问题     According to new research, imagining eating a specific food reduces your interest in that food, so you eat less of it. This reaction to repeated exposure to food is called habituation (习惯化) ,and it’s well known to occur while eating. "A tenth bite of chocolate, for example, is desired less than the first bite," the study authors note.
    But the new research is the first to show that habituation can occur solely via the power of the mind. " A lot of people who diet try to avoid thinking about stimuli they desire. This research suggests that may not be the best strategy," said study leader Carey Morewedge, a psychologist at Carnegie Mellon University in Pittsburgh.
    " If you just think about the food itself—how it tastes, smells, and looks—that will increase your appetite," Morewedge said. "This research suggests that it might be better,actually,to force yourself to repeatedly think about tasting, swallowing, and chewing the food you desire to reduce your cravings. " What’s more,the technique works with only the food you’ve imagined,he added. For instance,imagining eating chocolate wouldn’t prevent you from gorging on cheese.
    Morewedge and colleagues conducted five experiments, all of which revealed that people who repeatedly imagined eating chocolate or cheese would eat less of that food than people who pictured eating the food fewer times,eating a different food,or not eating at all. In one experiment,for instance,51 subjects were divided into 3 groups. One group was asked to imagine inserting 30 quarters into a laundry machine—which requires the same motor skills as eating the chocolate M    The study is part of a new area of research looking into the triggers that make us overeat, Morewedge noted. Physical, digestive cues—that full-belly feeling—are only parts of what tells us that we’re finished a meal. Eecent research suggests that psychological factors,such as habituation or the size of a plate, also influence how much a person eats. Such experiments are important as obesity rates climb—in the United States, for instance, nearly 30 percent of adults were obese in 2009, according to the U. S. Centers for Disease Control and Prevention The new study, Morewedge said, may lead to new behavioral techniques for people looking to control overeating or other addictive behaviors such as smoking.
Different to the previous researches on habituation, the new study tends to______.
选项 A、show that habituation can occur only under the psychological factors
B、suggest people resist the thinking of the stimuli they long for
C、reveal people’s interest in the food they desire
D、prevent people from eating less while dieting
答案A
解析 推理判断题。本题考查新的研究与之前关于习惯化行为研究的不同之处。第一段提出了新的研究结论，引出“习惯化”这一概念。定位句指出新研究第一次指出习惯化仅仅通过对大脑影响来实现。故答案为A)。B)“建议人们不要去想那些诱惑自己的食物刺激”，与此项研究结果相反，排除；C)“揭示了人们对渴望的食物感兴趣”，文中未涉及，故排除；D)“阻止别人为了减肥而节食”与新研究要解决的问题无关，故排除。
