Negative reinforcement in horse training probed

A Danish written report has shown negative reinforcement to be beneficial inwards getting horses used to unfamiliar objects, precisely comes amongst a warning over stress responses inwards animals.

The results of the written report past times Janne Winther Christensen, of Aarhus University, convey been published inwards the Equine Veterinary Journal.

Christensen said the mightiness of horses to habituate to new objects influences security inwards the horse-human relationship. However, the effectiveness of dissimilar ways of habituating Equus caballus had non been investigated inwards detail.

Christensen gear upward close investigating whether horses showed increased stress responses when negatively reinforced to approach new objects, compared to horses that were allowed to voluntarily explore the objects.

The interrogation besides gear upward out to notice whether negative reinforcement aided object habituation.

Twenty-two 2 to iii yr one-time Danish Warmblood geldings were used inwards the study.

Half were negatively reinforced past times a familiar human handler to approach a collection of new objects inwards a exam arena. The other one-half of the horses – the voluntary grouping – were individually released inwards the arena too were complimentary to explore the objects.

On the adjacent day, the horses were exposed to the objects i time again without a human to let the charge per unit of measurement of habituation to survive investigated.

Behavioural too heart-rate responses were recorded during the study.

Christensen constitute that all horses inwards the voluntary grouping initially avoided the unknown objects, whereas the handler was able to cash inwards one's chips all negatively reinforced horses to approach too stand upward adjacent to the objects inside the start two-minute session.

The negatively reinforced horses had a significantly longer duration of alertness too a higher maximum middle charge per unit of measurement inwards the start session. On the next day, however, the negatively reinforced horses spent significantly less fourth dimension investigating the objects too approached a feed container, placed adjacent to the objects, faster than the voluntary group, indicating increased habituation.

Christensen constitute that piece the approach using negative reinforcement aided habituation inwards immature horses to approach  novel objects, at that topographic point was an  increased stress reply during  initial exposure.

“Although negatively reinforced approach appears beneficial for habituation, the physical care for should survive carefully managed due to increased stress responses inwards the Equus caballus which may constitute a security risk,” Christensen said.

“Further experiments should aim to investigate differences inwards stimulus intensity.”
