Facial Expressions Research Paper

There are two neural pathways that mediate facial expressions, each originating in a different area of the brain (Rinn, 1984).The pyramidal tract drives voluntary facial actions and originates in the cortical motor strip, whereas the extrapyramidal tract drives involuntary emotional expressions and originates in subcortical areas of the brain.Since the original universality studies more than 30 studies examining judgments of facial expressions have replicated the universal recognition of emotion in the face (reviewed in Matsumoto, 2001).

These findings are impressive given that they have been produced by different researchers around the world in different laboratories using different methodologies with participants from many different cultures but all converging on the same set of results.She is an author of a number of scientific publications and conference presentations in this area and is co-editor, with David Matsumoto and Mark Frank, of an upcoming book entitled Emotions are an incredibly important aspect of human life and basic research on emotions of the past few decades has produced several discoveries that have led to important real world applications.In this article we describe two of those discoveries – the universality of facial expressions of emotion and the existence of microexpressions – because of their importance to and novelty in psychology.Darwin (1872) was the first to suggest that they were universal; his ideas about emotions were a centerpiece of his theory of evolution, suggesting that emotions and their expressions were biologically innate and evolutionarily adaptive, and that similarities in them could be seen phylogenetically.Early research testing Darwin’s ideas, however, was inconclusive (Ekman, Friesen, & Ellsworth, 1972), and the dominant perspective in psychology was that facial expressions were culture-specific – that is, just as every culture had its own verbal language, it had its own language of facial expressions.Stanley Hall lecturer by the American Psychological Association.He is the series editor for Cambridge University Press’ series on Culture and Psychology and is Editor-in-Chief for the .The idea that microexpressions exist has its roots in Darwin’s (1872) inhibition hypothesis that suggested that facial actions that cannot be controlled voluntarily may be produced involuntarily even if the individual is trying to control his or her expressions.Research on the neuroanatomical bases of emotional expressions suggests how this occurs.She is an expert at the Facial Action Coding System and in the conduct of research examining facial expressions and other nonverbal behaviors.She is co-creator of many of the training tools used to teach law enforcement officers and many other individuals how to recognize micro and subtle facial expressions of emotion.
