An incoherent visualization is when aspects of different senses of a word are present in the same visualization. We describe and implement a new model of creating contextual coherence in the visual imagination called Coherencer, based on the SOILIE model of imagination. We show that Coherencer is able to generate scene descriptions that are more coherent than SOILIE's original approach as well as a parallel connectionist algorithm that is considered competitive in the literature on general coherence. We also show that (...) co-occurrence probabilities are a better association representation than holographic vectors and that better models of coherence improve the resulting output independent of the association type that is used. Theoretically, we show that Coherencer is consistent with other models of cognitive generation. In particular, Coherencer is a similar, but more cognitively plausible model than the C3 model of concept combination created by Costello and Keane. We show that Coherencer is also consistent with both the modal schematic indices of perceptual symbol systems theory and the amodal contextual constraints of Thagard's theory of coherence. Finally, we describe how Coherencer is consistent with contemporary research on the hippocampus, and we show evidence that the process of making a visualization coherent is serial. (shrink)

Recently, a view I refer to as “hypothetical continuism” has garnered some favour among philosophers, based largely on empirical research showing substantial neurocognitive overlaps between episodic memory and imagination. According to this view, episodically remembering past events is the same kind of cognitive process as sensorily imagining future and counterfactual events. In this paper, I first argue that hypothetical continuism is false, on the basis of substantive epistemic asymmetries between episodic memory and the relevant kinds of imagination. However, I then (...) propose and defend an alternative form of continuism, according to which episodic memory is continuous with a capacity I call “actuality-oriented imagination.” Because of the deep epistemic affinities between episodic memory and actuality-oriented imagination, it makes sense to think of them as cognitive processes of the same kind.

Episodic memory has been analyzed in a number of different ways in both philosophy and psychology, and most controversy has centered on its self-referential,autonoeticcharacter. Here, we offer a comprehensive characterization of episodic memory in representational terms and propose a novel functional account on this basis. We argue that episodic memory should be understood as a distinctive epistemic attitude taken toward an event simulation. In this view, episodic memory has a metarepresentational format and should not be equated with beliefs about the (...) past. Instead, empirical findings suggest that the contents of human episodic memory are often constructed in the service of the explicit justification of such beliefs. Existing accounts of episodic memory function that have focused on explaining its constructive character through its role in future-oriented mental time travel do justice neither to its capacity to ground veridical beliefs about the past nor to its representational format. We provide an account of the metarepresentational structure of episodic memory in terms of its role in communicative interaction. The generative nature of recollection allows us to represent and communicate the reasons why we hold certain beliefs about the past. In this process, autonoesis corresponds to the capacity to determine when and how to assert epistemic authority in making claims about the past. A domain where such claims are indispensable are human social engagements. Such engagements commonly require the justification of entitlements and obligations, which is often possible only by explicit reference to specific past events. (shrink)

This essay unites current philosophical thinking on imagination with a burgeoning debate in the philosophy of memory over whether episodic remembering is simply a kind of imagining. So far, this debate has been hampered by a lack of clarity in the notion of imagining at issue. Several options are considered and constructive imagining is identified as the relevant kind. Next, a functionalist account of episodic remembering is defended as a means to establishing two key points: first, one need not defend (...) a factive view of remembering in order to hold that causal connections to past experiences are essential to how rememberings are typed; and, second, current theories that equate remembering with imagining are in fact consistent with a functionalist theory that includes causal connections in its account of what it is to remember. This suggests that remembering is not a kind of imagining and clarifies what it would take to establish the contrary. (shrink)

Martin and Deutscher’s causal theory of remembering holds that a memory trace serves as a necessary causal link between any genuine episode of remembering and the event it enables one to recall. In recent years, the causal theory has come under fire from researchers across philosophy and cognitive science, who argue that results from the scientific study of memory are incompatible with the kinds of memory traces that Martin and Deutscher hold essential to remembering. Of special note, these critics observe, (...) is that a single memory trace can be shaped by multiple past experiences. This appears to prevent traces from underwriting Martin and Deutscher’s distinction between remembering an event and merely forming an accurate representation of it. This paper accepts such criticisms of the standard causal theory and, through considering the phenomenon forgetting through repetition, raises several others. A substantially revised causal theory is then developed, compatible with the thesis that individual memory traces are shaped by multiple past experiences. The key strategy is to conceive of episodic remembering not as the simple retrieval and projection of a static memory trace, but as a complex quasi-inferential process that makes use of multiple forms of information and cues—“prop-like” memory traces included—in generating the experience known as episodic remembering. When remembering is understood as a multi-componential process, there are a variety of ways in which a representation of the past may be appropriately causally dependent upon a prior experience of the event remembered.

This paper provides a novel argument for granting memory the status of a generative source of justification and knowledge. Memory can produce justified output beliefs and knowledge on the basis of unjustified input beliefs alone. The key to understanding how memory can generate justification and knowledge, memory generativism, is to bear in mind that memory frequently omits part of the stored information. The proposed argument depends on a broadly reliabilist approach to justification.

Involuntary autobiographical memories (IAMs) and déjà vu are phenomena that occur spontaneously in daily life. IAMs are recollections of the personal past, whereas déjà vu is defined as an experience in which the person feels familiarity at the same time as knowing that the familiarity is false. We present and discuss the idea that both IAMs and déjà vu can be explained as natural phenomena resulting from memory processing and, importantly, are both based on the same memory retrieval processes. Briefly, (...) we hypothesise that both can be described as “involuntary” or spontaneous cognitions, where IAMs deliver content and déjà vu delivers only the feeling of retrieval. We map out the similarities and differences between the two, making a theoretical and neuroscientific account for their integration into models of memory retrieval and how the autobiographical memory literature can explain these quirks of daily life and unusual but meaningful phenomena. We explain the emergence of the déjà vu phenomenon by relating it to well-known mechanisms of autobiographical memory retrieval, concluding that IAMs and déjà vu lie on a continuum. (shrink)

This paper investigates a capacity I call actuality-oriented imagining, by which we use sensory imagination in a way that's directed at representing the actual world. I argue that this kind of imagining is distinct from other, similar mental states in virtue of its distinctive content determination and success conditions. Actuality-oriented imagining is thus a distinctive cognitive capacity in its own right. Thinking about this capacity reveals that we should resist an intuitive tendency to think of the imagination’s primary function or (...) default mode as representing the non-actual or the fictional. Instead, the imagination is a cognitive faculty that often puts us in touch with the way things are in reality. (shrink)

I argue that our current practice of ascribing the term “ memory ” to mental states and processes lacks epistemic warrant. Memory, according to the “received view”, is any state or process that results from the sequential stages of encoding, storage and retrieval. By these criteria, memory, or its footprint, can be seen in virtually every mental state we are capable of having. This, I argue, stretches the term to the breaking point. I draw on phenomenological, historical and conceptual considerations (...) to make the case that an act of memory entails a direct, non-inferential feeling of re-acquaintance with one’s past. It does so by linking content retrieved from storage with autonoetic awareness during retrieval. On this view, memory is not the content of experience, but the manner in which that content is experienced. I discuss some theoretical and practical implications and advantages of adopting this more nuanced view of memory. -/-. (shrink)

Following the seminal work of Ingvar (1985. “Memory for the future”: An essay on the temporal organization of conscious awareness. Human Neurobiology, 4, 127–136), Suddendorf (1994. The discovery of the fourth dimension: Mental time travel and human evolution. Master’s thesis. University of Waikato, Hamilton, New Zealand), and Tulving (1985. Memory and consciousness. Canadian Psychology/Psychologie Canadienne, 26, 1–12), exploration of the ability to anticipate and prepare for future contingencies that cannot be known with certainty has grown into a thriving research enterprise. (...) A fundamental tenet of this line of inquiry is that future-oriented mental time travel, in most of its presentations, is underwritten by a property or an extension of episodic recollection. However, a careful conceptual analysis of exactly how episodic memory functions in this capacity has yet to be undertaken. In this paper I conduct such an analysis. Based on conceptual, phenomenological, and empirical considerations,I conclude that the autonoetic component of episodic memory, not episodic memory per se, is the causally determinative factor enabling an individual to project him or herself into a personal future.
