Total looking time of horses. Total looking time of the horses during two gaze-emotional cue presentations per trial of each experimental condition. The maximum total looking time was 180 frames because the experimenter presented each gaze-emotional cue for 90 frames (3 s). The median in each condition was 0 in the Happy condition, 19 in the Neutral condition, and 0 in the Disgust condition (* p < 0.05) (30 frames = 1 s).
