It ’s heavy to know how overbold brute are for the simple reason that they ’re not capable to come justly out and tell us . scientist have developed various method acting over the age to assess animal intelligence , but a dim-witted new body - awareness test require elephants may be a promising new pecker to add to the armoury .
Anew studypublished in Scientific Reports shows that elephants know when their lumber bodies are an obstacle to achieving a destination . In an experiment led by Josh Plotnik from the University of Cambridge , elephant passed a trunk - cognizance test , point that they are capable of recognise themselves as being separate from their surround . This new test contributes to our discernment of elephant news , but it also shows that we ask to make intelligence test that are n’t biased towards human capacity .
determine an animal ’s content for ego - cognisance — that is , the capacity for self-contemplation , and the ability to recognize oneself as being separate from other individual or objects — is not soft . The Greco-Roman way to do this is the mirror ego - credit examination ( MSR ) , which requires animals to recognize the reflection in a mirror as being their own . Sounds relatively aboveboard , but that ’s because we ’re humans . This task is absurdly soft for appendage of our speciesolder than 18 months of long time .
Of all the animals that dwell on this major planet , only a precious few can pass the mirror tryout , include great imitator , dolphin , magpies , and elephants . Recognizing the capacity for ego - knowingness in an animal is authoritative because it ’s revelatory of other cognitive and social science , such as conjunct problem solving , position taking , and empathy .

Arecent experimentshowed that monkeys can pass the mirror mental testing too , but they had to be trained to understand how reflections work . For rascal , this is n’t a natural ability , and it ’s not totally vindicated from this experimentation that monkeys are truly grasping the concept . But that does n’t intend monkeys are n’t self - cognisant , or well-informed in other meaningful ways . A trouble with the mirror test is that it ’s biased towards certain animate being , particularly those that are more visually oriented . And there ’s more to intelligence and self - sentience than merely looking into a mirror .
That ’s where the new body - awareness run come in . This tryout is n’t meant to put back the MSR , but it is designed to provide researcher with an alternative means to screen for cognisance in animal . It ’s adopted from a test in whichchildren are asked to push a shopping cart , but the cart is attached to a matt on top of which the fry are standing . In man , the ability to make a connection between ego and the surroundings comes after the age of 18 months . Plotnik , along with his workfellow Rachel Dale , want to see how elephant would respond to a similar psychometric test .
“ Elephants are well regarded as one of the most intelligent animals on the satellite , but we still require more empirical , scientific evidence to support this belief , ” observe Dale in a release . “ We eff , for example , that they are open of thoughtful cooperation and empathy , and are able to recognize themselves in a mirror . These abilities are extremely unusual in animals and very rare indeed in non - archpriest . We need to see if they also show ‘ trunk - awareness ’ . ”
For the run , the investigator attached a stick to a safe mat with a Mexican valium . Elephants were required to walk on top of the mat , pick up the stick and pass it to a person standing in front of them . But as the elephant cursorily discovers , the reefer ca n’t be lifted all the way because it ’s standing on top of the mat . for be able to pass on the stick over , the elephant must step off the lustrelessness and try again .
Perhaps unsurprisingly , elephants excelled at this task . In tests involving 12 elephants , the animals successfully dispatch the task well-nigh 90 per centum of the clock time . This propose that elephants are open of recognizing themselves as being freestanding from physical object or their environment , and they appear to have a level of ego - understanding — intertwined with their ability to pass the mirror test — that ’s quite rarified among animate being . The sample size is small but the authors witness their results statistically significant nevertheless . That said , this study appear to be the first to use a torso - awareness test on animals , so further research will be need to corroborate these findings .
Regardless , these finding show how authoritative it is for scientists to grow intelligence run that are specific to the species in question . As the authors reason in their study :
distinctly , there is a need for heavy variableness in the ways in which psychologists measure non - human animals ’ understanding of self . Specifically , greater attention is needed to the development of more refreshing , relative and ecologically valid coming that take the evolutionary strengths — size and sensory in exceptional — of individual species into accounting .
In other words , we have to contain make test that are biased towards human capacities , and create new tests that allow animals to let us get it on just how smart they really are . We reached out to the study ’s authors for comment and we ’ll update this position should we hear back .
