Can we detect a liar? 3 Volunteers will try to lie to the class. They can either take or not take a dollar

from an envelope & must successfully lie to us to keep the dollar & gain a candy bar (Woohoo! Extrinsic Motivators!).

They will enter the class at the same time & must answer any (reasonable) question that we ask of them to help us discern if they are lying or not.

Facial Expression of Emotion Paul Ekman had people from different

cultures identify various facial expressions & found they all responded similarly.

(But study was invalid) Ekman had the Fore Tribe in New Guinea

match up photographs of facial expressions to events in stories. Same results as first study.

Some Facial Expressions are universal indicators of emotion.

Anger Catharsis- releasing pent-up frustration

& aggression to provide relief from these feelings.

Research shows that Anger Catharsis does not work. Acting aggressively only encourages more aggression/frustration. This is an example of behavior feedback.

“I don’t care what anyone says. Boys need to be physical. Thye need an outlet for all of their aggression. It’s better they do it on the football field than in school.”B.

James-Lange Theory of Emotion

Physiological Arousal and THEN Emotion Ex. We feel sad because we cry. Ex. We feel happy because we smile.

Problems: 1) Some Emotions have same physiological response. (Ex. Fear, Anger, & Sexual Arousal all Similar)

2) People can experience arousal w/o experiencing emotion.

(Running)

3) Physiological responses happen to slow to cause emotion.

4) What about people with spinal cord injuries?

Emotions are the combination of physical arousal & a cognitive label.

When you are aroused, you look to your environment for an explanation of the arousal.

(If aroused while in a mob of protestors, you might label your arousal “Anger”)

(If aroused at a concert, you might label your arousal “Excitement)
