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
