Greencastle, Ind. — Research conducted at DePauw University by Matthew J. Hertenstein, associate professor of psychology, an alumna, and two of his students is getting worldwide media attention today. "According to scientists it is possible to predict whose marriages will fail by looking at photographs taken decades earlier," begins a story in the London Daily Mail. "Those with the brightest smiles are more than three times as likely to have a strong marriage than those who frown their way through family outings as a child or teenager. Even snaps taken at the age of five yield clues about the path a person's life will take."

The research is published in the new edition of the journal Motivation and Emotion. It was authored by Dr. Hertenstein; Carrie A. Hansel, formerly research coordinator at DePauw's Emotion Lab and 1993 graduate of the University; and 2008 DePauw graduates Alissa M. Butts and Sarah N. Hile, who were the students of the professor.

"Smile intensity predicted whether or not participants divorced at some point in their lives," the researchers write. "The less intensely participants smiled, the more likely they would be divorced later in life."

The text continues, "To make the link, the researchers asked almost 650 adults for pictures taken during their final year of school and rated the brightness of their smiles. The men and women ranged in age between 21 and 87, meaning some of the snaps were 70 years old. The scientists, from DePauw University in Indiana, then asked the volunteers if they had ever been divorced — and matched their answers with the data on their smiles. Those with the weakest smiles were more than three times as likely to have been through a divorce than those who beamed their way through their teenage years," reports the Daily Mail.

The story adds, "The researchers think it is possible that happy sorts are more likely to try to work through rocky spots in relationships. Alternatively, those with a sunny disposition may marry similarly upbeat souls. It is also possible that happiness is contagious."

Their findings are appearing in media reports around the world today, including in China Daily and the UK's Telegraph.

Last month, Professor Hertenstein authored an op-ed column which examined the downsides of American society's increasing discouragement of touch.

Research conducted by Hertenstein and his students at DePauw has previously been featured in American Baby and Prevention magazines, on the Canadian Broadcasting Corporation's program The Nature of Things, in Sunrise magazine and the Toronto Sun, and on National Public Radio.

"Decades of research has been done on the face and the voice and the distinct emotions that they communicate," reported NPR's Michelle Trudeau. "But touch had been relatively neglected by researchers until Hertenstein stepped in and began his experiments."
