how do dogs see human faces

- December 6, 2020 -

This special feature could explain why dogs and humans have shared such a strong relationship through history. ', "The woman acted quite annoyed at me and told me, 'That doesn't make any sense. If so, this would be an innate ability that does not require education or experience to show itself. Dogs Watch Us Carefully and Read Our Faces Very Well. His brain certainly seems to have the apparatus to do so. I could be driving and my dog would be able to spot me through the window from afar. Why should this be happening? In this case, seven dogs were trained to endure the fMRI measurements required by the study. There is even some research which shows that similar cells can be found in the corresponding region of the brain of crows, and these are tuned to respond when the crow looks at bird-shaped faces. In turn, this area of the brain was relatively unresponsive to images of objects which were not faces. Actually, the situation is really simple—the brain of a dog is hardwired to recognize human faces. The content of this field is kept private and will not be shown publicly. I just don't believe that a young dog like this has the ability to understand anything about a human face. Our Faces in the Dog's Brain: Functional Imaging Reveals Temporal Cortex Activation during Perception of Human Faces. It adds to existing research showing that -- much like humans, other primates and even goats-- our canine friends use specific regions of their brain to "process" our faces. Now, new research suggests that dogs really do respond uniquely to tears. doi:10.1371/journal.pone.0149431. So, if a friendly Casper is trying to talk to us in a high-pitch voice, chances are it will be our dog picking up our end of the conversation, not us. One possibility is a process called co-evolution, which is where the evolution of one species affects the historical evolutionary changes of another. If you ever owned a dog, you'd know dogs don't respond to videos and pictures the way we do, because they know they're not living beings. If you put their living human behind a glass wall preventing any of their scent to come through, 100% the dog will recognize the human. The first evidence of the importance of this region came from patients who suffered damage to this part of the brain and developed prosopagnosia, which is a form of "face blindness". Do We Interpret Dog and Human Emotions in the Same Way? I could be driving and my dog would be able to spot me through the window from afar. Sheep can be trained to recognise human faces from photographic portraits -- and can even identify the picture of their handler without prior training -- according to new research. Once inside the scanner and settled into position the dogs were shown blocks of photographs of human faces (with neutral emotional expressions) or pictures of common objects (such as a coffee cup or a clock, etc.) So I said to her 'Dogs are really good at reading human faces so you might get a better response from your dog by smiling, or at least not using an obviously angry expression. Technically, cats can see in color, but they probably see us — and everything else — in a very different light than we do. One of the first examples of research exploring this question came from a team of investigators headed by Laura Cuaya of the Institute of Neurobiology at the National Autonomous University of Mexico. ANSWER: The overall results of their study indicate that dogs -- like humans and primates -- are indeed capable of facial recognition. She was getting frustrated with the dog and was scowling at it, and the dog was showing signs of stress and seemed to be trying to avoid looking at her face. 4 Reasons Why You Should Express Gratitude Every Day, Psychology Today © 2020 Sussex Publishers, LLC, A Memory Exercise to Rekindle Your Relationship’s Romance, CBT-E and FBT for Adolescents With an Eating Disorder, Noise Pollution Hampers Animal Communication. Some dogs will even paw at you and jump up at your chest or stomach looking for … Two separate lines of early research showed that face recognition is special. ', "I did remember that some researchers seemed to think that the ability that dogs have to understand faces was inborn rather than learned but I couldn't recall any details and didn't know exactly how to respond to her. The DFA was detected in the right hemisphere of the brain in all six dogs. Furthermore, I recalled that dogs don't seem to respond well to negative expressions [click here for more on that]. Increased neural activity tends to alter the nature of the magnetic field in defined regions of the brain and this can be measured. His face resembles a human! No other … Can you tell me what the facts really are?". Well, in an MRI study, they found that dogs show higher activation in this area as well when presented with faces, instead of objects. How would he know anything about human faces? The images were presented on a screen during single sessions lasting 190 seconds in sequences of 5 images displayed for 7 seconds. So it’s a little surprising that studies have shown that dogs are actually pretty good at recognizing human faces, even in photos. Published on 10/7/2019 at 3:37 PM . So a period of intensive training (which might involve months of working with the dogs) is required before you can actually collect data from them. We all know people treat their dogs like children, but do dogs think of humans as parents? His owner and a stranger walked in via separate doors, crossed in front of each other, then exited through different doors. She wrote, in part: "I was teaching a beginners dog obedience class and one woman, who was trying to train a young spaniel mix dog, seemed to be having difficulty. To be tested, the dog is required to remain motionless in a confined space in the MRI device for a period of time. It's not like I've been teaching him to understand expressions on my face—maybe by giving him a treat every time I smile and hitting him every time I have an angry face. Data shows that the same area of the canine brain which recognizes the faces and expressions of dogs is also tuned to recognize human faces Canines are much better at smelling than they are at seeing. Dogs Watch Us Carefully and Read Our Faces Very Well. Their view is uniquely feline, and understanding it may help you to understand your cat a little better. One possibility is a process called co-evolution, which is where the evolution of one species affects the historical evolutionary changes of another. Genetic Memories, Some Fears in Dogs May Be Innate, Dog's Brains Are Tuned to Recognize Human Faces. If so, this would be an innate ability that does not require education or experience to show itself. There are many reasons that trigger your dog to lick your face and that’s what we’re going to discuss in detail. Since dogs have been evolving into a species that shares the human environment, becoming more efficient at responding to the people in that environment would be an adaptive advantage and recognizing faces would be one aspect of this. During the viewing, brain activity was recorded for subsequent analysis. Dogs are so focused on our faces that they respond differently when they cannot see us. In recent studies, when dogs were presented with human faces, the ventral cortex part of the brain responded most powerfully. Actually getting dogs to participate in a fMRI-based study is not easy. Researchers describe how dogs in the study had difficultly recognizing their owners when two human subjects had their faces covered. Researchers in the University of Helsinki's Canine Mind research project found that oxytocin made dogs interested in smiling human faces. When presented with human faces the area of the brain which responded most vigorously in the dogs was the ventral temporal cortex (the front part of the temporal cortex), and this area was relatively unresponsive to images of objects which were not faces. while their brain activity was monitored. Humans possess a dedicated neural network for face processing, the researchers say. The results were relatively unambiguous. Threatening faces evoke unique responses in dogs. I recently received a note from a dog trainer that I first met at a meeting of the International Association of Canine Professionals (IACP). Another possibility is that during the process of domestication of dogs which spanned some thousands of years, humans might have systematically selected and nurtured dogs that responded accurately to human faces and emotional expressions. Hungarian researchers say dogs' brains may not process faces the same way human brains do. Of course, demonstrating this is not necessarily easy, but several pieces of research all lead to this conclusion. Dogs seem to pay particular attention to the eyes in a face. When your dog recognizes your face, you will see the telltale signs of them being happy and excited. "I remembered that there was some data which showed that dogs can recognize human faces and they react to the emotions that they see on them [click here to read more about that]. This is supported by the evidence found so far, that dogs, and no other canids, are able to recognize and attend to human faces without training.". So I said to her 'Dogs are really good at reading human faces so you might get a better response from your dog by smiling, or at least not using an obviously angry expression. ', "I did remember that some researchers seemed to think that the ability that dogs have to understand faces was inborn rather than learned but I couldn't recall any details and didn't know exactly how to respond to her. If you put their living human behind a glass wall preventing any of their scent to come through, 100% the dog will recognize the human. To figure this out, the team showed the dogs photos and videos of human faces, dog faces, and common objects, and monitored how their brains responded. So perhaps telling a novice dog trainer to keep smiling and avoid angry emotional expressions might be a reasonable bit of advice since it is likely that the dog is processing and interpreting their face. Cuaya LV, Hernández-Pérez R, Concha L (2016). Scientists began to ask themselves "If behavioral tests show that dogs are so good at recognizing human faces and expressions is it possible that they might have additional face-tuned cells in their brains—not just cells tuned to dog faces but cells tuned to respond to human faces as well?"
