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.

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

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

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.

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
