3. Warm Up- Quick write Read Pages 508-509 and answer the following question Read Pages 508-509 and answer the following question Discuss the effectiveness if the polygraph in detecting lies. Discuss the effectiveness if the polygraph in detecting lies.

4. The Physical Arousal of Emotion is Controlled by The Autonomic Nervous System It is very difficult to differentiate the physical arousal associated with many emotions (hurts James-Lange Theory) even though they definitely feel different. It is very difficult to differentiate the physical arousal associated with many emotions (hurts James-Lange Theory) even though they definitely feel different. The arousal associated with emotions are controlled by the autonomic nervous system’s divisions the sympathetic and parasympathetic nervous systems. The arousal associated with emotions are controlled by the autonomic nervous system’s divisions the sympathetic and parasympathetic nervous systems.

5. Autonomic Nervous System’s Division Autonomic nervous system controls physiological arousal Sympathetic division (arousing) Pupils dilate Decreases Perspires Increases Accelerates Inhibits Secrete stress hormones Parasympathetic division (calming) Pupils contract Increases Dries Decreases Slows Activates Decreases secretion of stress hormones EYES SALIVATION SKIN RESPIRATION HEART DIGESTION ADRENAL GLANDS

6. Arousal’s Impact on Performance Review: Review: What types of tasks are performed best with high amounts of arousal? What types of tasks are performed best with high amounts of arousal? What types of tasks are performed bets with low amounts of arousal? What types of tasks are performed bets with low amounts of arousal?

8. Can Measuring Arousal Detect Lies? Polygraph: machine commonly used to in attempts to detect lies. Polygraph: machine commonly used to in attempts to detect lies. Measures Physiological Responses to Emotion Including: Measures Physiological Responses to Emotion Including:  perspiration  heart rate  blood pressure  breathing changes

9. Questioning Process With The “Lie Detector” 1. Ask Control Question which you are most likely guilty of (Probable lie). 1. Ask Control Question which you are most likely guilty of (Probable lie). –Have you ever stolen anything? 2. Ask Relevant Question that you are interested in. 2. Ask Relevant Question that you are interested in. –Were you at the scene of the crime the day of the murder? If there is a bigger physiological reaction to the relevant question than the control question you are lying. If there is a bigger physiological reaction to the relevant question than the control question you are lying.

10. What Arguments Do Critics Make Against the “Lie Detector?”

11. Accuracy of the Polygraph Is Between 70 & 90% Is this a good level of accuracy? Is this a good level of accuracy? With 70% Accuracy: With 70% Accuracy: –Assume 5% of 1000 employees actually guilty  test all employees  285 will be wrongly accused With 95% Accuracy: With 95% Accuracy: –Assume 1 in 1000 employees actually guilty  test all employees (including 999 innocents)  50 wrongly declared guilty

12. Polygraph Accuracy Study Percentage Innocent people Guilty people 80 70 60 50 40 30 20 10 0 Judged innocent by polygraph Judged guilty by polygraph

15. The Emotion of Fear Fear is an adaptive emotion which helps prepare us for dangerous situations but which can also negatively impact us. Fear is an adaptive emotion which helps prepare us for dangerous situations but which can also negatively impact us. Some fears are more innate than others but there have been experiments which have shown fears can be learned. Some fears are more innate than others but there have been experiments which have shown fears can be learned. –Ex: Monkeys and snakes and Certain phobias

16. Biology of Fear The body’s control center for learning/enacting fear is the amygdala. The body’s control center for learning/enacting fear is the amygdala. Loss or damage to one’s amygdala has lead to fearlessness in some patients. Loss or damage to one’s amygdala has lead to fearlessness in some patients.

17. The Emotion of Anger: Is the Catharsis Theory True? Catharsis: refers to an emotional release. The hypothesis argues that by releasing aggressive energy on can relieve their aggressive urges.

Predicting Happiness Researchers Have Found That Happy People Tend to Have high self-esteem (in individualistic countries) Be optimistic, outgoing, and agreeable Have close friendships or a satisfying marriage Have work and leisure that engage their skills Have a meaningful religious faith Sleep well and exercise However, Happiness Seems Not Much Related to Other Factors, Such as Age Gender (women are more often depressed, but also more often joyful) Education levels Parenthood (having children or not) Physical attractiveness
