I cavalli, come è già stato appurato per i cani, sono in grado di riconoscere le emozioni degli umani, leggendo le espressioni facciali e quindi distinguendo, ad esempio, collera e felicità. A questa conclusione sono giunti ricercatori dell'Università del Sussex, che hanno studiato le reazioni di 28 equidi sottoposti all'osservazione di fotografie di persone.
Stando a quanto descritto su Biology Letters, gli animali tendevano a scrutare volti arrabbiati soprattutto con l'occhio sinistro, comportamento associato alla percezione di stimoli negativi, e -altro sintomo- la loro frequenza cardiaca aumentava di pari passo.
