Lie Detection
• James’s theory forms basis.
• Polygraphs monitor physiological activity.
• Different approaches:– Control question test.– Directed lie test.– Guilty knowledge test.
Accuracy of Polygraphs
• Estimate vary widely.– A guilty person can “fool” a polygraph.– Some innocent people can be mislabeled as
guilty (false positive).
Cannon-Bard Theory

Updating Cannon’s Theory
• Thalamus is not the “seat” of emotion.
• Specific brain areas produce the feelings of pleasure or discomfort associated with emotion
Schachter-Singer Theory
• Cognitive Interpretation/Appraisal• Unambiguous
– Excitation transfer
• Ambiguous– Misattribution

Main Criticism of Appraisal Theories
• Emotion without “cognition”– fear conditioning without explicit knowledge– emotion without awareness
Communicating Emotion
How Do We CommunicateEmotions to One Another?
• Through words.– Women talk about their emotions and the
complexity of their feelings.
• Through body movement and posture.– Especially through facial movements and
expressions.
Innate Expressions of Emotion
• Darwin’s universal facial expressions.– hard-wired
• Supporting evidence– newborns– cross-cultural– blind persons

Cultural Influences
• Cultural variations in recognizing some emotions.
• Smiles vary as people learn to use them to communicate certain feelings through operant conditioning.
• Expression of emotion affected by cultural rules, called emotion culture– “stiff upper lip”
Social Influences and Emotion
• Social Referencing– Adult (Offensive or Not?)– Infant (OK Mom?)
“Are these OK, Mom?”
Physiology• Body
– Arousal– Facial
• Involuntary/voluntary facial displays
• Some Brain Areas– Amygdala (fear)– Hypothalamus (attacking rage, defensive rage)– Lateralization
• Right brain dominant• Right amygdala (negative emotions)
– Cerebral cortex• Regulates Emotion (frontal inhibits aggression)• Serotonin = Inhibitory Effect On Anger
