Document Summary
Emotional situations arouse the autonomic nervous system sympathetic and parasympathetic. Sympathetic ns (fight or flight responses ex. Nausea stimulation of the stomach, decreasing its contractions and secretions) Parasympathetic (increases digestion and other processes that save energy and prepare for later events stimulation of intestines and salivary glands) Commonsense view (you feel an emotion, change heart rate, response) James-lange theory (autonomic arousal and skeletal actions come first, and then you feel an emotion ex. You feel afraid because you run away; you feel angry because you attack) Cognition (you quickly appraise something as good, bad, frightening, etc. ) Actions (appraisal of situation from cognition leads to an action running away, attacking, etc. ) Emotions do not require feedback from muscle movements. Spinal cord damage (paralysis from damage location and downwards does not affect autonomic nervous system) Botulinum toxin (botox inability to frown interferes with processing unpleasant information slower at reading unhappy sentences feeling a body change is important for feeling an emotion)
