The cows know to associate our face with our voice.
AGI - Cows are able to recognize human faces and associate a voice with the corresponding face. This curious result emerges from a study, published in the journal ‘Plos One’, conducted by scientists at the Institut national de recherche pour l'agriculture, l'alimentation et l'environnement. The team, led by Oceane Amichaud, collected information on 32 Prim'Holstein cows of the species ‘Bos taurus taurus’. The researchers showed the animals videos without audio of familiar and unfamiliar male faces, monitoring for how long they were stared at.
The experiment: video, audio and heart rate
The scientists sought to evaluate intermodal recognition, reproducing videos of known and unknown people while transmitting the audio corresponding to one of the two individuals. At the same time, the researchers measured the animals’ heart rate to understand if they reacted emotionally. The cows, according to the authors, showed a visual preference for new human faces compared to familiar ones and were able to associate the voice of a known trainer with the corresponding face.
The integration of multiple sensory modalities
When the videos were accompanied by sound, the animals spent more time staring at the video when the voice matched the face, demonstrating their ability to associate a face with the sound they heard. However, based on heart rate, neither of the faces or voices, familiar or unfamiliar, seemed to influence the emotional response of the cows. Although the authors note that a video and audio recording does not represent a complete interaction with a human, the results suggest that cows are able to distinguish between familiar and unfamiliar people and identify them from the face and voice.
New studies to protect the welfare of cattle
The authors specify that further investigations are needed to analyze how cows interact with specific people. This information, experts comment, can contribute to defining targeted strategies to protect the welfare of cattle. “Our work – the authors conclude – demonstrates that cows are able to process human faces presented in 2D in videos and associate familiar and unfamiliar faces with the corresponding voices, integrating multiple sensory modalities.”
