Have you ever had the strange feeling that you were being watched? You turned around and ,sure enough, someone was looking right at you!

Parapsychologists(灵学家)say that humans have a natural ability to sense when someone is looking at them. To research whether such a “sixth sense”really exists, Robert Baker, a psychologist(心理学家)at the University of Kentucky, performed two experiments.

In the first one, Baker sat behind unknowing people in public places and stared at the backs of their heads for 5 to 15 minutes. The subjects(受试者)were eating, drinking, readingstudying, watching TV, or working at a computer. Baker made sure that the people could not tell that he was sitting behind them during those periods. Later, when he questioned the subjects, almost  all of them said they had no sense that someone was staring at them.

For the second experiment, Baker told the subjects that they would be stared at from time to time from behind a two way mirror in a laboratory setting. The people had to write down when they felt they were being stared at and when they weren’t. Baker found that the subjects were no better at telling when they were stared at and when they weren’t .Baker found that the subjects were no better at telling when they were started at than if they had just guessed.

Baker concludes that people do not have the ability to sense when they’re being stared at.If people doubt the outcome of his two experiments, said Baker, “I suggest they repeat the experiments and see for themselves.”

Local police will begin pulling over drivers and cyclists tomorrow so they can fill out a survey to help the city better understand and improve its traffic situation.

The survey, which will run from tomorrow until the end of the year, is the biggest of its kind in the city's history. It will be used to gather information about traffic patterns to help future urban planning, particularly for the World Expo in 2010.

“The survey is to determine the city's daily and weekly traffic situations,” Zhang Yan, a senior engineer at the Shanghai Urban Planning and Design Research Institute, said yesterday. This is the third time the city has conducted a large-scale traffic survey. The other two surveys were conducted in 1986 and 1995.

Officials will send questionnaires to pedestrians and drivers, record traffic jams in major areas, and analyze the information from electronic traffic signs.

The Road Administrative Office will also survey traffic outside the Outer Ring Road, paying particular attention to vehicles entering or exiting the city.

“With more vehicles from neighboring provinces, we have to find it out how many, when and for what purposes those vehicles are coming to the city,” said Dong Hui, a spokeswoman for the Road Administrative Office.

Officials from her office will stop about half of the vehicles passing by 53 major venues (场所) tomorrow and ask drivers to fill out questionnaires about where they are coming from, where they are headed and whether their trip is for private or business purposes.
