Who's bad? Chimps figure it out by observation

Chimpanzees make judgments about the actions and dispositions of strangers by observing others’ behavior and interactions in different situations. Specifically, chimpanzees show an ability to recognize certain behavioral traits and make assumptions about the presence or absence of these traits in strangers in similar situations thereafter. These findings, by Dr. Francys Subiaul - from the George Washington University in Washington DC - and his team, have just been published online in Animal Cognition, a Springer journal.
