Relationship between emotions and muscle tension in oro-alimentary behavior.
The relationship between muscular tension in the right and left masseter and orbicularis oris and different forms of hostility measured through the Gottschalk test was examined for 24 female subjects. For the muscles of the right half of the body a direct relation was noted with overt outward hostility, while on the left half of the body only the tension of the masseter was related directly to ambivalent hostility. Our hypothesis about a link between modulation of aggressive behaviors and muscles involved in functions such as chewing and biting was confirmed.
