Mnemicity vs. Temporality: Distinguishing between components of episodic representations
Human beings regularly 'mentally travel' to past and future times in memory and imagination. In theory, whether an event is remembered or imagined (its ‘mnemicity’) underspecifies whether it is oriented towards the past or the future (its ‘temporality’). However, it remains unclear to what extent the temporal orientation of such episodic simulations is cognitively represented separately from their status as memories or imagination. To address this question, we investigated whether episodic simulations are more easily distinguishable in memory by virtue of their temporal orientation or their mnemicity. In three experiments (N = 360), participants were asked to generate and later recall events differing along the lines of temporal orientation (past/future) and mnemicity (remembered/imagined). Across all of our experiments, we consistently found that participants were more likely to confuse in recall event simulations that shared the same temporal orientation rather than the same mnemicity. These results show that the temporal orientation of episodic representations can be cognitively represented separately from their mnemicity and have implications for debates about the role of temporality in episodic simulation.
