Autobiographical memories play important roles in the development of the self and identity by grounding the self in rich, meaningful experiences. In the present study, we explored whether there is a specific type of autobiographical memories tied to religious belief; namely, belief-related memories. We compared belief-related memories with important and word-cued memories across five religions. We found belief-related memories were characterised as important, positive, intense, vivid, and frequently retrieved. The characteristics of belief-related memories were markedly different from word-cued memories, and they also differed from important memories on several variables. Compared with important memories, belief-related memories were rated as less prevalent, less important, less scripted, and showed a different distribution across the life span. The temporal distributions of belief-related memories varied across religions and showed no reminiscence bump as opposed to important memories and word-cued memories. Our findings suggest belief-related memories form a distinct category of autobiographical memories, consistent with the self being multidimensional and with different types of memories supporting distinct aspects of the self.
