Some people claim they “never forget a face”. But what does that saying mean? Is there really no limit to the number of faces a person can remember? A new study at the University of York in England has found that, on average, people can remember as many as 5,000 faces.

The study is the first time that scientists have been able to put a number to the abilities of humans to recognize faces. The research team tested people on how many faces they could remember from their personal lives and in the media. They also tested them to see how many famous faces they recognized. Rob Jenkins works in the psychology department at the University of York. He said the researchers’ study centered on the number of faces people actually know. He said the researchers were not able to discover whether there is a limit on how many faces the brain can handle.

In the study, people spent one hour writing down as many faces from their personal lives as possible. At first, they found it easy to come up with many faces. But by the end of the hour, they found it harder to think of new ones. Their change in speed let the researchers estimate when they would have run out of faces completely.

The results showed that these people knew between 1,000 and 10,000 faces. Jenkins explained that some people may have a natural ability for remembering faces. “There are differences in how much attention people pay to faces and how well they process the information,” he said. Jenkins also said it could be because of different social environments. Some people may have grown up in more populated places. Therefore, they may have had more social contact throughout their lives.

The people in the study included 25 men and women between 18 and 61 years old. Researchers think age may be an interesting area for further research. “It would be interesting to see whether there is a peak age for the number of faces we know”, Jenkins said. He said it is possible that we gather more faces throughout our lifetime. But, he added, there also may he an age at which we start to find it harder to remember all of those faces.

The study suggests our facial recognition abilities enable us to deal with the many different faces we see on the screens, as well as those we know, like family and friends. Today, facial recognition technology is used in many ways, including by law enforcement agencies to prevent crime and violence. Governments use it to keep secret areas secure and, in extreme cases, control populations. Even Facebook uses facial recognition. For example, when you “tag” or name a friend, Facebook technology may recognize the person’s face from a different picture you had shared before.

1The study at the University of York centers on ________.

A.how different people’s faces are

A.Remembering faces is not a natural ability for people.

B.People should gather more faces throughout their lifetime.

C.There is an age at which people can no longer know more faces.

D.People from a place with a large population may know more faces.

A.To present people’s abilities to recognize faces.

B.To tell us how facial recognition helps humans.

【題目】 It's common knowledge that the woman in Leonardo da Vinci's most famous painting seems to look back at observers (觀察者), following them with her eyes no matter where they stand in the room. But this common knowledge turns out wrong.

A new study finds that the woman in the painting is actually looking out at an angle (角度) that's 15.4 degrees off to the observer's right-well outside of the range that people normally believe when they think someone is looking right at them. In other words, said the study author, Horstmann, "She's not looking at you." This is somewhat ironic, because the entire phenomenon of a person's gaze (凝視) in a photograph or painting seeming to follow the viewer is called the "Mona Lisa effect (效應(yīng))". That effect is absolutely real, Horstmann said. If a person is illustrated or photographed looking straight ahead, even people viewing the portrait from an angle will feel they are being looked at. As long as the angle of the person's gaze is no more than about 5 degrees off to either side, the Mona Lisa effect occurs.

This is important for human interaction with on screen characters. If you want someone off to the right side of a room to feel that a person on-screen is looking at him or her, you don't cut the gaze of the character to that side-surprisingly, doing so would make an observer feel like the character isn't looking at anyone in the room at all. Instead, you keep the gaze straight ahead.

Horstmann and his co-author were studying this effect for its application in the creation of artificial-intelligence avatars (虛擬頭像) when Horstmann took a long look at the "Mona Lisa" and realized she wasn't looking at him.

To make sure it wasn't just him, the researchers asked 24 people to view images of the "Mona Lisa" on a computer screen. They set a ruler between the viewer and the screen and asked the participants to note which number on the ruler intersected (橫切) Mona Lisa's gaze. To calculate (估測) the angle of Mona Lisa's gaze as she looked at the viewer, they moved the ruler farther from or closer to the screen during the study. Consistently, the researchers found, participants judged that the woman in the "Mona Lisa" portrait was not looking straight at them, but slightly off to their right.

So why do people repeat the belief that her eyes seem to follow the viewer? Horstmann isn't sure. It's possible, he said, that people have the desire to be looked at, so they think the woman is looking straight at them. Or maybe the people who first created the term "Mona Lisa effect" just thought it was a cool name.

1It is generally believed that the woman in the painting "Mona Lisa"

A.attracts the viewers to look backB.looks at the viewers wherever they stand

C.fixes her eyes on the back of the viewersD.seems mysterious because of her eyes

2The purpose of the experiment involving 24 people was to _________.

A.calculate the angle of Mona Lisa's gazeB.create artificial-intelligence avatars

C.make sure Horstmann's belief is rightD.explain how the Mona Lisa effect can be applied

3What gaze range in a painting will cause the Mona Lisa effect?

A.B.

C.D.

4What can we learn from the passage?

A.Horstmann thinks it's cool to create the term "Mona Lisa effect".

B.The Mona Lisa effect contributes to the creation of artificial intelligence.

C.The position of the ruler in the experiment will influence the viewers' judgement.

D.Feeling being gazed at by Mona Lisa may be caused by the desire for attention.
