Another result of the training: horses were eager to learn. "When horses realized that they were able to communicate with the trainers, i.e. to signal their wishes regarding blanketing, many became very eager in the training or testing situation," the researchers wrote in the study. "Some even tried to attract the attention of the trainers prior to the test situation, by vocalizing and running towards the trainers, and follow[ing] their movements. On a number of such occasions, the horses were taken out and allowed to make a choice before its regular turn, and signaled that they wanted the blanket to be removed. It turned out that the horses were sweaty underneath the blanket."
