Chapter 13: Emotion A response of the whole organism and how the pieces of that response fit together
Three Components of Emotion Physiological arousal Expressive behaviors (flush cheeks, fidgeting, pacing) Conscious experience (i.e. thoughts & feelings) Controversies: Chicken & the Egg Cognition & Arousal
Theories of Emotion James-Lange Theory (William James & Carl Lange) Physiology → expressive behaviors → conscious experience Cannon-Bard Theory (Walter Cannon & Philip Bard) Physiology + expressive behaviors = conscious experience Two-factor Theory (Stanley Schachter and Jerome Singer) Physical + cognitive label = conscious experience
Embodied Emotion Emotions and the Autonomic NS Pg. 516 – chart (sympathetic & parasympathetic) Sympathetic NS Adrenal glands = kidneys → adrenaline & noradrenaline Incr. h.r., b.p., & blood sugar Parasympathetic NS Inhibits further release of hormones Gradual decrease in arousal Performance of tasks Easy tasks – high arousal = best performance Difficult/unrehearsed tasks – moderate to low arousal = best
Embodied Emotion Physiological Similarities Physiological Differences Fear, anger, & sexual arousal – similar physical arousal Physiological Differences Different facial expressions Different brain pathways Left frontal lobe = happy/positive personalities Dopamine receptors Right frontal lobe = depressed/negative personalities
Embodied Emotion Cognition & Emotion Spill over effect - Arousal from one event affects another Interpreting info/labeling affects what emotion we feel Easier for feelings to hijack thought than vice versa Short-cut to amygdala & more to cortex than from cortex Some emotions (likes/dislikes) are not conscious processes (Zajonc & LeDoux) Complex emotions are greatly affected by cognition (Lazarus, Schachter-Singer)
