Sapolsky, Behave, C 14, (521-535, 542-552; 24)

• starts with "exposure to an aversive state" -- we call it empathy, but what is that?

q1: When does empathy lead us to actually do something helpful?

q2: When we do act, whose benefit is it for?

• sympathy -- feeling sorry for someone's pain. But could also convey distance or power diff. pity.
• empathy -- includes a cognitive step of understanding the cause of someone's pain and "taking perspective"
• compassion -- S. suggests this involves empathy plus taking action.

• Emotionally contagious, compassionate animals.

• we are 'overimitative' - chimp / kids study524
• mouse studies -524- alterations of sensitivity to pain on seeing pain; fear association seeing another mouse exp fear conditioning. Mouse depression ensues! research suggesting mice respond proportionally and to social group (cagemates).
• Consolation: lots of species engage in consolation, chimps show third party consolation behavior, no consolation behavior in monkeys (another reason not to trust monkeys) -- prairie voles!
• 526: rats, amazing rats -- US/them behaviors, some flexibility. review the details.

• Emotionally contagious, compassionate children

• 527: describes mechanism of empathy: early emo contagion in kids may not be linked to cognitive judgement as later, when Theory of Mind emerges. Neural activity follows this progression. “As the capacity for moral indignation matures, couple among the vmPFC, the insula, and amygdala emerges.” Perspective taking adds other connections.

• Affect and /or Cognition?

• Affective side of things.

• Some neurobiology: the ACC - anterior cingulate cortex - processes interoceptive info, conflict monitoring, (presumably cog. dissonance). susceptible to placebo effect. ACC activates when our internal and external “schemas” of the world are amiss.
• Importantly, ACC activates on social exclusion (Cyberball game), anxiety, disgust, embarrassment, but also pleasure, mutual pleasure. (ACC activation is maybe a good proxy for the state that empathy and compassion address: We help each other settle our ACCs down.). Empathic responses involve our ACC, which is activated by your pain.

• ACC also involved in action circuits. Oxytocin, hormone related to bonding. Block it in voles and they don't console. Awwww!

• How does self-interested "alarm" system of the ACC get involved in empathy? Sapolsky's hypothesis 530: Feeling someone's pain can be more effective for learning than just knowing that they're in pain. Empathy may also be a self-interested learning system, separate from helping action. Maybe not a “moral emotion” until we use it that way.

• Cognitive side of things: How do we bring judgements about desert and character to bear on empathic responses? Chimps do. They only console victims. Reason allows us to shut down empathic responses.

• One of Sapolsky’s weirder analogies at 532 re: the militia leader.
• Cognition comes in with emotional pain, judgement abstractly represented pain (a sign), unfamiliar pain. (Takes more cog resources to process others' emo pain.) Also with Thems. 533.
• socioeconomics of empathy 534: wealth predicts lower empathy. Less likely to stop for pedestrians. the wealthy take more candy! (This can be primed by asking test subjects to make upward or downward comparisons prior to the choice event.)
• especially hard, cognitively, to empathize with people we don't like, because their pain actually stimulates a dopamine response! Empathy is part of our preference network behaviors!

• The Core Issue (in Empathy): Actually doing something.

• S resumes the topic of the 1st half of the chapter. Empathy can be a substitute for action. "If feel your pain, but that's enough." In adolescents (chapter 6) empathy can lead to self-absorption. It hurts to feel others pain when your "you" is new.

• 543: research predicting prosocial action from exposure to someone's pain: depends upon heart rate rise, which indicates need for self-protection. 543: "The prosocial ones are those whose heart rates decrease; they can hear the sound of someone else's need instead of the distressed pounding in their own chests." (Echoes research showing less prosocial behavior to strangers under cognitive load, hunger condition, social exclusion, stress. Block glucocorticoids and empathy goes up.)

• Research on Buddhist monks, famously Mathieu Ricard (digress). without Buddhist approach, same brain activation as others. with it, quieter amygdala, mesolimbic dopamine activation - compassion as positive state. (Mention hospice, compassionate meditation.). Ricard reports “a warm positive state associated with a strong prosocial motivation.” (Very much like the experience of hospice volunteering.)

• Evidence from “empathy training” of similar change in neural activation.

• Doing something effectively

• empathy disorders and misfires: "Pathological altruism"; empathic pain can inhibit effective action. Doctors and others need to block empathy to have sustainable careers.

• Is there altruism?

• 2008 Science study: we predict spending on ourselves will increase happiness, but only altruistic uses of the money did so in the study.

• S suggests that given the design of the ACC, and the abundant ways the social creatures get rewards from prosocial reputations (reputation, debts to call in, extra benefits in societies with moralizing gods), maybe we shouldn't be looking for "pure" altruism. (recalls that belief in moralizing gods increases prosocial behavior toward strangers.) some evidence charitable people are raised that way and transmit the trait through family life. 548

• reminder of Henrich on "moralizing gods" and “contingent afterlives”. Probably helped humans become comfortable in urban environments.

• Empathy and reputational interests - Research subjects in brain scanner given money and option. Dopamine response depended upon presence of an observer.

• Final study of the chapter. 2007 Science, test subjects in scanners, given money, sometimes taxed, sometimes opp to donate. Hypothesis: If one is purely altruistic, you would expect identical dopamine responses. Follow results 549:

• a. the more dopamine (pleasure response) you get in receiving unexpected money, the less you express in parting with it - either voluntarily or not.
• b. more dopamine when taxed, more dopamine when giving voluntarily. Seems to identify a less self-interested person. Could also be "inequity aversion" - we sometimes just feel better when a difference is eliminated.
• c. more dopamine when giving voluntarily than taxed.

• In the end, Sapolsky thinks empathy is still a puzzling product of evolution. Altruism and reciprocity are linked however, so maybe we should stop scratching our heads about "pure altruism".
• Seems to endorse the idea that altruism (compassionate empathy) is trainable -- like potty training, riding a bike, telling the truth! So don't forget your workouts at empathy gym!
