(23)Next time you’re craving a bar of chocolate, give in. Your waistline might not thank you for it, but your brain will. Research has revealed that obsessing over a sweet treat is such a drain on the brain that it makes it difficult to concentrate on other tasks. The researchers, from Melbourne’s Flinders University, center on cravings for specific foods and brands. They found that someone experiencing a craving isn’t just hungry, they want to eat a particular brand of biscuits or flavor of ice cream, and nothing else will do. The research team set out to see whether the intensity of these desires affects our ability to concentrate on other things.(24)They found that volunteers whose favorite chocolate bar was unwrapped and within their reach while they sat a series of tests had slower reactions and poorer memories than those who did the same tests in a chocolate-free zone. The researchers believe that when we crave a food we draw a mental picture of it. This picture ties up brain regions needed for other tasks, including math and memorizing and the consequences don’t end there. Writing in the journal Current Directions in Psychological Science, the researchers said, "Although cognitive effects of individual food cravings are likely to be small, in practice even small reductions in cognitive resources have the potential to compromise optimal performance in everyday situations, thereby reducing work efficiency or increasing the likelihood of accidents."(25)But the researchers also believe that filling the brain with competing images, such as visualizing a rainbow, can ease cravings. Researcher Dr. Eva Kemps said, "Engaging in a simple visual task seems to hold real promise as a method for curbing food cravings."

事实细节题。本题问的是这项研究有什么发现。短文在介绍研究项目时提到,研究者选取了几种特定品牌的食物,召集了志愿者,希望能够验证人们对食物的渴求是否会影响其对其他事物的注意力。进行测试时,一组人身旁有唾手可得的巧克力,另一组人身边没有巧克力。结果显示,第一组的人反应要慢一些,记忆力也相对下降了。
