Missed Signals

From Greater Good

Researchers tested people before and two weeks after they received a Botox treatment that paralyzed the brow-wrinkling muscles used in frowns. During the test, they were asked to read sentences describing an emotional situation that made them happy, sad, or angry. In each case, the participants had to give a signal as soon as they had understood the sentence.

The results showed that after the Botox treatment, participants took longer to understand sentences with sad and angry emotions—the emotions typically expressed by the kind of furrowed brow that the participants were no longer capable of making, thanks to the Botox.

These findings point to a complicated relationship between expressing emotions and feeling them. The authors write that their findings back up the “facial feedback hypothesis,” which claims that your facial expressions influence both your emotions and your interpretation of emotional signals: If you aren’t capable of displaying sad or angry facial expressions, for instance, then you won’t feel or see those emotions out in the world as much.
