A recent study published in Scientific Reports reveals that cats outshine human toddlers in their ability to form connections between images and words. In an experiment by Saho Takagi and her team at Azabu University in Japan, cats demonstrated this skill nearly four times faster than toddlers.
Although language comprehension is often considered uniquely human, various animals have shown the ability to associate sounds with symbols. Apes, African gray parrots, and even dogs have been trained to recognize and respond to specific words. However, cats have generally been less studied despite being one of humans’ closest animal companions. “Cats can definitely recognize the sound of words coming from people,” explained Dr. Carlo Siracusa, a veterinary behaviorist at the University of Pennsylvania, adding that cats are increasingly shown to rely on human interactions to solve problems.
In the study, 31 adult cats were shown two brief cartoon clips. The first clip paired a red sun with the nonsense word “paramo,” while the second paired a blue unicorn with “keraru.” Researchers repeated these clips until the cats lost interest, then swapped the pairings to see if the cats would notice. When the images were mismatched with their original sounds, the cats appeared confused and looked at the screen for 15% longer than usual, suggesting that they had indeed formed word-image associations. Some cats even showed heightened curiosity with dilated pupils when exposed to the mismatched clips, Takagi noted, adding that it was “cute to see how seriously they participated.”
Interestingly, cats formed these associations after just two nine-second exposures, whereas toddlers typically require multiple, longer exposures to achieve the same result. Yet Dr. Siracusa warns that such comparisons should be viewed cautiously. “You’re comparing an adult animal with an immature animal from a different species,” he said, pointing out the natural differences in how humans and animals are observed. While cats demonstrated an ability to link words and images, whether this stems from an inherent cognitive skill or is a byproduct of domestication remains uncertain.
