Emotion: are we different

Part 1:  Look at the images below from a research article looking at the expression of emotions in a blind versus sighted athlete (San Francisco State University. “Facial Expressions Of Emotion Are Innate, Not Learned.” ScienceDaily. ScienceDaily, 30 December 2008) .  How can a man from a tribe in New Guinea express emotions the same as ours? How can a blind woman, who has never “seen” an emotion expressed use the same facial expression. Explain your answer using your understanding of the brain.
