Animal training

Animal training is the process of teaching animals to provide specific responses to certain conditions or stimuli. This practice serves many different purposes in our world. Some animals are trained for companionship or as service animals to help people with disabilities. Others are trained for detection, protection, entertainment, or even scientific research.

Because the goals vary, the training methods must also vary. A seeing eye dog requires very different instruction than a wild animal performing in a circus. While some countries have certification bodies for trainers, these organizations often lack consistent requirements. In the United States, for example, there is no specific certification required to practice as an animal trainer.

To be successful, a trainer must consider the natural behaviors of the animal. They aim to modify these behaviors using a system of reward and punishment. There are four primary consequences used in the behavioral approach. Positive reinforcement occurs when a behavior is followed by a stimulus that increases how often that behavior happens in the future. Negative reinforcement involves removing an aversive stimulus after a behavior, which also increases the frequency of that behavior.

Conversely, positive punishment adds an aversive stimulus to decrease a behavior. Negative punishment involves removing a stimulus to cause a decrease in behavior. Behavior analysts often emphasize using positive reinforcement to grow desirable habits and negative punishment to reduce undesirable ones.

If a trainer uses punishment to stop a bad behavior, the animal must also be able to receive positive reinforcement for a better alternative. Trainers also use specific schedules of reinforcement to establish new behaviors. A fixed ratio schedule delivers a reinforcer after a specific number of responses. A variable ratio schedule delivers a reinforcer after a set number of responses that varies around an average.

There are also interval schedules based on time. A fixed interval schedule provides reinforcement after a set amount of time has passed. A variable interval schedule provides reinforcement after a variable amount of time has passed. While continuous reinforcement in a fixed ratio schedule helps during initial learning, a variable ratio schedule is most effective for maintaining behavior over long periods.

Trainers use several techniques to prompt specific responses. One method is shaping, which is the process of rewarding successive approximations of a behavior. This continues until the animal reaches the desired response topography, or physical form.

Trainers may also use conditioned reinforcers, such as clickers, to bridge the gap between a response and the actual reward. This helps the animal understand exactly which action earned the prize. Other tools include discriminative stimuli, such as signals, targets, or cues. These prompts can be changed or faded in magnitude to control how the animal responds. To prevent satiation, or the animal losing interest in a reward, trainers should keep the reinforcer size as small as possible while remaining effective.

Different species require different approaches based on their biology. Horses are prey animals, so trainers work hard to overcome their natural flight or fight instincts. Unlike dogs, horses are often more motivated by negative reinforcement, such as the release of pressure.

Once a horse learns a task, they have a remarkably long memory. Dogs, however, respond strongly to positive reinforcement like food or social rewards, such as petting.

Even birds can be trained for complex tasks. Some birds of prey are trained for falconry, while others are taught to be companion animals. Even chickens can be trained to navigate obstacle courses or discriminate between shapes using operant conditioning.

Training has a deep history and many interesting applications. In China, the practice of training cormorants to catch fish has lasted for over 1,200 years.

In the United States, some prison programs use service dog training to help inmates improve their socialization skills. The entertainment industry also relies on trained animals, leading to the creation of the Patsy Awards in 1939. These awards recognize animal stars in film and television. One trainer, Frank Inn, received over 40 of these awards.

Even insects are part of this field, with specialists like Steven R. Kutcher working with them.

Ultimately, animal training connects biology with human needs. It involves understanding complex concepts like stimulus control, motivating operations, and desensitization. It can also involve chaining, where several behaviors are linked together.

Whether training an elephant to recognize more than 20 words or a dog for agility, the goal is to create a functional relationship between the animal and its environment. This field spans from the highly structured world of Olympic horse dressage to the specialized care of marine mammals in zoos.
