In this final episode of Season 3 we actually do not talk about Darwin, but instead focus our attention to William James, a medical doctor, early psychologist, and philosopher who wrote about emotions about 20 years after Charles Darwin published The Expression of the Emotions in Man and Animals. Mark suggested we read James' views on emotion which he published first in his 1890 two volume set of his Principles of Psychology and then distilled in his single volume Psychology:Briefer Course. You can find reading editions of both books at the wonderful resource Project Gutenberg.

Season 3 Episode 10: Shame, Blushing, and Guilt

Mark, Sarah, and James discuss the last technical chapter of Charles Darwin's The Expression of Emotions in Man and Animals, Chapter XIII:  Self Attention, Shame, Shyness, Modesty: Blushing. Mark Jackson's graduate research was on shame and guilt and he explained to us the difference between shame, guilt, embarrassment, and humiliation (a concept Darwin did not address) and why they are actually distinctly different emotions. In our discussion Mark explains why parents and teachers should not shame their children/students, but employ guilt, the gift that keeps on giving, if a change in behavior is what you seek.

Darwin recognized blushing as a very distinct human behavior. In the chapter Darwin wrote:

In most cases the face, ears and neck are the sole parts which redden; but many persons, whilst blushing intensely, feel that their whole bodies grow hot and tingle; and this shows that the entire surface must be in some manner affected. Blushes are said sometimes to commence on the forehead, but more commonly on the cheeks, afterwards spreading to the ears and neck

We discussed the adaptive value of the blush as an honest signal that is exhibited in all humans, regardless of their skin color. Some of the studies we discuss indicated that when people see another blushing after being involved in a transgression or a mishap, the observer is more likely to give them sympathy or see them in a more positive light than if the person has a guilty or expression of shame without the blush.  Sarah discussed James' proclivity to blushing, and her warped sense of fun in making him blush.

Season 3 Episode 9: Fear, Anxiety, and Terror

 

We discuss Chapter XII of the text The Expression of the Emotions in Man and Animals. In this chapter Darwin explores the expressions we associate with surprise, fear, terror, horror, and anxiety. The stereotypical expression of fear, as represented by the image above from the 1950's horror film franchises,  has both a physiological function and a signal function. We discuss the various arguments Darwin made about the reason your eyes are opened wide, your mouth held agape, your hands held up. In this chapter Darwin used both photographs from Duchenne and woodcuts from photographs to illustrate the unique expressions humans employ when exhibiting that emotion.

We discussed how these expressions often illicit aid from others. In addition to people responding to the visual signal of fear, research has indicated that we also respond to the smell of fear. James discussed a study (Chen, Katdare, & Lucas 2006) where sweat samples generated from individuals who were either neutral or experiencing fear, as induced from watching scary movies, would trigger differences in cognitive abilities in third parties who smelled the sweat and then were tested for word association. 

We had a robust conversation about the apparent gender differences in the expression of anxiety. One of the complexities of this issue is untangling social norms and how they alter anxiety expression from biological differences that may alter anxiety expression.

Season 3 Episode 8: Disdain, Disgust, and Mark's secret time in Norway

 

Billy Idol and his trademark sneer

In 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 of the two '-ceits'. 

    Notice that her clothes are different in each image, she employed this expression frequently.

Mark explored the notion of disgust and explained how Darwin's narrowly applied use of disgust, an emotion associated only with tainted food, has now been expanded to include how we feel about social interactions and how the feeling of disgust may be the foundation of moral rules. We briefly mentioned the work of Jonathan Haidt and colleagues on this intriguing relationship between our concepts of disgust and how they relate to our ideas of moral rights and wrongs. If you want to see how you fair on the disgust scale visit this Yourmorals.org and take some of the questionnaires. Fascinating stuff.  

We closed talking about the potpourri of emotions discussed in the end of the chapter and how the shrug,  ¯\_(ツ)_/¯  and nodding yes in the affirmative and shaking your head no in the negative are not as universal as one would think, or Darwin would hope.

Season 3 Episode 7:Sulkiness & Hatred

 

Detail from Truth Coming Out of Her Well to Shame Mankind
Jean Leon Gerome 1896

In 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. We discussed the evolutionary value of the frown and why it is exhibited in so many contexts. 

We spent a lot of the time discussing Hatred and Anger and the unique and specific expressions associated with those emotions. James mentioned a memorable image that came out the Black Lives Matter marches in Montana where an older white man exhibits all of the expression characteristics Darwin lists for those in anger. 

Spencer Schacht ABC FOX Montana

"The mouth is commonly compressed, and there is almost always a frown on the brow. Instead of the frantic gestures of extreme rage, an indignant man unconsciously throws himself into an attitude ready for attacking or striking his enemy, whom he will perhaps scan from head to foot in defiance. He carries his head erect, with his chest well expanded, and the feet planted firmly on the ground. He holds his arms in various positions, with one or both elbows squared, or with the arms rigidly suspended by his sides. Darwin pg 242"

Mark and Sarah discussed how anger is associated with change, and expressions of anger seem to exhibit "emotional contagion" but in reality it is often more of a result of positive feedback system, i.e., your anger feeds my anger which then feeds back to your anger. 

Mark discussed an interesting study by  Ceccarini and Caudke (2013) that explored how readily do we recognize an angry or happy face in a crowd. Based upon images of known facial expression they altered the images to remove elements of the individual to create generic genderless face with a range of emotions.

With these images they could animate them to have changes in facial expression or they could show the still images within a montage of other expressions. They determined that humans are very good at quickly identifying both happy and angry expressions in a crowd, particularly when the face is opposite expression of the crowd. Recognition of angry faces was significantly faster than happy faces but the difference was only around 200 milliseconds faster showing that we are very sensitive to recognizing both happy or angry faces in a crowd of people exhibiting neutral or alternative expressions. 

There is a significant cost in exhibiting anger since the physiological changes associated with anger, increase in blood pressure, increase in heart rate, etc. are often linked to an increase in heart attacks. Darwin noted this in his book and modern research has focused on the role of expressions of anger and how management of anger can influence health outcomes.

Season 3 Episode 6: Happy, Happy, Joy, Joy

 

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" smile

The 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 sensations, I cannot doubt that some of the muscles running to the upper lip are likewise brought into moderate action. The upper and lower orbicular muscles of the eyes are at the same time more or less contracted...

Perfect for an audio podcast, we spent a long time discussing the value and accuracy of Plate III which was meant to illustrate various people in a state of happiness. Sarah thought the girl (bottom left, image 3) looked to be up to no good, she called her a minx!. We discussed how happy the man pictured on the right side of the page actually appeared to be.

 

We also discussed laughter and how it may have evolved as a false alarm call. Laughter is found to be exhibited in other apes. Interestingly, the variation in the sounds apes like gorillas, chimpanzees, orangutans, bonobos, and humans make when being tickled follows the same pattern of relatedness seen in the phylogenetic tree based upon genetic relatedness.

Season 3 Episode 5 - Sweet Spot of Grief

 

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 eyebrows are raised, the outer ends depressed while the corners of the mouth are drawn downward. Overall the face takes on an elongated expression and the furrows in the brow take on an distinctive horse-shoe shape. 

In the podcast we discussed how the chapters we have read from Darwin's text Expression of the Emotions in Man and Animals so far reads more like a field guide, with textbook description of the facial muscles involved in exhibiting the expressions, than a intellectual analysis of the adaptive value of the emotions. Sarah, so far, has not been impressed. We hope that will come later in the text. 

We all agreed that Grief is an emotion associated with loss and we explored in the podcast how universal is that view of grief and are there other emotions associated with grief that are universal? Sarah introduced us to a paper that examined how universal emotional concepts were in terms of linguistics and if there is similarity in emotional meaning across cultures. In seems that cultures in close geographical location share a greater similarity in meaning for identified emotions than cultures that are separated by distance. It seems that there are universal emotions but what feelings that are associated with those emotional states are varied and often culturally defined.

James questioned the adaptive value of adults exhibiting grief for the loss of non-related individuals. Sarah mentioned Neese's argument that we are expressing the loss of a known commodity - someone we have a strong relationship with that does not require accounting for altruistic behaviors - so their death is a loss felt as a loss of investment.
