Empathy Is a Clock That Ticks in the Consciousness of Another: The Science of How Our Social Interactions Shape Our Experience of Time

Empathy Is a Clock That Ticks in the Consciousness of Another: The Science of How Our Social Interactions Shape Our Experience of Time
// Brain Pickings

"We may be born alone, but childhood ends with a synchrony of clocks, as we lend ourselves fully to the contagion of time."

---

When I was growing up, my father — a kind man of quick intellect and encyclopedic knowledge about esoteric subjects — had, and still has, one habit that never failed to make other people uneasy and to infuriate my mother: In conversation, the interval of time that elapses between the other person's sentiment or question and my father's response greatly exceeds the average, a lapse swelling with Kierkegaard's assertion that "the moment is not properly an atom of time but an atom of eternity."
At first, one might suspect that my father is taking an incubatory pause to produce a considered response. But, soon, it becomes apparent that these disorienting durations have no correlation with the complexity of the question — even when asked something as simple as the time of day, he would often let miniature eternities pass and lasso the other person in anxiety as the contrast between the natural response time and my father's gapes its discomfiting abyss of ambiguity.
It turns out that my father's liberal pauses are so discomposing because our experience of time has a central social component — an internal clock inheres in our capacity for intersubjectivity, intuitively governing our social interactions and the interpersonal mirroring that undergirds the human capacity for empathy.
This social-synchronistic function of time is what New Yorker staff writer Alan Burdick examines in Why Time Flies: A Mostly Scientific Investigation (public library) — a layered, rigorously researched, lyrically narrated inquiry into the most befuddling dimension of existence.

Discus chronologicus, a German depiction of time from the early 1720s, from Cartographies of Time

Burdick begins at the beginning — the ur-question of how the universe originated from nothing and what this means for time, a question at the heart of the landmark 1922 debate between Einstein and Bergson that shaped our modern understanding of time. Burdick asks:

For argument's sake, I'll accept that perhaps the universe did not exist before the Big Bang — but it exploded in something, right? What was that? What was there before the beginning? Proposing such questions, the astrophysicist Stephen Hawking has said, is like standing at the South Pole and asking which way is south: "Earlier times simply would not be defined."

Nearly a century after Borges's exquisite refutation of time in language — "Time is a river which sweeps me along, but I am the river; it is a tiger which destroys me, but I am the tiger; it is a fire which consumes me, but I am the fire." — Burdick adds with an eye to the inherent limitations of our metaphors:

Perhaps Hawking is trying to be reassuring. What he seems to mean is that human language has a limit. We (or at least the rest of us) reach this boundary whenever we ponder the cosmic. We imagine by analogy and metaphor: that strange and vast thing is like this smaller, more familiar thing. The universe is a cathedral, a clockworks, an egg. But the parallels ultimately diverge; only an egg is an egg. Such analogies appeal precisely because they are tangible elements of the universe. As terms, they are self-contained — but they cannot contain the container that holds them. So it is with time. Whenever we talk about it, we do so in terms of something lesser. We find or lose time, like a set of keys; we save and spend it, like money. Time creeps, crawls, flies, flees, flows, and stands still; it is abundant or scarce; it weighs on us with palpable heft.
[…]
Yet whatever one calls it, we share a rough idea of what's meant: a lasting sense of one's self moving in a sea of selves, dependent yet alone; a sense, or perhaps a deep and common wish, that I somehow belongs to we, and that this we belongs to something even larger and less comprehensible; and the recurring thought, so easy to brush aside in the daily effort to cross the street safely and get through one's to-do list, much less to confront the world's true crises, that my time, our time, matters precisely because it ends.

Illustration by Harvey Weiss from Time Is When by Beth Youman Gleick, 1960

From the temporal meditations of the ancient philosophers to the last hundred years of ingenious psychological experiments, Burdick goes on to explore such aspects of his subject — a nearly infinite subject, to be sure, which makes his endeavor all the more impressive — as why time dilates and contracts depending on whether we are having fun or facing danger, how fetuses are able to coordinate their circadian activity, and what we are actually measuring when we speak of keeping time. In a fascinating chapter detailing the complex ecosystem of time-making — the inventions, standardizations, and global teams of scientists responsible for measuring and synchronizing earthly time — Burdick reflects on the tremendous coordination of human efforts keeping the world's clocks ticking:

Time is a social phenomenon. This property is not incidental to time; it is its essence. Time, equally in single cells as in their human conglomerates, is the engine of interaction. A single clock works only as long as it refers, sooner or later, obviously or not, to the other clocks around it. One can rage about it, and we do. But without a clock and the dais of time, we each rage in silence, alone.

Art by Lisbeth Zwerger for a special edition of Alice's Adventures in Wonderland

But our technologies are always prosthetic extensions of our consciousness — time, it turns out, is an innately social phenomenon not only in how it is measured, but in how it is experienced. Burdick cites the research of French neuropsychologist Sylvie Droit-Volet, who studies the warping of our temporal perception. In one experiment, she presented people with images of human faces — some neutral, some happy, some angry, some frightened — each displayed on the screen for anywhere between half a second to a second and a half. The research subjects were then asked to evaluate how long the faces appeared for.
She found that across images displayed for the same duration, happy faces were perceived to last longer than neutral ones and shorter than angry or fearful ones. Burdick explains:

The key ingredient seems to be a physiological response called arousal, which isn't what you might think. In experimental psychology, "arousal" refers to the degree to which the body is preparing itself to act in some manner. It's measured through heart rate and the skin's electrical conductivity; sometimes subjects are asked to rate their own arousal in comparison to images of faces or puppet figures. Arousal can be thought of as the physiological expression of one's emotions or, perhaps, as a precursor of physical action; in practice there may be little difference. By standard measures, anger is the most arousing emotion, for viewer and angry person alike, followed by fear, then happiness, then sadness. Arousal is thought to accelerate the pacemaker, causing more ticks than usual to accumulate in a given interval, thereby making emotionally laden images seem to last longer than others of equal duration… Physiologists and psychologists think of arousal as a primed physical state — not moving but poised to move. When we see movement, even implied movement in a static image, the thinking goes, we enact that movement internally. In a sense, arousal is a measure of your ability to put yourself in another person's shoes.

Art by Oliver Tallec from This Is a Poem That Heals Fish by Jean-Pierre Simeón

We perform this kind of emotional mimicry intuitively and incessantly over the course of our daily social interactions, in some degree donning the emotional and mental outfit of each person with whom we come into close contact. But we are also, apparently, absorbing each other's sense of time, which is encoded in our psychoemotional states. In another study, Droit-Volet found that research subjects perceived images of elderly faces to last shorter than they actually did and misjudged the duration of young faces in the opposite direction — viewers were essentially embodying the typically slower movements of the elderly. Burdick explains:

A slower clock ticks less often in a given interval of time; fewer ticks accumulate, so the interval is judged to be briefer than it actually is. Perceiving or remembering an elderly person induces the viewer to reenact, or simulate, their bodily states, namely their slow movement.

A book, Rebecca Solnit memorably wrote, is "a heart that only beats in the chest of another." In a very real sense, we are each a temporally open book and empathy a clock that only ticks in the consciousness of another. Burdick writes:

Our shared temporal distortions can be thought of as manifestations of empathy; after all, to embody another's time is to place oneself in his or her skin. We imitate each other's gestures and emotions — but we're more likely to do so, studies find, with people with whom we identify or whose company we would like to share.
[…]
Life dictates that we possess some sort of internal mechanism to keep time and monitor brief durations — yet the one we carry around can be thrown off course by the least emotional breeze. What's the point of owning such a fallible clock? … Maybe there's another way to think about it, Droit-Volet suggests. It's not that our clock doesn't run well; on the contrary, it's superb at adapting to the ever-changing social and emotional environment that we navigate every day. The time that I perceive in social settings isn't solely mine, nor is there just one cast to it, which is part of what gives our social interactions their shading. "There is thus no unique, homogeneous time but instead multiple experiences of time," Droit-Volet writes in one paper. "Our temporal distortions directly reflect the way our brain and body adapt to these multiple times." She quotes the philosopher Henri Bergson: "On doit mettre de côte le temps unique, seuls comptent les temps multiples, ceux de l'expérience." We must put aside the idea of a single time, all that counts are the multiple times that make up experience.
Our slightest social exchanges — our glances, our smiles and frowns — gain potency from our ability to synchronize them among ourselves, Droit-Volet notes. We bend time to make time with one another, and the many temporal distortions we experience are indicators of empathy; the better able I am to envisage myself in your body and your state of mind, and you in mine, the better we can each recognize a threat, an ally, a friend, or someone in need. But empathy is a fairly sophisticated trait, a mark of emotional adulthood; it takes learning and time. As children grow and develop empathy, they gain a better sense of how to navigate the social world. Put another way, it may be that a critical aspect of growing up is learning how to bend our time in step with others. We may be born alone, but childhood ends with a synchrony of clocks, as we lend ourselves fully to the contagion of time.

Perhaps Borges was right, after all, that time is the substance we are made of.
Complement the thoroughly fascinating Why Time Flies with James Gleick on how our time-travel fantasies illuminate consciousness, Patti Smith on time and transformation, T.S. Eliot's timeless ode to time, and Hannah Arendt on time, space, and our thinking ego, then revisit the story of how Rilke and Rodin gave birth to the modern meaning of empathy.
