Asian elephants comfort each other in times of distress

Asian elephants console others who are in distress, using physical touches and vocalizations, finds a study to be published in the open access journal PeerJ. The findings are the first empirical evidence of consolation in elephants, says lead author Joshua Plotnik, who began the research as a graduate student of psychology at Emory University.

“For centuries, people have observed that elephants seem to be highly intelligent and empathic animals, but as scientists we need to actually test it,” he says.

Consolation behavior is rare in the animal kingdom, with empirical evidence previously provided only for the great apes, canines and certain corvids.

“With their strong social bonds, it’s not surprising that elephants show concern for others,” says co-author Frans de Waal, an Emory professor of psychology and director of Living Links at Emory’s Yerkes National Primate Research Center. “This study demonstrates that elephants get distressed when they see others in distress, reaching out to calm them down, not unlike the way chimpanzees or humans embrace someone who is upset.”

Plotnik received his Ph.D. from Emory in 2010 and is currently a lecturer in conservation biology at Mahidol University in Thailand and CEO of Think Elephants International, a non-profit focused on education and conservation. His main research interest is convergent cognitive evolution: The independent evolution of similar features of intelligence in species of different lineages.

While Plotnik was still at Emory, he and de Waal provided evidence that elephants can both recognize themselves in a mirror – a test of self-awareness passed only by some apes, dolphins and magpies – and problem-solve cooperatively.

“Humans are unique in many ways, but not in as many ways as we once thought,” Plotnik says.

The current study focused on a group of 26 captive Asian elephants spread over about 30 acres at an elephant camp in northern Thailand. For nearly a year, the researchers observed and recorded incidences when an elephant displayed a stress reaction, and the responses from other nearby elephants.

The initial stress responses came from either unobservable, or obvious, stimuli: Events such as a dog walking past, a snake or other potentially dangerous animal rustling the grass, or the presence of another, unfriendly elephant. “When an elephant gets spooked, its ears go out, its tail stands erect or curls out, and it may emit a low-frequency rumble, trumpet and roar to signal its distress,” Plotnik says.

The study found that nearby elephants affiliated significantly more with a distressed individual through directed, physical contact following a stress event than during control periods. As a typical example, a nearby elephant would go to the side of the distressed animal and use its trunk to gently touch its face, or put its trunk in the other animal’s mouth.

The gesture of putting their trunks in each other’s mouths is almost like an elephant handshake or hug, Plotnik says. “It’s a very vulnerable position to put yourself in, because you could get bitten. It may be sending a signal of, ‘I’m here to help you, not hurt you.'”

The responding elephants also showed a tendency to vocalize. “The vocalization I heard most often following a distress event was a high, chirping sound,” Plotnik says. “I’ve never heard that vocalization when elephants are alone. It may be a signal like, ‘Shshhh, it’s okay,’ the sort of sounds a human adult might make to reassure a baby.”

In addition, elephants frequently responded to the distress signals of other elephants by adopting a similar body or emotional state, a phenomenon known as “emotional contagion,” which may be related to empathy. Groups of nearby elephants also were more likely to bunch together, or make physical contact with each other.

As an example of emotional contagion in humans, Plotnik describes a couple watching a movie: “When a character on the screen is scared, the hearts of the couple watching might race and they might move a bit closer and hold each others hands.”

Decades ago, de Waal was one of the first to provide evidence of reconciliation in non-human primates, showing how chimpanzees make up with one another after a fight. De Waal’s research also demonstrated consolation behavior: After two chimpanzees fight, a third individual may come over and console the distressed loser of the battle with an embrace.

Reconciliation behaviors have since been demonstrated in many more species than those that have shown the capacity for consolation. “One hypothesis for why we don’t see consolation as often is that more complex cognition may underlie it,” Plotnik says. “Rather than just functioning as a way to maintain or repair relationships in a social group, consolation may also require empathy: The ability to put yourself emotionally into someone else’s shoes.”

The current elephant study’s limitations include the fact that it was restricted to captive animals. “This study is a first step,” Plotnik says. “I would like to see this consolation capacity demonstrated in wild populations as well.”

Wild populations of elephants, however, are becoming increasingly scarce: Both Asian elephants and African elephants are endangered.

In addition to conducting research, Plotnik strives to educate children in Thailand and the United States about the importance of conserving elephants and their shrinking habitats.

“I really believe that to save elephants and other endangered species, we must educate children about them,” he says. “Part of our Think Elephants International curriculum is getting kids directly involved in the research we do, so they learn first-hand about these amazing animals. Elephants are incredibly majestic and there is still so much to learn about their behavior and intelligence.”

  1. I share these same sentimentalities over elephants. It is clear that they experience many, if not all, human emotions and they interact with and support each other much in the same ways as we do. I watched a documentary about South African elephants a few years ago, where they filmed a herd of elephants grieving the death of a young calf. They would gather around the carcass, tenderly touching the bones with their trunks. Even though the calf had been dead for some time, they clearly still experienced emotional pain at recognising the bones. What psychological impact do you think poaching must have on them?

  2. Wow! Elephants truely are wonderful creatures arent they! As a proudly South African, i cant help but feel a tad overwhelmed with great pride but also deep pain.

    South Africa is one of the lucky places which have wild roaming elephants in our lands. We get to watch first hand how elephants console each oher through the difficulties of life and help one another as a family would. Elephants are truely magnificent when it comes to the structure of a herd. Not only does a mother teacher her babies what food to eat and what food not to, the elder male is in charge of disciplining the younger men to ensure that no rogue elephants occur. Elephants are not only emotionally smart, but are also extremely intelligent. African elephants remember their way, every year, from South Africa all the way up into Botswana to the Okovango Delta. Amazing right!

    This complex and beautiful animal has every right to live happily and freely but unfortunately, poachers are standing in the way. Due to the ever increase in demand for ivory, elephants are becoming more and more scarce in our country. It is deeply painful to know that one of our Big 5 animals might just be killed off before my children or my grandchildren get to witness one in real life.

    If only people would stop being so ignorant and cruel and understand the true beauty which is the elephant. Maybe they would second guess the ”healing affects” of ivory after all.
