Humans are able to transcend the present and mentally travel to another time, place, or perspective. Mentally projecting ourselves backwards (i.e., episodic memory) or forwards (i.e., episodic foresight) in time are crucial characteristics of the human memory system. Indeed, over the past few years, episodic memory has been argued to be involved both in our capacity to retrieve our personal past experiences and in our ability to imagine and foresee future scenarios. However, recent theory and findings suggest that semantic memory (...) also plays a significant role in imagining future scenarios. We draw on Tulving’s definition of episodic and semantic memory to provide a critical analysis of their role in episodic foresight tasks described in the developmental literature. We conclude by suggesting future directions of research that could further our understanding of how both episodic memory and semantic memory are intimately connected to episodic foresight. (shrink)

Acting in the present in anticipation of the future is argued to be a behavioral correlate of mental time travel (MTT). Yet, it is important to consider how other future-directed behaviors figure into a theory of MTT and future thinking more broadly. Developmental science can help in this formulation.

Gilead et al.'s theory presupposes that traversing temporal, spatial, social, and hypothetical distances are largely interchangeable acts of mental travel that co-occur in human ontogeny. Yet, this claim is at odds with recent developmental data suggesting that children's reasoning is differentially affected by the dimension which they must traverse, and that different representational abilities underlie travel across different dimensions.
