In people, the mirror self-recognition ability generally arises between the ages of 18 months and 2 years and represents the beginning of a developmental process of achieving increasingly abstract psychological levels of self-awareness, including introspection, the researchers said.
Bottlenose dolphins (tursiops truncatus) show the capacity for mirror self-recognition (msr), an indicator of self-awareness, at an earlier age than humans and chimpanzees, as reported in a new study in plos one. The idea that mirror self recognition is a black & white distinction (you either have it or you don’t) was first challenged in another monkey study that we conducted, in which we showed that . Very few species have passed the mirror self-recognition test (msr) test as of 2016, only great apes (including humans), a single asiatic elephant, dolphins, orcas, and the eurasian magpie have passed the msr test. Previous research had shown that rhesus monkeys consistently failed in the mirror self-recognition test, an important test of self-awareness, but like apes and dolphins, they did seem to possess the ability to monitor their own mental states.
Abstract: mirror-self recognition (msr) is a behavioral indicator of self-awareness in young children and only a few other species, including the great apes, dolphins . Though humans can recognize themselves in a mirror starting at about a year old, dolphins start the process of self-recognition as early as 7 months old. To date, only humans and great apes have shown convincing evidence of mirror self-recognition two dolphins were exposed to reflective surfaces, and both dem- onstrated responses consistent with the use of the mirror to investigate marked parts of the body. Humans, chimpanzees, elephants, magpies and bottle-nosed dolphins can recognize themselves in a mirror, according to scientific reports, although as any human past age 50 knows, that first glance .
Analysis of mirror self-recognition in bottlenose dolphins: implications for comparative investigations of highly dissimilar species studies using chimpanzees, orangutans, and humans have shown displays of self-recognition with the introduction of a mirror the display, exhibited by these animals . For example, mirror self-recognition may be indicative of self-consciousness and, by extension, theory of mind (the ability to think about what others may be thinking) being self-conscious, or having knowledge of the self, may naturally lead to having knowledge of others. The ability to recognize oneself in a mirror is an exceedingly rare capacity in the animal kingdom to date, only humans and great apes have shown convincing evidence of mirror self-recognition two dolphins were exposed to reflective surfaces, and both demonstrated responses consistent with the use . In this posts i will deal with mirror self-recognition i’ll discuss the other two in my next post these capacities are most often mentioned in discussions of the mentality of primates, especially great apes, but there are also relevant results from other ‘clever’ species outside the primate lineage such as, for example, dolphins (eg .
Mirror self recognition in dolphins
To date, the only species to show compelling evidence of self-recognition are humans, chimpanzees, and orangutans / an important question is whether self-awareness is a uniquely primate (great ape . The researchers began investigating the possibility of self-recognition in dolphins by erecting a two way mirror behind a clear wall of the dolphins’ pool they observed that the dolphins appeared to show off in front of the mirror by swimming back and forth rapidly, twisting and turning, and opening and closing their mouths. The mirror test was developed by psychologist gordon gallup jr 1 in 1970 as a method for determining whether a non-human animal has the ability of self-recognition it’s also known as the “mark test” or “mirror self-recognition test” (msr) when conducting the mirror test, scientists . 5 bottlenose dolphins aquatic mammals have also been awarded with mirror self-recognition although the set-up had to be tailored a little differently.

- This piece on dolphins and the self-recognition test is an overview of well-known studies that have changed our thinking of dolphins and nonhumans alike the scientific community used to assume that having a sense of self is an attribute only found in humans and other great apes, but studies .
- In 2001, diana and i co-authored the first peer-reviewed paper to demonstrate mirror self-recognition in dolphins and today, i’m gratified to see our seminal finding replicated and published in a peer-reviewed journal.
Self-recognition, it has been argued, is a hallmark of advanced cognitive abilities in animals it was previously thought that only the usual suspects of higher cognition -- some great apes . The dolphin passes the miller test which recognizes himself in the mirror earlier than a human baby mirror self-recognition in the bottlenose dolphin: a case of cognitive convergence. Like the chimpanzees, the dolphins learned to use the mirror in a variety of ways, even “having sex in front of the mirror with each other, which we call our dolphin porno tapes,” marino says the three researchers published the results, saying they were “suggestive” of mirror self-recognition.
