In Chapter 2 of Biopsychology (9th Edition), you learned that chimpanzees have been shown to exhibit a set of behaviours that was hypothesized by some researchers as indicative of self-awareness or self-recognition. You also learned about how a test was developed, the mirror self-recognition (MSR) test, to address that hypothesis. Below is a video that begins with a demonstration of what happens when a chimpanzee is exposed to a mirror for the first few times; then, the video shows what typically happens during an MSR test in chimpanzees and in humans.
Although the text limited its discussion to self-recognition in chimpanzees, it is important to realize that research on self-recognition in nonhuman species has not been limited to chimpanzees. Other species have also been subjected to the MSR test. Below is a list of some of the species that have passed the MSR test.
6. Bottlenose dolphins
7. Killer whales
8. Asian elephants
9. European Magpies
The following video depicts a European Magpie passing the MSR test.
