According to a new study by researchers from the University of Vienna published in the journal <\/span>iScience<\/i>,<\/span> dogs’ brains not only distinguish between positive and negative emotions,<\/span> but are also able to differentiate between various negative human facial expressions,<\/span> such as fear and sadness.<\/span> Although previous experiments studied dogs’ perception of human facial expressions only at a general level,<\/span> the new paper confirms for the first time that four-legged pets are also capable of differentiating negative emotions within the same category.<\/span><\/p>\n

Within the framework of the study,<\/span> scientists examined the brain activity of dogs that were specially trained to stay calmly and without any restriction inside a magnetic resonance imaging (MRI) scanner.<\/span> In the first experiment,<\/span> the animals were shown photos of happy and neutral faces of unfamiliar people.<\/span> The results showed that when happy facial expressions were shown,<\/span> activity increased significantly in the areas of the dogs’ brains that control visual,<\/span> social,<\/span> and reward-related processes.<\/span><\/p>\n

In the second experiment,<\/span> scientists showed 12 dogs four different human facial expressions:<\/span> joy,<\/span> sadness,<\/span> fear,<\/span> and anger.<\/span> Through machine learning and analysis of complete brain activity,<\/span> it was determined that a dog’s brain easily distinguishes a happy face from a negative one,<\/span> and scanning of brain regions showed that the animals distinguish between fear and sadness,<\/span> as well as fear and anger faces (except for cases of anger and sadness,<\/span> which they found difficult to tell apart).<\/span><\/p>\n

According to the researchers,<\/span> perceiving different negative emotions is important for dogs because they are associated with different types of threats,<\/span> although to distinguish between anger and sadness,<\/span> they may require additional cues,<\/span> such as human body language.<\/span> The obtained results once again highlight how the dog’s brain has changed during thousands of years of coexistence and domestication with humans,<\/span> which in practice\u2014for example,<\/span> when training dogs\u2014provides the opportunity to effectively use positive emotions.<\/span><\/p>\n
