Virtual Mirror and Beyond: The Psychological Basis for Avatar Embodiment via a Mirror

In virtual reality (VR), a virtual mirror is often used to display the VR avatar to the user for enhancing the embodiment. The reflected image of the synchronization of the virtual body with the user’s movement is expected to be recognized as the user’s own reflection. In addition to the visuo-motor synchrony, there are some mirror reflection factors that are probably involved in avatar embodiment. This paper reviews literature on the psychological studies that involve mirror-specific self-identification and embodied perception to clarify how the reflected image of the virtual body is embodied. Furthermore, subjective misconceptions about mirror reflections reported in naïve optics have also been reviewed to discuss the potential of virtual mirror displays to modulate avatar embodiment.

From Johann to Maurice: Science and Expression in the Philosophical Praxis of Medicine

Phenomenology’s return to lived experience and “to the things themselves” is often contrasted with the synthesized perspective of science and its “view from nowhere.” The extensive use of neuropsychological case reports in Merleau-Ponty’s Phenomenology of Perception, however, suggests that the relationship between phenomenology and science is more complex than a sheer opposition, and a fruitful one for the praxis of medicine. Here, I propose a new reading of how Merleau-Ponty justifies his use of Adhémar Gelb and Kurt Goldstein’s reports on Johann Schneider for his phenomenology of embodied perception. I argue that for Merleau-Ponty these neuropsychological case reports represent a coherent deformation of the intercorporeally expressed existence of Schneider that through speech fall again onto the common ground of perception, thereby allowing Merleau-Ponty to understand, in the equivalent sense delivered by language, Schneider’s total being and fundamental illness. I then discuss what Merleau-Ponty’s method implies for a phenomenological praxis of medicine, and for the role of science in this praxis.

“Our eyes are sentinels unto our judgments”: Embodied Perception in The Changeling

This essay argues that Thomas Middleton and William Rowley's The Changeling (1622) draws on debates about sense perception in the period to interrogate the effects of dramatic representation. After a brief overview of early modern perceptual theory, this essay demonstrates that the play's villain, De Flores, manipulates other characters’ perception through language. In fact, De Flores uses theatrical language to manipulate how other characters perceive their environment, indicating the theater's ability to manipulate audiences. By affecting how characters perceive, De Flores affects other characters’ ability to process and react to their environment, which impedes their judgment. The essay argues that much of The Changeling's dramatic action unfolds through a conflict between two models of perception—presentational and representational—that undergird much of the play's dramatic conflict. In the play, pervasive anxiety about judgment, particularly how perception affects judgment, is structured around the distinction between these two models of perception. Considering the play alongside representational and presentational models indicates how early modern dramatists engage with intellectual theories to consider how representation works and how spaces are experienced. In this way, the theater refracts and dramatizes theories about perception.

Who Needs Sensory Education?

Customarily, reflections on the need to educate sensory and bodily enactments with the world, take for granted that it is the child who must be educated. However, the educational passage of becoming 'rational' and 'grown up' often leaves the adult divorced from her own embodied self. As part of my engagement with childism (conf. Wall in Ethics in light of childhood, Georgetown University Press, Washington, 2010; The child as natural phenomenologist. Primal and primary experience in Merleau-Ponty’s psychology, Northwestern University Press, Evanston, 2013; Child Geogr, 2019, https://doi.org/10.1080/14733285.2019.1668912) in this article, I ask: Who needs sensory education? In response, I propose that it is adults who need sensory education more than their temporal others (Beauvais, in: Spyrou S, Rosen R, Cook DT (eds) Reimagining childhood studies, Bloomsbury Academic, London, pp 57–74 2018) i.e. children. As Merleau-Ponty has shown, the richness of embodied perception that children experience, is relatively distant for adults (Bahler in Child Philos 11:203–221, 2015; Welsh in The child as natural phenomenologist. Primal and primary experience in Merleau-Ponty’s psychology, Northwestern University Press, Evanston, 2013). The particular lived-experience I reflect on is the sense of temporality. Accompanied by two distinct, yet interconnected examples of encounters with Baby Ole and Captain Duke, I suggest that being-with-children can enable philosophical clearings for adults to re-cognise plural temporalities, as opposed to a singular clock-time perception of Time. (The preposition with is used in the sense of the Norwegian hos or German bei, whereby an adult intentionally positions herself as a guest in a child's world.)

Immersion and Empathy

The aim of this chapter is to investigate histospheres as multi-immersive perceptual spaces that not only model a historical world but also profoundly influence our conceptions and interpretations of history. In this context, the first section examines the role of aesthetically modeled atmospheres and the moods they evoke. The second section builds on this examination by considering filmic space. Filmic atmospheres and spatial figurations of movement bring us physically and mentally closer to the action of the film. Another potent mechanism of perspectivation is film characters, and so the third section focuses on imaginative empathy with the characters who inhabit a film’s historical world. In combination with film experience as a mode of embodied perception, this inner perspective provokes interpretations and evaluations that we can extend to the filmic depiction’s historical references.

Social Active Inference

The free energy principle and its corollary, active inference, were introduced by Karl Friston as an explanation embodied perception and action in neuroscience, and since, it has been used to address many other issues in different fields mainly related to cognitive science like learning, optimal decision, or interpersonal inference. Negotiation is a process where each negotiator has conflicting motivation is aiming to maximize his utility and where agreement is reached when the opposing interests are balanced. The purpose of this chapter is to illustrate how the free energy principle might be used through active inference in modeling a negotiation process based on an example of real life. The work is an attempt to bring together a dynamic logic framework with appropriate operators to consider motivation among agents on one hand and the active inference framework on the other hand.
