Study more than triples the number of facial expressions researchers can use to track the origins of emotions in the brain

COLUMBUS, Ohio—Researchers at The Ohio State University have found a way for computers to recognize 21 distinct facial expressions—even expressions for complex or seemingly contradictory emotions such as “happily disgusted” or “sadly angry.”

In the current issue of the Proceedings of the National Academy of Sciences, they report that they were able to more than triple the number of documented facial expressions that researchers can now use for cognitive analysis. (more…)

Research using new technology shows that our ability to imitate facial expressions depends on learning that occurs through visual feedback.

Studies of the chameleon effect confirm what salespeople, tricksters, and Lotharios have long known: Imitating another person’s postures and expressions is an important social lubricant.

But how do we learn to imitate with any accuracy when we can’t see our own facial expressions and we can’t feel the facial expressions of others? (more…)

Why are the faces of primates so dramatically different from one another?

UCLA biologists working as “evolutionary detectives” studied the faces of 129 adult male primates from Central and South America, and they offer some answers in research published today, Jan. 11, in the early online edition of the journal Proceedings of the Royal Society B. The faces they studied evolved over at least 24 million years, they report. (more…)
