That is, an appropriate experimental paradigm should contrast tasks that involve chronesthesia (e.g., remembering the past, imagining the future) with a task that is matched to the past and future tasks on nontemporal features, such as imagining oneself interacting with people and locations, without requiring ‘‘movement’’ in subjective time. Nyberg et al. (2010) scanned participants using fMRI during experimental tasks that, they contended, require chronesthesia—remembering a recent short walk along a familiar route or imagining a future short walk along the same route.
