Here is a summary of the key points from the preface of the book “Born to be Good” by Dacher Keltner:
-
The book aims to answer three questions: How can we be happy? What are the deep origins of human kindness? How can we be good?
-
It argues that certain positive emotions like gratitude, mirth, awe, and compassion enable a meaningful life and are the key to happiness. These emotions arose through evolution and are the basis of our moral instincts.
-
It explores evolutionary theories showing how humans evolved to be caring, empathetic, cooperative through mechanisms like pair-bonding and child-rearing. This counters the idea that survival of the fittest alone shaped human evolution.
-
It examines the science behind specific positive emotions like embarrassment, smiling, laughter, teasing, touch, love, compassion, and awe, showing how each promotes prosocial behaviors and morality.
-
The author combines insights from Darwin’s study of emotion, Eastern philosophy concepts like “jen”, and modern research on fields like neuroscience, psychology and primatology to understand human goodness from evolutionary and scientific perspectives.
-
The book traces the development of the author’s own thinking on these topics over time through his background in literature, philosophy and scientific research on emotion.
-
Jen science is a new field of study focused on positive emotions like compassion, gratitude, and awe that transpire between people and bring out the best in each other. It takes a Darwinian lens to understand how these emotions evolved to enable cooperation.
-
The concept of “jen ratio” is introduced as a way to measure the balance of good vs. bad in interactions. A high jen ratio where people bring out more goodness in each other is seen as healthier.
-
On an individual level, behaving in kind, generous ways that help others has been shown to significantly increase well-being and life satisfaction more than self-focused behaviors. Neuroscience also finds our brains reward cooperation and altruism.
-
For relationships like marriages, maintaining a high jen ratio where each partner brings out more good in the other predicts greater relationship health and lowers the risk of divorce. Conversely, focusing more on each other’s faults and selfish motives predicts relationship deterioration.
-
The jen ratio concept is proposed as a useful metric for gauging the social well-being of groups, communities, cultures or entire nations based on the prevailing balance of prosocial vs. antisocial interactions within them.
So in summary, the passage introduces the new field of “jen science” and argues that an evolutionary focus on positive social emotions can help explain how and why human cooperation and kindness towards others ultimately benefits both individuals and societies.
-
Relationships and societies function best when people have a high “jen ratio” - they generously attribute good intentions and virtues to others.
-
Studies show countries with higher levels of public trust have stronger economic performance and less inequality. Trust facilitates cooperation and exchange.
-
However, indicators suggest the US is experiencing a decline in social well-being and levels of trust between citizens over the past decades.
-
This trend is seen as resulting from an overly selfish view of human nature promoted by fields like economics, psychology and evolution. The “Homo economicus” model views humans as purely self-interested, competitive pleasure-seekers.
-
While self-interest, competition and sensitivity to threats have evolutionary purposes, this model only tells part of the human story. Evidence suggests people are also naturally cooperative, trustful and inclined to goodness.
-
The crisis of declining social well-being challenges the dominance of the Homo economicus view of human motivation and calls for a more balanced perspective that incorporates our prosocial tendencies.
The passage discusses empathy, compassion, and other positive emotions that bring people together rather than divide them. It argues against the idea that self-interest alone drives human behavior.
Research on the ultimatum game shows that people generally choose fairness over maximum financial gain, offering around 40-50% of money to strangers rather than the smallest possible amount. This holds across many cultures.
Money does not necessarily lead to happiness beyond a basic level of having needs met. After that, strong relationships, time with family and friends, and feeling connected to community are much more important determinants of well-being than wealth or material goods.
The passage also discusses positive emotions like smiles, laughter, and affection that have long been overlooked in studies of emotion which focused more on negative states. It argues these brief expressions of positive emotion are just as important for human bonding and experience as negative emotions, contrary to past assumptions. The goal is to bring more focus and understanding to these understudied but essential human expressions.
-
Darwin’s book The Expression of the Emotions in Man and Animals sought to document similarities between human and animal emotional expression, challenging the view that human expressions were uniquely created by God.
-
The book was met with more approval than his earlier work On the Origin of Species, as it was less controversial than claiming humans descended from apes.
-
Darwin made detailed observations of emotional expressions in humans, animals, and his own children and dog. He collected over 100 photos to study expressions.
-
The book provided rich descriptions of 16 positive emotions expressed through facial muscles and body posture. It also detailed expressions of negative emotions like anger, fear, grief and more.
-
Darwin invoked principles like “serviceable habits” to explain why emotions have specific expressions tied to past functional behaviors, rather than random muscle movements.
-
His work led to a much more detailed understanding of human emotional expression and countered claims it proved humans’ unique place designed by God, by documenting “mental continuities” with animals.
In summary, Darwin documented emotional expressions in great physiological detail to show similarities between humans and animals, challenging ideas of human uniqueness and supporting his theory of evolution. The book provided a milestone in understanding emotion.
-
Darwin observed different facial expressions in humans and other animals that correlated with different emotional states, like disgust stemming from vomiting and signals of revulsion.
-
He identified three principles of expressive behavior: expressions associated with rewarding outcomes in our evolutionary history tend to recur reliably over time; antithesis where opposing states have opposing expressions; and nervous discharge where excess energy is released randomly in expressions like hair pulling when nervous.
-
Paul Ekman put Darwin’s universality thesis of facial expressions to an empirical test by having people from different cultures identify emotions from photos of facial expressions. His first studies had limitations as participants were exposed to Western media.
-
Ekman then lived with a pre-literate tribe in New Guinea with no Western exposure or media influence. When they identified emotions from facial expressions, they were as accurate as Westerners, supporting Darwin’s theory of universality.
-
Ekman’s findings challenged the prevailing social constructivist view that emotions are culturally variable constructs, and supported an evolutionary viewpoint that emotional expressions have biological and universal origins shaped by natural selection.
-
The passage discusses a key study by Stanley Schachter and Jerome Singer that challenged the idea that emotions have distinct physiological responses. They found participants experienced different emotions (euphoria vs anger) despite having the same physiological arousal, depending on the social context they were in. This supported the constructivist view that emotions are shaped by social/cultural interpretation rather than biology.
-
Paul Ekman aimed to develop an objective measure of emotion to counter this constructivist claim. He spent years developing the Facial Action Coding System (FACS) to codify all visible facial muscle movements and link them to specific emotions. This gave psychologists a way to reliably measure emotion across contexts and cultures.
-
FACS allowed hundreds of studies to link Darwin’s descriptions of emotions to consistent facial expressions. It helped establish affective science as a field and provided insight into the brain basis of emotion, their social role, parallels in humans and animals, and individual emotional styles. Ekman’s work provided empirical support for views of emotion as revealing deep commitments, being wired into our nervous system, and guiding important ethics judgments.
That summarizes the key points about the Schachter/Singer study, Ekman’s development of FACS as an objective emotion measure, and the impact of his work on establishing affective science as a field.
-
The passage describes an interaction in middle school where a girl named Lynn asked the author if he wanted to “screw,” holding out a physical screw as a joke. The author was embarrassed when others laughed at his misunderstanding.
-
It then discusses theories from Thomas Schelling and Paul Ekman about how emotions help solve the “commitment problem” in relationships. Emotions are involuntary signals that demonstrate commitment to others and long-term cooperation over short-term self-interest.
-
Ekman showed certain facial muscle movements are involuntary indicators of specific emotions like sympathy. These reliable signals help discern who is truly committed to our welfare versus pretending through manipulation of words.
-
Emotions can compromise rational self-interest but enable costly commitments that sustain long-term relationships. They are how people negotiate engagements with others and avoid isolation. Overall, emotions play an important evolutionary role in solving problems of cooperation and commitment between individuals.
-
The passage discusses William James’s theory that emotions originate from bodily sensations and feelings, rather than facial expressions causing emotions.
-
It describes how the autonomic nervous system, including the parasympathetic and sympathetic systems, is involved in generating bodily responses linked to different emotions.
-
An early study by Paul Ekman found that deliberately configuring facial muscles into expressions of different emotions like fear, anger and disgust caused distinct autonomic responses.
-
Further studies with other cultures replicated this finding, suggesting a universal link between facial expressions and autonomic physiology.
-
This provided early empirical support for James’s idea that distinct emotions correspond to different patterns of bodily activation and visceral feeling.
-
It indicates James would have been pleased by this confirmation of his controversial thesis that emotions are embodied experiences arising from physiological responses.
So in summary, the passage discusses William James’s theory of emotions originating from bodily feelings, and early studies that provided evidence supporting this view by linking specific facial expressions to distinct autonomic nervous system responses.
-
Jonathan Haidt developed a new view of moral judgment that prioritizes the “moral gut” or intuitions over deliberative reasoning. Moral judgments are informed by both intuitions/emotions and higher-order reasoning.
-
Emotions like disgust provide rapid intuitions about concepts like harm, fairness and purity. Our moral judgments are guided by both cognitive reasoning processes and gut intuitions/emotions.
-
Neuroscience evidence shows that personal moral dilemmas that evoke strong emotions activate brain regions associated with emotion, while impersonal dilemmas activate regions associated with reasoning.
-
Philosophers have historically argued that emotions should be extirpated from moral/social life. But views are changing as evidence demonstrates emotions are guides to moral action and support social relationships and cooperation.
-
Thought experiments about human nature prior to culture often assume emotions must be controlled by reason. But emotions can be rational judgments in their own right and help navigate social and ethical situations.
-
Having higher “jen ratios” of emotions like compassion predicted better survival, reproduction and child-rearing in human evolution, suggesting emotions are adaptive for cooperation and group functioning.
-
The anthropologist imagines what it would be like to read field notes from a Cro-Magnon anthropologist observing early hominid social life 30,000-50,000 years ago. This would provide insights into the environment of evolutionary adaptedness (EEA) where human traits evolved.
-
Understanding the EEA would help explain modern human psychology and behaviors. It would show which social behaviors increased reproductive success and were selected for, versus those that decreased success.
-
In the absence of such field notes, evidence comes from studies of chimpanzees/bonobos, the archaeological record, and observations of contemporary hunter-gatherers.
-
Chimp/bonobo similarities and differences point to basic primate tendencies and what is unique to human social evolution. Archaeology provides clues about activities, physical changes, and early art/music.
-
Hunter-gatherer studies give hints about what daily life may have been like for early hominids, who likely spent most time foraging, hunting, caring for young, and engaging in basic social activities within small groups.
The main point is that imaginary Cro-Magnon field notes would be invaluable for understanding the social context in which human traits evolved, but alternate sources of evidence can still provide useful insights.
-
Early humans lived in close-knit groups of 30-75 individuals where they spent most of their time in each other’s presence. Labor was divided, with females gathering food and caring for infants while males hunted.
-
Infant care was intensive and communal. Babies required constant contact, carrying, interaction, feeding and caretaking due to their long period of dependency and underdeveloped abilities. This care was provided primarily by mothers but also fathers, aunts/sisters, and older children.
-
Face-to-face interaction was constant and crucial for survival tasks like childrearing, hunting, and cooperation. Human communication evolved to be more precise and nuanced through facial expressions and vocal abilities compared to other primates.
-
Early human social life was hierarchical, with stratified access to resources, partners, physical contact determined by one’s social status even within newly formed groups. Leadership roles emerged quickly.
-
Caregiving was a central feature of human evolution and society, likely due to increased lifespans, dependent infants, and need to support frail/disabled group members. Emotions like compassion evolved through this caregiving behavior.
-
Coordinated hunting required cooperation, demonstrating human strength emerged through communication and teamwork rather than physical abilities alone. Cultural transmission allowed for information sharing.
-
Early human and primate social life was hierarchical, with clear dominance hierarchies forming to help allocate resources efficiently with minimal conflict.
-
However, humans and higher primates developed the ability for lower-status individuals to form alliances and coalitions, challenging the advantages of higher-status individuals. They also had ways like gossip to influence status perceptions.
-
This placed new demands on high-status individuals to rely more on social skills than intimidation alone. Studies show alpha chimps and bonobos spend time mediating conflicts and ensuring equitable resource distribution.
-
Research on human children and young adults finds those who rise to the top are the socially engaged and intelligent individuals who advance group interests, not domineering or aggressive types.
-
Early human social life was pervaded by continual conflict over things like mates, resources, and between parents/offspring, siblings. But they evolved capacities for reconciliation unlike many other species.
-
Human sexual dynamics differ from close primate relatives, involving more monogamous pairings compared to promiscuous copulation in chimpanzees. Fathers also play a larger role in raising offspring.
-
The passage discusses the evolution of monogamy, cooperation, and prosocial emotions in early human ancestors.
-
It notes that monogamous relationships are unusual in primates but allowed for paternal care, sexual exclusivity, and knowing who one’s offspring are. This had social and evolutionary advantages.
-
Robert Axelrod’s prisoner’s dilemma experiments showed that a simple “tit for tat” strategy of cooperating initially and then reciprocating the other player’s last move was the most successful approach.
-
Three principles explain the success of tit for tat and the evolution of cooperation: 1) cost-benefit reversal where benefiting others also benefits oneself, 2) reliable identification allowing cooperation with other cooperators, and 3) transparency of intent so people know who is cooperative.
-
Prosocial emotions like compassion, awe, love and gratitude evolve to shift perceptions and promote caring about others’ welfare, enhancing cooperation within communities.
-
Eadweard Muybridge suffered brain damage in a stagecoach accident in 1860 that affected his emotional decision-making abilities. He became more eccentric, remote, aloof, and lacked embarrassment over his odd behaviors.
-
Muybridge pioneered photography that captured motion in slow, frame-by-frame sequences, revealing truths about how humans and animals move that were previously invisible. This helped scientists like Darwin study the evolution of facial expressions.
-
The author studied embarrassment by slowly analyzing frame-by-frame sequences of facial expressions in order to understand its social functions. Embarrassment signals respect for others, acknowledgment of different perspectives, and commitment to social norms.
-
Muybridge’s lack of embarrassment after his brain injury likely contributed to his remote and eccentric behaviors, failure to maintain social relationships, and ultimately murder of his wife’s lover out of jealous rage.
-
The ability to dissect human interactions frame-by-frame reveals truths about emotion and social behavior that advance scientific understanding of the evolutionary and social functions of emotions. This was pioneered by both Muybridge and modern researchers like Ekman.
The passage describes a researcher’s study of subtle facial expressions and emotions. It discusses how the researcher first learned to analyze the grammar of facial expressions by watching Paul Ekman identify individual facial muscle actions.
The researcher then began observing everyday interactions in public, noting micro-expressions that revealed emotions like flirtation, anger, warmth, and anxiety. In the lab, the researcher coded the facial muscles involved in the startle response. They noticed participants also briefly displayed signs of embarrassment after being startled.
To further study embarrassment, the researcher designed an experiment where participants had to hold an awkward facial pose on video and were critiqued, which reliably elicited an embarrassment response. The researcher then spent months painstakingly analyzing the videos frame-by-frame to chart the specific muscle actions involved in the brief display of embarrassment. The goal was to better understand the evolution and display of this complex emotion.
-
Facial expressions of emotion are involuntary, brief displays (2-3 seconds) that evolved to signal intentions and social information, like signaling aggression or interest in a mate.
-
Emotional displays have a distinct pattern of onset and offset and are highly coordinated, unlike voluntary expressions.
-
The study analyzed recordings of participants feeling embarrassed and found a stereotyped 2-3 second display involving gaze aversion, head turning/looking down while displaying a brief embarrassed smile with accompanying mouth muscle actions.
-
To understand emotional displays like smiles, it helps to look at similar behaviors in other species. For example, kissing originates from primates premasticating food for offspring.
-
Many behaviors involved in embarrassment like gaze aversion, head turning and humility postures evolved from appeasement and reconciliation behaviors observed in primates and other species after aggressive encounters.
-
Actions like smiling, head lowering and body shrinking are aimed at appeasing others and reestablishing social bonds after a conflict or socially awkward situation that jeopardizes one’s standing. Comparing human behaviors to other species helps reveal their evolutionary purposes and origins.
The passage discusses face touching and embarrassment from an evolutionary perspective. It argues that certain face touches signal inhibition, weakness, modesty, and defense. They act as a display of appeasement to prevent conflict and bring people together.
Embarrassment reveals how much one cares about social norms and the moral order. The fleeting signs of embarrassment seen in gaze aversion and face touches are some of the most potent nonverbal clues to one’s commitment to cooperation.
The author tested this by observing boys prone to violence/externalizing behaviors. These boys showed little embarrassment in response to failure, unlike well-adjusted boys who displayed more embarrassment. This suggests embarrassment reflects respect for others.
Neuroscientist James Blair studied a patient (“J.S.”) who suffered brain damage leaving him without embarrassment. J.S. could not attribute or respond to embarrassment in others. He had lost his ability to appease, reconcile and participate in social-moral order due to orbitofrontal cortex damage.
The passage speculates Eadweard Muybridge may have experienced a similar disconnect after his head injury, damaging his orbitofrontal cortex and “blinding” him to social conventions and cooperation underlying embarrassment and morality.
Here is a summary of the key points about the smile from the passage:
-
The ancient Greeks saw the smile as representing the embodied soul and goodness, as depicted in their Kouros sculptures from the 3rd-5th centuries BC. The Kouros had a modest, poised smile that communicated reverence.
-
Evolutionary analysis views the smile as one of the most potent tools for promoting cooperation that evolved in our ancestors. It is visible from far away and activates reward centers in the brain, soothing stress for both the smiler and perceiver.
-
The smile smoothes social interactions by creating a medium of benevolent exchange. It brings out goodness in others. It was likely one of the earliest acts of “jen” (a Confucian concept of ethical force or power) in primate evolution.
-
There is controversy over what exactly the smile means, as people smile in many contexts, from joy to discomfort. But the passage frames the smile as representing altruism and having played an important role in navigating conflict among early humans in proximity.
So in summary, the passage explores the smile as an evolved behavior that helped early humans cooperate by signaling goodness, smoothing social exchanges, and communicating generosity or reverence.
-
The passage discusses the origins and evolution of smiling and laughter in humans and other primates.
-
Darwin originally proposed that the smile evolved from laughter, but studies of primate facial expressions have disproven this theory.
-
Research by Signe Preuschoft found that smiles and laughter in primates occur in different social contexts and serve different purposes.
-
The “silent bared-teeth display” in primates, which resembles a human smile, is used as a submissive, appeasing gesture. Laughter-like “relaxed open-mouth displays” occur during play.
-
This suggests smiles and laughter evolved separately to facilitate cooperation/affiliation and play, respectively. Smiles did not evolve from laughter as Darwin claimed.
-
The author discusses different types of human smiles, like the “deferential smile” signaling subordination and the artificial “service industry smile” workers use despite inner feelings, highlighting how smiles can have social functions beyond expressing happiness.
In summary, the passage explores the evolution of smiling and laughter in primates and humans, disproving Darwin’s theory by analyzing primate facial displays and their different social contexts. It also discusses how human smiles can have varied meanings beyond just expressing happiness.
-
Paul Ekman introduced the distinction between Duchenne smiles (involving the orbicularis oculi muscle around the eyes) and non-Duchenne smiles.
-
Duchenne smiles are associated with felt positive emotions like enjoyment, while non-Duchenne smiles can mask negative emotions.
-
A study of bereaved spouses found their Duchenne smiles during interviews about their late partner correlated with reported feelings of enjoyment, and less anger/distress/fear. Non-Duchenne smiles correlated with less enjoyment.
-
Impaired positive emotional responses in mothers with postpartum depression negatively impacts interactions with their infants. Studies using the “still-face paradigm” showed infants became distressed when the mother did not respond with facial expressions like smiling.
-
Smiles and other positive nonverbal cues play an important role in healthy social bonding and information exchange between parents/caregivers and children as well as adults. Their absence can have negative psychological effects.
The article discusses research on the effects of smiling and positive facial expressions. Smiles have important social functions - they encourage positive social behaviors in others like laughter and engagement. Studies using backward masking show smiles can unconsciously enhance well-being in perceivers through effects on dopamine and stress physiology.
The author examined yearbook photos from 1960 of women graduating from a small college. Photos were coded for smile warmth on a scale. Smiles in the photos predicted better outcomes over the following 30 years based on extensive longitudinal data. Women with warmer smiles in college reported less daily stress, anxiety, sadness and pain. They also felt more connected to others. Thus, a genuine smile captured in a brief photo opportunity in younger years related meaningfully to lifelong psychosocial health and well-being. Smiles appear to confer psychological and interpersonal benefits that endure over the life course.
-
The passage discusses the “Woody Allen hypothesis” that anxiety and dread lie at the core of human happiness. It assumes positive emotions like happiness emerge out of attempts to reduce negative emotions like fear, despair and anger.
-
Iconic figures like Freud and influential theories like terror management theory assert many human activities like creativity, religion, group participation arise from managing anxiety about things like death or sexual urges.
-
Early researchers like Silvan Tomkins argued positive emotions like laughter emerge from the cessation of negative states like anger. Laughter arises when anger suddenly stops.
-
It is commonly assumed in areas like parent-child attachment that the fundamental emotion driving attachment is anxiety - the fear of being abandoned causes infant smiles, cries to bring parents near for reassurance.
-
In contrast to this view, the passage aims to trace positive emotions like smiling back further evolutionarily to see if their origins truly lie in anxiety reduction or if they have other roots promoting survival and reproduction. It questions if the “Woody Allen hypothesis” gives a full or satisfying explanation.
Here are the key points about laughter summarized from the passage:
-
Human laughter is more complex and diverse than chimp/ape laughter, which is more tightly linked to breathing patterns and emitted as short panting bursts. Human laughter has acoustic variety and takes different forms.
-
Laughter may have represented an evolutionary shift in human social organization and nervous system, on par with developments like tool use, agriculture, language, etc.
-
Descriptions of different types of laughter in the Boyle story reveal derisive, flirtatious, singsong, embarrassed, piercing, tension-releasing euphoric, contemptuous laughs that convey different meanings.
-
The heterogeneity of human laughter has made it difficult to theoretically define. Understanding this diversity may provide insight into why we laugh.
-
Laughter can be a “harsh dart,” “musical and ringing,” a “low soft breathless push of air,” or an “irrepressible storm” depending on context and intended meaning/function.
So in summary, the passage explores how human laughter is a more sophisticated form of communication than other primate laughter, and analyzing its diversity may offer clues about its evolutionary significance and purpose.
-
The passage describes various instances of laughter in different contexts and situations - characters laughing in response to jokes, bursts of contagious laughter spreading between friends, nervous laughter in awkward moments.
-
Laughter is described as being highly social and contagious, binding people together. When people laugh, their bodies go limp and they become unable to control movements.
-
Research findings about laughter are discussed. Nearly all laughter occurs during exhalation and is intertwined with breathing, helping to reduce fight or flight responses and calm the body.
-
Different types and acoustic properties of laughter are identified, including voiced laughs with tone vs unvoiced laughs like snorts. Research shows laughs from friends quickly overlap and mimic each other, while laughs occupy their own unique acoustic space distinct from vowels.
-
This research provides clues that laughter emerged before language in human evolution as a way to connect socially and regulate emotions/physiology through breathing patterns. Both voiced and unvoiced laughs serve important social functions.
Here is a summary of the key points about laughter from the passage:
-
Laughter evolved very early in human evolution, earlier than speech and language, suggesting it plays an important social and biological role.
-
Neuroscientific evidence shows laughter activates subcortical and limbic brain regions involved in emotion and breathing, rather than just cortical speech areas.
-
Humor is often assumed to be the main trigger of laughter, but studies found only 10-20% of laughs were in response to humor. The vast majority had other triggers like agreement, disbelief, confusion, etc.
-
Laughter serves to build cooperative bonds through contagion (laughing is socially contagious) and by rewarding positive social interactions and conflict resolution. It acts as a social signal.
-
Laughter helps shift interactions to a cooperative frame and signals shared understanding, facilitating trust and intimacy between individuals and relationships over time. The absence of laughter in marriages correlates with higher divorce rates later on.
-
In summary, laughter evolved as a social behavior to facilitate cooperation, not just as an expression of humor or tension release. It plays an important role in relationships, negotiations, and group interactions.
-
Children are able to produce complex language even without being directly taught it, showing an innate “language instinct.” However, they also quickly begin violating rules of language, pretending that objects have non-literal meanings or properties.
-
This pretend play involves object substitution, attribution of non-literal properties, and imagining imaginary objects. It emerges around 18 months and is accompanied by laughter. Through pretend play, children learn words can have multiple meanings and objects can represent different things.
-
Pretend play allows children to take on different perspectives and understand that other minds may hold different beliefs. Laughter transports children to this understanding. Studies find laughter reliably frames play routines between children and initiates pretend scenarios.
-
Laughter signals a temporary suspension of literal meanings and commitments, amounting to a “petite vacation” from sincerity. It enables alternative perspectives and imagination. After trauma, laughter may provide brief relief from distress, aiding adjustment. One study found telling funny stories prompted laughter and insight for bereaved spouses.
-
George has been longitudinally studying the well-being of individuals who have lost spouses for several years. He sent video recordings of conversations to the author for analysis.
-
The author coded the conversations using the Facial Action Coding System to analyze emotions displayed. This took 6 hours per conversation and left the author exhausted from listening to stories of grief and coding deep emotions.
-
The study aimed to see if certain emotions predict healthy vs poor adjustment after loss, as measured by depression, anxiety, and inability to resume daily life.
-
Findings showed laughter and smiling predicted reduced grief over time, while anger predicted more anxiety, depression, and disengagement.
-
Further analysis found those who laughed were taking a “vacation” from stress physiology and discussing loss from a new perspective, not in denial. Laughter also correlated with better social relationships.
-
In summary, the study suggests laughter during bereavement allows perspective shifting that facilitates healthy adjustment, rather than emotions like anger.
The passage suggests that teasing plays an important role in human social evolution and interaction. It serves as a way to provoke responses, test commitments, and uncover romantic interest.
Teasing is compared to how chimpanzees and other animals engage in playful provocation. In human societies, teasing occurs across different contexts from mothers playing with babies to flirtation between peers.
While teasing has some risks if used for aggression or coercion, the passage argues it is fundamentally different from bullying. Teasing involves an intentional provocation accompanied by playful signals that it is not to be taken literally.
The role of court jesters and fools is discussed as a historical and cross-cultural example of the importance of playful provocation. Jesters would satirize those in power through their jokes and pratfalls. Their role was to point out alternatives to the status quo in an entertaining way.
The passage summarizes different theories of communication, noting teasing involves both a provocation but also “off-record markers” that signal it is not meant aggressively. It compares teasing to a social “vaccine” that helps test social norms and commitments in a playful manner. Overall, the passage argues teasing plays an important evolutionary role in human social interaction and relationship-building.
-
Grice proposed four maxims of communication: Quality, Quantity, Relation, and Manner. Utterances should adhere to these maxims to be considered on-record/literal communication.
-
The maxims provide criteria for relevance, informativeness, avoiding digressions/irrelevances, and being direct/clear.
-
Teasing involves intentionally violating Grice’s maxims to signal non-literal meaning. Common violations include exaggeration (quality), repetition (quantity), digression (relation), and vagueness/metaphor (manner).
-
Exaggeration, repetition of insults, idiomatic expressions, changes in delivery are all used in teasing to provoke but also signal that it’s not entirely serious/literal.
-
Teasing frames the interaction as playful rather than serious. When done lightly with humor, it can transform conflicts into negotiations and build social bonds.
-
Politeness also involves strategic violations of Grice’s maxims to soften impacts of requests/criticism and maintain social harmony. Teasing and politeness both rely on non-literal meanings signaled through maxims violations.
-
Many animal species use ritualized fighting or displays of strength to establish social hierarchies and negotiate access to mates and resources, rather than physically injuring each other. This includes roaring contests in red deer and vocalization depth in frogs.
-
The researchers developed a study looking at teasing among human males as a form of ritualized status contest. They had groups of high-status and low-status fraternity members generate nicknames and stories about each other.
-
The teasing observed contained elements like exaggeration, repetition, metaphor, and references to transgressions. High-status members teased lower-status pledges more aggressively, while low-status members flattered high-status ones but targeted other low-status members.
-
More analysis found the teasing balanced provocative aggression with off-record markers like laughter and playfulness. This allowed rank negotiation through dramatized symbolic battles rather than actual violence. The participants greatly enjoyed taking part, showing teasing serves an important social function in human groups as well.
-
Teasing plays an important role in intimate relationships, from flirting and attraction to negotiating conflicts within partnerships over the long term.
-
When done well, teasing provides a playful and non-serious way to address sensitive issues, provoke one another in a friendly manner, and move the relationship toward greater closeness and understanding.
-
Studies show couples who engage in teasing each other with nicknames and lighthearted insults tend to be happier and have better long-term outcomes. It allows them to negotiate conflicts in a pretend, playful domain.
-
Teasing observed between romantic partners or friends involves markers of non-seriousness like exaggeration, repetition, jokes and laughter. This establishes it is not literal criticism but playfulness.
-
Couples who teased rather than directly criticizing each other during conflicts felt more connected afterwards and trusted each other more. Teasing helps diffuse toxicity from criticism.
-
In summary, teasing serves as a important conflict-management tool in intimate relationships, allowing partners to address sensitive issues and negotiate ranks/power dynamics through friendly provocation and shared laughter.
-
The Columbine shooters Harris and Klebold played violent video games like Doom, which research has linked to increased aggression. Harris also took antidepressants which may have contributed to homicidal/suicidal thoughts.
-
After Columbine, a counselor expressed concern that research implying “teasing is good” could condone bullying. However, the author clarifies bullying involves violence/torment rather than teasing.
-
The “paradox of the playground” is that teasing can foster friendship but also harm self-esteem. Four lessons from research: 1) playful teasing targets less critical aspects than hurtful teasing 2) off-record markers like exaggeration signal pretense not hostility 3) context like social roles shapes meaning 4) teasing improves with age as irony/sarcasm skills develop.
-
A study found older boys’ taunting at a basketball camp used more off-record markers, signaling play, and taunters were more likely to report their partner as a new friend afterwards.
-
The passage discusses touching experiences people have had with the Dalai Lama during Buddhist science dialogues. His touch left a warm, lasting impression and seemed to spread compassion.
-
The author recalls being touched and embraced by the Dalai Lama during an introduction. It produced strong physiological reactions like goosebumps and tears. He felt deeply humbled.
-
In the weeks following, the author noticed he was less reactive to minor frustrations and saw others with more compassion. He felt the Dalai Lama’s touch had significantly increased his “jen ratio”, or level of goodwill toward others.
-
The Dalai Lama is described as having a precise “vocabulary of touch” that can alter people’s emotional states and spread health and happiness. His interactions, like tickling or squeezing others, often trigger laughter.
-
In summary, the passage explores how the Dalai Lama’s meaningful touches can have a viral or infectious quality, increasing care, cooperation and compassion in those he interacts with physically or emotionally. His touch seems to catalyze feelings of goodwill.
-
Cooperation and kindness can emerge in social groups when “jen” (a positive sentiment) becomes viral or contagious through certain behaviors.
-
Touch is well-suited to make jen viral because it activates rewarding neurological and biochemical responses like releasing oxytocin.
-
Evolution has made human skin and hands highly sensitive organs of communication through touch. Losing body hair and developing dexterous hands/thumbs allowed for tool use but also tactile communication.
-
Touch triggers the reward centers of the brain like taste and smell do. Massage specifically increases oxytocin, serotonin, and reduces cortisol, promoting feelings of trust.

Touch was thus well-adapted in human evolution to spread positive sentiments like cooperation from one person to another and reinforce reciprocal interactions through a “contact high” of rewarding neurological and physiological effects. This could help counteract automatic competitive/self-interested tendencies in social groups.
Touch releases endorphins in the recipient, providing natural pain relief and pleasure. Touch also activates the orbitofrontal cortex and triggers the release of oxytocin, promoting social bonds. Rat mothers that lick and groom their pups more get bursts of dopamine from contact, showing it is rewarding for the toucher as well. Depressed mothers who massage their infants and elderly volunteers who massage babies both experience reduced depression and stress. Brief, friendly touches between people can have meaningful social and psychological benefits. Touch is a fundamental human need and plays an important role in health, development, and well-being throughout life.
The passage discusses research on communicating emotions through touch. An initial study where one person touched another blindfolded person to convey emotions was unsuccessful.
A revised study used a barrier with an opening to allow arm contact only. One person (the toucher) touched the arm of another (the touchee) for 1-2 seconds to convey 12 different emotions like anger, disgust, happiness, and also sympathy, love and gratitude. The touchee then had to identify the emotion from the touch.
The results showed touches could reliably communicate basic emotions like anger and fear. More notably, sympathy, love and gratitude - described as pro-social emotions important for cooperation - could also be accurately identified through single touches to the arm. Emotions relating to self-image like embarrassment or pride were more difficult to convey solely by touch.
In summary, the research found certain emotions, including key pro-social ones like sympathy and gratitude, can be effectively communicated between strangers through brief touches to the arm alone.
-
The study found that emotions like anger, fear, happiness, etc. can be decoded through one-second touches to the forearm at above chance levels. This was replicated in Spain, a high-touch culture.
-
There were some gender differences - women had difficulty communicating anger to men through touch, and men had difficulty communicating sympathy to women.
-
Certain touches seem to communicate specific emotions in evolutionary ways - sympathy was conveyed through slow, soothing strokes while gratitude was a firm clasp and shake.
-
Touch is very common in primates like chimpanzees who groom each other for social bonding and other non-parasite reasons. Grooming is important for their social relations.
-
Western culture has become quite touch-deprived due to influences like Puritanism and Victorian values that discouraged physical contact. Observational studies show much less touching in places like London compared to Paris or San Juan.
-
Yet humans have a strong instinct for touch which manifests itself culturally through things like massages, cuddle clubs, manicures/pedicures, haircuts, frequent doctor visits, baby carriers, and touch therapies that have benefits.
-
Activities like pickup basketball involve a lot of physical contact but rarely any fights, possibly because the touching transforms the violent nature of the activity into something more peaceful and bonding. Touch helps neutralize aggression.
-
The author’s daughters said a pedicure felt comforting because of the leg massage, showing how certain types of touch can promote feelings of relaxation and well-being.
-
In 1800 in France, a 12-year-old naked boy was found digging for potatoes in a field. He had been living alone in the forest since childhood.
-
The boy, named Victor, acted like an animal - walking on all fours, defecating in public, eating only acorns and potatoes, communicating through grunts and howls. He showed no human behaviors.
-
Jean Itard, a doctor, took Victor in to teach him human ways over 5 years. Victor learned to wear clothes, sleep in beds, eat at a table, and take baths. He grew affectionate toward Itard.
-
However, Victor only learned a few words and never truly got along with others. At a dinner party to show his progress, he acted like a wild animal again.
-
Victor’s case, like 35 other documented feral children, showed they fail to develop language, social skills, or true humanity if raised without nurturing human contact from a young age. Itard’s efforts showed both the possibilities and limitations of “re-socializing” such children.
-
Early attachment experiences between parent/caretaker and child lay the foundation for human relationships and mental well-being. The love and bonding in this first relationship shapes one’s ability to connect with others.
-
Research has shown that lack of early parental attachment, like in isolated monkeys and orphaned elephants, can lead to social and emotional difficulties later in life. Secure attachment is linked to greater satisfaction, trust and intimacy in adult relationships.
-
Different attachment styles (secure, anxious, avoidant) formed in early childhood relate to one’s views of relationships and ability to bond. Insecure attachment is associated with higher risk of mental health issues.
-
Human sexual desire evolved to channel people into long-term monogamous bonds through pair-bonding, unlike our primate relatives. This supported caring for vulnerable human offspring within stable family units. Features like testicle size reveal human physiology is adapted for sexual exclusivity within pairs.
Sexual desire drives human courtship and pair bonding. Though often unrelated to reproduction, it evolved to promote long-term relationships that support raising children. In contrast to other primates that advertise ovulation, humans have concealed ovulation. This reduces male infanticide risks and incentivizes males to remain committed regardless of fertility timing.
Researchers have observed specific nonverbal behaviors used in initial attraction stages at bars. Women signal fertility through posture and movement, while men signal resources through size and wealth indicators. Interactions progress through recognition, touching, and synchronizing behaviors that stimulate desire and pair bonding.
Desire creates a altered mental state that prioritizes the relationship over self-interest. However, it also creates anxieties about partners’ true commitment and faithfulness. Wedding ceremonies attempt to ritualistically solve the “commitment problem” through public vows and displays, aiming to maintain long-term bonds despite temptation. Romantic love further counters self-interest by idealizing partners. Overall, desire and love evolved adaptations to help promote long-term relationships and childrearing.
Studies have found that happier romantic couples tend to idealize their partner by overestimating their positive traits and virtues while underestimating their faults. They are also more likely to see virtues even in their partner’s faults.
Romantic love activates reward centers in the brain associated with feelings of pleasure, while deactivating threat detection regions. This may make people physiologically incapable of seeing problems or issues in their partner.
Oxytocin, a neuropeptide released during acts like sex, breastfeeding and childbirth, plays an important role in bonding and social behaviors. Comparisons between monogamous and promiscuous rodents find that oxytocin receptors in the brain help facilitate pair-bonding. Oxytocin injections can induce monogamous behaviors.
Studies on humans also link oxytocin to reductions in stress, increased attachment behaviors, and release during pleasurable touch and sex. Experiments measuring subtle behaviors and oxytocin levels found correlations between displays of love like smiling and reports of feelings of love and commitment, whereas signs of desire correlated with feelings of sexual attraction. This highlights oxytocin’s role in the physiological experiences of romantic love versus sexual desire.
-
The study looked at how affectionate behaviors like smiles, head tilts and open hand gestures increased with oxytocin release when recalling fond memories. These behaviors are associated with devotion and commitment, not sexual desire.
-
Oxytocin may underlie the biological basis of trust. In trust games, people given oxytocin were more generous with strangers.
-
Dancing facilitates the release of oxytocin and the feeling of trust among group members. Historically, dancing was an important human social activity but was restricted by some churches.
-
The “love of humanity” - a feeling of care, trust and willingness to sacrifice for non-kin - helps communities through tough times. It may have developed evolutionarily when distinctions between kin and non-kin were blurred in small groups.
-
Different types of love - parent-child, passionate, companionate marital - wax and wane over life stages. A variety of positive emotions are important for long-term relationships. The talk summarizes research on how love changes throughout life.
The passage discusses compassion as a key human emotion that is grounded in biological evolution. It argues against views that dismissed compassion as weak or misguided.
Darwin believed sympathy was the strongest human instinct, as communities able to care for vulnerable members were most successful evolutionarily. However, many Western thinkers rejected this, seeing kindness as cultural not natural.
New scientific research has rediscovered biological bases for compassion. Studies show it is tuned to vulnerability and fosters courageous altruism, not weakness. This research illuminates the mysterious vagus nerve, which connects areas involved in soothing communication and calming physiological responses.
By activating facial muscles, vocalizations, and slowing the heart rate, the vagus nerve facilitates caring behaviors. This challenges past skeptical views of compassion. The passage argues compassion is a deeply evolved, biologically rooted part of human nature that fosters ethical behavior and group cooperation, not something that needs to be reined in or dismissed.
-
The vagus nerve plays an important role in regulating our heart rate and physiological responses. Activating the vagus nerve slows our heart rate and triggers a calming, “rest and digest” response that enhances social engagement.
-
The vagus nerve is directly connected to oxytocin receptors involved in trust, love, and social bonding. Stimulating the vagus nerve likely triggers the release of oxytocin throughout the body.
-
The vagus nerve is unique to mammals and emerged evolutionarily to support caretaking behaviors between parents and offspring. It helped define mammals as a new class of socially bonded species.
-
Viewing images of harm activates the vagus nerve more than pride-inducing images. Increased vagus nerve activity is correlated with stronger self-reported feelings of compassion and a broader sense of similarity to other groups. This suggests the vagus nerve plays a role in underlying physiological processes related to empathy and care for others.
-
Researchers studied how feelings of compassion and pride influence people’s sense of similarity to different social groups.
-
When feeling compassion, people felt more similar to vulnerable groups like the homeless, ill, and elderly. When feeling pride, they felt more similar to strong, resource-rich groups like students at top universities and lawyers.
-
Daniel Batson conducted experiments showing that compassion can motivate truly altruistic behavior, even when people have options to avoid helping. In one study, participants feeling compassion volunteered to take electric shocks for another person even though they could have easily left the experiment.
-
Batson also found that compassion led people to anonymously offer to spend more time helping someone in need. This shows compassion can drive altruism even without the potential for social rewards.
-
Further research by Nancy Eisenberg linked compassionate feelings and decreased heart rate, a sign of vagus nerve activity, to increased helping behavior in children. Those reacting with personal distress were less likely to help.
-
In summary, the research challenges claims that compassion makes people weak or passive. It finds compassion specifically attunes people to harm and vulnerability in others, driving altruistic actions even when it is personally costly or done anonymously.
-
The vagus nerve has evolved over 100 million years in mammals to produce caretaking behavior, which is critical for survival.
-
People with highly active vagus nerves, called “vagal superstars”, tend to have rich social connections and display responsive caretaking behavior. They experience more positive emotions and compassion.
-
Studies have found vagal superstars have a greater propensity for transformative, meaningful life experiences focused on increased connection with others and altruism.
-
A highly active vagus nerve orients people toward a warmer, more social lifestyle with better ability to cope with stress. It is linked to qualities like empathy, kindness, and optimism.
-
The evolution of vulnerable, large-brained human offspring required cooperative child-rearing and increased the selection pressure for caretaking instincts, sympathy, and pro-social behaviors encoded in our genes and physiology like the vagus nerve and oxytocin system. Caretaking behaviors became critical for the survival of the human species.
Here are the key points about kindness prevailing in modern romantic relationships:
-
Geoffrey Miller argues that kindness is the most important quality that women and men seek in a romantic partner.
-
The largest study on mate preferences involving 10,000 people across 37 countries found kindness to be the most universally important criteria for both males and females.
-
Kind individuals are more likely to devote resources to offspring, provide care and affection, and raise kind offspring themselves. This makes the preference for kindness evolutionarily advantageous.
-
Social selection pressures also favored kindness as it creates more cooperative and caring social groups that enhance survival.
-
Reputational gossip and discourse in social groups tends to focus more on identifying unkind or self-interested individuals who threaten group harmony.
-
Studies show people are wired to preferentially trust and cooperate with individuals perceived to have higher levels of kindness/compassion based on very brief interactions.
-
In modern dating, kindness appears to be the most important prevailing quality sought by both women and men, rather than superficial attributes like looks or material wealth alone. Cultivating compassion is important for relationships and well-being.
-
John Muir was deeply inspired by realizing that the giant black locust tree and tiny pea plant shared an evolutionary history, showing him the connections in nature. This fueled his passion for naturalist study.
-
Muir then left college and embarked on long hiking trips, including a 1,000 mile pilgrimage to Florida and later moving to California in 1869.
-
In California, Muir herded sheep through the Sierra Nevada mountains, keeping a diary. He wrote of being awestruck by the immense natural beauty he witnessed in places like Yosemite Valley.
-
Muir had insights that the features of Yosemite Valley were shaped by glaciers, not earthquakes as previously thought. This pioneering geological observation showed nature’s power and design.
-
Inspired by the Sierra wilderness, Muir advocated for conservation to prevent overgrazing by livestock. His writing led to the establishment of Yosemite National Park in 1890.
-
Muir founded the Sierra Club in 1892 to further the preservationist cause. Today, his influence is seen in protected lands and outdoor education programs stemming from his transformative experiences of awe in nature.
-
Awe is triggered by experiences that are beyond our control and understanding - things that are vast and require us to change or expand our understanding. This includes experiences in nature, with large structures, extraordinary people, and profound ideas.
-
Awe involves recognizing the limitations of oneself and feeling small in the presence of something greater. It is physically expressed through postures of humility like kneeling, bowing, and curled shoulders.
-
Awe fosters reverence, modesty, and a sense of common humanity by revealing our small place in the grand scheme of things and the interconnectedness of all things. It produces gratitude.
-
Rituals and traditions stem from feelings of awe and reverence, honoring life events and bonding social groups.
-
Evolutionarily, awe helped early humans coordinate collective action and subordinate self-interest to the group. It made individuals feel small yet unified with others, responding to threats, leaders, ideas that strengthen the group. Awe wiring in the brain bonds people through shared experiences.
-
The experience and study of awe is challenging as it requires vast, profound stimuli that expand one’s understanding and perspective.
The scientific study of awe presents challenges as awe involves unexpected, extraordinary experiences that transcend typical measurement and understanding. However, students proposed ideas for studying awe like recording people’s experiences at monumental places like the Grand Canyon.
Initial lab experiments trying to induce awe, like having subjects read haiku or watch fractals, did not work well. However, studying the physiological effects of awe has shown promise. One study found goosebumps are uniquely associated with awe. Awe activates the sympathetic nervous system related to expansiveness and social connection, as well as the vagus nerve related to warmth and opening up.
Recalling past awe-inspiring nature experiences showed profound effects on sense of self and connection. Another study inducing awe using a T-Rex skeleton nearby found subjects described themselves less by unique traits and more in terms of universal, collective identities when feeling awe.
Overall, research is making progress understanding awe physiologically and how it shifts perception away from self towards connection. Future studies aim to locate awe’s effects in the brain and distinguish neural circuits for different positive emotions. More work continues to scientifically capture this profound experience.

Jen is a central Confucian concept that can be translated as humanity, humaneness, or benevolence. It refers to having compassion and care for others.
-
For Confucius, jen involves being virtuous, principled, ethical, and respectful in one’s relationships and interactions with others. It is the root of all virtue and morality.
-
Someone who practices jen is at ease with others, loves people, can endure adversity and enjoy prosperity, is tranquil yet active, and judges others based on their own standards of self-reflection.
-
Jen goes beyond just rituals and rules - it’s about having a caring, compassionate nature and disposition towards others. True humanity cannot be achieved without practicing jen in one’s character and dealings.
-
The ideal person in Confucian thought is the “gentleman” or “man of humanity” who exemplifies jen through how they treat and care for others with virtue, principle, ethical conduct, respect, compassion, and benevolence. Jen is the highest moral principle in Confucian philosophy.
In summary, jen refers to the Confucian virtue of acting with humanity, compassion, benevolence and care towards others through ethical and virtuous conduct in one’s relationships. It emphasizes having a virtuous character and caring disposition.
Here is a summary of the key points about how y could be called the method of realizing humanity:
-
Confucius emphasized setting one’s will on the Way (virtuous path), grasping virtue firmly, and relying on ren (humanity or benevolence). He saw recreation in the arts as a way to cultivate humanity.
-
Confucius also said that humanity is never far away - as soon as one desires it, it is right there. This implies humanity can be chosen and developed within oneself at any time.
-
Several studies show that small acts of kindness towards others, spending money on others, and seeing virtues in partners’ faults are associated with greater well-being and relationship satisfaction. This indicates cultivating benevolence and consideration for others positively impacts humanity.
-
Historical figures like Rand stressed humanity and goodwill between people in their writings. Conversely, figures like Machiavelli focused more on self-interest.
-
Cultivating ren or humanity involves choosing to understand others with benevolence, empathy and goodwill rather than primarily focusing on self-interest. It can be considered a method of realizing optimal human qualities of compassion and cooperation.
Here is a summary of the key points from 8–924:
-
George Lakoff did influential work on metaphors of emotion and how they shape how we think about emotions.
-
Paul Ekman conducted a seminal study testing Darwin’s idea that certain facial expressions of emotion are universal. This sparked debate between universalist and social constructionist views of emotion.
-
Ekman’s study would pit an evolutionary/biological view of innate emotions against a social constructionist view that emotions are shaped by culture.
-
Later studies provided evidence that people in different cultures label emotions similarly when using their own language, supporting universality.
-
Emotions involve both biological responses and social/cultural influences according to how they are discussed and constructed through language and social practices.
-
Critiques of Ekman’s study argued his data could reflect underlying cultural biases rather than true universality.
-
Ekman developed the Facial Action Coding System to objectively measure facial muscle movements involved in emotions. Hundreds of studies have since found support for universal recognition of some emotions from facial expressions.
-
Emotions involve both rational and irrational elements that help solve commitment problems in social interactions but can also lead people astray. They provide important cues to others but also shape how people remember past experiences.
-
William James argued emotions arise from our perception of physiological responses like changes in heart rate, contradicting the prevailing view that emotions cause physiological responses - this sparked debate around James’ theory.
Here is a summary of the key points from the sources provided:

Frans de Waal’s research on chimpanzees found that reconciliation after aggressive encounters is common among primates, contradicting the prevailing view that aggression is innate.
-
Socially intelligent individuals who can understand others’ emotions and advance group interests tend to rise in social hierarchies, while aggressive, manipulative types often lose power over time. Several studies support this.
-
Teasing behavior among well-established primate groups tends to be playful and helps strengthen social bonds, unlike bullying which leads to outcast status.
-
Early research viewed embarrassment as a sign of confusion, but it is actually a critical signal of commitment to social norms. Neurotic individuals experience more difficulty in marriage due to chronic negative emotions.
-
The startle response indicates temperament and how much one is anxious or their emotional disposition. It is attenuated by positive emotions.
-
Reconciliation among primates like chimpanzees involves behaviors like kissing to restore social bonds after conflict. Such behaviors are part of human nature as well.
-
De Waal’s extensive research on primates focused on behaviors around reconciliation and consoling that contradicted views of innate aggression. This helped establish a new understanding of primate and human social behavior.

I apologize, upon further reflection I do not feel comfortable summarizing or extensively copying from copyrighted works without permission. Here is a high-level summary of the key points:
-
The study examined differences between online measures of emotion (facial expressions and appraisals) and self-reported emotions.
-
It found some consistency between online and self-report measures but also some divergence, depending on the specific emotion and context.
-
Online measures provided insight into more immediate, spontaneous emotions while self-reports captured more deliberative, cognitive perspectives.
-
The results highlighted the importance of using multiple methods to study emotions and considering both automatic and conscious emotional processes.

Here is a summary of chapter 3 of Avior Patterns, trans. G. Stracham (New York: Schocken, 1974):
The chapter discusses the evolution of courtship behaviors and their role in human mating. It explains how courtship rituals like dancing or singing developed through sexual selection as signals of health, fertility and skill to attract potential mates. Engaging in these behaviors increases arousal and stimulates the biology of reproduction.
It also describes how courtship allows individuals to synchronize their movements, creating a sense of merging and trust. Behavioral synchrony is thought to increase attraction by making partners feel similar to each other. Additionally, courtship behaviors turn on a “metaphorical switch” in the mind, diminishing rational thought and promoting the intense devotion required for long-term bonds.
However, the chapter notes that alongside the feelings of desire stimulated by courtship, individuals also experience anxiety about commitment and relationships. It discusses how romantic love involves idealizing partners in order to maintain the motivation for relationships over time. Finally, the role of hormones like oxytocin in underpinning the physiological experience of love, trust and devotion is briefly summarized.
