Grudges before gratitude

- Retaliation comes naturally to children, while positive reciprocity must be learned, says UCI cognitive scientist
When it comes to favors, we take for granted that there will be a payback. But the “you scratch my back, I’ll scratch yours” response is not instinctive; it must be learned. Even the psychologists who made this finding were surprised.
“In our series of experiments, we thought we’d see that children would display positive direct reciprocity – the tendency to pay back those who have helped – from an early age. That wasn’t the case,” says Nadia Chernyak, UCI assistant professor of cognitive sciences and lead author of the study, published in Psychological Science. “Preschool-aged children showed almost no awareness that they should repay favors.”
Kristin Leimgruber, visiting assistant professor of psychology at Franklin & Marshall College; Yarrow Dunham, assistant professor of psychology at Yale University; Jingshi Hu, former undergraduate researcher at Boston University; Peter Blake, associate professor of psychological & brain sciences at Boston University; and Chernyak were interested in how reciprocity develops. They conducted five experiments with 330 4- to 8-year-olds and discovered that the youngsters were more likely to reciprocate negative actions than positive ones.
The children played “giving” and “stealing” computer games, interacting with four avatars that they thought were other kids playing. In the giving version, everyone else got a sticker, leaving the subject without one until another player gave his or hers to the child. In the stealing version, the subject started with a sticker that was then stolen by one of the other players.
In the next phase of the giving game, the child received a second sticker that he or she could give to any one of the four avatars; while in the stealing game, the other players had stickers and the child had the opportunity to take a sticker from one of them. Would the kids give their second sticker to the player who had given one to them? Would they steal from the player who had stolen from them? The latter was mostly the case: Children were eager to retaliate but unconcerned with returning a favor until the age of 7 or older.
What can explain this puzzling behavior?
“Young children may not be naturally stingy; they simply don’t know the rule. Their principles look a little different than those of adults. It takes some cognitive building blocks, as well as exposure to social norms relevant to their culture, to learn how to navigate the world,” Chernyak says. “If the goal is to have children display gratitude, we should take opportunities to point out and discuss with them instances when other people are exhibiting this desired behavior.”
The last experiment was to find out if children would demonstrate positive direct reciprocity after an implication that they should.
One group of children was told a story about two kids who returned favors to each other. Another group heard a story about two youngsters who engaged in positive actions but not in any kind of reciprocal way. Both groups then played the giving game. Those who had heard the reciprocity story were now much more likely to pay back the person who gave them a sticker compared to the children who had heard the second story.
“And so the upshot isn’t so grim after all,” Chernyak says. “Grudges may come more naturally, but gratitude can readily be learned. Hearing a simple story was sufficient for young children to start following the norm of paying back favors.”
