Previous research has already documented the important functions of touch. Primates such as great apes spend hours a day grooming each other, even when there are no lice in their physical environment. They use grooming to resolve conflicts, to reward each other’s generosity, and to form alliances. Human skin has special receptors that transform patterns of tactile stimulation—a mother’s caress or a friend’s pat on the back—into indelible sensations as lasting as childhood smells. Certain touches can trigger the release of oxytocin, bringing feelings of warmth and pleasure. The handling of neglected rat pups can reverse the effects of their previous social isolation, going as far as enhancing their immune systems.
My work set out to document, for the first time, whether compassion can be communicated via touch. Such a finding would have several important implications. It would show that we can communicate this positive emotion with nonverbal displays, whereas previous research has mostly documented the nonverbal expression of negative emotions such as anger and fear. This finding would also shed light on the social functions of compassion—how people might rely on touch to soothe, reward, and bond in daily life.
In my experiment, I put two strangers in a room where they were separated by a barrier. They could not see one another, but they could reach each other through a hole. One person touched the other on the forearm several times, each time trying to convey one of 12 emotions, including love, gratitude, and compassion. After each touch, the person touched had to describe the emotion they thought the toucher was communicating.
Imagine yourself in this experiment. How do you suppose you might do? Remarkably, people in these experiments reliably identified compassion, as well as love and the other 10 emotions, from the touches to their forearm. This strongly suggests that compassion is an evolved part of human nature—something we’re universally capable of expressing and understanding.
MOTIVATING ALTRUISM
Feeling compassion is one thing; acting on it is another. We still must confront a vital question: Does compassion promote altruistic behavior? In an important line of research, Daniel Batson has made the persuasive case that it does. According to Batson, when we encounter people in need or distress, we often imagine what their experience is like. This is a great developmental milestone—to take the perspective of another. It is not only one of the most human of capacities; it is one of the most important aspects of our ability to make moral judgments and fulfill the social contract. When we take the other’s perspective, we experience an empathic state of concern and are motivated to address that person’s needs and enhance that person’s welfare, sometimes even at our own expense.
In a compelling series of studies, Batson exposed participants to another’s suffering. He then had some participants imagine that person’s pain, but he allowed those participants to act in a self-serving fashion—for example, by leaving the experiment.
Within this series, one study had participants watch another person receive shocks when he failed a memory task. Then they were asked to take shocks on behalf of the participant, who, they were told, had experienced a shock trauma as a child. Those participants who had reported that they felt compassion for the other individual volunteered to take several shocks for that person, even when they were free to leave the experiment.
In another experiment, Batson and colleagues examined whether people feeling compassion would help someone in distress, even when their acts were completely anonymous. In this study, female participants exchanged written notes with another person, who quickly expressed feeling lonely and an interest in spending time with the participant. Those participants feeling compassion volunteered to spend significant time with the other person, even when no one else would know about their act of kindness.
Taken together, our strands of evidence suggest that compassion is deeply rooted in human nature and has a biological basis in the brain and body. Humans can communicate compassion through facial gesture and touch, and these displays of compassion can serve vital social functions, strongly suggesting an evolutionary basis of compassion. And when experienced, compassion overwhelms selfish concerns and motivates altruistic behavior.
CULTIVATING COMPASSION
So we can clearly see the great human propensity for compassion and the effects compassion can have on behavior. But can we actually cultivate compassion, or is it all determined by our genes?
