How are we to understand the phenomenology of imagining? Attempts to answer this question often invoke descriptors concerning the “vivacity” or “vividness” of our imaginative states. Not only are particular imaginings often phenomenologically compared and contrasted with other imaginings on grounds of how vivid they are, but such imaginings are also often compared and contrasted with perceptions and memories on similar grounds. Yet however natural it may be to use “vividness” and cognate terms in discussions of imagination, it (...) does not take much reflection to see that these terms are ill understood. In this paper, I review both some relevant empirical literature as well as the philosophical literature attempt to get a handle on what it could mean, in an imaginative context, to talk of vividness. As I suggest, this notion ultimately proves to be so problematic as to be philosophically untenable. (shrink)

The notion of subjective vividness plays a fundamental role in comparing different conscious experiences, yet it is poorly understood and lacks proper definition. Philosophical reflection on this topic is especially scarce. This article proposes a novel account of vividness arguing that its standard operationalisation in psychology conflates two major modality‐general dimensions along which experiences vary—subjective intensity and subjective specificity—which themselves are determined by further modality‐specific factors. The article identifies the neural underpinnings of these factors in the visual domain, (...) demonstrates the unificatory power of the account, and argues that vividness is part of the content of perception.

Imaginings are often characterized in terms of vividness. However, there is little agreement in the philosophical literature as to what it amounts to and how to even investigate it. In this paper, we propose a natural kind methodology to study vividness and suggest treating it as a homeostatic property cluster with an underlying nature that explains the correlation of properties in that cluster. This approach relies on the empirical research on the vividness of mental imagery and contrasts (...) with those accounts that treat vividness as an explanatory primitive and with those that attempt to provide a definition. We apply the natural kind methodology to make several substantive claims about the vividness of mental imagery. First, we will argue that it forms a homeostatic property cluster, in that it is reliably correlated with, but not defined by, some properties, such as the level of detail, clarity, perception-likeness and intensity. In arguing for this claim, we also show how the cluster can be modified in the light of empirical research by complementing it with a correlation between vividness and familiarity. Second, we will argue that these correlations can be explained by an underlying property at the architectural level; i.e., the availability of stored sensory information for the elaboration of a mental image.

: Sinhababu’s Humean Nature contains many interesting and important ideas, but in this short commentary I focus on the idea of vivid representations. Sinhababu inherits his idea of vivid representations from Hume’s discussions, in particular his discussion of calm and violent passions. I am sympathetic to the idea of developing Hume’s insight that has been largely neglected by philosophers. I believe that Sinhababu and Hume are on the right track. What I do in this short commentary is to raise some (...) questions about the details. The aim of asking these questions is not to challenge Sinhababu’s proposal, but rather to point at some interesting issues arising out of his proposal. The questions are about the nature of vividness, the effects of vivid representations, and Sinhababu’s account of alief cases. Keywords: Vivid Representation; Desire; Procrastination; Akrasia; Alief Le rappresentazioni vivide e i loro effetti Riassunto: Humean Nature di Neil Sinhababu contiene molte idee interessanti e importanti; tuttavia in questo breve commento intendo concentrarmi sulle rappresentazioni vivide. Sinhababu eredita l’idea di rappresentazione vivida dalle analisi di Hume, in particolare dall’analisi delle passioni calme e violente. Condivido l’intento di sviluppare questa intuizione di Hume, ampiamente trascurata dai filosofi. Credo che Sinhababu e Hume siano sulla strada giusta. Quanto intendo fare in questo breve commento è sollevare alcune questioni di dettaglio, il cui fine non è quello di mettere in discussione la proposta di Sinhababu, quanto piuttosto di indicare alcuni punti interessanti che emergono dalla sua proposta. Le mie questioni investono la natura della vividezza, gli effetti delle rappresentazioni vivide e la descrizione di Sinhababu dei casi di alief.

Brain-computer interfaces are communication bridges between a human brain and external world, enabling humans to interact with their environment without muscle intervention. Their functionality, therefore, depends on both the BCI system and the cognitive capacities of the user. Motor-imagery BCIs rely on the users’ mental imagination of body movements. However, not all users have the ability to sufficiently modulate their brain activity for control of a MI-BCI; a problem known as BCI illiteracy or inefficiency. The underlying mechanism of this phenomenon (...) and the cause of such difference among users is yet not fully understood. In this study, we investigated the impact of several cognitive and psychological measures on MI-BCI performance. Fifty-five novice BCI-users participated in a left- versus right-hand motor imagery task. In addition to their BCI classification error rate and demographics, psychological measures including personality factors, affinity for technology, and motivation during the experiment, as well as cognitive measures including visuospatial memory and spatial ability and Vividness of Visual Imagery were collected. Factors that were found to have a significant impact on MI-BCI performance were Vividness of Visual Imagery, and the personality factors of orderliness and autonomy. These findings shed light on individual traits that lead to difficulty in BCI operation and hence can help with early prediction of inefficiency among users to optimize training for them. (shrink)

The vividness of mental imagery is epistemically relevant. Intuitively, vivid and intense memories are epistemically better than weak and hazy memories, and using a clear and precise mental image in the service of spatial reasoning is epistemically better than using a blurry and imprecise mental image. But how is vividness epistemically relevant? I argue that vividness is higher-order evidence about one’s epistemic state, rather than first-order evidence about the world. More specifically, the vividness of a mental (...) image is higher-order evidence about the amount of first-order information one has about its subject matter. When vividness is sufficiently low, it can give one reason to doubt the epistemic basis of the mental image and thereby act as a defeater. This account has important implications for theorizing about the epistemic roles of memory, imagination, mental imagery, and phenomenal consciousness. (shrink)

I argue that the Doctrine of Double Effect is accepted because of unreliable processes of belief-formation, making it unacceptably likely to be mistaken. We accept the doctrine because we more vividly imagine intended consequences of our actions than merely foreseen ones, making our aversions to the intended harms more violent, and making us judge that producing the intended harms is morally worse. This explanation fits psychological evidence from Schnall and others, and recent neuroscientific research from Greene, Klein, Kahane, and Schaich (...) Borg. It explains Mikhail and Hauser’s “universal moral grammar” and an interesting phenomenon about Double Effect cases noted by Bennett. When unequally vivid representations determine our decisions, we typically misjudge the merits of our options and make mistakes. So if Double Effect is a product of unequal vividness, it is likely to be mistaken. This argument, I claim, fits Berker’s specifications for good empirically grounded arguments in ethics. (shrink)

Several studies have shown a significant relationship between smelling and olfactory imagery abilities. The primary aim of the present study was to validate a French version of the Vividness of Olfactory Imagery Questionnaire. The secondary aim was to investigate its capability to differentiate individuals with smell loss from healthy individuals. After having elaborated a French translation of the VOIQ, we evaluated olfactory imagery abilities of 387 French participants who anonymously self-completed the fVOIQ: 121 pathologic individuals, 244 normosmic individuals, and (...) 22 fragrance experts. Significant split-half reliability as expressed by Spearman correlation coefficients for the global sample, as well as for each group separately, indicated the excellent internal consistency of the fVOIQ. Moreover, results revealed a significant effect of the smelling ability group on fVOIQ score, suggesting that daily olfactory stimulation is fundamental to maintaining the ability to create a vivid image and that severe loss of smell may result in progressive impairment of olfactory imagery. Our fVOIQ and the original English version seemingly have similarly high benefit in differentiating experts and normosmic individuals based on their olfactory imagery ability. Moreover, the fVOIQ seems capable of differentiating individuals with loss of smell from healthy individuals. These findings demonstrate the reliability and validity of the fVOIQ, and its capability to differentiate individuals’ smelling ability according to their olfactory imagery ability. (shrink)

One central brand of representationalism claims that the specific phenomenal character of an experience is fully determined by its content. A challenge for this view is that cognitive and perceptual experiences sometimes seem to have the same representational content while differing in phenomenal character. In particular, it might seem that one can have faint imagery experiences or conscious thoughts with the same contents as vivid perceptual experiences. This paper argues that such cases never arise, and that they are probably metaphysically (...) impossible. I also suggest a fully representational account of differences in vividness between phenomenal experiences. (shrink)

This paper argues that we should distinguish two different kinds of imaginative vividness: vividness of mental images and vividness of imaginative experiences. Philosophy has focussed on mental images, but distinguishing more complex vivid imaginative experiences from vivid mental images can help us understand our intuitions concerning the notion as well as the explanatory power of vividness. In particular, it can help us understand the epistemic role imagination can play on the one hand and our emotional engagement (...) with literary fiction on the other hand. (shrink)

This paper examines the topic of Yogācāra idealism through a little studied Buddhist meditation manual, the so-called ‘Yogalehrbuch’ or ‘Qizil Yoga Manual’, a primarily Buddhist Sarvāstivāda Abhidharma text with Mahāyāna Yogācāra strands. What does this unique Central Asian text say about Buddhist meditation practices called yogācāra or yoga? It centres on methods of vivid visualization that are somewhat specific to the Central Asian region of Kucha on the Silk Road. To understand the Manual’s practice and definition of yogic meditation, this (...) paper considers how some of the hyper-real visualizations in the dhātuprayoga section relate the mind to reality and whether Yogācāra meditation can be said to propose idealism as a metaphysical theory about the nature of reality. The paper also asks whether neurocognitive research insights can be useful in understanding what some regard as a ‘hallucination-like’ quality of some visualizations, which destabilise distinctions between appearances and reality. Furthermore, it argues that analyzing the materiality of meditation, particularly the environment of the cave, helps us to better understand the text’s techniques of yogic visualization. The paper concludes that the ‘Qizil Yoga Manual’ facilitates soteriological idealism and suggests that factoring in the material contexts of meditation is useful, both in deciphering the text’s meditation methods and in discussing the metaphysical theory of idealism.

Mead affronta il tema dell’utopia a partire dal contributo che l’antropologia e la comparazione tra culture possono offrire nell’identificare il ruolo che la visione utopica deve svolgere all’interno della cultura e della società. Mead nota come l’immaginazione umana si sia sempre rivelata molto più fertile nella formulazione distopica, piuttosto che nella positiva elaborazione utopica. Il problema della carenza di particolari e di definizione propria delle immagini utopiche è tematizzata in modo particolare. Vengono infine suggerite delle linee future di impostazione del (...) problema con particolare riferimento al lavoro antropologico, allo studio dell’immaginazione nell’infanzia e al problema della separazione tra scienza e studi umanistici.Mead faces the problem of Utopia along the perspectives of anthropology and comparison between cultures, trying to define the role of utopian visions within culture and society. Mead points out that human imagination has always been more fertile in the formulation of dystopian rather than utopian visions. The problem of the lack of vivacity and details of utopian visions is discussed in detail. Finally, some possible future lines of research are developed, including anthropological work, studies on children’s imagination, and the problem of the cultural separation between science and humanities.

Terrorism researchers have long discussed the role of psychology in the radicalization process. This work has included research on the respective roles of individual psychological traits and responses to terrorist propaganda. Unfortunately, much of this work has looked at psychological traits and responses to propaganda individually and has not considered how these factors may interact. This study redresses this gap in the literature. In this experiment (N = 268), participants were measured in terms of their narcissism, Machiavellianism, subclinical psychopathy, and (...) everyday sadism—collectively called the Dark Tetrad. Participants were then exposed to a vivid or nonvivid terrorist narrative (or a control message). Results indicate that Machiavellianism interacts with both narrative exposure and narrative vividness to amplify the persuasive effect of terrorist narratives. Neither narcissism, subclinical psychopathy, nor everyday sadism had such an effect. These results highlight the importance of considering the psychological traits of audiences when evaluating proclivity for radicalizationviapersuasion by terrorist narratives. (shrink)

The differential activation hypothesis (DAH; Teasdale, 1988) proposes that individuals who are vulnerable to depression can be distinguished from non-vulnerable individuals by the degree to which negative thoughts and maladaptive cognitive processes are activated during sad mood. While retrieval of negative autobiographical memories is noted as one such process, the model does not articulate a role for deficits in recalling positive memories. Two studies were conducted to compare the autobiographical memory characteristics of never-depressed and formerly depressed individuals following a sad (...) mood induction. In Study 1, features of negative memories of never-depressed and formerly depressed individuals did not differ, either in neutral or sad mood. For positive memories, groups did not differ in neutral mood, but following a sad mood induction, formerly depressed individuals rated their positive memories as less vivid than their never-depressed counterparts. Study 2 examined positive autobiographical memory features more comprehensively and replicated the finding that in a sad mood formerly depressed individuals recalled less vivid positive memories than never-depressed controls. These findings suggest that the phenomenological features of positive memories could represent an important factor in depressive vulnerability, and, more broadly, that depression may be associated with a deficit in the processing of positive material.

John Martin Fischer’s Death, Immortality, and Meaning in Life puts forth a view that individual experiences could provide us with sources of endless fascination, motivation, and value if only we could live forever to continue to enjoy them. In this article I advocate for more caution about embracing this picture by pointing to three points of tension in Fischer's book. First, I argue that taking meaningfulness in life to be holistic is not compatible with the view immortal lives would be (...) recognizably humanlike. Next, I interrogate Fischer’s claim that that worries about boredom in immortal lives are predicated on the false view that our pursuits are compelling to us because we value them instrumentally, showing that he relies on a more controversial view of the value of our pursuits. Finally, I argue that Fischer’s naturalistic reinterpretation of the value of Near-Death experiences falls somewhat short of capturing their poignancy. Given Fischer’s seeming acknowledgment that what we get from an experience is sometimes ineffable, I argue that he ought to be less skeptical that a genuine Near-Death Experience would give the person experiencing it some (defeasible) evidence of the supernatural.

It has been claimed that the ability to remember the past and the ability to project oneself into the future are intimately related. We sought support for this proposition by examining whether individual differences in dimensions that have been shown to affect memory for past events similarly influence the experience of projecting oneself into the future. We found that individuals with a higher capacity for visual imagery experienced more visual and other sensory details both when remembering past events and when (...) imagining future events. In addition, individuals who habitually use suppression to regulate their emotions experienced fewer sensory, contextual, and emotional details when representing both past and future events, while the use of reappraisal had no effect on either kind of events. These findings are consistent with the view that mental time travel into the past and into the future relies on similar mechanisms. (shrink)
