A team of researchers from the United Kingdom and Spain found evidence showing that contrary to popular belief, the face to orgasm is not the same as the face to pain. In their article published in Proceedings of the National Academy of Sciencesresearchers describe their research and discoveries.
It has become common for people to equate the face of people with an orgasm to that of people suffering from severe pain, probably because of the Hollywood interpretation at once. In this new effort, researchers contradict such suggestions with evidence to the contrary.
To find out more about the faces of people experiencing orgasm or intense pain, the researchers created a computer program to imitate a wide variety of non-sexist facial expressions. They started with mathematical models developed for animating faces. They included a set of 42 movements representing different parts of a face. They then asked 80 adults (half man, half woman) to determine if the expressions showed "orgasm", "pain" or something else. They used the results to develop better models and then asked another 104 people to evaluate the simulated facial expressions.
The researchers found a clear distinction between perceptions of pain and pleasure – most volunteers agreed on what was. But there was more to the study. The volunteers had also been divided into two cultural groups: one half Western culture and the other half Asian culture. Both groups saw clear differences between the orgasmic faces and the distressed faces, but they differed markedly in what they considered the face of a person having an orgasm. Those from Western cultures tended to choose wide-eyed expressions with gaping mouths. Asian volunteers, on the other hand, chose smiling faces with tight lips. The researchers suggest that the differences could be explained by fundamental cultural beliefs such as the value given to behavior related to high or low excitation states.
