"Gay" and "heterosexual" tendencies are written on the face of

A new study found, perhaps not take a second, people will be able to determine through a simple and accurate glimpse of a person's sexual orientation. The findings built on top of a mature theory that subconscious thought to determine human behavior can produce more guidance, which is that people have not thought of before.

Human beings are very good at making quick judgments of others. In the psychologist NaliniAmbady and RobertRosenthal in 1994 completed a landmark study, subjects watched a two-minute video lectures, Professor teaching ability after the conclusion drawn after the end of the semester with the students to write the relevant evaluation actually strikingly similar. The result, psychologists began to think, people in a hurry one can also find out what.

Are now employed in the United States, Massachusetts, Tufts University, Medford city, Ambady and colleagues NicholasRule people became interested in sexual orientation. Subjects showed them to 90 men (including gay and heterosexual men) and women's facial photographs, the time interval from 33 milliseconds to 10 seconds range. The results showed that when the time interval of 100 milliseconds or more, the subjects were able to correctly determine the chances of these people's sexual orientation close to 70%. However, in a relatively short period of time, these volunteers are not easy to make the right judgments. At the same time, when the time interval of more than 100 milliseconds, their accuracy would not be greatly improved. The researchers in the forthcoming publication of "Journal of Experimental Social Psychology," reported the research results. Ambady, said: "Even more interesting is the increase in exposure time does not change the final judge the outcome."

Evans Pass, Illinois Northwestern University psychologist PaulEastwick stressed that romantic attraction is really possible in such a short period of time worked. He said: "If people can quickly to others, gender-related characteristics of an accurate judgments, then you stop and think carefully about how we assess the millisecond time another person's romantic potential."

斯特瑞尔斯City University of Connecticut psychologist DavidKenny that the results of this study proved that the brain has a quick extraordinary ability to make accurate judgments. However, he pointed out that for certain faces of the judicious rate is always lower than 50%, this may be because they face difficult to readResult
