New research suggests that chimps have an episodic memory for tasks they did three years ago.

Two major functions of a brain are to predict (and control) the future.
  • To the extent that events happening in the future echo events that happened in the past, it is just sensible for a brain to remember events that happened in the past. This allows some control over the outcome of an event by repeating the previous action, or perhaps to change the outcome by selecting an alternative action.
  • Surely, this capability makes sense for all species, provided they can support the increased metabolic load of a larger brain.
  • However, sometimes the environment changes, and earlier events are no longer a good guide to the future. So it makes sense that every time an event recurs, the outcome of that event is re-evaluated, and potentially a different outcome stored for future reference.
  • For humans, we know that recalling an event can also make the memory malleable.
  • Both humans and animals recall events during dreaming, which may be a way of reinforcing or weakening old memories.
  • It's just harder to ask an animal about its experiences...
