The human brain processes male and female voices differently, according to a recent study, which explains why most of us hear female voices more clearly. The study also explains how we form mental images of people based only on the sound of their voices. The findings, published in the journal NeuroImage, might also give insight into why many men tire of hearing women speak. It seems the complexity of female voices requires a lot of brain activity.
    "It is females’ increased use of prosody, or the natural melody of speech, that makes their voices more complex," says author Professor Michael Hunter. Hunter, professor of medicine and biomedical sciences at the University of Sheffield’s Cognition and Neuroimaging Laboratory, says these qualities are not related to pitch, but rather to the vibration and number of sound waves.
    For the study Hunter and his colleagues played recordings of male and female voices to 12 men while they underwent MRI, or magnetic resonance imaging, brain scans. Test subjects assigned a gender to the voices they heard while the scans took place, and were 98 to 99 percent accurate. Researchers monitored the areas of the brain that showed activity during the scans.
    The scientists found that female voices activate the brain’s auditory section. But male voices activated the area at the back of the brain called the mind’s eye, where people compare other individuals and things to themselves. While the researchers only analyzed how a male brain works, they theorized that female voices are always processed in the brain’s auditory region, even when women are listening to other women.
    But Hunter thinks female voices may also activate the mind’s eye in females, since a woman would compare her voice to that of the other female speaker. Since humans process female voices in an area of the brain that’s geared for sound, we tend to hear female voices more clearly. While Hunter believes female voices are complex, he says that once they are interpreted in the auditory part of the brain, they are more fully and readily decoded.

选项 A、Because those women’s voices sound like men
B、Because a woman would compare her voice to that of the other female speakers.
C、He does not explain it clearly in this article.
D、Because the area of the mind’s eye is geared for sound.

答案 B

解析 因果关系的找寻和判断。Hunter为什么认为女性声音也可激活女性脑部的思维之眼呢?根据原文可知since a woman would compare her voice to that of the other female speaker即因为女性会将自己声音与其他女人的声音作比。由此可见,B项内容与原文相符,因此该项为正确答案。
