Chimpanzees Have Long Term Memory

July 18, 2013

We humans can remember events in our lives that happened years ago, with those memories often surfacing unexpectedly in response to sensory triggers: perhaps a unique flavor or scent. Now, researchers reporting in Current Biology, a Cell Press publication, on July 18 have evidence to suggest that chimpanzees and orangutans have similar capacities. In laboratory tests, both primate species were clearly able to recollect a tool-finding event that they had experienced just four times three years earlier and a singular event from two weeks before, the researchers show.
