Botox may help keep anger, sadness at bay | Botox can prevent people from experiencing negative emotions, according to a new study. Botulinum toxin type A (BTX) - known as Botox - is used to paralyze facial muscles
that control frowning and relax the surrounding skin wrinkles. However, this common
cosmetic treatment administered to reduce frown lines can delay patients' recognition
of anger and sadness around them. "Botox induces a kind of mild, temporary cognitive
blindness to information in the world, social information about the emotions of
other people," Discovery News quoted David Havas, lead study author and a psychologist
at the University of Wisconsin-Madison, as saying. For the study, Havas and colleagues
evaluated 40 first-time Botox patients before, and then two weeks after, they
underwent treatment. On both occasions, the participants read happy, sad or angry
statements, and pushed a button to indicate their comprehension of the text. After
receiving the Botox injections, it took longer for the frown-impaired participants
to process the angry and sad statements. However, the time required to process
happy statements did not change. The results of the study support the "facial
feedback hypothesis," which states that physical expressions, such as grinning
or grimacing, signal our brains to produce emotional responses. In this case,
the Botox injections prevented frowning, and so delayed the perception of negative
statements. The study is to be published in the journal Psychological Science. |
