Previous fMRI work in our lab has
examined the effect of novelty on
future event simulation with a
repetition suppression paradigm1.
We found that repetitions
decrease reaction times for event
construction, as well as producing
an fMRI adaptation effect in a
number of regions recruited by
These findings were attributed to the effects of
novelty inherent to imagining future scenarios.
It is not clear if these effects are specific to the
repetition of future events or if they would occur
when repeatedly recalling past events.
To this end, we conducted an adjusted behavioural
