Data from: Behavioral evidence for memory replay of video episodes in the macaque

Humans recall the past by replaying fragments of events temporally. Here,
we demonstrate a similar effect in macaques. We trained six rhesus monkeys
with a temporal-order judgement (TOJ) task and collected 5000 TOJ trials.
In each trial, they watched a naturalistic video of about 10 s comprising
two across-context clips, and after a 2-s delay, performed TOJ between two
frames from the video. The monkeys apply a non-linear forward,
time-compressed replay mechanism during the temporal-order judgement. In
contrast with humans, such compression of replay is however not
sophisticated enough to allow them to skip over irrelevant information by
compressing the encoded video globally. We also reveal that the monkeys
detect event contextual boundaries and such detection facilitates recall
by an increased rate of information accumulation. Demonstration of a
time-compressed, forward replay like pattern in the macaque monkeys
provides insights into the evolution of episodic memory in our lineage
