Abstract

People plan to act in the future when an appropriate event occurs, a capacity known as event-based prospective memory. Prospective memory involves forming a representation of a planned future action, subsequently inactivating the representation, and ultimately reactivating it at an appropriate point in the future. Recent studies suggest that monkeys, chimpanzees, and rats display elements of prospective memory, but it is uncertain if the full sequence (activation-inactivation-reactivation) that occurs in humans also occurs in nonhumans. Here, we asked if rats exhibit event-based prospective memory. Rats completed an ongoing temporal-discrimination task while waiting for a large meal. To promote the use of event-based prospective memory, we created an event (tone pulses) that provided information that the meal could be obtained soon. Event-based prospective memory was suggested by the dramatic decline in ongoing-task performance after the event, with excellent performance at other times. To document that the event initiated memory activation, we arranged for the event to occur at novel times. Finally, multiple, repeated presentations of the event on the same day demonstrate that rats inactivate and reactivate the memory representation in an on-demand, event-based fashion. Development of an animal model of prospective memory may be valuable to probe the biological underpinnings of memory disorders.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
