Document Summary
People"s definition of emotion is a conscious feeling that"s unobservable. Thus: scientists focus on emotional behaviours that are observable. Emotion: 3 components: cognition, feelings, and actions: where feelings are most central. Ex: you can have cognition and action, but feeling is the necessary aspect. A mix of sympathetic (fight v flight) and parasympathetic activity. James-lange theory: emotional events lead to cognition to action to feelings. If true then decreased autonomic/skeletal response leads to decreased emotion; Paralyzed people: feel emotion just as well as before their paralysis. But: paralysis doesn"t affect ans so they still have emotion input from that. Pure autonomic failure: ans can"t regulate responses (bp etc. ) People with paf still have same emotions as others but report less emotional response. If you increase sympathetic response without one having an explanation (such as exercise) Leads to the person attributing it to emotion (ex fear) Increased breathing leads to a panic attack, repeated panic attacks + worry over another->disorder.
