Researchers from the CUNY Graduate Center and Hunter College have discovered that Asian elephants can control their impulses and change their behavior when situations change. This study, led by psychology professor Joshua Plotnik and postdoctoral researcher Sydney Hope, is the first to show that Asian elephants possess a specific cognitive ability known as inhibitory control. The findings, published in the journal PLOS ONE, may help improve conservation efforts by better understanding how elephants interact with human communities in shared landscapes across Asia.
In the study, 16 Asian elephants at the National Elephant Institute in Thailand were given a task involving a transparent box filled with fruit. The animals could see and smell the food through small holes in the box but were trained to reach through a side opening instead of directly toward the reward. When the box was rotated, changing the location of the opening, the elephants initially reached toward the old location. However, they quickly adjusted their behavior and learned to use the new opening, showing they could suppress their initial impulse and adapt to new conditions.
The researchers observed that older elephants took longer to adapt to the change in the box's orientation. While this might suggest age-related differences in cognitive flexibility, the team emphasizes that more research is needed to determine if this is due to a decline in cognitive abilities or simply a slower adaptation process. Regardless, the study highlights that elephants are capable of complex decision-making, which is essential when navigating unpredictable environments.
Joshua Plotnik has spent nearly two decades studying elephant intelligence, social behavior, and personality in Thailand, combining experimental research with conservation efforts. His work explores not only the cognitive abilities of elephants but also how these abilities influence their interactions with humans. Previous research by Plotnik and his team has shown that elephants can recognize themselves in mirrors, comfort distressed companions, coordinate with others, and solve new problems. These findings contribute to a growing understanding of the sophisticated mental capacities of elephants and may help predict how they behave in human-inhabited areas, ultimately aiding in the development of more effective conservation strategies.
