New York—By studying blindfolded college students who move through grass to find a chocolate scented(有…气味的)path by smelling, researchers say they’ ve found evidence of a human smelling ability that scientists thought impossible.
The study shows the human brain compares information it gets from each nostril(鼻孔)to determine where a smell is coming from. And it suggests dogs and mice and some other mammals(哺乳动物)do the same thing, unlike what most scientists have thought.
People compare signals(信号)from each ear to determine the direction of a noise. But most scientists’ idea has been that mammals can’ t do it in the same way for smells, because their nostrils are too close together to get different signals.
" We
debunked
that," said Noam Sobel of the University of California, Berkeley, who reported the new results Sunday with graduate student Jess Porter and others on the Website of the magazine Nature Neuroscience.
The report isn’ t the first to suggest the two-nostril idea. But Sobel and his team have now " opened the doors for full consideration of it," said a researcher familiar with the work.
Most of the paper focuses on what a group of undergraduate psychology students could do in a garden on the Berkeley campus.
One outdoor experiment was designed to see if people could use just their noses to follow a 30-foot-long path of chocolate scent through the grass.
The path was laid out with scented ropes. But the 32 students were blindfolded and equipped with thick gloves to make sure they couldn’ t see or feel it.
Two-thirds of the students succeeded in following the scent. Another experiment found that the volunteers succeeded only one-third of the time with one nostril taped shut.
In Sobel’ s study, the students were asked to______.
选项
A、find the hidden ropes in grass
B、feel their way out of the garden
C、follow the chocolate smell
D、share chocolate bars
答案
C
解析
细节题。题干意为“在Sobel的研究中,学生们被安排做…”由文章倒数第二段“…were blindfolded and equipped with thick gloves…”可知,参加实验的学生眼睛被蒙起来,被要求根据鼻子闻到的气味前行,故选C。
