Characterization of long-term memory, resistance to extinction, and influence of temperament during two instrumental tasks in horses

The present study investigated the influence of temperament on long-term recall and extinction of 2 instrumental tasks in 26 horses. In the first task (backward task), horses learned to walk backward, using commands given by an experimenter, in order to obtain a food reward. In the second task (active avoidance task), horses had to cross an obstacle after a bell rang in order to avoid emission of an air puff. Twenty-two months after acquisition, horses exhibited perfect recall performance in both tasks. Accordingly, no influence of temperament on recall performance could be observed for either task. In contrast, in the absence of positive or negative outcomes, the horses’ ability to extinguish their response to either task was highly variable. Resistance to extinction was related to some indicators of temperament: The most fearful horses tended to be the most resistant to extinction in the backward task, while the least sensitive horses tended to be the most resistant to extinction in the active avoidance task. These findings reveal extensive long-term memory abilities in horses and suggest an influence of temperament on learning processes other than acquisition.     

Horses are sensitive to baby talk: pet-directed speech facilitates communication with humans in a pointing task and during grooming

Animal Cognition - Pet-directed speech (PDS) is a type of speech humans spontaneously use with their companion animals. It is very similar to speech commonly used when talking to babies. A survey...

What drives horse success at following human-given cues? An investigation of handler familiarity and living conditions

Animal Cognition - Cues such as the human pointing gesture, gaze or proximity to an object are widely used in behavioural studies to evaluate animals’ abilities to follow human-given cues....     

Horses discriminate between human facial and vocal expressions of sadness and joy

Animal Cognition - Communication of emotions plays a key role in intraspecific social interactions and likely in interspecific interactions. Several studies have shown that animals perceive human...     

Unwilling or willing but unable: can horses interpret human actions as goal directed?

Animal Cognition - Social animals can gain important benefits by inferring the goals behind the behavior of others. However, this ability has only been investigated in a handful of species outside...     

Horses feel emotions when they watch positive and negative horse–human interactions in a video and transpose what they saw to real life

Animal Cognition - Animals can indirectly gather meaningful information about other individuals by eavesdropping on their third-party interactions. In particular, eavesdropping can be used to...
