The embodied self: Making a fist enhances men’s power-related self-conceptions

The effect of physical cleansing on moral activities

Research suggests that physical cleansing leads individuals to perceive themselves as morally purer, thereby influencing their moral activities, but findings are inconsistent. Some researchers have found that individuals act more morally after physical cleansing, whereas others have observed the reverse effect. Building on embodied cognition theory, which holds that cognition is developed from physical experience and that this experience in turn guides their responses, we hypothesized that physical cleansing would have a general impact on individuals' moral activities by highlighting themselves. In contrast to previous research, we did not expect that physical cleansing would directly make people more (im)moral. Two experiments were conducted to test our hypotheses. In experiment 1, participants who had bathed showed reduced susceptibility to external moral priming (morality-related descriptions of themselves) than did control participants. Experiment 2 showed that physical cleansing (but not the control condition) amplified the interplay among participants' moral activities, depending on the order of immoral behavior and intention measurement. Taken together, these results suggest that physical cleansing strengthens the connection between individuals' morality and bodily experiences, weakening the effect of external priming (experiment 1) and enhancing the influence of moral activities performed by themselves (experiment 2). Although further research is required to provide direct evidence for these findings, our study contributes to the integration of inconsistencies in previous findings by suggesting a new perspective for the understanding of the embodied effect of physical cleansing.

Meditation and interoception: a conceptual framework for the narrative and experiential self

The concept of the self is complex and there is no consensus on what the self is. However, there are emerging patterns in the literature that point to two different selves, the narrative and experiential self. The narrative self refers to a conceptual or representational knowledge of the self that extends across time and manifests in self-reflection and personality assessments. The experiential self refers to first-person perception, moment-to-moment awareness, embodiment, and a sense of agency. These two selves are reliably linked to two distinct neural circuits, the default mode network (DMN) and the insula and salience network (SN). One of the consistent themes in the meditative and mindfulness literature is a change in the perspective of the self. In this paper, I will review how meditation alters those neural circuits providing a plausible mechanism that can explain the changes in the self. I also propose a rudimentary conceptual framework to account for some of the mixed results found throughout meditation literature.

Establishing conversational engagement and being effective: The role of body movement in mediated communication

A model for investigating the effects of body movement on conversational effectiveness in computer-mediated communication (CMC) is developed based on theories of motor cognition and embodiment. Movement is relevant to a wide range of CMC settings, including remote interviews, court testimonials, instructing, medical consultation, and socializing. The present work allows for a consideration of different forms of motoric activation, including gesturing and full-body motion, in mediated conversational settings and the derivation of a range of testable hypothesis. Motor cognition and embodiment provide an account of how speaker and listener become subject to the consequences of the muscular activation patterns that come with body movement. While movement supports internal elaboration, thus helping the speaker in formulating messages, it also has direct effects on the listener through behavioral synchrony and motor contagion. The effects of movement in CMC environments depend on two general characteristics: the level of visibility of movement and the extent to which the technology facilitates or inhibits movement. Available channels, set-up of technology, and further customization therefore determine whether movement can fulfil its internal functions (relevant to cognitive-affective elaboration of what is being said by the speaker) and its external functions (relevant to what is being perceived by and activated within the listener). Several indicators of conversational effectiveness are identified that serve as outcome variables. This MCEE model is intended to help users, developers and service provides to make CMC more engaging and more meaningful.

The inside of me: interoceptive constraints on the concept of self in neuroscience and clinical psychology

Humans are unique in their ability to think about themselves and carry a more or less clear notion of who they are in their mind. Here we review recent evidence suggesting that the birth, maintenance, and loss of the abstract concept of 'self' is deeply tied to interoception, the sense of internal physiological signals. Interoception influences multiple facets of the self-concept, cutting across its material, social, moral, and agentive components. Overall, we argue that interoception contributes to the stability of the self-concept over time, unifying its layers and constraining the degree to which it is susceptible to external influences. Hence, the core features of the self-concept are those that correlate more with inner bodily states. We discuss the implications that this may have for theories of embodied cognition as well as for the understanding of psychiatric disorders in which the concept of self appears fragmented or loose. Finally, we formulate some empirical predictions that could be tested in future studies to shed further light on this emerging field.

Embodied power: Specific facial muscles automatically respond to power-related information processing

Derived from embodiment approaches, we tested the assumption that specific facial muscle contractions are simulated upon the categorization of power-related words. For this, we used an interference task that required participants to categorize trait adjectives according to their underlying power. Response latencies of contractions of either the corrugator supercilii (pulls the eyebrows together) or the depressor anguli oris muscle (pulls the corners of the mouth downwards) were assessed. In two experiments, we expected and found that the speed of facial responses crucially depends on whether a high power or low power adjective was categorized. More precisely, corrugator responses were faster to high power adjectives whereas depressor responses were faster to low power adjectives. These findings support the assumption that the meaning of power is at least partially grounded in motor representations underlying specific facial expressions.

Swearing and coprophenomena - A multidimensional approach

Swearing, cursing, expletives - all these terms are used to describe the utterance of taboo words. Studies show that swearing makes up around 0.5 % of the daily spoken content, however, the inter-individual variability is very high. One kind of pathologic swearing is coprolalia in Tourette syndrome (TS), which describes the involuntary outburst of taboo words. Coprolalia occurs in approximately 20-30 % of all patients with TS. This review compares swearing in healthy people and coprolalia in people with TS and is the first one to develop a multidimensional framework to account for both phenomena from a similar perspective. Different research findings are embedded in one theoretical framework consisting of reasons, targets, functions/effects and influencing factors for swearing and coprolalia. Furthermore, the very limited research investigating obscene gestures and copropraxia, compulsive obscene gestures, is summarized. New research questions and gaps are brought up for swearing, obscene gestures and coprophenomena.

Expansive and Contractive Postures and Movement: A Systematic Review and Meta-Analysis of the Effect of Motor Displays on Affective and Behavioral Responses

This review and meta-analysis explores the experimental effects of expansive and contractive motor displays on affective, hormonal, and behavioral responses. Experimental studies were located through systematic literature searches. Studies had to manipulate motor displays to either expansive or contractive displays and investigate the effect of the displays on affect, hormones, or overt behavior. Meta-analyses were conducted to determine the pooled, standardized mean differences between the effects of motor displays on affective, hormonal, and behavioral responses. From 5,819 unique records, 73 relevant studies were identified. Robust differences between expansive and contractive displays emerged for affective responses and overt behavioral responses across contexts, type of manipulation, and methods of measurement. The results suggest that the effects are driven by the absence of contractive motor displays (contractive vs. neutral displays: Hedges's g = 0.45) rather than the presence of expansive displays (expansive vs. neutral displays: g = 0.06). The findings stand as a corrective to previous research, as they indicate that it is the absence of contractive displays rather than the presence of expansive displays that alters affective and behavioral responding. Future research should include neutral control groups, use different methods to assess hormonal change, and investigate these effects in the context of ideographic goals.

Try-on experience with augmented reality comforts your decision

Purpose

The purpose of this paper is to understand how augmented reality (AR) try-on experiences facilitate consumers’ shopping decision. Focusing on the immersion and psychological ownership, the study investigated how the properties of AR experiences (environmental embedding (EE) and simulated physical control (SPC)) affect decision comfort.

Design/methodology/approach

This research theoretically and empirically analyzes how each property of AR experiences affects consequential psychological states and then further increases decision comfort by employing an existing AR try-on mobile application. A total of 99 valid responses were used for the partial least square structural equation modeling analysis. One’s prior AR try-on experience was predicted as a moderator and analyzed using SPSS-based PROCESS macro.

Findings

The results demonstrated that EE and SPC evoke immersion and the feeling of ownership of a virtual product, which increased decision comfort. The moderating effect of one’s prior AR try-on experience showed that the impact of EE and SPC on immersion was attenuated for those with prior experience. Further, immersion mediated the effect of EE but SPC on the feeling of ownership, which corroborated the direct effect of SPC on the feeling of ownership.

Practical implications

Firms must consider technological and user-experience features that can induce users to perceive high levels of AR characteristics such as EE and SPC. Practitioners should develop realistic content that can correctly place virtual products on users to enhance EE. Including more interactive features is encouraged to provide users with a feeling of control toward the virtual product that directly leads to ownership and positively affects decision making. Further, practitioners need to be cautious about consumers getting used to the new technology; retailers and marketers need to focus on creating new and innovative content to continually engage customers.

Originality/value

This study adopted EE and SPC to determine how each property of AR experience forms the consequential psychological states, particularly depending on one’s prior experience. Methodologically, the study provided external validity in conducting an experiment by adopting an existing AR mobile application available in the market and employing an objective measure of respondents (e.g. prior AR try-on experience).

Taboo gesticulations as a response to pain

Background and aims

Prior research indicates that swearing increases pain tolerance and decreases pain perception in a cold pressor task. In two experiments, we extend this research by testing whether taboo hand gesticulations have a similar effect.

Methods

Study 1 focused on males and females who, across two trials, submerged an extended middle finger (taboo) and an extended index finger (control) in ice water until discomfort necessitated removal. Study 2 focused exclusively on pain perception in males who, across three trials, submerged their hand, flat, with extended middle finger and with extended index finger, for 45 s each.

Results

In study 1 taboo gesticulation did not increase pain tolerance or reduce pain perception compared with the index finger control condition, as a main effect or as part of an interaction with condition order. While there was a gesture×gender interaction for pain tolerance, this was driven by an increased pain tolerance for the index finger gesture for women but not men. The results of study 2 again showed that taboo gesticulation did not lower pain perception, although it did increase positive affect compared with both non-taboo gesture conditions.

Conclusions

Taken together these results provide only limited evidence that taboo gesticulation alters the experience of pain. These largely null findings further our understanding of swearing as a response to pain, suggesting that the activation of taboo schemas is not sufficient for hypoalgesia to occur.

Bodily-Contact Communication Medium Induces Relaxed Mode of Brain Activity While Increasing Its Dynamical Complexity: A Pilot Study

We present the results of the analysis of the effect of a bodily-contact communication medium on the brain activity of the individuals during verbal communication. Our results suggest that the communicated content that is mediated through such a device induces a significant effect on electroencephalogram (EEG) time series of human subjects. Precisely, we find a significant reduction of overall power of the EEG signals of the individuals. This observation that is supported by the analysis of the permutation entropy (PE) of the EEG time series of brain activity of the participants suggests the positive effect of such a medium on the stress relief and the induced sense of relaxation. Additionally, multiscale entropy (MSE) analysis of our data implies that such a medium increases the level of complexity that is exhibited by EEG time series of our participants, thereby suggesting their sustained sense of involvement in their course of communication. These findings that are in accord with the results reported by cognitive neuroscience research suggests that the use of such a medium can be beneficial as a complementary step in treatment of developmental disorders, attentiveness of schoolchildren and early child development, as well as scenarios where intimate physical interaction over distance is desirable (e.g., distance-parenting).

Sex-specific effects of posture on the attribution of handedness to an imagined agent

In a series of previous studies, we found that when participants were required to imagine another person performing a manual action, they imagined a significantly higher proportion of actions performed with their dominant rather than non-dominant hand, which indicates that shared motor representations between the self and the other are involved also during the imagination of others' actions. Interestingly, the activation of lateralized body-specific motor representations (as indexed by the congruence between the participant's handedness and the imagined person's handedness) appeared to be affected by the visual perspective adopted and participants' handedness. Given that past literature indicates that incongruent or unnatural postures interfere with motor imagery, we tested 480 right-handed participants to investigate whether subjects holding their right hand behind their back would have imagined right-handed actions less frequently than those holding their left hand behind their back. Moreover, we examined the effects of participant's sex, action category (simple or complex) and hand shape (open or fist). Contrary to our prediction, female participants holding their right hand behind their back imagined right-handed actions more frequently than those holding their left hand behind their back, whereas no significant effect was observed in male participants. We propose that the muscle contraction needed to keep a hand behind the back could activate the motor representations of that hand so as to increase the likelihood of imagining an action performed with the corresponding hand. Moreover, the sex difference observed is consistent with the greater use of embodied strategies by females than by males.

Conscientiousness and Extraversion relate to responsiveness to tempo in dance

Previous research has shown broad relationships between personality and dance, but the relationship between personality and specific structural features of music has not been explored. The current study explores the influence of personality and trait empathy on dancers' responsiveness to small tempo differences between otherwise musically identical stimuli, measured by difference in the amount in acceleration of key joints. Thirty participants were recorded using motion capture while dancing to excerpts from six popular songs that were time-stretched to be slightly faster or slower than their original tempi. Analysis revealed that higher conscientiousness and lower extraversion both correlated with greater responsiveness to tempo change. Partial correlation analysis revealed that conscientiousness remained significantly correlated with responsiveness when extraversion was controlled, but not vice versa. No effect of empathy was found. Implications are discussed.

Dressing up posture: The interactive effects of posture and clothing on competency judgements

Individuals often receive judgements from others based on their clothing and their posture. While both of these factors have been found to influence judgements of competency independently, their relative importance in impression formation is yet to be investigated. We address this by examining interactive effects of posture and clothing on four competency measures: confidence, professionalism, approachability, and likeliness of a high salary. Participants rated photographs of both male and female models pictured in different postures (strong, neutral, weak) in smart clothing (a suit for males; both a trouser suit and skirt suit for females) and casual clothing. We confirm that posture manipulations affected judgements of individuals differently according to the clothing they were pictured in. The nature of these interactions varied by gender and, for women, competency judgements differed according to attire type (trouser or skirt suit). The implications of these findings in relation to impression formation are discussed.

In vitro strain in human metacarpal bones during striking: testing the pugilism hypothesis of hominin hand evolution

The hands of hominins (i.e. bipedal apes) are distinguished by skeletal proportions that are known to enhance manual dexterity but also allow the formation of a clenched fist. Because male–male physical competition is important in the mating systems of most species of great apes, including humans, we tested the hypothesis that a clenched fist protects the metacarpal bones from injury by reducing the level of strain during striking. We used cadaver arms to measure in vitro strain in metacarpals during forward strikes with buttressed and unbuttressed fist postures and during side slaps with an open palm. If the protective buttressing hypothesis is correct, the clenched fist posture should substantially reduce strain in the metacarpal bones during striking and therefore reduce the risk of fracture. Recorded strains were significantly higher in strikes in which the hand was secured in unbuttressed and slapping postures than in the fully buttressed posture. Our results suggest that humans can safely strike with 55% more force with a fully buttressed fist than with an unbuttressed fist and with twofold more force with a buttressed fist than with an open-hand slap. Thus, the evolutionary significance of the proportions of the hominin hand may be that these are the proportions that improved manual dexterity while at the same time making it possible for the hand to be used as a club during fighting.

Look Up for Healing: Embodiment of the Heal Concept in Looking Upward

OBJECTIVE

Conceptual processing may not be restricted to the mind. The heal concept has been metaphorically associated with an "up" bodily posture. Perceptual Symbol Systems (PSS) theory suggests that this association is underpinned by bodily states which occur during learning and become instantiated as the concept. Thus the aim of this study was to examine whether processing related to the heal concept is promoted by priming the bodily state of looking upwards.

METHOD

We used a mixed 2x2 priming paradigm in which 58 participants were asked to evaluate words as either related to the heal concept or not after being primed to trigger the concept of looking up versus down (Direction--within subjects). A possible dose-response effect of priming was investigated via allocating participants to two 'strengths' of prime, observing an image of someone whose gaze was upward/downward (low strength) and observing an image of someone whose gaze was upward/downward while physically tilting their head upwards or downwards in accord with the image (high strength) (Strength--between subjects).

RESULTS

Participants responded to words related to heal faster than words unrelated to heal across both "Strength" conditions. There was no evidence that priming was stronger in the high strength condition.

CONCLUSION

The present study found that, consistent with a PSS view of cognition, the heal concept is embodied in looking upward, which has important implications for cognition, general health, health psychology, health promotion and therapy.

Mapping the brain's metaphor circuitry: metaphorical thought in everyday reason

An overview of the basics of metaphorical thought and language from the perspective of Neurocognition, the integrated interdisciplinary study of how conceptual thought and language work in the brain. The paper outlines a theory of metaphor circuitry and discusses how everyday reason makes use of embodied metaphor circuitry.

The Spatial Power Motivation Scale: a semi-implicit measure of situational power motivation

We introduce a new nonverbal and unobtrusive measure to assess power motive activation, the Spatial Power Motivation Scale (SPMS). The unique features of this instrument are that it is (a) very simple and economical, (b) reliable and valid, and (c) sensitive to situational changes. Study 1 demonstrates the instrument's convergent and discriminant validity with explicit measures. Study 2 demonstrates the instrument's responsiveness to situational power motive salience: anticipating and winning competition versus losing competition and watching television. Studies 3 and 4 demonstrate that thoughts of competition result in higher power motivation specifically for individuals with a high dispositional power motive.

From the heart: hand over heart as an embodiment of honesty

Motor movements increase the accessibility of the thought content and processes with which they typically co-occur. In two studies, we demonstrate that putting a hand on one’s heart is associated with honesty, both perceived in others and shown in one’s own behavior. Target persons photographed when performing this gesture appeared more trustworthy than the same targets photographed with both hands down (Study 1). Participants who put their hand on their hearts were more willing to admit their lack of knowledge (Study 2), compared to when they performed a neutral gesture. These findings replicate and extend the notion that bodily experience related to abstract concepts of honesty can influence both perceptions of others, and one’s own actions.

She Stoops to Conquer? How Posture Interacts With Self-Objectification and Status to Impact Women’s Affect and Performance

Research suggests that posture exerts powerful affective and cognitive influences, although recent studies have indicated that these embodiment effects are moderated by gender. We examined two sociocultural factors that may contribute to the effects of postural feedback in women: self-objectification and power. Across a 2 × 2 × 2 between-subjects design, 80 female undergraduates completed various cognitive tasks and self-report measures after having been in an upright or slouched posture, seated in either a (powerful) throne or child’s chair, and wearing either a formfitting (objectifying) tank top or loose sweatshirt. The results showed that posture had the predicted influence on mood, with those seated upright reporting more positive mood than those seated in a slouched position. For the cognitive tasks, our findings were more complex and, due to low power, are best considered preliminary. Participants who were seated upright in a child’s chair while wearing a sweatshirt attempted the highest number of math items compared to those in the other conditions, supporting our prediction that postural benefits would be greatest in a context where power cues were gender-appropriate and self-objectification effects were attenuated. On a measure of satisfaction with performance, our findings suggest that self-objectification outweighed the power manipulation, leading to poorer outcomes when a seated position emphasized sexualized features of the body. Taken together, our results suggest that embodiment effects appear to be impacted by contextual cues, perhaps particularly for women.

Sun-induced frowning fosters aggressive feelings

We tested whether aggressiveness can be triggered by the involuntary frowning that occurs when people face the sun, due to the fact that sun-induced frowning involves the same pattern of facial muscle activation as in the expression of anger (interestingly, Charles Darwin remarked on the sunshade-like nature of frowning). In line with data showing that experimentally and unobtrusively induced facial and body displays facilitate congruent feelings, we found that participants walking against the sun without sunglasses scored higher in a self-report measure of anger and aggression compared to those walking with the sun behind and/or wearing sunglasses. We also suggest that frowning at the sun affects mood very quickly, because we did not find any effect of walking time on self-reported aggressiveness. Our results provide the first evidence of the ecological validity of the facial feedback hypothesis.

Affective judgement about information relating to competence and warmth: an embodied perspective

Several studies have shown that social judgement may be defined by two dimensions, competence and warmth. From a functional perspective, embodied theories have proposed that warmth may be associated with physical distance, whereas competence may be connected to a vertical motion (UPWARD/DOWNWARD). Two main studies were conducted to examine if approach-avoidance and vertical motion could influence affective judgements about traits representing these two social dimensions. Valence judgements about warmth traits that were moving towards the subject resulted in more positive judgement than when they were moving away (approach/avoidance). Furthermore, competence traits were judged more positively when they moved in an UPWARD direction, compared with when they moved DOWNWARD. A metacognitive account of confidence is offered to explain how cognitions about warmth and competence are connected to the physical world.

Protective buttressing of the human fist and the evolution of hominin hands

The derived proportions of the human hand may provide supportive buttressing that protects the hand from injury when striking with a fist. Flexion of digits 2–5 results in buttressing of the pads of the distal phalanges against the central palm and the palmar pads of the proximal phalanges. Additionally, adduction of the thenar eminence to abut the dorsal surface of the distal phalanges of digits 2 and 3 locks these digits into a solid configuration that may allow a transfer of energy through the thenar eminence to the wrist. To test the hypothesis of a performance advantage, we measured: (1) the forces and rate of change of acceleration (jerk) from maximum effort strikes of subjects striking with a fist and an open hand; (2) the static stiffness of the second metacarpo-phalangeal (MCP) joint in buttressed and unbuttressed fist postures; and (3) static force transfer from digits 2 and 3 to digit 1 also in buttressed and unbuttressed fist postures. We found that peak forces, force impulses and peak jerk did not differ between the closed fist and open palm strikes. However, the structure of the human fist provides buttressing that increases the stiffness of the second MCP joint by fourfold and, as a result of force transfer through the thenar eminence, more than doubles the ability of the proximal phalanges to transmit ‘punching’ force. Thus, the proportions of the human hand provide a performance advantage when striking with a fist. We propose that the derived proportions of hominin hands reflect, in part, sexual selection to improve fighting performance.

Caring for Sharing

Does physical warmth lead to caring and sharing? Research suggests that it does; physically warm versus cold conditions induce prosocial behaviors and cognitions. Importantly, previous research has not traced the developmental origins of the association between physical warmth and affection. The association between physical warmth and sharing may be captured in specific cognitive models of close social relations, often referred to as attachment styles. In line with this notion, and using a dictator game set-up, the current study demonstrates that children who relate to their friends with a secure attachment style are more generous toward their peers in warm than in cold conditions. This effect was absent for children who relate to friends with an insecure attachment style. Notably, however, these children not just always shared less: They allocated more stickers to a friend than to a stranger. These findings provide an important first step to understand how fundamental embodied relations develop early in life. We discuss broader implications for grounded cognition and person perception.

Cold-blooded loneliness: social exclusion leads to lower skin temperatures

Being ostracized or excluded, even briefly and by strangers, is painful and threatens fundamental needs. Recent work by Zhong and Leonardelli (2008) found that excluded individuals perceive the room as cooler and that they desire warmer drinks. A perspective that many rely on in embodiment is the theoretical idea that people use metaphorical associations to understand social exclusion (see Landau, Meier, & Keefer, 2010). We suggest that people feel colder because they are colder. The results strongly support the idea that more complex metaphorical understandings of social relations are scaffolded onto literal changes in bodily temperature: Being excluded in an online ball tossing game leads to lower finger temperatures (Study 1), while the negative affect typically experienced after such social exclusion is alleviated after holding a cup of warm tea (Study 2). The authors discuss further implications for the interaction between body and social relations specifically, and for basic and cognitive systems in general.

Embodied metaphors and creative "acts"

Creativity is a highly sought-after skill. Prescriptive advice for inspiring creativity abounds in the form of metaphors: People are encouraged to "think outside the box", to consider a problem "on one hand, then on the other hand", and to "put two and two together" to achieve creative breakthroughs. These metaphors suggest a connection between concrete bodily experiences and creative cognition. Inspired by recent advances in the understanding of body-mind linkages in the research on embodied cognition, we explored whether enacting metaphors for creativity enhances creative problem solving. Our findings from five studies revealed that both physical and psychological embodiment of metaphors for creativity promoted convergent thinking and divergent thinking (i.e., fluency, flexibility, or originality) in problem solving. Going beyond prior research, which focused primarily on the kind of embodiment that primes preexisting knowledge, we provide the first evidence that embodiment can also activate cognitive processes that facilitate the generation of new ideas and connections.

Lowering the Pitch of Your Voice Makes You Feel More Powerful and Think More Abstractly

Voice pitch may not only influence the listeners but also the speakers themselves. Based on the theories of embodied cognition and previous research on power, we tested whether lowering their pitch leads people to feel more powerful and think more abstractly. In three experiments, participants received instructions to read a text out loud with either a lower or a higher voice than usual. Subsequently, feelings of power (Experiments 1 and 2) and abstract thinking (Experiment 3) were assessed. Participants who lowered their voice pitch perceived themselves more as possessing more powerful traits (Experiments 1 and 2) and had a higher level of abstract thinking (Experiment 3) compared to participants who raised their voice pitch.

Power Posing

Humans and other animals express power through open, expansive postures, and they express powerlessness through closed, contractive postures. But can these postures actually cause power? The results of this study confirmed our prediction that posing in high-power nonverbal displays (as opposed to low-power nonverbal displays) would cause neuroendocrine and behavioral changes for both male and female participants: High-power posers experienced elevations in testosterone, decreases in cortisol, and increased feelings of power and tolerance for risk; low-power posers exhibited the opposite pattern. In short, posing in displays of power caused advantaged and adaptive psychological, physiological, and behavioral changes, and these findings suggest that embodiment extends beyond mere thinking and feeling, to physiology and subsequent behavioral choices. That a person can, by assuming two simple 1-min poses, embody power and instantly become more powerful has real-world, actionable implications.

Synchronous Multisensory Stimulation Blurs Self-Other Boundaries

In a study that builds on recent cognitive neuroscience research on body perception and social psychology research on social relations, we tested the hypothesis that synchronous multisensory stimulation leads to self-other merging. We brushed the cheek of each study participant as he or she watched a stranger’s cheek being brushed in the same way, either in synchrony or in asynchrony. We found that this multisensory procedure had an effect on participants’ body perception as well as social perception. Study participants exposed to synchronous stimulation showed more merging of self and the other than participants exposed to asynchronous stimulation. The degree of self-other merging was determined by measuring participants’ body sensations and their perception of face resemblance, as well as participants’ judgment of the inner state of the other, closeness felt toward the other, and conformity behavior. The results of this study show how multisensory integration can affect social perception and create a sense of self-other similarity.
