“…These results also add to recent research focused on understanding whether memories of repeated life experiences should be considered a form of semantic memory or a form of episodic memory (Grilli and Verfaellie, 2015;Renoult et al, 2012;Rubin and Umanath, 2015). Based on the findings of this study and our prior work (Grilli and Verfaellie, 2015), we propose that repeated life experiences may be stored both as episodic-like personal memories and as personal knowledge in the form of autobiographical facts.…”

“…A challenge for future cognitive neuroscience research, therefore, will be to determine which of the other brain regions within this network support experience-near autobiographical facts, experience-far autobiographical facts, or both. In addition to clarifying the neural bases of autobiographical facts, such research could elucidate whether autobiographical facts are unique in spanning both episodic and semantic components in the organizational framework of personal memory (Renoult et al, 2012).…”

This paper addresses the idea that there may be two types of autobiographical facts with distinct cognitive and neural mechanisms: "Experience-near" autobiographical facts, which contain spatiotemporal content derived from personal experience and thus depend on the medial temporal lobe (MTL) for retrieval, and "experience-far" autobiographical facts, which are abstract memories and thus rely on neocortical brain regions involved in retrieval of general semantic memory. To investigate this conceptual model of autobiographical fact knowledge, we analyzed the nature of autobiographical facts that were generated by 8 individuals with MTL amnesia and 12 control participants in a recent study of identity and memory [Grilli, M.D., & Verfaellie, M. (2015). Supporting the self-concept with memory: insight from amnesia. Social Cognitive and Affective Neuroscience, 10, 1684-1692]. Results revealed that MTL amnesic participants generated fewer experience-near autobiographical facts than controls. Experience-far autobiographical fact generation was not impaired in amnesic participants with damage restricted to the MTL, but there was preliminary evidence to suggest that it may be impaired in amnesic participants with damage to the MTL and anterior lateral temporal lobe. These results support a cognitive and neural distinction between experience-near and experience-far autobiographical facts and have implications for understanding the contribution of autobiographical fact knowledge to self-related cognition.

“…Recent advances have suggested that in fact some types of semantic AM (e.g. repeated events, autobiographical facts containing spatiotemporal content) are closer to episodic memory than to semantic memory, in terms of both phenomenological experience at the time of retrieval, and the brain areas that are implicated (Grilli & Verfaellie, 2016;Renoult et al, 2012). Accordingly, one might question the importance of a strict definition of episodic AM, particularly in older age.…”

“…Note, however, that not all instances of memory or future thinking can be strictly classified as either episodic or semantic. For instance, personal semantic knowledge (15) is not associated with a specific episode (e.g., I am a good basketball player) and may be projected forward into the future (e.g., I want to play professional basketball in the future). As with personal semantic knowledge, such hybrid forms of episodic and semantic future thinking are not strictly episodic, in that they do not refer to a specific episode, and they are not strictly semantic.…”

Prospection-the ability to represent what might happen in the future-is a broad concept that has been used to characterize a wide variety of future-oriented cognitions, including affective forecasting, prospective memory, temporal discounting, episodic simulation, and autobiographical planning. In this article, we propose a taxonomy of prospection to initiate the important and necessary process of teasing apart the various forms of future thinking that constitute the landscape of prospective cognition. The organizational framework that we propose delineates episodic and semantic forms of four modes of future thinking: simulation, prediction, intention, and planning. We show how this framework can be used to draw attention to the ways in which various modes of future thinking interact with one another, generate new questions about prospective cognition, and illuminate our understanding of disorders of future thinking. We conclude by considering basic cognitive processes that give rise to prospective cognitions, cognitive operations and emotional/motivational states relevant to future-oriented cognition, and the possible role of procedural or motor systems in future-oriented behavior.prospection | simulation | prediction | intention | planning
