You smile, you are happy. Not necessarily. The smile does not reflect not always an inner state of well-being. It can also be a social interaction tool. This is shown by Dr. Harry Witchel, author of the study.
To arrive at these conclusions, he gave a complicated geography quiz to 44 participants between the ages of 18 and 35. They had to answer it on a computer and their faces were videotaped during the test in order to record the moments when they smiled and the emotion that was felt.
A smile, a sign of commitment
The recording of faces and emotions showed that during the experiment, the smile was not associated with a happiness type emotion, but rather to an emotion of type subjective engagement. Indeed, test participants smiled more when the computer informed them that their answer was wrong rather than right!
This shows that the smile is a tool for social interaction and not, necessarily and exclusively, a state of cheerfulness.
