The latest study on face blindness
有关脸盲症的最新研究
comes from the Prosopagnosia Research Centers at Dartmouth College in the United States.
来自美国达特茅斯学院的面容失认症研究中心。
Bradley Duchaine is a professor of psychological and brain sciences at Dartmouth College.
布兰得利迪谢纳是达特茅斯学院的心理学和脑科学教授。
Duchaine says that the research showed "neural abnormalities in many 【people with】 DP
患有某种疾病/有某种需要的人
Eg: We should provide assistance to people with disabilities.
迪谢纳说,这项研究说明"在很多患有DP的人中,
are more widespread than previous studies have suggested."
神经异常比以前的研究所显示得更普遍。
Duchaine says that studying face blindness
迪谢纳说,研究脸盲症
may help researchers understand how the brain works.
可以帮助研究人员理解大脑是如何工作的。
For example, Duchanie says his team wanted to see
例如,迪谢纳说他的团队想知道，
If the brain recognize people and things in the same way.
大脑识别人和识别物的方式是否相同。
So, the researchers tested how well people with face blindness
因此,研究人员测试了脸盲症患者
could recognize common objects, such as cars.

They found that people with DP may not have been able to remember faces,

However, he said it could lead to 【a deeper understandingof】
