19. Theory The specific facial expressions corresponding to basic emotions are universal.

20. Ah, but how to get an truly accurate experiment : With the pervasiveness of Western culture, how can we be sure that our influence isn’t messing with the results?  even in 1971 when this study was performed Go to the southern New Guinea and study an isolated group called the Fore people.

21. Method:  Chose 189 adults and 130 children  Showed them faces  one was correct emotion, other(s) were obviously incorrect  Told a quick story to set up a scenario where the emotion would happen  “he is looking at something that smells bad.”  Asked to choose the photo that corresponded with the story.

22. Results  Fear and surprise were a slight issue but:  Happiness92.3% correct  Anger85.3% correct  Sadness79.0% correct  Disgust83.0% correct  Surprise68% correct  Fear80.5% correct  Fear (with surprise) 42.7% correct

23. Results  Compared to Westerners there were no significant differences.  Children compared to adults also showed no significant differences.

24. To double check their findings  Ekman and Friesen videotaped members of the Fore culture portraying the same six facial expressions.  Later, when the tapes were show to college student in the U.S., the students correctly identified the expression corresponding to each of the emotions.

25. Why does this matter?  In the nature/nurture debate this gives us a pretty clear picture that these six emotions have a biological (hard-wired from birth) origin.  Evolutionarily speaking …  the expressions are possibly a silent indicator to ensure survival. An expression of fear would silently signal the approach of a predator. An expression of disgust may signal possible poisons.

26. Leftover survival instincts  It is easier to detect an angry face in a crowd than it is to find a happy one.

27. Recent applications  A study of children diagnosed with autism  pervasive developmental disorder marked by language deficits, social withdrawal and repetitive self-stimulation behaviors  appear to have difficulty recognizing the facial expressions that correspond to basic emotions.  Fundamental in cross-cultural psychology research.  And finally, animals and the existence of eyebrows.

28. Ekman & Friesen  Also studied polygraph testing/lie detecting  Video Clip Video Clip  Emotions & lying  Video clip Video clip

29. Emotion-Lie Detectors Polygraph  machine commonly used in attempts to detect lies  measures several of the physiological responses accompanying emotion  perspiration  cardiovascular  breathing changes

34. Emotion--Lie Detectors  Is 70% accuracy good?  Assume 5% of 1000 employees actually guilty  test all employees  285 will be wrongly accused  What about 95% accuracy?  Assume 1 in 1000 employees actually guilty  test all employees (including 999 innocents)  50 wrongly declared guilty  1 of 51 testing positive are guilty (~2%)
