Document Summary
~two conditions that show that facial expressions cannot be controlled voluntarily. Happens from damage to face region of primary motor cortex or damage to axons connecting primary motor cortex to facial nerve. Patient cannot voluntarily move those facial muscles, but if they laugh genuinely, they will involuntarily turn into a normal smile. Happens from damage to insular region of prefrontal cortex. People can move facial muscles voluntarily but not for a genuine emotional response. ~method acting developed by konstantin stanislavsky since facial expressions require genuine emotion, method acting is thinking of a scenario that elicits a response and that response is genuine. ~sociopaths have really good voluntary control over facial expressions. ~there is asymmetry in the recognition and expression of emotion. ~right hemisphere is better at judging facial expressions. ~left side of face (from right hemisphere of brain) is better at expressing facial expressions.
