Published on Journal of Nonverbal Behavior.

Though I did not read this paper (UCSD does not purchase the online version). This article received pretty good media coverage (Telegraph).

BBC created a website for visitors to test their ability in discerning true versus fake smiles in 20 videos. The test is based on Paul Ekman’s research.
