Wall Street Journal: Smiles Hide Many Messages—Some Unfriendly

“Smile while your heart is breaking, put on a happy face, say cheese. We’re so used to smiling on demand that to do otherwise can seem antisocial. Even going through the motions of a smile, scientists have found, can make us feel happy.” The Wall Street Journal interviewed our own Jared Martin, the first author of a recent paper demonstrating the distinct effects of smiles of reward, affiliation, and dominance on recipients' stress levels.

Nature Scientific Reports: Functionally distinct smiles elicit different physiological responses in an evaluative context

When people are being evaluated, their whole body responds. Verbal feedback causes robust activation in the hypothalamic-pituitary-adrenal (HPA) axis. What about nonverbal evaluative feedback? Recent discoveries about the social functions of facial expression have documented three morphologically distinct smiles, which serve the functions of reinforcement, social smoothing, and social challenge. Jared Martin is the first author on the latest paper from our lab, published in Nature Scientific Reports.

Hot off the press in Psych Science: social functional smiles

Our latest empirical article uses a data-driven approach to build prototypical models of smiles that accomplish distinct social tasks: rewarding the self and others (reward), conveying non-threat and maintaining bonds (affiliation), and negotiating social status (dominance). Magdalena Rychlowska, the first author, is a former graduate student of the Niedenthal Emotions Lab and is currently a postdoctoral fellow at Queen's University Belfast, working with Will Curran and Gary McKeown. Co-authors Rachael Jack, Philippe Schyns, and Oliver Garrod (University of Glasgow) contributed their reverse-correlation approach for synthesizing models of facial expressions using perceiver responses.
