Detrimental reinforcement is a generally used method in horse coaching. Identified extra informally as ‘stress and launch’ coaching, these utilizing it apply it with various levels of subtlety and finesse: some trainers use it in ways in which seem to trigger horses seen misery, whereas others accomplish that in ways in which seem to not trigger horses misery in any respect.

Regardless of the latter use of damaging reinforcement throughout horse coaching, some individuals really feel that damaging reinforcement is all the time disagreeable for horses and thus its use ought to be averted as a lot as potential. Why do they consider this? Whereas it could possibly be their very own private biases, it might additionally end result from what they’ve realized from a textbook.

Some textbooks train that damaging reinforcement is a course of whereby an animal learns to keep away from an aversive occasion by responding to a warning stimulus that happens earlier than the aversive occasion. After the warning stimulus has been paired with the aversive occasion sufficient occasions the warning stimulus itself turns into a conditioned aversive – one thing that the animal learns is disagreeable. By this logic, even a lightweight rein cue (the warning stimulus) would turn into a conditioned aversive if paired with stress on the rein (the aversive occasion) to show a horse the way to flip – irrespective of if that stress was mild or very laborious. Nonetheless in accordance with analysis mentioned in Dr Paul Neuman’s speak, ‘What the textbooks don’t inform you about damaging reinforcement’, on the latest Artwork and Science of Animal Coaching (2020), this is not the case in any respect.

Dr Neuman defined that analysis not being mentioned in such textbooks presents a really completely different image: the warning stimulus doesn’t turn into a conditioned aversive stimulus; it turns into a discriminative stimulus – one thing that merely tells the animal that their behaviour which probably follows will likely be strengthened. Within the case of our horse instance above, the sunshine rein cue turns into a discriminative stimulus, telling the horse that their behaviour of turning will lead to no extra stress being added. To additional clarify this, whereas discussing analysis involving rats who acquired a warning (a tone or mild) earlier than receiving a shock, Dr Neuman identified that such advance warning stimuli made the rats wait longer to keep away from the shock. If these warning stimuli had been really conditioned aversive stimuli the alternative would have occurred: the rats would have responded as quickly because the lights/sounds started.

After we are coaching animals it’s essential to make sure that we’re minimizing inflicting the animal to really feel ache or disagreeable feelings comparable to concern throughout coaching. Detrimental reinforcement can certainly be utilized in methods that may frighten horses, or trigger them to really feel ache. Examples of this may be readily seen as you scroll via horse coaching movies posted by some skilled trainers on Fb. Nonetheless, damaging reinforcement also can certainly be utilized in ways in which do not end result within the horse feeling concern or ache. Simply as with the ‘different’ reinforcement process, optimistic reinforcement, damaging reinforcement generally is a useful software in our coaching toolbox, after we know the way to use it appropriately.

Dr Neuman’s speak has actually piqued my curiosity in diving a bit deeper into this analysis over the subsequent whereas.
