Abstract Influential research has focused on identifying the common neural and behavioural substrates underlying episodic memory (the re-experiencing of specific details from past experiences) and spatial cognition, with some theories proposing that these are supported by the same mechanisms. However, the similarities and differences between these two forms of memory in humans require further specification. We used an individual-differences approach based on self-reported survey data collected in a large online study (n = 7,487), focusing on autobiographical episodic memory and spatial navigation and their relationship to object and spatial imagery abilities. Multivariate analyses replicated prior findings that autobiographical episodic memory abilities dissociated from spatial navigational abilities. Considering imagery, episodic autobiographical memory overlapped with imagery of objects, whereas spatial navigation overlapped with a tendency to focus on spatial schematics and manipulation. These results suggest that trait episodic autobiographical memory and spatial navigation correspond to distinct mental processes. Keywords Autobiographical memory . Episodic memory . Navigation .

Introduction An influential body of animal and human research has investigated the overlapping neural and behavioural substrates of episodic memory (i.e., the recall and re-experiencing of details from past events with a specific spatiotemporal context; Tulving, 1972, 2002) and spatial cognition. This work began with Tolman's (1948) conceptualization of a cognitive map, used in spatial navigation and in guiding cognitive behaviour more broadly. Theoretical and experimental work in this field Electronic supplementary material The online version of this article (https://doi.org/10.3758/s13421-020-01093-7) contains supplementary material, which is available to authorized users. * Carina L.

has proliferated in the past decade, particularly in trying to reconcile the role of the hippocampus in both memory and spatial cognition (Buzsáki & Moser, 2013; Collin, Milivojevic, & Doeller, 2017; Ekstrom & Ranganath, 2018; Schiller et al., 2015). These studies seek to provide an integrative framework for how the hippocampus’s critical roles in both spatial and episodic memory can be explained using the same fundamental processes. Cognitive map theory posits that the brain builds a unified representation of the spa
