Does the body talk to the body? The relationship between different body representations while observing others’ body parts

The way human bodies are represented is central in everyday activities. The cognitive system must combine internal, visceral, and somatosensory, signals to external, visually driven information generated from the spatial placement of others’ bodies and the own body in the space. However, how different body representations covertly interact among them when observing human body parts is still unclear. Therefore, we investigated the implicit processing of body parts by manipulating either the body part stimuli’ posture (conditions a and b) or the participants’ response body posture (conditions c, d, and e) in healthy participants (N = 70) using a spatial compatibility task called Sidedness task. The task requires participants to judge the colour of a circle superimposed on a task-irrelevant body part picture. Responses are facilitated when the spatial side of the responding hand corresponds to the spatial code generated by the hand stimulus's position with respect to a body of reference. Results showed that the observation of the task-irrelevant body parts oriented participants’ attention and facilitated responses that were spatial compatible with the spatial position such body parts have within a configural representation of the body structure (i.e., Body Structural Representation) in all the five experimental conditions. Notably, the body part stimuli were mentally attached to the body according to the most comfortable and less awkward postures, following the anatomo-physiological constraints. Moreover, the pattern of the results was not influenced by manipulating the participants’ response postures, suggesting that the automatic and implicit coding of the body part stimuli does not rely on proprioceptive information about one's body (i.e., Body Schema). We propose that the human body's morphometry knowledge is enriched by biomechanical and anatomo-physiological information about the real body movement possibilities. Moreover, we discuss the importance of the automatic orienting of attention based on the sidedness within the context of imitational learning.     

The form of the soul ― on the body in Freud’s psychoanalysis

To formulate the problem of the relation between body and soul in terms of how one should understand the relation between consciousness and the brain, or in terms of explaining how mind can arise out of matter, is a modern and far from innocent tendency that has instigated the whole spectrum of theories and answers suggested by the philosophy of mind of the so-called Analytic tradition during the 20th century. During the last 5 decades, we have seen a number of attempts at incorporating Freud into this discussion about the relation between body and soul. In this article, the author develops an argument according to which the philosophy of mind of the Analytic tradition is not really an appropriate intellectual environment for Freud´s theory of the body and its constitutive rôle. Rather, we should turn to phenomenology and transcendental philosophy where the body is thematized, not in terms of matter taken to give rise to consciousness in an empirical sense, but rather in terms of the “lived body” that is taken, in a transcendental sense, to constitute the organization of meaning in our conscious and our unconscious psychological life. On the basis of an outline of this phenomenological theory, the author argues that Freud, most of all in his theory of psychosexual development, thematizes the body as the form of the soul.     

“All things are already complete in my body”: An explanation of the views of the Taizhou School on the human body

By means of a theoretical analysis from the point of view of phenomenology of the body, this essay tries to explain the views of Taizhou School on the body so as to apprehend the essence of Confucian thought, which is a philosophy that seeks to “establish oneself” and “cultivate oneself” rather than a “philosophy of consciousness.”     

Lost in the move? Secondary task performance impairs tactile change detection on the body

Change blindness, the surprising inability of people to detect significant changes between consecutively-presented visual displays, has recently been shown to affect tactile perception as well. Visual change blindness has been observed during saccades and eye blinks, conditions under which people’s awareness of visual information is temporarily suppressed. In the present study, we demonstrate change blindness for suprathreshold tactile stimuli resulting from the execution of a secondary task requiring bodily movement. In Experiment 1, the ability of participants to detect changes between two sequentially-presented vibrotactile patterns delivered on their arms and legs was compared while they performed a secondary task consisting of either the execution of a movement with the right arm toward a visual target or the verbal identification of the target side. The results demonstrated that a motor response gave rise to the largest drop in perceptual sensitivity (as measured by changes in d′) in detecting changes to the tactile display. In Experiment 2, we replicated these results under conditions in which the participants had to detect tactile changes while turning a steering wheel instead. These findings are discussed in terms of the role played by bodily movements, sensory suppression, and higher order information processing in modulating people’s awareness of tactile information across the body surface.     

Does your body count? Embodied influences on the preferred counting direction of preschoolers

Many studies confirm that preschoolers from left-to-right reading societies count from left to right, which reflects the cultural direction of their spatial-numerical associations (SNAs). Other factors, not directly related to cultural experience, have not yet been systematically examined as potential determinants of counting direction in preschool children. In this study, we test one such determinant, i.e. whether and how counting direction is related to body-centred reference frames, such as a preferred hand in different spatial-motoric settings. We first asked preschoolers to count spontaneously. Then, we asked them to use a particular hand to count objects presented close to or far away from their bodies. An overall left-to-right counting dominance was replicated, but it was modulated by a counting hand in both tasks: Children preferred to start counting from an object ipsilateral to the hand used. This pattern increased when stimuli were in a position close to the body. We conclude that early counting preferences of preliterate children are embodied. The SNAs which were assessed are not only related to culture but also to situated individual bodily reference frames.     

Parapsychology and the mind‐body problem

The paper argues that there are effectively only two tenable theories of the mind‐brain relationship: ‘epiphenomenalism’ and ‘radical dualism’ (interactionism). So long as account is taken only of the conventional sciences, the odds are heavily stacked in favour of epiphenomenalism. However, once the findings of parapsychology are admitted to consideration, a very different situation obtains. It is here argued that parapsychology only makes sense within a dualist metaphysic.     

Attentional biases using the body in the crowd task: are angry body postures detected more rapidly?

Research using schematic faces has consistently demonstrated attentional biases towards threatening information (angry faces), which are accentuated for individuals with higher levels of anxiety. However, research has yet to reveal whether this is the case for other nonverbal channels of communication. In the research reported here, ninety-five undergraduates completed a body in the crowd task analogous to the face in the crowd task, to examine whether attentional biases for threat existed for schematic body postures. Participants demonstrated faster detection of threat. A discrepant angry posture in a neutral crowd was identified quicker than a discrepant happy posture in a neutral crowd. This effect was pronounced for individuals with higher self-reported levels of trait anxiety. Results also demonstrated evidence of delayed disengagement from threat. Individuals were slower (i.e., more distracted) by identical crowds of angry postures rather than happy or neutral crowds and were slower to detect a discrepant neutral posture among an angry crowd than neutral among a happy crowd. These findings are the first to establish threat biases using body postures in a visual search paradigm. The results are in accordance with previous research using schematic face stimuli. Theoretical and practical implications are discussed.

Does this book make me look fat? The effect of protagonist body weight and body esteem on female readers’ body esteem

Effects of visual representations of the thin ideal in the media have been widely explored, but textual representations of the thin ideal in novels have received scant attention. The chick literature genre has been criticized for depicting characters who worry about their body weight and who have poor body esteem. Excerpts from two chick lit novels were used to examine the effect of a protagonist's body weight and body esteem on college women's (N = 159) perceptions of their sexual attractiveness and weight concern. Two narratives were used to minimize the possibility that idiosyncratic characteristics of one excerpt might influence the study's results. Underweight (vs. healthy weight) protagonists predicted readers’ lower perceived sexual attractiveness. Protagonists with low body esteem (vs. control) predicted readers’ increased weight concern. Scholars and health officials should be concerned about the effect chick lit novels might have on women's body image.     

Is the body represented in everyday bodily activities?

There seem to be good reasons to think that there must be body representations or some kind of body content required for riding a bike or grabbing a cup of coffee. However, when I ride a bike or grab a cup of coffee, am I just representing the bike and the cup? Or am I actually also representing my body and bodily movements? The thesis of this paper is that the body not only figures in the content that guides everyday activities but that it must. How is this possible? Exactly what elements of the subject’s body can be said to figure in this content? I will proceed in three steps: in the first, I bring together the conceptual resources that seem to be required; in the second, I discuss a couple of proposals about how to link the notion of affordance and the topic of bodily representations, arguing that they are misguided; finally, I propose a view according to which the body’s physical and spatial properties are an unavoidable part of the content that guides everyday activities.     

Effects of gait speed on the body’s center of mass motion relative to the center of pressure during over-ground walking

Preferred walking speed (PWS) reflects the integrated performance of the relevant physiological sub-systems, including energy expenditure. It remains unclear whether the PWS during over-ground walking is chosen to optimize one’s balance control because studies on the effects of speed on the body’s balance control have been limited. The current study aimed to bridge the gap by quantifying the effects of the walking speed on the body’s center of mass (COM) motion relative to the center of pressure (COP) in terms of the changes and directness of the COM-COP inclination angle (IA) and its rate of change (RCIA). Data of the COM and COP were measured from fifteen young healthy males at three walking speeds including PWS using a motion capture system. The values of IAs and RCIAs at key gait events and their average values over gait phases were compared between speeds using one-way repeated measures ANOVA. With increasing walking speed, most of the IA and RCIA related variables were significantly increased (p < 0.05) but not for those of the frontal IA. Significant quadratic trends (p < 0.05) with highest directness at PWS were found in IA during single-limb support, and in RCIA during single-limb and double-limb support. The results suggest that walking at PWS corresponded to the COM-COP control maximizing the directness of the RCIAs over the gait cycle, a compromise between the effects of walking speed and the speed of weight transfer. The data of IA and RCIA at PWS may be used in future assessment of balance control ability in people with different levels of balance impairments.     

Touchant-touché: the role of self-touch in the representation of body structure

The "body image" is a putative mental representation of one's own body, including structural and geometric details, as well as the more familiar visual and affective aspects. Very little research has investigated how we learn the structure of our own body, with most researchers emphasising the canonical visual representation of the body when we look at ourselves in a mirror. Here, we used non-visual self-touch in healthy participants to investigate the possibility that primary sensorimotor experience may influence cognitive representations of one's own body structure. Participants used the fingers of one hand (the 'active' hand), to touch the fingers of the other (the 'passive' hand). A conflict between the experience of the active and passive hand was introduced by experimenter interleaving their fingers with the fingers of the participant's passive hand. This led to the active hand experiencing that it touched more fingers than the passive hand felt it was being touched by. The effects on representation of body structure were assessed using an implicit measure based on Kinsbourne and Warrington's 'in-between task'. We found an underestimation of the number of fingers in the central part of the hand specifically linked to the experience of self-touch. This pattern of results corresponds to the experience of the passive hand, but not the active hand. Nevertheless, comparable reorganisation of fingers within the hand representation was found for both active and passive hands. We show that primary sensorimotor experience can modify the representation of body structure. This modification is driven by the passive experience of being touched, rather than by the active experience of touching. We believe this is the first experimental study of effects of self-touch on the mental representation of the body.     

Written on the body? Individual differences between British adults who do and do not obtain a first tattoo

Swami, V. (2012). Written on the body? Individual differences between British adults who do and do not obtain a first tattoo. Scandinavian Journal of Psychology 53, 407–412. This study compared individual psychological differences of individuals who do and not obtain their first tattoo. A total of 136 British residents visiting a tattoo parlour completed measures of the Big Five personality factors, Sensation Seeking, Need for Uniqueness, distinctive appearance investment, attitudes to authority, and sociosexual orientation. As compared to individuals who did not subsequently obtain a tattoo, individuals that did were significantly less conscientious, more extraverted, more willing to engage in sexual relations in the absence of commitment, and had higher scores on sensation seeking, Need for Uniqueness, and distinctive appearance investment. The effect sizes of uncovered differences were small‐to‐moderate (η_p² = .07–.14). These results are discussed in relation to the mainstreaming of tattoos in contemporary, post‐industrialised societies.     

Mirror, mirror on the wall, who is the ugliest of them all? The psychopathology of mirror gazing in body dysmorphic disorder

Patients with Body Dysmorphic Disorder (BDD) may spend many hours in front of a mirror but little is known about the psychopathology or the factors that maintain the behaviour. A self-report mirror gazing questionnaire was used to elicit beliefs and behaviours in front of a mirror. Two groups were compared, which consisted of 55 controls and 52 BDD patients. Results: Prior to gazing, BDD patients are driven by the hope that they will look different; the desire to know exactly how they look; a belief that they will feel worse if they resist gazing and the desire to camouflage themselves. They were more likely to focus their attention on an internal impression or feeling (rather than their external reflection in the mirror) and on specific parts of their appearance. They were also more likely to practise showing the best face to pull in public or to use “mental cosmetic surgery” to change their body image than controls. BDD patients invariably felt worse after mirror gazing and were more likely to use ambiguous surfaces such as the backs of CDs or cutlery for a reflection. Conclusion: Mirror gazing in BDD consists of a series of complex safety behaviours. It does not follow a simple model of anxiety reduction that occurs in the compulsive checking of obsessive–compulsive disorder. The implications for treatment are discussed.     

The impact of thin idealized media images on body satisfaction: Does body appreciation protect women from negative effects?

This article examines whether positive body image can protect women from negative media exposure effects. University women (N = 112) were randomly allocated to view advertisements featuring ultra-thin models or control images. Women who reported high levels of body appreciation did not report negative media exposure effects. Furthermore, the protective role of body appreciation was also evident among women known to be vulnerable to media exposure. Women high on thin-ideal internalization and low on body appreciation reported appearance-discrepancies that were more salient and larger when they viewed models compared to the control group. However, women high on thin-ideal internalization and also high on body appreciation rated appearance-discrepancies as less important and no difference in size than the control group. The results support the notion that positive body image protects women from negative environmental appearance messages and suggests that promoting positive body image may be an effective intervention strategy.
