问题     A research led by the University of Sydney has found that people often think other people are staring at them even when they aren’t. When in doubt, the human brain is more likely to tell its owner that he’s under the gaze of another person.
    "Gaze perception—the ability to tell what a person is looking at—is a social cue that people often take for granted," says Professor Colin Clifford from the University’s School of Psychology.
    To tell if they’re under someone’s gaze, people look at the position of the other person’s eyes and the direction of their heads. These visual cues are then sent to the brain where there are specific areas that compute this information.
    However, the brain doesn’t just passively receive information from the eyes. The study shows that when people have limited visual cues, such as in dark conditions or when the other person is wearing sunglasses, the brain takes over with what it "knows".
    The researchers created images of faces and asked people to observe where the faces were looking. "We made it difficult for the observers to see where the eyes were pointed so they would have to rely on their prior knowledge to judge the faces’ direction of gaze," Professor Clifford explains. "It turns out that we’re likely to believe that others are staring at us, especially when we’re uncertain."
    "There are several speculations to why humans have this bias," Professor Clifford says. "Direct gaze can signal dominance or a threat, and if you perceive something as a threat, you would not want to miss it. So assuming that the other person is looking at you may simply be a safer strategy. Also, direct gaze is often a social cue that the other person wants to communicate with us, so it’s a signal for an upcoming interaction."
    "It’s important that we find out whether it’s innate or learned—and how this might affect people with certain mental conditions," Professor Clifford says.
    Research has shown, for example, that people who have autism (孤独症) are less able to tell whether someone is looking at them. People with social anxiety, on the other hand, have a higher tendency to think that they are under the stare of others.
    "So if it is a learned behaviour, we could help them practice this task—one possibility is letting them observe a lot of faces with different eyes and head directions, and giving them feedback on whether their observations are accurate." [br] What does Professor Clifford say about direct gaze?
选项 A、It can signal dominance and bias.
B、It may make people feel threatened.
C、People tend to avoid direct gaze.
D、People may use it as a safe strategy.
答案 B
解析 细节题。根据题干中的Professor Clifford say about direct gaze定位到原文第六段。第六段第二句中引用克利福德教授的话指出，直视会发出一种支配或威胁的信号。如果你察觉到了某种潜在威胁，肯定不会忽视它。因此假想别人正在注视自己不过是一种更安全的策略而已。因而B项表述符合原文，故选B。
