Dogs' learning success is enhanced when they are not only rewarded with food, but also praised and petted for their good performance, according to a new study by researchers from the Department of Ethology at ELTE Eötvös Loránd University, published in Scientific Reports. The ethologists investigated the relations among emotions, learning and sleep. Their results shed light on how learning style and sleep affect dogs' behavior and learning success.

Previous research has already shown that we remember events and information better when they are emotionally charged. However, these studies were mainly conducted in a controlled laboratory setting, so it is particularly important to study this question in real-life situations.

"It is natural and ordinary for family dogs to learn in emotionally charged , either from their owners or from dog trainers. However, our knowledge of this phenomenon so far is mainly based on studies in humans and laboratory rodents (rats, mice). Our aim was to study the phenomenon in dogs, as it is not only exciting to research the species as a model animal, but also in its own right," explains Dr. Vivien Reicher, first author of the study.

The researchers developed a unique methodology: in the presence of the owner, dog trainers taught new command words for tricks the dogs already knew. For example, they used the command word in English "High five" instead of the familiar Hungarian version "Pacsi."

Each dog was given two , one in "permissive" , where the trainers used lots of praise and petting in addition to a treat, and never scolded the dogs, and another "controlling" style, where the dogs were reinforced only with a treat, without verbal praise or petting, and they were scolded upon unwanted behavior.

After the training sessions, the dogs slept in the department's lab, and the researchers tested the dogs' success in learning the new command words before and after sleep. The dogs' sleep was analyzed using EEG scans to study the brain function related to memory consolidation, i.e. the stabilization of remembering new information.

The results showed that "controlling" training induced greater stress in the dogs. They sought the proximity of their owners more and slept more after training, confirming previous research that sleep plays an important role in emotion processing. Interestingly, their learning was more successful the first time (compared to the second occasion) regardless of training style, and permissive or controlling styles had no effect per se. The reason for the order effect may be the well-known phenomenon in the literature that information learned first is often easier to remember than what is learned later in a similar context.

Dr. Márta Gácsi, Senior Research Fellow of the Comparative Ethology Research Group of HUN-REN-ELTE, points out, "The most exciting result is that sleep improved the dogs' learning performance only in one specific case, when the group that received 'controlling' training for the first time expected to receive similar training for the second time, but then we trained them in a 'permissive' style. We believe the combined effect of positive surprise and sleep improved their learning success."

The results of the research highlight the important role that social reinforcement (praise, petting) plays in dogs' well-being and learning success. The lack of social reinforcement or scolding can cause stress for dogs, especially if they are being taught by a trainer, and this should be taken into account when choosing teaching methods.

This study not only provides a deeper insight into dog learning, but can also bring us closer to understanding some of the learning processes in humans. It also provides useful information for owners and dog trainers, as it further supports the view that rewarding our pets not only with food, but also with praise and petting, has a positive impact on their well-being and learning success.
