Mirror-image responses in pygmy marmosets (Cebuella pygmaea)

The pygmy marmosets displayed a rapid extinction of social threat responses to their own image and of novelty responses to mirrors, but continued to show mirror-specific responses such as following their own image, playing peek-a-boo, and looking at their image...
