Horse people talk to their horses. We praise them, cajole them, complain to them, tell them our cares and worries, and sometimes even shout at them. Many of us believe our tone of voice, if not the words, affect our horse’s behaviour. Heleski et al conducted a study in 2014 to find out to what extent soothing voice cues versus harsh ones assist in training.

Their hypothesis was that a soothing cue as the horse progressed through a potentially frightening task would improve the speed with which the horse was able to complete it calmly, while a harsh cue provided as the horse progressed would slow down the learning process and increase arousal.

Over 100 horses from different stables through Europe and the United States had five trials to cross a tarpaulin spread on the ground. The horses were randomly assigned to harsh voice treatment (quit it!) and soothing voice treatment (good horse). The handler led the horse towards the tarp using pressure and release on the halter, adding the vocal cue appropriate to the horse’s random assignment for each correct step towards the tarp. If the first crossing attempt took longer than ten minutes, the horse was considered to have failed. The goal was for horses to cross calmly within five trials. The time taken to cross each time, the horse’s heart rate, and its general behaviour were observed and recorded.

Interestingly, their findings were opposite to their hypotheses. There was no significant difference between harsh voice and soothing voice treatment groups in the percentage of horses that failed the learning task, in the groups’ average heart rates, or in the total time each group required to cross calmly. The maximum heart rate of the soothing voice group was actually higher than that of the harsh voice group.

There were no significant correlations with the horses’ ages when taken as an average. However, when 3-4 year old horses were compared with those 20 years or more, the older ones had much less latency to cross.

In the end, the harsh voice treatment group actually completed the learning task significantly faster than the soothing voice group. The researchers hypothesized that these unexpected results may show that tone of voice is either not distinguishable to the horse, or is not as salient to the horse as pressure cues, and may have ended up being perceived as ‘background noise’. They also suggested that handlers who were more familiar to the horses might have produced different results.

This suggests that while a soothing voice is likely not inherently calming to a horse in a novel situation, yelling at a horse for unwanted behaviour is equally ineffective. It is, however, theoretically possible with classical conditioning to teach a horse the difference between soothing voice and harsh voice. A soothing voice may additionally help the handler to remain calm, and correlations between horse and handler heart rates have been previously shown.

So, keep talking to your horse. Just realize that he is not taking in everything you are saying, and how you are saying it. Instead, make sure your training is clear so you get the responses you want.

  1. Amazing. I would never have guess this. Live and learn. Of course one of the ways of learning is reading.
