AbstractWe assessed how self-motion affects the visual representation of the self. We constructed a novel virtual reality experiment that systematically varied an avatar’s motion and also biological sex. Participants were presented with pairs of avatars that visually represented the participant (“self avatar”), or another person (“opposite avatar”). Avatar motion either corresponded with the participant’s motion, or was decoupled from the participant’s motion. The results show that participants identified with i) “self avatars” over “opposite avatars”, ii) avatars moving congruently with self-motion over incongruent motion, and importantly iii) identification with the “opposite avatar” over the “self avatar” when the opposite avatar’s motion was congruent with self-motion. Our results suggest that both self-motion and biological sex are relevant to the body schema and body image and that congruent bottom-up visual feedback of self-motion is particularly important for the sense of self and capable of overriding top-down self-identification factors such as biological sex.

Language Grounding

Human language is inherently embodied and grounded in sensorimotor representations of the self and the world around it. This suggests that the body schema and ideomotor action-effect associations play an important role in language understanding, language generation, and verbal/physical interaction with others. There are computational models that focus purely on non-verbal interaction between humans and robots, and there are computational models for dialog systems that focus only on verbal interaction. However, there is a lack of research that integrates these approaches. We hypothesize that the development of computational models of the self is very appropriate for considering joint verbal and physical interaction. Therefore, they provide the substantial potential to foster the psychological and cognitive understanding of language grounding, and they have significant potential to improve human-robot interaction methods and applications. This review is a first step toward developing models of the self that integrate verbal and non-verbal communication. To this end, we first analyze the relevant findings and mechanisms for language grounding in the psychological and cognitive literature on ideomotor theory. Second, we identify the existing computational methods that implement physical decision-making and verbal interaction. As a result, we outline how the current computational methods can be used to create advanced computational interaction models that integrate language grounding with body schemas and self-representations.

Participants were presented with pairs of avatars that visually represented the participant (‘self-avatar’), or another person (‘opposite avatar’). Avatar motion either corresponded with the participant’s motion, or was decoupled from the participant’s motion. The results show that participants identified with (i) ‘self-avatars’ over ‘opposite-avatars’, (ii) avatars moving congruently with self-motion over incongruent motion, and importantly (iii) with the ‘opposite avatar’ over the ‘self-avatar’ when the opposite avatar’s motion was congruent with self-motion.

Body Ego

Disturbances of ego, self-concept and body-image have always been regarded as central in the psychopathology of schizophrenia. The passivity phenomena, automatisme superieur of the French authors, are indeed very common in this disease. There is a disturbance of the self which is shown in depersonalization and in feelings of influence and passivity. The boundaries of the self become loose or blurred and the patient may feel, for example, that parts of his body do not belong to him or that he is part of the plants, animals, clouds, other people or of the whole world and that they are part of him. He may feel at one with the whole of mankind. Self-concept is closely related to what has been termed “body image” or “perceived body”. Head (29, 30) has shown that what he called “body schema” is very important for motor co-ordination and performance of purposeful movements and also for orientation in space. Schilder (53) in his monograph has analysed the problem of body-image in great detail. He has found in the idea of the body image the basis for the body or physical ego. He follows Head in stating that the body image consists of the proprioceptions of the whole body and that it changes with the body's varying postures. Yet neither Head's body schema nor Schilder's body image are identical with the body ego. The body schema represents the constant mental knowledge of one's body; the body image is the changing presentation of the body in one's mind. Throughout the changes of the body image there is an awareness of continuity of one's body, a sense of basic identity and oneness. This constitutes the bodily or physical ego. The body ego in its turn is the basis of a wider “self” which can be called self-concept or selfhood. This self-concept or selfhood contains, in addition to the awareness of the continuity and the identity of one's own body in spite of its constant change, the awareness of the continuity of one's self as a person in spite of constantly changing relationship with the external world, and in spite of the playing and taking different “roles” in social interactions. According to Mead (38) and Coutu (16), selfhood is a social phenomenon and emerges only through interaction with other people, through “taking their roles” and viewing oneself from their point of view.

The essay discusses selected poems from Thomas Hardy's vast body of poetry, focusing on representations of the self and the world. Employing Maurice Merleau-Ponty's concepts such as the body-subject, wild being, flesh, and reversibility, the essay offers an analysis of Hardy's poems in the light of phenomenological philosophy. It argues that far from demonstrating ‘cosmic indifference’, Hardy's poetry offers a sympathetic vision of interrelations governing the universe. The attunement with voices of the Earth foregrounded in the poems enables the self's entanglement in the flesh of the world, a chiasmatic intertwining of beings inserted between the leaves of the world. The relation of the self with the world is established through the act of perception, mainly visual and aural, when the body becomes intertwined with the world, thus resulting in a powerful welding. Such moments of vision are brief and elusive, which enhances a sense of transitoriness, and, yet, they are also timeless as the self becomes immersed in the experience. As time is a recurrent theme in Hardy's poetry, this essay discusses it in the context of dwelling, the provisionality of which is demonstrated in the prevalent sense of temporality, marked by seasons and birdsong, which underline the rhythms of the world.

The book’s epilogue explores the place of musical portraiture in the context of posthumous depictions of the deceased, and in relation to the so-called posthuman condition, which describes contemporary changes in the relationship of the individual with such aspects of life as technology and the body. It first examines Alfred Hitchcock’s Vertigo to view how Bernard Herrmann’s score relates to issues of portraiture and the depiction of the identity of the deceased. It then considers the work of cyborg composer-artist Neil Harbisson, who has aimed, through the use of new capabilities of hybridity between the body and technology, to convey something akin to visual likeness in his series of Sound Portraits. The epilogue shows how an examination of contemporary views of posthumous and posthuman identities helps to illuminate the ways music represents the self throughout the genre of musical portraiture.

AbstractSituational or persistent body fluid deficit (i.e., de- or hypo-hydration) is considered a significant health risk factor. Bioimpedance analysis (BIA) has been suggested as an alternative to less reliable subjective and biochemical indicators of hydration status. The present study aimed to compare various BIA models in the prediction of direct measures of body compartments associated with hydration/osmolality. Fish (n = 20) was selected as a biological model for physicochemically measuring proximate body compartments associated with hydration such as water, dissolved proteins, and non-osseous minerals as the references or criterion points. Whole-body and segmental/local impedance measures were used to investigate a pool of BIA models, which were compared by Akaike Information Criterion in their ability to accurately predict the body components. Statistical models showed that ‘volumetric-based’ BIA measures obtained in parallel, such as distance2/Rp, could be the best approach in predicting percent of body moisture, proteins, and minerals in the whole-body schema. However, serially-obtained BIA measures, such as the ratio of the reactance to resistance and the resistance adjusted for distance between electrodes, were the best fitting in predicting the compartments in the segmental schema. Validity of these results should be confirmed on humans before implementation in practice.
