RESUMO

The psychomotrician is a healthcare professional trained in mind-body approaches. They take into account sensoriality, motor skills, cognition, psyche and emotions in relation to the individual's environment and the expression of disorders. It  is an integral part of the treatment of post-traumatic stress disorder. For some years now, psychomotricians have been part of volunteer teams in medical-psychological emergency units, where they offer an integrative approach. Using the body and mediation as their working tools, they rely on non-verbal communication and body language to bring the patient back to the present moment within a reassuring framework.

RESUMO

Most child studies on emotion perception used faces and speech as emotion stimuli, but little is known about children's perception of emotions conveyed by body movements, that is, emotional body language (EBL). This study aimed to investigate whether processing advantages for positive emotions in children and negative emotions in adults found in studies on emotional face and term perception also occur in EBL perception. We also aimed to uncover which specific movement features of EBL contribute to emotion perception from interactive dyads compared with noninteractive monads in children and adults. We asked 5-year-old children and adults to categorize happy and angry point-light displays (PLDs), presented as pairs (dyads) and single actors (monads), in a button-press task. By applying representational similarity analyses, we determined intra- and interpersonal movement features of the PLDs and their relation to the participants' emotional categorizations. Results showed significantly higher recognition of happy PLDs in 5-year-olds and of angry PLDs in adults in monads but not in dyads. In both age groups, emotion recognition depended significantly on kinematic and postural movement features such as limb contraction and vertical movement in monads and dyads, whereas in dyads recognition also relied on interpersonal proximity measures such as interpersonal distance. Thus, EBL processing in monads seems to undergo a similar developmental shift from a positivity bias to a negativity bias, as was previously found for emotional faces and terms. Despite these age-specific processing biases, children and adults seem to use similar movement features in EBL processing.

RESUMO

The pelvic floor forms the primary bottom tissue of the pelvic cavity. It comprises muscles that play a fundamental role in bowel and bladder emptying. Alterations of pelvic floor muscles will result in dysfunctions such as urinary incontinence (UI). Given the high prevalence of UI and its impact on the quality of life (QoL) in patients with pelvic floor muscle dysfunctions, it is necessary to implement public, community, and generalized programs focused on treating these dysfunctions. OBJECTIVE: To determine the effect of a community rehabilitation program on QoL, UI severity, and pelvic floor muscle strength in patients with UI. PATIENTS AND METHOD: A descriptive prospective cohort study. Twenty subjects between 44 and 75 years old with a diagnosis of UI, participants of a community kinesic rehabilitation program on the pelvic floor in Maipú, Santiago, Chile, were evaluated. These volunteers were intervened for six months, and QoL was measured with the 36-Item Short-Form Health Survey (SF-36) and International Consultation on Incontinence Questionnaire Short-Form (ICIQ-SF) scales, UI severity with the Sandvick test, and pelvic floor muscle strength with the Oxford scale. Patients were followed up three months post-intervention. RESULTS: Significant improvements were observed in all scales after applying for the community kinesic rehabilitation program, and the changes were maintained at a 3-month follow-up. CONCLUSIONS: Since the improvement in QoL, UI severity, and pelvic floor muscle strength after the intervention, it is relevant to consider the implementation of community programs aimed at education, screening, and early rehabilitation of these patients.

RESUMO

Adaptive social behavior and mental well-being depend on not only recognizing emotional expressions but also, inferring the absence of emotion. While the neurobiology underwriting the perception of emotions is well studied, the mechanisms for detecting a lack of emotional content in social signals remain largely unknown. Here, using cutting-edge analyses of effective brain connectivity, we uncover the brain networks differentiating neutral and emotional body language. The data indicate greater activation of the right amygdala and midline cerebellar vermis to nonemotional as opposed to emotional body language. Most important, the effective connectivity between the amygdala and insula predicts people's ability to recognize the absence of emotion. These conclusions extend substantially current concepts of emotion perception by suggesting engagement of limbic effective connectivity in recognizing the lack of emotion in body language reading. Furthermore, the outcome may advance the understanding of overly emotional interpretation of social signals in depression or schizophrenia by providing the missing link between body language reading and limbic pathways. The study thus opens an avenue for multidisciplinary research on social cognition and the underlying cerebrocerebellar networks, ranging from animal models to patients with neuropsychiatric conditions.

RESUMO

In social robotics, especially with regard to direct interactions between robots and humans, the robotic movements of the body, arms and head must make an adequate displacement to guarantee an adequate interaction, both from a functional and social point of view. To achieve this, the use of closed-loop control techniques that consider the complex nonlinear dynamics and disturbances inherent in these systems is required. In this paper, an implementation of a nonlinear controller for the tracking of trajectories and a profile of speeds that execute the movements of the arms and head of a humanoid robot based on the mathematical model is proposed. First, the design and implementation of the arms and head are initially presented, then the mathematical model via kinematic and dynamic analysis was performed. With the above, the design of nonlinear controllers such as nonlinear proportional derivative control with gravity compensation, Backstepping control, Sliding Mode control and the application of each of them to the robotic system are presented. A comparative analysis based on a frequency analysis, the efficiency in polynomial trajectories and the implementation requirements allowed selecting the non-linear Backstepping control technique to be implemented. Then, for the implementation, a centralized control architecture is considered, which uses a central microcontroller in the external loop and an internal microcontroller (as internal loop) for each of the actuators. With the above, the selected controller was validated through experiments performed in real time on the implemented humanoid robot, demonstrating proper path tracking of established trajectories for performing body language movements.

RESUMO

Body language is a powerful form of non-verbal communication providing important information about the emotions and intentions of others. The ability to infer other's emotions from their bodily movements and postures recruits an extended network in the brain that encompasses both cortical and subcortical regions. In this chapter, we review recent evidence suggesting that the cerebellum is a critical node of this network. Specifically, we present convergent findings from patients', neuroimaging and non-invasive brain stimulation studies that have shown that the cerebellum is involved in both biological motion perception and in discrimination of bodily emotional expressions. We discuss the potential underlying mechanisms that drive the recruitment of the sensorimotor (anterior) and cognitive (posterior) cerebellum in inferring others' emotions through their bodily movements and postures and how the cerebellum may exert these functions within different cortico-cerebellar and limbic-cerebellar networks dedicated to body language perception.

RESUMO

BACKGROUND: Uncovering patients' biases toward characteristics of anesthesiologists may inform ways to improve the patient-anesthesiologist relationship. The authors previously demonstrated that patients prefer anesthesiologists displaying confident body language, but did not detect a sex bias. The effect of anesthesiologists' age on patient perceptions has not been studied. In this follow-up study, it was hypothesized that patients would prefer older-appearing anesthesiologists over younger-appearing anesthesiologists and male over female anesthesiologists. METHODS: Three hundred adult, English-speaking patients were recruited in the Preanesthesia Evaluation and Testing Center. Patients were randomized (150 per group) to view a set of four videos in random order. Each 90-s video featured an older female, older male, younger female, or younger male anesthesiologist reciting the same script describing general anesthesia. Patients ranked each anesthesiologist on confidence, intelligence, and likelihood of choosing the anesthesiologist to care for their family member. Patients also chose the one anesthesiologist who seemed most like a leader. RESULTS: Three hundred patients watched the videos and completed the questionnaire. Among patients younger than age 65 yr, the older anesthesiologists had greater odds of being ranked more confident (odds ratio, 1.92; 95% CI, 1.41 to 2.64; P < 0.001) and more intelligent (odds ratio, 2.24; 95% CI, 1.62 to 3.11; P < 0.001), and had greater odds of being considered a leader (odds ratio, 2.62; 95% CI, 1.72 to 4.00; P < 0.001) when compared with younger anesthesiologists. The preference for older anesthesiologists was not observed in patients age 65 and older. Female anesthesiologists had greater odds of being ranked more confident (odds ratio, 1.46; 95% CI, 1.13 to 1.87; P = 0.003) and more likely to be chosen to care for one's family member (odds ratio, 1.80; 95% CI, 1.40 to 2.31; P < 0.001) compared with male anesthesiologists. The ranking preference for female anesthesiologists on these two measures was observed among white patients and not among nonwhite patients. CONCLUSIONS: Patients preferred older anesthesiologists on the measures of confidence, intelligence, and leadership. Patients also preferred female anesthesiologists on the measures of confidence and likelihood of choosing the anesthesiologist to care for one's family member.

RESUMO

Effective emotion recognition is imperative to successfully navigating social situations. Research suggests differing developmental trajectories for the recognition of bodily and vocal emotion, but emotions are usually studied in isolation and rarely considered as multimodal stimuli in the literature. When adults are presented with basic multimodal sensory stimuli, the Colavita effect suggests that they have a visual dominance, whereas more recent research finds that an auditory sensory dominance may be present in children under 8 years of age. However, it is not currently known whether this phenomenon holds for more complex multimodal social stimuli. Here we presented children and adults with multimodal social stimuli consisting of emotional bodies and voices, asking them to recognize the emotion in one modality while ignoring the other. We found that adults can perform this task with no detrimental effects on performance regardless of whether the ignored emotion was congruent or not. However, children find it extremely challenging to recognize bodily emotion while trying to ignore incongruent vocal emotional information. In several instances, they performed below chance level, indicating that the auditory modality actively informs their choice of bodily emotion. Therefore, this is the first evidence, to our knowledge, of an auditory dominance in children when presented with emotionally meaningful stimuli.

RESUMO

Children aged about 5 years can use verbal and nonverbal cues to determine social power. However, it is not clear what kinds of nonverbal cues preschoolers can use and whether they can integrate each nonverbal cue with verbal content when determining social power. Therefore, this research examined the ability of Chinese preschoolers to use and integrate visual, auditory, and verbal cues when determining social power as well as how this ability develops with age. In Study 1 (N = 478), 4- to 6-year-old Chinese children were recruited to judge the social power in visual, auditory, content, visual-auditory, visual-content, auditory-content, visual-auditory-content, and neutral cues. The results showed that 4-year-olds could not use any cues, 5-year-olds could not use content cues, and 6-year-olds could use all the cues. Children's performance improved with increasing age and the number of channels. Study 2 (N = 240) investigated whether speech tempo influences children's performance when using content cues. The results showed that 5- and 6-year-olds, but not 4-year-olds, could use content cues to determine social power under normal and slow tempos. Study 3 (N = 80) was conducted to clarify which visual cues 5- and 6-year-olds can use and the age difference. The results revealed that 5- and 6-year-olds could use head, eye, posture, and mixed cues to determine social power, whereas their performance was steady for both 5- and 6-year-olds. In sum, the results show that Chinese children aged about 5 years are already able to use and integrate visual, auditory, and content cues when determining social power. Moreover, the ability to determine social power is gradually improved with age during the preschool period.

RESUMO

Bodily postures are essential to correctly comprehend others' emotions and intentions. Nonetheless, very few studies focused on the pattern of eye movements implicated in the recognition of emotional body language (EBL), demonstrating significant differences in relation to different emotions. A yet unanswered question regards the presence of the "left-gaze bias" (i.e. the tendency to look first, to make more fixations and to spend more looking time on the left side of centrally presented stimuli) while scanning bodies. Hence, the present study aims at exploring both the presence of a left-gaze bias and the modulation of EBL visual exploration mechanisms, by investigating the fixation patterns (number of fixations and latency of the first fixation) of participants while judging the emotional intensity of static bodily postures (Angry, Happy and Neutral, without head). While results on the latency of first fixations demonstrate for the first time the presence of the left-gaze bias while scanning bodies, suggesting that it could be related to the stronger expressiveness of the left hand (from the observer's point of view), results on fixations' number only partially fulfil our hypothesis. Moreover, an opposite viewing pattern between Angry and Happy bodily postures is showed. In sum, the present results, by integrating the spatial and temporal dimension of gaze exploration patterns, shed new light on EBL visual exploration mechanisms.

RESUMO

Nonverbal behavior (NVB) plays an important role in sports. However, it has been difficult to measure, as no coding schemes exist to objectively measure NVB in sports. Therefore, the authors adapted the Body Action and Posture Coding System to the context of soccer penalties, validated it, and initially used this system (Nonverbal Behavior Coding System for Soccer Penalties [NBCSP]) to explore NVB in penalties. Study 1 demonstrated that the NBCSP had good to excellent intercoder reliability regarding the occurrence and temporal precision of NVBs. It also showed that the coding system could differentiate certain postures and behaviors as a function of emotional valence (i.e., positive vs. negative emotional states). Study 2 identified differences in NVB for successful and missed shots in a sample of penalties (time spent looking toward the goal, toward the ground, right arm movement, and how upright the body posture was). The authors discuss the utility of the coding system for different sport contexts.

RESUMO

Since it is generally known that the human body is the best image of the human soul, this paper aims to explain how important body language is when diagnosing psychiatric diagnosis "depression". It is important to point out the importance of other alternative approaches in the treatment of depression when standard psychopharmacotherapy is not enough. Body language is a powerful form of non-verbal communication that provides important traces of intentions, emotions, and motivations in other people. In everyday life, we collect information about what people think and feel by their body posture, manners, and gestures. Evaluations of clinical depression are traditionally based on verbal information. However, non-verbal expressive behavior, related to reflexive feedback of a person, may reveal negative emotional or social processes that are not fully controlled by patients therapy, along with other artistic therapies (art therapy, drama therapy, and music therapy are other artistic therapies that are applied in Great Britain) offers an attractive opportunity for patients because it enables them to work on those issues that are placed on non-verbal and pre-verbal level. Creative psychofarmacotherapy is the concept that involves creativity as its main means. In this context, the importance of physical activity and body movements will be emphasized in the treatment of depression, when regular psychopharmacotherapy is not sufficient. To conclude, the patient has the right to actively take part in creating a therapeutic relationship and responsibly contributes to overcoming psychopathology. The importance of physical activities and body movements is emphasized in the treatment of depressive people. Studies have shown that the anti-depressive effect of physical activity is increased with simultaneous use of antidepressants, as well as that movement therapy and music therapy, together with regular pharmacotherapeutic methods, help with fast recovery and that they can be used in a creative approach to problem-solving.

RESUMO

Body orientation of gesture entails social-communicative intention, and may thus influence how gestures are perceived and comprehended together with auditory speech during face-to-face communication. To date, despite the emergence of neuroscientific literature on the role of body orientation on hand action perception, limited studies have directly investigated the role of body orientation in the interaction between gesture and language. To address this research question, we carried out an electroencephalography (EEG) experiment presenting to participants (n = 21) videos of frontal and lateral communicative hand gestures of 5 s (e.g., raising a hand), followed by visually presented sentences that are either congruent or incongruent with the gesture (e.g., "the mountain is high/low…"). Participants underwent a semantic probe task, judging whether a target word is related or unrelated to the gesture-sentence event. EEG results suggest that, during the perception phase of handgestures, while both frontal and lateral gestures elicited a power decrease in both the alpha (8-12 Hz) and the beta (16-24 Hz) bands, lateral versus frontal gestures elicited reduced power decrease in the beta band, source-located to the medial prefrontal cortex. For sentence comprehension, at the critical word whose meaning is congruent/incongruent with the gesture prime, frontal gestures elicited an N400 effect for gesture-sentence incongruency. More importantly, this incongruency effect was significantly reduced for lateral gestures. These findings suggest that body orientation plays an important role in gesture perception, and that its inferred social-communicative intention may influence gesture-language interaction at semantic level.

RESUMO

The feeling of being addressed is the first step in a complex processing stream enabling successful social communication. Social impairments are a relevant characteristic of patients with major depressive disorder (MDD). Here, we investigated a mechanism which-if impaired-might contribute to withdrawal or isolation in MDD, namely, the neural processing of social cues such as body orientation and gesture. During funtional magnetic resonance imaging (fMRI) data acquisition, 33 patients with MDD and 43 healthy control subjects watched video clips of a speaking actor: one version with a gesture accompanying the speech and one without gesture. Videos were filmed simultaneously from two different viewpoints: one with the actor facing the viewer head-on (frontal) and one side-view (lateral). After every clip, the participants were instructed to evaluate whether they felt addressed or not. Despite overall comparable addressment ratings and a large overlap in activation patterns in MDD and healthy subjects for gesture processing, the anterior cingulate cortex, bilateral superior/middle frontal cortex, and right angular gyrus were more strongly activated in patients than in healthy subjects for the frontal conditions. Our analyses revealed that patients showed specifically higher activation than healthy subjects for the frontal condition without gesture in regions including the posterior cingulate cortex, left prefrontal cortex, and the left hippocampus. We conclude that MDD patients can recognize and interpret social cues such as gesture or body orientation; however, they seem to require more neural resources. This additional effort might affect successful communication and contribute to social isolation in MDD.

RESUMO

It has been proposed that somatosensory reaction to varied social circumstances results in feelings (i.e., conscious emotional experiences). Here, we present two preregistered studies in which we examined the topographical maps of somatosensory reactions associated with violations of different moral concerns. Specifically, participants in Study 1 (N = 596) were randomly assigned to respond to scenarios involving various moral violations and were asked to draw key aspects of their subjective somatosensory experience on two 48,954-pixel silhouettes. Our results show that body patterns corresponding to different moral violations are felt in different regions of the body depending on whether individuals are classified as liberals or conservatives. We also investigated how individual differences in moral concerns relate to body maps of moral violations. Finally, we used natural-language processing to predict activation in body parts on the basis of the semantic representation of textual stimuli. We replicated these findings in a nationally representative sample in Study 2 (N = 300). Overall, our findings shed light on the complex relationships between moral processes and somatosensory experiences.

RESUMO

INTRODUCTION: Disturbed emotion processing is well documented in schizophrenia, but the majority of studies evaluate processing of emotion only from facial expressions. Social cues are also communicated via body posture, and they are similarly relevant for successful social interactions. The aim of the current study was to thoroughly examine body perception abilities in individuals with schizophrenia. METHODS: Fifty-nine patients with schizophrenia and 37 healthy controls completed two tasks of body processing. The first, which was based on the Affect Misattribution Procedure, evaluated implicit processing of bodily emotions, and the second utilised a traditional emotion identification paradigm to assess explicit emotion recognition. RESULTS: Results revealed aberrant implicit processing, but more normative explicit processing, in individuals with schizophrenia. Moderate associations were found between processing of bodies and symptoms of paranoia. Performance on the tasks was not related to cognitive functioning but was associated with clinician-rated social functioning. CONCLUSIONS: Collectively, these results provide information about disturbed processing of bodily emotions in schizophrenia and suggest that these disturbances are associated with the severity of positive symptoms and predict difficulties in everyday social activities and interpersonal relationships.

RESUMO

The cultural and technological achievements of the human species depend on complex social interactions. Nonverbal interpersonal coordination, or joint action, is a crucial element of social interaction, but the dynamics of nonverbal information flow among people are not well understood. We used joint music making in string quartets, a complex, naturalistic nonverbal behavior, as a model system. Using motion capture, we recorded body sway simultaneously in four musicians, which reflected real-time interpersonal information sharing. We used Granger causality to analyze predictive relationships among the motion time series of the players to determine the magnitude and direction of information flow among the players. We experimentally manipulated which musician was the leader (followers were not informed who was leading) and whether they could see each other, to investigate how these variables affect information flow. We found that assigned leaders exerted significantly greater influence on others and were less influenced by others compared with followers. This effect was present, whether or not they could see each other, but was enhanced with visual information, indicating that visual as well as auditory information is used in musical coordination. Importantly, performers' ratings of the "goodness" of their performances were positively correlated with the overall degree of body sway coupling, indicating that communication through body sway reflects perceived performance success. These results confirm that information sharing in a nonverbal joint action task occurs through both auditory and visual cues and that the dynamics of information flow are affected by changing group relationships.

RESUMO

Understanding the brain requires understanding behavior. New machine vision and learning techniques are poised to revolutionize our ability to analyze behaviors exhibited by animals in the laboratory. Here we describe one such method, Motion Sequencing (MoSeq), which combines three-dimensional (3D) imaging with unsupervised machine learning techniques to identify the syllables and grammar that comprise mouse body language. This Q&A situates MoSeq within the array of novel methods currently being developed for behavioral analysis, enumerates its relative strengths and weaknesses, and describes its future trajectory.
