Take it or leave it: transport of tools for future use by long-tailed macaques (Macaca fascicularis).

Future planning has previously been considered unique to humans. However, certain animals can foresee some of their future needs. We tested long-tailed macaques (Macaca fascicularis) ability to transport and after a delay use a rake, in two experiments.

Chimpanzees (Pan troglodytes) fail a what-where-when task but find rewards by using a location-based association strategy.

Recollecting the what-where-when of an episode, or episodic-like memory, has been established in corvids and rodents. In humans, a linkage between remembering the past and imagining the future has been recognised. While chimpanzees can plan for the future, their episodic-like memory has hardly been investigated.
