Discovering Darwin

 Billy Idol and his trademark sneerIn this episode of Mark, Sarah, and James discuss Chapter XI from Darwin's text The Expression and Emotions in Man and Animals, 3rd edition. Sarah noted that this chapter was a potpourri of emotions, including: Scorn, Disdain, Contempt, Disgust, Jealousy, Envy, Avarice, Revenge, Suspicion, Deceit, Slyness, Guilt, Vanity, Conceit, Ambition, Pride, Humility, Helplessness, Impotence, Affirmation, *heavy sigh*...and Disapproval.Darwin's use of images in this chapter, to James, were not too convincing. Here is plate 1 in this chapter. Looks more like a silent film serial actor than a real expression of contempt.We compared the role of classic sneer expression in the modern place and how it has morphed into more subtle expressions or verbal components. James brought up the common expression Sarah Huckabee Sanders gave as one of the many press secretaries in the previous presidential administration. Her expression seemed to be a chimera of emotions- Contempt + Disdain + a dash

 Detail from Truth Coming Out of Her Well to Shame MankindJean Leon Gerome 1896In this episode we discuss both Chapters IX & X from Darwin's The Expression of the Emotions in Man and Animals. Chapter IX dealt with the interesting phenomenon of the frown - a telltale expression we exhibit when we are disappointed, sad, or confused. Darwin notes:"From these considerations, we may conclude that frowning is not the expression of simple reflection, however profound, or of attention, however close, but of something difficult or displeasing encountered in a train of thought or in action. Deep reflection can, however, seldom be long carried on without some difficulty, so that it will generally be accompanied by a frown".We discussed how the frown is an expression that rarely exhibits "emotional contagion" where others mirror the expression once they see it in someone else. Unlike smiles, which strangers can elicit into others about 20% of the time, frowning at strangers does not result in them frowning back.

 In this episode of Discovering Darwin we tackle Chapter VIII - Joy, High Spirits, Love, Tender Feelings, Devotion in Darwin's book The Expression of the Emotions in Man and Animals. In this chapter Charles explores how we express ourselves when we are happy, in particular he discussed the two expressions associated with a happy mental state - smiling and laughing. Mark, Sarah and I explore what a "real" smile looks like, why we fake it sometimes, and why women more often fake it. Clearly a Duchenne "D" smileThe Duchenne smile is defined by the contraction of the obicular muscles that surround the eyes and the raising of the lips to expose the upper teeth. Darwin describes it as:Dr. Duchenne repeatedly insists that, under the emotion of joy, the mouth is acted on exclusively by the great zygomatic muscles, which serve to draw the corners backwards and upwards; but judging from the manner in which the upper teeth are always exposed during laughter and broad smiling, as well as from my own s

 Persons suffering from excessive grief often seek relief by violent and almost frantic movements, as described in a former chapter; but when their suffering is somewhat mitigated, yet prolonged, they no longer wish for action, but remain motionless and passive, or may occasionally rock themselves to and fro. The circulation becomes languid; the face pale; the muscles flaccid; the eyelids droop; the head hangs on the contracted chest; the lips, cheeks, and lower jaw all sink downwards from their own weight. Hence all the features are lengthened; and the face of a person who hears bad news is said to fall. [Charles Darwin. opening of Chapter VII, EEMA] In this episode we discussed Chapter VII - Low Spirits, Anxiety, Grief, Dejection, Despair. Although the title of the chapter covers a variety of emotions, we, following Darwin's lead, focused solely on grief. Darwin identified a group of muscles that are involved in creating the grief-stricken visage we are familiar in others. The inner ends of the ey

 "The fact of tears not being shed at a very early age from pain or any mental emotion is remarkable, as, later in life, no expression is more general or more strongly marked than weeping."  pg 154 EEMA Charles Darwin. In this episode we explore Chapter VI: Suffering and Weeping where Darwin describes in excruciating detail the muscles involved in the crying face of infants and how tears are formed in the lacrimal glands. This chapter is the first one in the book to use photographic images to represent the expression of the emotions Darwin is describing. We discussed Plate 1 in detail and it can be seen here:Sarah discussed Duchenne's original photograph that Darwin showed people to see if they could recognize the emotion based upon the stimulation of specific facial muscles.  In the 3rd Edition of the book, Ekman includes the original photograph that was not actually in the earlier editions of the book.James discussed his amazement on where in his body tears are made, and where they go ul
