вЂњOverall, I would describe Hillary as the Happy Warrior,вЂќ Bucy said. However, both candidates showed they have pretty good вЂњpoker faces,вЂќ Ketelaar said - citing ClintonвЂ™s reaction when Trump alluded to Bill ClintonвЂ™s infidelity, as well as TrumpвЂ™s reaction to ClintonвЂ™s speculation on his tax returns.Д®rik Bucy, the Marshall and Sharleen Formby Regents Professor of Strategic Communication at Texas Tech University, measured votersвЂ™ real-time responses to the candidatesвЂ™ nonverbal behavior and tone of voice. Ketelaar also observed a few indications of contempt - which, in Clinton, typically was expressed through a forced smile, while Trump nervously took drinks of water. But I thought Clinton had a slight advantage, in terms of positive emotions such as smiling.вЂќ вЂњThere was no big loser, in terms of facial displays. вЂњI donвЂ™t feel like the debate was won or lost on the basis of facial expressions,вЂќ he said. Ketelaar didnвЂ™t observe anything in the candidatesвЂ™ facial expressions that seemed to him to be determinative. вЂњShe smiled a little bit more than we normally see her smile.вЂќ вЂњWe saw more positive emotion in Hillary ClintonвЂ™s face than weвЂ™ve seen before,вЂќ he said. ThatвЂ™s a crude simplification, but it tends to be the case.вЂќДЄt Monday nightвЂ™s debate, neither Hillary Clinton nor Donald Trump displayed a lot of negative emotion in their facial expressions, Ketelaar said. вЂњAnd we tend to assume a person is more trustworthy the more positive emotion we see. вЂњAnyone watching the debate will form judgments of truthfulness largely based upon whether theyвЂ™re seeing lots of negative emotion - we tend to assume that person is untrustworthy, the more negative emotion we see,вЂќ Ketelaar said. Ketelaar was trained by Paul Ekman, one of the leading experts on microexpressions and a chief consultant on the Fox show, вЂњLie to Me.вЂќ Ketelaar is an expert in the science of human emotions and in facial expressions and microexpressions. Tim Ketelaar, an associate professor of psychology at New Mexico State University, was part of the four-person panel. LAS CRUCES - The morning after the first presidential debate, a group of psychologists, cognitive scientists and communications experts got together on the internet to discuss their observations of the candidates.
