Temple Grandin urges sensory-based desensitization to reduce horse spooking
Summary
At a Missoula conference, Dr. Temple Grandin said horses perceive the world through senses, not words, and urged slow, specific desensitization methods — using examples such as rotated objects, flags, tarps and trailer loading — to reduce fear and improve rider safety.
Dr. Temple Grandin, an animal scientist, told an audience in Missoula that horses live in a sensory-based world and that handlers should prioritize slow, specific desensitization to reduce spooking and improve safety. "You gotta get away from language, any animal. An animal lives in a sensory based world, not a word based world," she said during a keynote talk.
Grandin said that animals do not automatically transfer learning from one side to another and that novel objects can be both attractive and frightening. She described demonstrations in which a small plastic ‘‘bony pony’’ remained novel no matter how it was positioned, while simple plastic chairs sold at common stores were not novel enough to provoke consistent reactions. "Something new is both scary and attractive," she said, and recommended letting animals voluntarily approach new items rather than forcing encounters.
Most immediately, Grandin advised handlers to slow down and give horses time to look, adding that first experiences must be positive. She recommended exercises such as decorating fences with flags rather than thrusting a waving flag into a horse's face, introducing wheelchairs and other unusual items incrementally, and placing trailers and new equipment where animals can be fed so the first association is positive. Grandin recounted that when a news photographer flew a drone close to horses, it took "exactly 20 minutes for them to become rideable," underscoring how long severe fear reactions can last.
She cited experimental work showing that specific memories do not always generalize: training a horse to accept an umbrella did not necessarily make it tolerate a tarp, and objects rotated so they look different to an animal can become effectively new again. Grandin pointed to a student experiment in which an object placed in an alcove appeared different when rotated, and to published papers (searchable by keywords she suggested) documenting the phenomena.
Grandin also linked handling technique to rider welfare, saying a calm horse gives riders confidence while a frightened horse raises risks for both. She recommended practical changes: remove moving chains in facilities, use non-slip flooring in veterinary and handling areas, and introduce novel stimuli with a familiar person present when possible. She warned that severe fear memories can be persistent — citing a horse terrified of black cowboy hats after a painful experience — and that some animals may never be fully safe for certain activities but can often be improved.
Grandin closed by encouraging trainers to use simple, repeatable steps, checklists for sequences, and careful habituation rather than force. She offered further reading and said books and papers discussed in the talk would be available after the session.
