From: Pet-directed speech improves horses’ attention toward humans
Horses’ behavior and heart rate variations during PDS and ADS. Boxplots showing median, first and third quartiles;. Grey dot: individual results (N = 28); Red Plus symbol: mean. Wilcoxon tests, NS not significant. (a) Attention index: (APDS-AADS)/(APDS + AADS) with APDS the time spent being attentive to the screen during PDS sections, and AADS during ADS sections. (b) Time spent in an alert posture when ADS or PDS was projected (s). (c) Time spent in a relaxed posture when ADS or PDS was projected (s). (d) Mean difference in heart rate between the last five and the first five seconds of the sections when ADS or PDS was projected (bpm).
