A Cornell University study from November 19, 2024, titled “Researchers assess whether animals feel emotion” (https://as.cornell.edu/news/researchers-assess-whether-animals-feel-emotion), explains that while it is absolutely true that animals feel emotions, there were limits they found within their study:
“One challenge for the 100 animal researchers surveyed is which biological markers to measure and how to adequately describe and quantify something as complex and variable as emotions. They may include everything from instinctual reactions of disgust or fear to deep feelings of affection and empathy for others. Animal studies are further complicated by the fact that researchers can’t ask an animal how it’s feeling. And while experiments with animals in labs can be tightly controlled, the results may be skewed since the animal is not interacting within its natural environment. Animal behavior experiments in the wild provide valid social and ecological contexts but they are challenging to design and to control.”
This vice article from 2017 (https://www.vice.com/en/article/would-someone-born-and-raised-in-solitary-have-any-emotions/), titled “Your Emotions Are a Social Construct” consults Lisa Feldman Barrett, the director of Northeastern University’s Interdisciplinary Affective Science Laboratory:
“‘Emotion requires something more than affect,’ Barrett says. ‘It requires making meaning out of that affect. That’s not something, if a child was born and grew up in the wild, with no other humans around, that would develop.' They would instead feel more vague sensations like pleasantness or unpleasantness; arousal or calmness—similar to the way that infants feel at a young age, or even the type of ‘emotion’ we see in animals (that we often ascribe deeper meaning to).”
Many human emotions are likely created by social constructs. Anthropomorphism skews our perspective, and makes us see animal emotions through the lens of our feelings. Animals definitely feel emotions and are able to create deep bonds with each other within and across species (“Individuals with a service dog exhibited significantly better psychosocial health including higher social, emotional, and work/school functioning” https://pmc.ncbi.nlm.nih.gov/articles/PMC6625941/) but it is impossible for us to know if they are the same as ‘human’ emotions.
In short, animals do not experience emotions in the same way we perceive them. It is currently impossible to know for sure the extent of their understanding of words, feelings, whatever, but there is clear evidence they feel basic emotions: clearly stuff like hunger and anger and discomfort (some dogs have sensory issues), fear, excitement, relief, and play. Further study is necessary to discover the extent of some of their capabilities for these emotions, and there are outliers, but it is safe to say that animals cannot feel human emotions in the sense humans can, as the claim suggests.
