Summary
# Editorial Summary Horses' capacity to read human emotional states has significant implications for training, handling and therapy work, yet remains understudied compared to research on canine emotional sensitivity. Using a gaze-following paradigm, Baba and colleagues exposed 20 horses to human facial expressions (happy, neutral, and disgusted) paired with directional head turns, then measured whether horses followed the experimenter's gaze and how long they maintained visual attention. Horses demonstrated notably reduced gaze-following behaviour and shorter total looking time when exposed to disgusted expressions compared to neutral ones, with no significant difference between happy and neutral conditions—indicating selective sensitivity to negative human emotional cues rather than all emotional information. This finding suggests that domestication has enhanced horses' ability to interpret human affect as a meaningful environmental signal, potentially influencing their risk assessment and behavioural responses in handling situations. For practitioners, these results underscore the importance of emotional regulation during interactions with horses, as negative affect may signal danger or conflict and cause horses to disengage or alter their behaviour accordingly, making awareness of facial expression and body language messaging as critical as technical handling skills.

Practical Takeaways
- •Horses may perceive and respond to handler emotional states during training and handling; negative expressions could influence their behavior and willingness to engage
- •Understanding that horses detect human emotional cues supports the importance of handler awareness and emotional regulation during work with horses
- •Consider emotional expression as a potential variable affecting horse behavior during training, veterinary procedures, and routine handling situations
Key Findings
- •Horses significantly decreased gaze-following frequency and total looking time when presented with human disgust expressions compared to neutral expressions
- •Horses demonstrated sensitivity to human emotional cues (happy, neutral, disgust) through behavioral adjustment during gaze-following tasks
- •Results suggest horses interpret and respond to the meaning implied by negative human emotional cues, indicating possible domestication-related effects on inter-species emotional perception
