Horses with over 30 Minutes of REM Sleep Show Better Persistence in Learning Tasks

Effect of horse sleep behavior on performance in a field-side spatial reversal learning test

Reduced rapid-eye-movement (REM) sleep is associated with impaired learning in many species. We developed a reversal learning test (RLT) suitable for field conditions to explore this association in 16 healthy horses. Nocturnal REM-like sleep behavior was recorded five times for 48 h over a six-week period. The horses performed a target training task followed by an RLT using two objects. When the horses reached a predefined frequency of touching …

Horses with over 30 minutes of REM sleep show better persistence in learning tasks

Just as for humans, sufficient sleep supports learning and coping for horses. A recent study at the University of Helsinki indicates that short periods of REM sleep impair horses' perseverance and performance in demanding learning tasks. In a study published in the journal Scientific Reports, an entirely new learning test suited to field conditions was developed to measure the learning capacity and motivation of horses in their own enclosures an…
