Under normal circumstances, we experience that our center of awareness is located behind our eyes and inside our own body. To learn more about the perceptual processes that underlie this tight coupling between the spatial dimensions of our consciously perceived self and our physical body, we conducted a series of experiments using an ‘out-of-body illusion’. In this illusion, the conscious sense of self is displaced in the testing room by experimental manipulation of the congruency of visual and tactile information and (...) a change in the visual perspective. We demonstrate that when healthy individuals experience that they are located in a different place from their real body, they disown this body and no longer perceive it as part of themselves. Our findings are important because they reveal a relationship between the representation of self-location in the local environment and the multisensory representation of one’s own body. (shrink)

Presence research can tell us why we feel present in the real world and can experience presence while using virtual reality technology (and movies and games) but has strikingly less to say on why we feel present in the scenes described in a book. Just how is it that the wonderful tangible detail of the real world or the complexity of digital technology can be matched and even surpassed by a story in a paperback book? This paper identifies a range (...) of potential neurological solutions to this problem (and the “real world” and “dream” problems for good measure). We consider Jeannerod’s neural simulation of action, Grush’s emulation theory of representation and Rizzolatti’s work on mirror neurons as being candidate solutions to the “book problem”. We conclude by observing that these potential solutions further underline the “purpose” of presence is to act in the world whether it is real, virtual or solely in our imaginations. (shrink)

Abstract The idea of disembodied communication has received widespread discussion in the context of the various kinds of online interaction. Electronic mail is probably the purest form of text-based communication where interlocutors are present in mind rather than body. I argue that this online model provides a way of understanding and defending the possibility of a certain kind of public religious experience, contra the many critics of the very coherence of genuine religious experience. I introduce the concept of ‘telic possibility’, (...) a specific kind of modality, applying it to e-mail. I argue that we can reasonably move from the telic possibility of disembodied communication in mundane e-mail exchanges to the epistemic possibility of communication from a divine being in cases where the content of the messages is sufficiently extraordinary.

A common view about the phenomenology of episodic remembering has it that when we remember a perceptual experience, we can relive or re-experience many of its features, but not its characteristic presence. In this paper, we challenge this common view. We first say that presence in perception divides into temporal and locative presence, with locative having two sides, an objective and a subjective one. While we agree with the common view that temporal and objective locative presence cannot be relived in (...) remembering, we argue that subjective locative presence – the feeling of being immersed in a certain scene – can be so. Our argument for this claim starts by determining independently the underpinning mechanisms of subjective locative presence in quasi-perceptual imagination. These mechanisms are self-projection, imaginative pretence, and attentional focus. We then proceed to establish that they have been found to underpin conscious states of episodic remembering too. We conclude that episodic remembering can bring us to relive the subjective locative presence characteristic of a perceptual experience, and that the common view is mistaken. Our view – ‘mnemonic immersivism’ – has important consequences regarding the relationships between memory and imagination and the phenomenology of episodic remembering. (shrink)

"In this paper, I explore the ways that phenomenological concepts like intercorporeality and mutual incorporation offer new tools in trying to make sense of human experiences via mediating systems. In particular, I think about how the COVID-19 pandemic hastened a large population into mediated interactions, and what is lost, perhaps contingently or perhaps intrinsically, when human experiences are mediated in this way. I look to research in presence, skillful interaction, and enactive social cognition to argue that there remains something ineffable (...) or at least extremely hard to pin down about intercorporeality, and embodied togetherness has not yet been replicated in the mediating systems we currently embrace. Keywords: intercorporeality, participatory sense-making, mediating technologies, presence. ". (shrink)

The paper introduces a new model of telepresence. First, it criticises the standard model of presence as epistemic failure, showing it to be inadequate. It then replaces it with a new model of presence as successful observability. It further provides reasons to distinguish between two types of presence, backward and forward. The new model is then tested against two ethical issues whose nature has been modified by the development of digital information and communication technologies, namely pornography and privacy, and shown (...) to be effective.

In order to take advantage of the potential offered by the medium of virtual reality, it will be essential to develop an understanding of how to maximize the desirable experience of ‘presence’ in a virtual space (‘being there’), and how to minimize the undesirable feeling of ‘cybersickness’ (a constellation of discomfort symptoms experienced in virtual reality). Although there have been frequent reports of a possible link between the observer’s sense of presence and the experience of bodily discomfort in virtual reality, (...) the amount of literature that discusses the nature of the relationship is limited. Recent research has underlined the possibility that these variables have shared causes, and that both factors may be manipulated with a single approach. This review paper summarizes the concepts of presence and cybersickness and highlights the strengths and gaps in our understanding about their relationship. We review studies that have measured the association between presence and cybersickness, and conclude that the balance of evidence favours a negative relationship between the two factors which is driven principally by sensory integration processes. We also discuss how system immersiveness might play a role in modulating both presence and cybersickness. However, we identify a serious absence of high-powered studies that aim to reveal the nature of this relationship. Based on this evidence we propose recommendations for future studies investigating presence, cybersickness, and other related factors. (shrink)

Research in cognitive neuroscience and spatial presence suggests that human mental self-localization is tied to one place at a given point in time. In this study, we examined whether it is possible to feel localized at two distinct places at the same time. Participants were exposed to a virtual rollercoaster and they continuously judged to what extent they felt present in the immediate environment and in the mediated environment, respectively. The results show that participants distributed their self-localization to both environments, (...) and the two values added up to closely 100% over time. In addition, even though the judgments are highly idiosyncratic, they were almost perfectly inversely related. This indicates that individuals can distribute their self over two distinct places. These findings provide important insights about understanding of the human self-localization. (shrink)

Trust is central to our social lives in both epistemic and practical ways. Often, it is rational only given evidence for trustworthiness, and with that evidence is made available by communication. New technologies are changing our practices of communication, enabling increasing rich and diverse ways of ‘being there’, but at a distance. This paper asks: how does telepresent communication support evidence-constrained trust? In answering it, I reply to the leading pessimists about the possibility of the digital mediation of trust, Philip (...) Pettit and Hubert Dreyfus. I also rebut Media Richness Theory, which proposes a linear relationship between the volume of mediated information and the quality of communication. Positively, I develop a speech-act theory of digitally mediated communication, drawing on Austen’s identification of the illocutionary act. The choice of a particular technology of communication constitutes part of what is communicated, including a setting of the social ‘frame’, and thus the possibilities for trust to be sustained or eroded. How something is said is part of what it is that is said. (shrink)

Philosophers and cognitive scientists try to understand, from different perspectives, the nature of the experience of reality. Given this shared, interdisciplinary interest, it would be beneficial to have a coherent story about the experience of reality, in which there is reciprocal contribution from both philosophy and cognitive science. This paper wants to pave the way for this shared enterprise on the investigation of the experience of reality. I first distinguish between two indicators of reality. (1) The experience of availability to (...) motor interaction. (2) The experience of mind-independence. I then show how invoking an analysis of the results from vision science, concerning the visual mechanisms of stereopsis, which is related to the visual impression of a solid, three-dimensional world available to motor interaction, successfully provides a coherent description of the first indicator. Furthermore, I suggest that the analysis of the evidence about the first indicator is very informative in preparing the ground for the investigation of the second indicator. This is shown by discussing experimental evidence directly related to stereopsis, as well as some perceptual phenomena that are usually described by invoking the story from vision science about stereopsis. Thus, the epistemological analysis of the results from vision science on stereopsis, offered in this paper, is beneficial in a twofold manner, for the interdisciplinary enterprise aimed at understanding the experience of reality. It is explicitly beneficial in the description of the first indicator, and implicitly beneficial to understand the second indicator. Finally, it also suggests future research about their relation.

Recent developments in virtual reality technology raise a question about the experience of presence and immersion in virtual environments. What is immersion and what are the conditions for inducing the experience of virtual presence? In this paper, we argue that crucial determinants of presence are perception of affordances and sense of embodiment. In the first section of this paper, we define key concepts and introduce important distinctions such as immersion and presence. In the second and third sections, we respectively discuss (...) presence, immersion and their determinants in detail. In the fourth and fifth sections, we argue for the importance of perception of affordances and sense of embodiment in increasing the degree of presence. Finally, we show the consequences of our view and discuss possible future implications. (shrink)

In recent years, the field of virtual reality (VR) has shown tremendous advancements and is utilized in fields ranging from entertainment, scientific research, social networks, artistic creation as well as numerous approaches to employ VR for psychotherapy. While the use of VR in psychotherapy has been widely discussed, little attention has been given to the potential of this new medium for art therapy. Artistic expression in virtual reality is a novel medium which offers unique possibilities, extending beyond classical expressive art (...) mediums. Creation in virtual reality includes options such as three-dimensional painting, an immersive creative experience, dynamic scaling and embodied expression. In this perspective paper, we present the potentials and challenges of virtual reality for art therapy and outline basic principles for its implementation. We focus on the novel qualities offered by this creative medium (the virtual environment, virtual materials and unreal characteristics) and on the core aspects of virtual reality (such as presence, Immersivity, point of view and perspective) for the practice of art therapy.
