differently sized circles--a task they were equally bad at.As it turns out,hunger stimulates a human response strong enough to resist being fooled by an optical illusion,reducing biases for food but not other stimuli.People who aren't hungry,though,are less likely to identify foodproportions correctly."Over the last decade,restaurants and other food businesses have been using progressively smaller dishes to the perceptual bias that it will reduce food consumption,"said Ganel."This study debunks that notion.When people are hungry,especially when dieting,they are less likely to be fooled by the plate size,more likely to realize they are eating less and more prone to overeating later."According to the passage,the TRUE statement below is________查看材料A.during the pizza-photo test,both groups could identify the food size correctlyB.hungry people are less easily cheated by an optical illusion,and this conclusion applies to all?objectsC.the reason why restaurants use small dishes is that it can save moneyD.the Delboeuf illusion was applied to dieting
选项 A.during the pizza-photo test,both groups could identify the food size correctly
B.hungry people are less easily cheated by an optical illusion,and this conclusion applies to all?objects
C.the reason why restaurants use small dishes is that it can save money
D.the Delboeuf illusion was applied to dieting
答案 D
解析 细节题：根据第四段中的“hungry stimulates a human response strong enough to resist being fooled by an optical illusion，reducing biases for food but not other stimuli．People who aren’t hungry，though，are less likely to identify food proportions correctly”可知，在该实验中，饥饿的一组能更精确地感知大小，而这种优势只对食物有效，所以A、B两项错误：根据最后一段中的“restaurants and other food businesses have been using progressively smaller dishes to the perceptual bias that it will reduce food consumption”可知，餐馆和其他食品企业用小盘子是为了降低食物消耗量，C项“餐馆用小盘子是为了省钱”原文未提到。根据第一段以及第二段中的“The lon9．held belief takes after the Delboeufillusion…When it comes to dieting…”可知，德勃夫大小错觉一度让人们认为用较小的盘子吃饭可以减少进食量，即德勃夫大小错觉曾应用于节食领域。故本题选D。
