TOPICS RELATED TO CHAPTER 12 (i.e., lecture 20) 20.1 How do the James-Lange theory, Cannon-Bard theory, and Schachter’s Cognitive Model differ? The James Lange Theory says that physiological changes determine the experience of an emotion and predicts that people with a weak autonomic or skeletal response have impaired emotion. EVENT COGNITION OF EVENT AUTONOMIC AND BEHAVIORAL RESPONSE FEELING Ex. A stimulus (like a man with a gun) leads to a physiological event (faster heartbeat perhaps) that leads to an emotion (being afraid) The Cannon-Bard Theory says that emotional expression and physiological experience take place simultaneously by way of thalamic stimulation; predicts that the thalamus controls emotional expression EVENT THALAMUS PHYSIOLOGICAL RESPONSE AND BEHAVIOR Schachter’s Cognitive Model says that if one is unable to identify the cause of physiological arousal, a person will attribute it to environmental conditions EVENT ATTRIBUTION FEELING Ex. It is possible to misattribute arousal to the environment when, in reality, something else is responsible What experiments have been devised to support the James-Lange theory? 1) Looking at paralyzed people 2) Patient with “Pure Autonomic Failure” had no increase in heart rate upon the event; they report cognitive state but less intense (perhaps they do not feel emotion itself) 3) Panic attacks 4) Lesions/stimuluation and brain damage – prefrontal cortex damage = no emotions 5) PET and fMRI during exposure to emotionally stimulating events 6) Transcardial magnetic stimulation (inactivates brain region – ex. Medial fronal cortex = no recognition of anger) What are the divisions of the limbic system? The limbic system is the forebrain areas surrounding the thalamus and the divisions are: 1) Sub-circuit 1: defensive aggression survival - Amygdala - Hippocampus 2) Sub-circuit 2: pleasure - Cingulate gyrus - Septum - Hypothalamus 3) Sub-circuit 3: cooperative social behavior - Thalamus - Hypothalamus What is the Papez circuit? It is a system of interconnected forebrain structures that are responsible for the expression and experience of an emotion (The part of the limbic system that controls emotion) 20.2 Happiness What are the qualities of people with left versus right frontal cortex dominance? Left frontal cortex dominance: happier, outgoing, fun-loving Right frontal cortex dominance: socially withdrawn, less satisfied with life, prone to negative emotions In what way is amygdala function lateralized? Right amygdala dominance: more sensitive to emotional events How do oxytocin levels change in the blood upon the recall of sad and happy events? 1)
