问题 When Our Eyes Serve Our Stomach
Our senses aren’t just delivehng a strict view of what’s going on in the world ; they are affected by what’s going on in our heads. A new study finds that hungry people see food-related words more clearly than people who’vejust eaten.
Psychologists have known for decades that what’s going on inside our heads affects our senses. For example，poorer children think coins are larger than they are，and hungry people think pictures of food are brighter. R6mi Radel of University of Nice Sophia-Antipolis， France, wanted to investigate how this happens. Does it happen right away as the brain receives signals from the eyes or a little later as the brain’s high-level thinking processes get involved?
Radei recruited 42 students with a normal body mass （质量）index. On the day of his or her test，each student was told to arrive at the lab at noon after three or four hours of not eating. Then they were told there was a delay. Some were told to come back in 10
minutes; others were given an hour to get lunch first.So half the students were hungry when they did the experiment and the other half has just eaten.
For the experiment，the participant looked at a computer screen. One by one，80 words flashed on the screen for about 1/300th of a second each. They flashed at so small a size that the students could only consciously perceive.A quarter of the words were food-related- After each word ， each person was asked how bright the word was and asked to choose which of two words they’d seen_a food related word like cake or a neutral（中性的）word like boat. Each word appeared too briefly for the participant to really read it.
Hungry people saw the food-related words as brighter and were better at identifying food-related words. Because the word appeared too quickly for them to be reliably seen,this means that the difference is in perception, not in thinking processes，Radel says.
"This is something great to me:Humans can Really perceive what they need or what they strive （奋斗）for. From the experiment I know that our brain can really be at the disposal（处理）of our motives （动机）and needs," Radel says.

It can be leamt from what Radel says that
选项 A. humans’ thinking processes are independent of their senses.
B. humans can perceive what they need without deep thinking processes.
C. an experiment with hungry and non-hungry participants is not reliable.
D. 42 participants are too small a number for a serious investigation.
答案B
解析第五段第二句话提到"Because the word appeared too quickly for them to be reliably seen，this means that the difference is in perception，not in thinking processes”，以及第六段第二句话提到"Humans can really perceive what they need or what they strive for”，由此可以看出人类可以不经过深入思考就能感知到他们的需求，所以答案是B。
