Unlocking secrets behind human emotion may lead to better therapies for people with communication deficits
Toronto, Ontario: Understanding how different senses contribute to the expression of emotion may lead to developing better therapies for those who have communication deficits, says a Ryerson University researcher.
Frank Russo is the director of the SMART (Science of Music, Auditory Research and Technology) laboratory. He is also one of two Ryerson scientists awarded the prestigious Early Researchers Award (ERA) by the Ministry of Research and Innovation this year so he can further his research in vocal emotional communication. (The other is Professor Habiba Bougherara, Department of Mechanical and Industrial Engineering).
“Increasing evidence suggests when you perceive emotion in communication, you are using your brain to simulate the observed emotion at an unconscious level,” says Russo. “By engaging this neural-stimulation system, we are better able to understand what others are feeling.”
Over the next five years, Russo and a team of 12 student researchers, from the undergraduate to post-doctoral level, will track the eye movements, facial muscles, tone/pitch and brainwaves of participants conveying emotion through song and speech. The patterns in tone and pitch of their voices will also be analysed to provide clues to any correlation with their facial and eye movements.
Song will be a big part of his research since Russo says that it tends to be a “purer” representation of an emotion such as anger or sadness.
“Songs are all about using emotions to communicate so it’s helpful for us to study songs as an overt form of emotional communication to understand more subtle forms in speech.”
Russo’s current research in vocal emotional communication builds on his previous work, which examined perception of music through auditory and non-auditory channels. Most notable is his work in co-developing the Emoti-Chair with Ryerson Professor Deborah Fels, a chair-like device that enables hard-of-hearing and deaf people to “hear” music through vibrations.
“Whether it is the Emoti Chair or his current work on human emotion, Frank Russo is always ahead of the curve,” says Jean-Paul Boudreau, Dean of Arts. “Russo is a leader in the field of vocal emotional communication, and the prestigious ERA award is just one example of the growing recognition of his stature in the science community.”
Looking to the future, the psychology professor hopes that his research on vocal emotional communication will enable researchers to develop better therapies for those who have communication deficits.
“If we have a more complete understanding of how senses are integrated, this may lead to solutions for developing therapies for people who have communication deficits.”
