To function well in the world, people need a good sense of where their body is in space and how it’s postured. This "position sense" helps us coordinate high-fives, boot a soccer ball or pick up the remote. But that doesn’t seem to mean that our brains have an accurate sense of our body’s precise proportions. A new study found that people tend to have rather inaccurate mental models of their own hands.
When asked to estimate where the fingertips and finger joints of their hidden hands were, study volunteers were way off. But they were all incorrect in the same directions, guessing that their hands were both shorter and wider than they actually were. The findings come from a study led by Matthew Longo of the Institute of Cognitive Neuroscience at University College London. "Our results show dramatic distortions of hand shape, which were highly consistent across participants," Longo said in a prepared statement.
He and his co-author, Patrick Haggard, had subjects place their left hand on a platform (using different orientations in different groups), which was then covered with a board to obscure the hand. The subjects were asked to use their free right hand point with a stick to the location of each finger joint and fingertip of their left hand. The process was filmed and compared to before and after pictures of the hand. On average, the volunteers judged their hands to be 27.9 percent shorter and 69 percent wider than they were measure to be. Underestimation of each finger length, from the thumb to the little finger, increased by about 7 percent in each finger, rendering the little finger quite a bit littler than it really was.
This trend "mirrors similar grades of decreasing sensory acuteness," the authors pointed out, and the results seem to back up models of the human body constructed from the amount of sensory cortex dedicated to various body parts. In these models the hands and face are disproportionately large in comparison to most of the body. But Longo and Haggard are still not sure why the brain has such a distorted perception of our hand proportions.
Longo speculated that these disproportions might occur in other parts of the body as well. "These findings may well be relevant to psychiatric conditions involving body image such as anorexia nervosa, as there may be a general bias toward perceiving the body to be wider than it is," Longo said. "Our healthy participants had a basically accurate visual image of their own body, but the brain’s model of the hand underling position sense was highly distorted. This distorted perception could come to dominate in some people, leading to distortions of body image."
Longo would most likely agree that ________.
选项
A、healthy people have a basic idea of their body
B、some people have imprecise sense of body proportions
C、distorted senses of hand are dominant among all people
D、people only have inaccurate sense of hand proportions
答案
B
解析
根据题干中的Longo以及选项里出现的healthy people,dominant等词可定位到最后一段。该段便讲到,人们对手的比例感知错误也会发生在身体的其他部位,B项所说的:imprecise sense of body proportions与该句意思吻合,而该段最后一句也提到一些人可能由于受到大脑对于手失真感觉的支配作用对身体也会有失真感。结合这两句,可以确定答案为B项。A项的语义范围非常大,该段第三句只是谈到健康的受试者基本上有准确的视觉身体印象,但是否对自己的身体有基本的概念,隆戈的话语中并没有谈及,故A项可排除。C项中的among all people错误,文中第四句说的是some people,C项扩大了对象的范围。D项也错误,因为该段第一句已指出这样的比例错误也会发生在身体的其他部位。
