distinct facial expression
Researchers find horses have distinct facial expressions when they feel disappointed or frustrated
Horses have distinct facial expressions for disappointment and frustration, according to a study. Researchers at the University of Lincoln put 30 horses through a food-reward task, which made them either disappointed or frustrated. When disappointed, the horses tended to blink a lot, lift their nostrils, stick their tongue out and make chewing movements. When frustrated, they showed more of the whites of their eyes and rotated their ears backwards. Dr Claire Ricci-Bonot, lead author of the study, said that horses are'are generally gregarious animals, living within a complex social system'.
