It takes just one-tenth of a second for our brains to begin to recognize emotions conveyed by vocalizations, according to researchers from McGill. It doesn’t matter whether the non-verbal sounds are growls of anger, the laughter of happiness or cries of sadness. More importantly, the researchers have also discovered that we pay more attention when an emotion (such as happiness, sadness or anger) is expressed through vocalizations than we do when the same emotion is expressed in speech.
When people talk or sing, they often nod, tilt or bow their heads to reinforce verbal messages. But how effective are these head gestures at conveying emotions?
Very effective, according to researchers from McGill University in Montreal. Steven R. Livingstone and Caroline Palmer, from McGill’s Department of Psychology, found that people were highly accurate at judging emotions based on head movements alone, even in the absence of sound or facial expressions.
