abstract = {People retain more new verbal episodic information for at
least 7 days if they rest for a few minutes after learning
than if they attend to new information. It is hypothesized
that rest allows for superior consolidation of new memories.
In rodents, rest periods promote hippocampal replay of a
recently travelled route, and this replay is thought to be
critical for memory consolidation and subsequent spatial
navigation. If rest boosts human memory by promoting
hippocampal replay/consolidation, then the beneficial effect
of rest should extend to complex (hippocampal) memory tasks,
for example, tasks probing associations and sequences. We
investigated this question via a virtual reality route
memory task. Healthy young participants learned two routes
to a $100\%$ criterion. One route was followed by a 10-min
rest and the other by a 10-min spot the difference game. For
each learned route, participants performed four delayed
spatial memory tests probing: (i) associative
(landmark-direction) memory, (ii) cognitive map formation,
(iii) temporal (landmark) order memory, and (iv) route
memory. Tests were repeated after 7 days to determine any
long-term effects. No effect of rest was detected in the
route memory or cognitive map tests, most likely due to
ceiling and floor effects, respectively. Rest did, however,
boost retention in the associative memory and temporal order
memory tests, and this boost remained for at least 7 days.
We therefore demonstrate that the benefit of rest extends to
(spatial) associative and temporal order memory in humans.
We hypothesise that rest allows superior
consolidation/hippocampal replay of novel information
pertaining to a recently learned route, thus boosting new
memories over the long term.},
