Can dogs read your facial expressions? It depends on your mood
Dogs are known to recognize and respond to human facial expressions, but a new study shows how deeply they understand our mood
Researchers have found that dogs can recognize and react to different human facial expressions, particularly happiness. In a study published in the journal iScience, eight dogs were trained to remain still in an fMRI machine while being shown images of human faces expressing happiness, sadness, anger, and fear. The caudate nucleus, a brain region associated with reward processing, was particularly active when the dogs viewed happy faces.
This suggests that dogs can differentiate between positive and negative emotions at a neurobiological level. However, the study did not find a significant difference in brain activity between fear and anger, or sadness and anger. It is unclear whether dogs' ability to process facial expressions is innate or learned through experience.
The researchers noted that the dogs were mostly looking at unfamiliar faces, which may impact their ability to recognize familiar emotions.
