Head-orienting response and visual laterality at total population level in response to the broadcast of V+ (“positive” voices) and V− (“negative” voices). (a) Total number of right and left head-turning (One-sample Wilcoxon signed rank test); (b) Number of scans in which the horses, when released, had the loudspeaker in the right (RVH) and left (LVH) visual hemifield, according to the stimulus valence (means and S.E.M. are shown; Wilcoxon signed rank test). *P < 0.05.
