Chimpanzees recognize themselves in mirrors
Article Abstract:
A study was conducted on chimpanzees' cognitive ability when subjected to their mirror images to test the anaesthetic recovery hypothesis developed by Heyes (1994). Two separate one-way analysis of variance were used to examine the significant differences in the level of their reactions. Results failed to uphold Heyes' hypothesis and are rather more supportive of the Gallup's self-recognition model.

Understanding visual barriers: Evidence for level 1 perspective taking in an orang-utan, Pongo pygmaeus
Article Abstract:
An adult female orang-utan used an untutored series of physical manipulations to guide humans to food placed beyond her reach. The results suggested that she was able to use her experience with visual barriers to model the visual perspective of visually impaired humans in a manner similar to that of 2- to 3-year-old human children.

Further reflections on self-recognition in primates
Article Abstract:
C.M. Heyes' is mistaken in his contention that self-recognition in primates is nothing more than an artefact of anesthetization and species differences in ambient face touching. Heye fails to support her position with the appropriate facts. Moreover, her arguments are based on a misappreciation of existing literature.
