Reflection, isolation

Our gregarious great ape cousins — chimpanzees, bonobos, orangutans and gorillas — along with dolphins and Asian elephants, have passed the famed mirror self-recognition test, which means they will, when given a mirror, scrutinize marks that had been applied to their faces or bodies. The animals also will check up on personal hygiene, inspecting their mouths, nostrils and genitals.

Yet not all members of a certifiably self-reflective species will pass the mirror test. Tellingly,...“animals raised in isolation do not seem to show mirror self-recognition.”
-- from an article on mirrors and psychology.
