Knee proprioception deficits and neuroplasticity have been indicated following injury to the anterior cruciate ligament. Evidence is, however, scarce regarding brain response to knee proprioception tasks and the impact of ACL injury. This study aimed to identify brain regions associated with the proprioceptive sense of joint position at the knee and whether the related brain response of individuals with ACL reconstruction differed from that of asymptomatic controls. Twenty-one persons with unilateral ACL reconstruction of either the right or left knee, as (...) well as 19 controls matched for sex, age, height, weight and current activity level, performed a knee joint position sense test during simultaneous functional magnetic resonance imaging. Integrated motion capture provided real-time knee kinematics to activate test instructions, as well as accurate knee angles for JPS outcomes. Recruited brain regions during knee angle reproduction included somatosensory cortices, prefrontal cortex and insula. Neither brain response nor JPS errors differed between groups, but across groups significant correlations revealed that greater errors were associated with greater ipsilateral response in the anterior cingulate, supramarginal gyrus and insula. This is the first study to capture brain response using fMRI in relation to quantifiable knee JPS. Activated brain regions have previously been associated with sensorimotor processes, body schema and interoception. Our innovative paradigm can help to guide future research investigating brain response to lower limb proprioception. (shrink)

Philosophical considerations regarding experiential spatial content have focused on exteroceptive sensations presenting external entities, and not on interoceptive experiences that present states of our own body. A notable example is studies on interoceptive touch, in which it is argued that interoceptive tactile experiences have rich spatial content such that tactile sensations are experienced as located in a spatial field. This paper investigates whether a similarly rich spatial content can be attributed to experiences of acute, cutaneous pain. It is argued that (...) such experiences of pain do not have field-like content, as they do not present distance relations between painful sensations. (shrink)

Anorexia Nervosa (AN) is a psychiatric illness that presents a complex variety of perceptual alterations and somatic sensations. These alterations occur at the level of (1) bodily representations and (2) bodily experiences. The alterations are widespread, and they involve multiple cognitive functions. We reviewed the current literature linking the psychiatric literature on AN with the philosophical debate on the Cognitive Penetrability of Perception (CPP). We describe the alterations in perception, starting from the most widespread and studied, i.e., those concerning distortions (...) in the estimation of the dimensions of one's body (“dysmorphophobia” or “body image disturbance”) to then describe those of more recent analysis involving alterations in bodily experiences. Body image disturbances in AN have been linked to alexithymia, emotional dysregulation, and altered interoceptive awareness, highlighting the complex interaction between emotion, cognition, and perception in AN. We show how the recent debate on CPP can benefit from the empirical investigations in AN, and can, in turn, serve to outline new lines of research. (shrink)

Edited by Manos Tsakiris and Helena De Preester, (Oxford, Oxford University Press), 2019, 368 pages,To understand the nature of mind, cognitive scientists of all theoretical strands may benefit from considering experimental evidence of cognition (perception, attention, memory, etc.) alongside phenomenologies of (conscious) experiences and feelings-let's say, proprioceptive, exteroceptive, interoceptive, and bodily self-conscious. Roughly, the former dimension of scientific studies of mind seems to have found its legitimacy; however, at least, at first sight, the latter could still not be exonerated completely. (...) That is to say, as far as the scientifically evidence-based account of interoception is concerned, we will have come a long way towards buttressing its legitimacy. The Interoceptive Mind: From Homeostasis to Awareness (Tsakiris and De Preester, 2019) would be seen as a guide to scientific studies of interoception in all of the cases so far. In particular, the essays collected in this book shed light on multisensory integrations of interoceptive and exteroceptive feelings (and even self-conscious feelings) across widespread disciplines.As suggested in its title, the book addresses the difficulties of integrating various dimensions relevant to feelings-from the biological notion of self to the interoceptive origin of self-awareness. The book divides into four sections, and each chapter is worthy of careful attention.Part I, i.e., the first chapter introduces the histor... (shrink)

The psychology of ownership is rooted in self-ownership. The human brain has an evolved interoceptive sense of owning the body that supports self-ownership and the ownership of external things as extensions of the self-owning self. In this way, evolutionary neuroscience supports a Lockean liberal conception of equal natural rights rooted in natural self-ownership.

Depersonalization and derealization refer to states of dissociation in which one feels a sense of alienation in relation to one’s self and environment, respectively. Whilst transient episodes often diminish without treatment, chronic experiences of DP and DR may last for years, with common treatments lacking a strong evidence base for their efficacy. We propose a theoretical explanation of DP and DR based on interoceptive predictive coding, and discuss how transient experiences of DP and DR may be induced in the non-clinical (...) population using virtual reality. Further, we review the use of heartbeat evoked potentials in detecting the neural correlates of DP and DR allowing for an objective measure of these experiences in the non-clinical population. Finally, we discuss how the induction and detection of transient experiences of DP and DR in the non-clinical population could shed light on how the brain constructs one’s sense of self and reality.

The body-oriented approach in the philosophy of cognitive sciences is gaining in importance in the conditions of the formation of new high-tech contexts. The problem of interoception and integration of bodily data into socio-economic processes requires a comprehensive analysis and ethical assessment. This article examines the conceptual foundations of the body-oriented approach and its impact on the essence of cognitive processes. The main advantages and disadvantages of this approach are presented. We consider the methodological conflict zones of the bodily paradigm (...) and traditional methodological attitudes of the cognitive sciences. The system ofinteroceptive sensations is a special «layer» of bodily experience. The social functions of interoceptive sensations are an interdisciplinary research area that focuses on the mechanisms of interaction between the private content of bodily experience and systems of social interaction. The regularity between interoceptive sensations and human behavioral patterns reflects the importance of examining bodily data. Today, the market for bodily data is just beginning to form, but at the same time it is already playing an important role in global digital transformation processes. A multitude of applications and wearable digital devices that track bodily activity and generate gigantic amounts of data are used today by millions of people around the world. The identification of bodily activity leads to the emergence of new forms of interaction between a person and socio-institutional systems, the specific properties of which are also considered in this article.

In my general aim to probe a non-reductionist Philosophy of Cognitive Enhancement, considering social self-other relations and the epistemic 2PP in social syn-aesthetic tuning-ins, synchronisations and tuning-outs, this paper amplifies the Aristotelian common sense concept κοινὴ αἲσθησις2 by analysing the concept and metaphor of “resonance”3 in contemporary debates on >resonance< as acoustic and multimodal figure of thought. Resonance as shown in scientific models derived from acoustics will be applied to an aesthetic comunity of sensing and making music together as explored (...) in Alfred Schütz, as well as in social relations in social psychology. Finally, this paper puts resonance to test as well in technical atunements of social relations and closes with the necessary resistance to imposition of social resonance, introduced in this paper as xenoresonance.

Using multimodal conversation analysis, we investigate how novices learning the “inner body” acting technique in the context of a community theater project share their experiences of the bodily exercises through verbal and embodied conduct. We focus on how verbal description and bodily enactment of the experience mutually elaborate each other, and how the experienced sensorimotor and affective qualities are made to be witnessed and recognized by the others. Participants describe their experiences without naming qualities. Instead, a display of the experienced (...) qualities is made accessible to others through coordinating the unfolding talk and bodily conduct. In particular, we show how grammatical and action projection is fulfilled by interconnected verbal and embodied conduct, with body movement and posture giving off ineffable experiential qualities. The moving body appears both as a source of the experience and as a resource for depicting perceived qualities to others; additional resources (non-specific person reference and gaze aversion) contribute to organizing the subjective and intersubjective layers of the reflection of the experiences. The study contributes to and extends recent research on sensoriality in interaction by focusing on phenomena of proprioception and interoception. The data are two cases drawn from 60 h of video-recordings made in the context of a devised community theater project. The data are in Finnish with English translations. (shrink)

Interoception in the broader sense refers to the perception of internal states, including the perception of the actual state of the internal organs and the motor system. Dimensions of interoception include interoceptive accuracy, i.e., the ability to sense internal changes assessed with behavioral tests, confidence rating with respect to perceived performance in an actual behavioral test, and interoceptive sensibility, i.e., the self-reported generalized ability to perceive body changes. The relationship between dimension of cardioceptive and proprioceptive modalities and their association with (...) affect are scarcely studied. In the present study, undergraduate students filled out questionnaires assessing positive and negative affect, interoceptive sensibility, and body competence. Following this, they completed a behavioral task assessing cardioceptive accuracy and two tasks assessing proprioceptive accuracy with respect to the tension of arm flexor muscles and the angular position of the elbow joint. Confidence ratings were measured with visual analog scales after the tasks. With the exception of a weak association between cardioceptive accuracy and the respective confidence rating, no associations between and within modalities were found with respect to various dimensions of interoception. Further, the interoceptive dimensions were not associated with state and trait positive and negative affect and perceived body competence. In summary, interoceptive accuracy scores do not substantially contribute to conscious representations of cardioceptive and proprioceptive ability. Within our data, non-pathological affective states are not associated with the major dimensions of interoception for the cardiac and proprioceptive modalities. (shrink)

Scholars and providers are coming to realize that one’s ability to notice and respond to internal body sensations contributes to an overall sense of wellbeing. Research has demonstrated a relationship between interoceptive awareness and anxiety, for example. Currently, however, tools for evaluating one’s interoception lack the conceptual foundation and clarity necessary to identify everyday behaviors that specifically reflect interoceptive awareness. Unlike existing interoceptive measures, the Sensory Profile Interoception scale is participation-based and grounded in Dunn’s Sensory Processing framework. In this study (...) we investigated concurrent validity by correlating the SPI with the Adolescent/Adult Sensory Profile ; we investigated construct validity by correlating the SPI with the Perth Alexithymia Scale, the Body Awareness Scale, and the State-Trait Anxiety Inventory. Using the REDCAP online platform, 74 college-aged participants completed the measures. Using Spearman rank order correlations there were statistically significant relationships between the corresponding sensory pattern subscales on SPI and A/ASP. The PAS was only weakly related to the registration subscale of the SPI. The BAS had significant relationships with seeking and avoiding on the SPI. The STAI had significant relationships with sensitivity and registrations of the SPI. Taken together, these findings provide evidence of construct validity of the SPI to identify participation patterns associated with both high and low interoception. With the more precise information the SPI provides, professionals can design tailored interventions to support everyday life goals and researchers can study interoception within authentic activities.

Background:Stress can frequently occur in the driving context. Its cognitive effects can be deleterious and lead to uncomfortable or risky situations. While stress detection in this context is well developed, regulation using dedicated advanced driver-assistance systems (ADAS) is still emergent.Objectives:This systematic review focuses on stress regulation strategies that can be qualified as “subtle” or “mindless”: the technology employed to perform regulation does not interfere with an ongoing task. The review goal is 2-fold: establishing the state of the art on such (...) technological implementation in the driving context and identifying complementary technologies relying on subtle regulation that could be applied in driving.Methods:A systematic review was conducted using search operators previously identified through a concept analysis. The patents and scientific studies selected provide an overview of actual and potential mindless technology implementations. These are then analyzed from a scientific perspective. A classification of results was performed according to the different stages of emotion regulation proposed by the Gross model.Results:A total of 47 publications were retrieved, including 21 patents and 26 studies. Six of the studies investigated mindless stress regulation in the driving context. Patents implemented strategies mostly linked to attentional deployment, while studies tended to investigate response modulation strategies.Conclusions:This review allowed us to identify several ADAS relying on mindless computing technologies to reduce stress and better understand the underlying mechanisms allowing stress reduction. Further studies are necessary to better grasp the effect of mindless technologies on driving safety. However, we have established the feasibility of their implementation as ADAS and proposed directions for future research in this field. (shrink)
