They assigned each horse a "calm score," which ranged from 1 to 5 (1 being very calm and 5 being very excited) and was based on "the level of calmness observed as several people walked in and out of the stall." The researchers separated the horses into two groups; one group acted as a treatment group and the other as controls. After about one week, the researchers subjected the groups to the opposite treatment.
