Many trainers of animals in the zoo now rely on positive reinforcement training to teach animals to voluntarily participate in husbandry and veterinary procedures in an effort to improve behavioral reliability, captive management, and welfare. However, captive elephant handlers in Nepal still rely heavily on punishment- and aversion-based methods. The aim of this project was to determine the effectiveness of secondary positive reinforcement (SPR) in training free-contact elephants in Nepal to voluntarily participate in a trunk wash for the purpose of tuberculosis testing. Five female elephants, 4 juveniles and 1 adult, were enrolled in the project. Data were collected in the form of minutes of training, number of offers made for each training task, and success rate for each task in performance tests. Four out of 5 elephants, all juveniles, successfully learned the trunk wash in 35 sessions or fewer, with each session lasting a mean duration of 12 min. The elephants' performance improved from a mean success rate of 39.0% to 89.3% during the course of the training. This study proves that it is feasible to efficiently train juvenile, free-contact, traditionally trained elephants in Nepal to voluntarily and reliably participate in a trunk wash using only SPR techniques.

When animals are trained to function in a human society (for example, pet dogs, police dogs, or sports horses), different trainers and training cultures vary widely in their ability to understand how the animal perceives the communication efforts of the trainer. This variation has considerable impact on the resulting performance and welfare of the animals. There are many trainers who frequently resort to physical punishment or other pain-inflicting methods when the attempts to communicate have failed or when the trainer is unaware of the full range of the potential forms of human-animal communication. Negative consequences of this include animal suffering, imperfect performance of the animals, and sometimes risks to humans, as repeated pain increases aggression in some animals. The field of animal training is also interesting from a semiotic point of view, as it effectively illustrates the differences between the distinct forms of interaction that are included in the concept of communication in the zoosemiotic discourse. The distinctions with the largest potential in improving human-animal communication in animal training, is understanding the difference between verbal communication of the kind that requires rather high cognitive capabilities of the animal, and communication based on conditioning, which is a form of animal learning that does not require high cognitive ability. The differences and potentials of various types of human-animal communication are discussed in the form of a case study of a novel project run by a NGO called Working Elephant Programme of Asia (WEPA), which introduces humane, science-based training and handling methods as an alternative to the widespread use of pain and fear that is the basis of most existing elephant training methods.
