In addition, they seem to respond to faces in somewhat the same way as humans. For example, humans tend to gaze at the right side of a person's face, which may be related to the use of right brain hemisphere for facial recognition. Research indicates that dogs also fixate the right side of a human face, but not that of other dogs or other animals.
Three new studies underscore the ways in which dogs meaningfully communicate with and understand humans, starting as puppies. Recent discoveries reveal how dogs are hardwired to understand and ...
Chimpanzees, dogs, gulls, horses, rats, roosters, sheep and sparrows all use similar short repeated sounds to tell others of the same species to come closer. [81] Even fish, which lack a neocortex, have been taught to distinguish and respond differently to different human faces (archerfish [82]) or styles of music (goldfish [83] and koi [84]).
Dogs may be able to differentiate between happy and angry expressions in people. They may also be able tell that these expressions correlate with positive and negative meanings, respectively--a ...
The more familiar a particular type of face (e.g. human or dog) is, the more susceptible one is to the face inversion effect for that face. This applies to both humans and other species. For example, older chimpanzees familiar with human faces experienced the face inversion effect when viewing human faces, but the same result did not occur for ...
The faces of dogs have evolved over tens of thousands of years to make them more appealing to humans, unlike the wild wolves they descended from, a new study Your furry friend's 'puppy dog eyes ...
The hamadryas baboon is one of many primate species that has been administered the mirror test.. The mirror test—sometimes called the mark test, mirror self-recognition (MSR) test, red spot technique, or rouge test—is a behavioral technique developed in 1970 by American psychologist Gordon Gallup Jr. to determine whether an animal possesses the ability of visual self-recognition.

Dogs presented with images of either human or dog faces with different emotional states (happy/playful or angry/aggressive) paired with a single vocalization (voices or barks) from the same individual with either a positive or negative emotional state or brown noise. Dogs look longer at the face whose expression is congruent to the emotional ...
