Unformatted text preview: Psychology Study Guide #3 Module 38: Introduction to Emotion 1. What are emotions? a. Emotions are a mix of three things: i. Physiological arousal (heart pounding) ii. Expressive behaviors (quickened pace) iii. Conscious experience, including thoughts and feelings 2. Describe and be able to recognize examples illustrating the three primary theories of emotions. How are these similar? What evidence supports each theory? a. James-Lange Theory: the theory that our experience of emotion is our awareness of our physiological responses to emotion-arousing stimuli. i. Walter Cannon thought the bodys responses were not distinct enough to evoke the different emotions. Does a racing heart signal fear, anger, or love? Cannot tell. b. Cannon-Bard theory: the theory that an emotion-arousing stimulus simultaneously triggers physiological responses and the subjective experience of emotion. c. Two-factor theory: Schachter-Singers theory that to experience emotion one must be physically aroused and cognitively label the arousal. d. These are similar because they all include a physical arousal emotion. 3. What is the role of the autonomic nervous system in emotional arousal? a. Autonomic nervous system mobilizes your body for action. i. To provide energy, your liver pours extra sugar into your bloodstream. To help burn the sugar, your respiration increases to supply Oxygen. Your digestion slows, diverting blood from your internal organs to your muscles. With blood sugar driven into the muscles, running becomes easier. Your pupils dilate, letting in more light. To cool your stirred-up body, you perspire. If wounded, your blood would clot more quickly. b. Arousal and Performance i. Prolonged arousal taxes the body. But in many situations arousal is adaptive. Too little arousal can be as disruptive as too much. 4. What are three emotions that have similar physiological arousal patterns? What are the physiological differences between specific emotions? a. The three emotions that have similar physiological arousal patterns are fear, anger, and sexual arousal. b. For differences, READ pp. 517-519. 5. What is the polygraph and how does it measure emotional response? What are the assumptions underlying the use of the polygraph in crime investigations? How are these assumptions problematic? What is the guilty knowledge test? How often do lie detectors lie? a. Polygraph: a machine, commonly used in attempts to detect lies, that measures severall of the physiological responses accompanying emotion (such as perspiration and cardiovascular and breathing changes). b. The assumption underlying the use of the polygraph in crime investigations has...
