Document Summary

Mood: no particular response to stimulus, not short lived, tend to permeate for weeks/months, can be intense but can diffuse/ not always conscious, experience, positive/negative. James-lange (facial-feedback hypothesis: stimulus -> physiology -> emotions. Cannon-barde: stimulus -> physiological and emotional reaction (independent of each other) Schacter-singer: 2-factor theory, stimulus -> physiological/apply cognitive label -> emotion. Spillover effect/ misattribution of arousal: take the wrong cue from the environment but not from people. Micro-expressions (short burst of facial expression: gives us insight to what we are concealing. Hypothalamus -> pituitary gland -> adrenal cortex -> cortisol (long route) Increases sugar in the blood system: redirect blood-flow (away from stomach to the muscles, sustained action, hpa -> cortisol, long route to action. Get the heart pumping: hypothalamus -> adrenal medulla -> adrenaline (short route, adrenaline, pupils dilate, heart rate increases, breathing rate increases, blood pressure increases, sam (sympathetic adrenal medulla, adrenaline, fast action. Surge of adrenaline: cannon (1932) fight or flight response.
