Observers predict actions from facial emotional expressions during real-time social interactions

In face-to-face social interactions, emotional expressions provide insights into the mental state of an interactive partner. This information can be crucial to infer action intentions and react towards another person’s actions. Here we investigate how facial emotional expressions impact subjective experience and physiological and behavioral responses to social actions during real-time interactions. Thirty-two participants interacted with virtual agents while fully immersed in Virtual Reality. Agents displayed an angry or happy facial expression before they directed an appetitive (fist bump) or aversive (punch) social action towards the participant. Participants responded to these actions, either by reciprocating the fist bump or by defending the punch. For all interactions, subjective experience was measured using ratings. In addition, physiological responses (electrodermal activity, electrocardiogram) and participants’ response times were recorded. Aversive actions were judged to be more arousing and less pleasant relative to appetitive actions. In addition, angry expressions increased heart rate relative to happy expressions. Crucially, interaction effects between facial emotional expression and action were observed. Angry expressions reduced pleasantness stronger for appetitive compared to aversive actions. Furthermore, skin conductance responses to aversive actions were increased for happy compared to angry expressions and reaction times were faster to aversive compared to appetitive actions when agents showed an angry expression. These results indicate that observers used facial emotional expression to generate expectations for particular actions. Consequently, the present study demonstrates that observers integrate information from facial emotional expressions with actions during social interactions.

A fist bump in a political meeting? The influence of social context on affordance selection

Historically, understanding human cognition such as action processing has been a challenging issue in cognitive neuropsychology and the more we know about cognition, the more we shape it as a complex, multi-determined phenomenon that is embedded in a social context. The present study aimed at understanding how the social context could influence affordance selection. We hypothesized that affordance selection would be modulated by social context and that a given hand configuration would be considered appropriate or not, as a function of the presence or absence of social context. Twenty-six healthy participants were asked to judge the appropriateness of three variants of 10 hand-object interactions based on photographs presented with or without a visual, social context. In our results, hand configurations were intrinsically acceptable or not, but this effect was modulated by the social context. A three-step model of the influence of social context on affordance selection was proposed, according to which selection depends on social norms, in the form of social knowledge and social context analysis.

Transfer of methicillin-resistant Staphylococcus aureus by fist bump versus elbow bump.

For 40 patients with methicillin-resistant Staphylococcus aureus (MRSA) colonization, fist bump and elbow bump greetings resulted in frequent transfer of MRSA (25% vs 15%, respectively), but significantly fewer colonies were transferred via the elbow bump. Noncontact greetings should be encouraged to reduce the risk of transfer of healthcare-associated pathogens.

What’s in a Handshake? Exploring the Best Form of Greeting to Prevent Hand to Hand Spread of Viruses

Background: Respiratory and enteric viruses are highly contagious pathogens that can be spread by contaminated hands and surfaces. We hypothesized that alternatives to handshake greetings that reduce the time and surface area of hand contact would be associated with decreased transfer of viral particles. Methods: In a simulation of hand-contact greetings, volunteers (N = 22) used a keyboard contaminated with the benign bacteriophage MS2 and then performed a handshake and fist bump with additional volunteers. To assess viral transfer, hands were cultured for MS2, and plaque-forming units (PFU) were compared for the different types of hand contact. Additional simulations (N = 10) were conducted to compare viral transfer with the fist bump versus a cruise tap greeting (ie, a modified fist bump involving single knuckle contact). Results: The handshake greeting resulted in significantly greater transfer of MS2 than the fist bump (1.31 vs 0.54 log10 PFUs, P < .001) (Fig. 1A), but the frequency of transfer of virus was high for both greetings (91% transfer by handshake vs 59% by fist bump). The cruise-tap greeting did not result in reduced transfer of viral particles in comparison to the fist bump (Fig. 1B), and the frequency of transfer remained high (70%). Conclusions: The fist-bump and cruise-tap greetings could potentially reduce transmission of viruses in comparison to the handshake, but transfer occurred frequently, even with these greeting methods. To eliminate hand-to-hand transmission of respiratory and enteric viruses, alternative greeting methods that do not involve physical contact are needed.Funding: NoneDisclosures: None

Does the Fist Bump Transfer Less Methicillin-Resistant Staphylococcus aureus Than a Handshake?

Background: Contaminated hands are the most important source for transmission of pathogens in healthcare settings. It has been proposed that replacing the handshake with alternative greetings such as the fist bump might reduce the risk for pathogen transmission. Methods: In a cohort of 50 patients with methicillin-resistant Staphylococcus aureus (MRSA) colonization, we compared the frequency of transfer of MRSA by handshake versus fist bump versus cruise tap (ie, a modified fist bump involving knuckle-to-knuckle contact with a single finger). MRSA-colonized patients performed each greeting with research personnel wearing sterile gloves, and cultures were obtained to determine the number of colonies transferred. Transfer by handshake was also assessed after MRSA-colonized patients used alcohol-based hand sanitizer. Quantitative cultures were obtained to compare the burden of MRSA on the palm versus dorsum of the hands of the MRSA carriers. Results: As shown in Fig. 1, there was a significant reduction in the frequency of MRSA transfer for the cruise tap compared to the handshake, but not for the fist bump. Use of alcohol-based hand sanitizer by MRSA carriers also significantly reduced the risk for transfer of MRSA. There was no significant difference in the burden of MRSA on the dorsum versus the palm of the hands (mean +SE colonies recovered, 32.7+12.3 vs 27.3+12.7; P > .05). Conclusions: The fist-bump greeting did not transfer less MRSA than a handshake. However, transfer was significantly reduced by a cruise-tap greeting or by handshake after the use of hand sanitizer. Modified greetings and patient hand hygiene are potential strategies to reduce transmission of healthcare-associated pathogens.Funding: NoneDisclosures: None

Transfer of methicillin-resistant Staphylococcus aureus by fist bump versus handshake.

For patients with methicillin-resistant Staphylococcus aureus (MRSA) colonization, a traditional fist-bump greeting did not significantly reduce MRSA transfer in comparison to a handshake. However, transfer was reduced with a modified fist bump that minimized the surface area of contact and when hand hygiene was performed before the handshake.

Understanding the visual perception of awkward body movements: How interactions go awry

Dyadic interactions can sometimes elicit a disconcerting response from viewers, generating a sense of "awkwardness." Despite the ubiquity of awkward social interactions in daily life, it remains unknown what visual cues signal the oddity of human interactions and yield the subjective impression of awkwardness. In the present experiments, we focused on a range of greeting behaviors (handshake, fist bump, high five) to examine both the inherent objectivity and impact of contextual and kinematic information in the social evaluation of awkwardness. In Experiment 1, participants were asked to discriminate whether greeting behaviors presented in raw videos were awkward or natural, and if judged as awkward, participants provided verbal descriptions regarding theawkward greeting behaviors. Participants showed consensus in judging awkwardness from raw videos, with a high proportion of congruent responses across a range of awkward greeting behaviors. We also found that people used social-related and motor-related words in their descriptions for awkward interactions. Experiment 2 employed advanced computer vision techniques to present the same greeting behaviors in three different display types. All display types preserved kinematic information, but varied contextual information: (1) patch displays presented blurred scenes composed of patches; (2) body displays presented human body figures on a black background; and (3) skeleton displays presented skeletal figures of moving bodies. Participants rated the degree of awkwardness of greeting behaviors. Across display types, participants consistently discriminated awkward and natural greetings, indicating that the kinematics of body movements plays an important role in guiding awkwardness judgments. Multidimensional scaling analysis based on the similarity of awkwardness ratings revealed two primary cues: motor coordination (which accounted for most of the variability in awkwardness judgments) and social coordination. We conclude that the perception of awkwardness, while primarily inferred on the basis of kinematic information, is additionally affected by the perceived social coordination underlying human greeting behaviors.

Ban the handshake in winter?

Gastrointestinal and respiratory viruses are particularly common during winter months, and reducing risk of transmission is challenging. Transfer of bacteria from the hands of one person to another is dramatically reduced with a fist bump compared to a handshake. If the same is true for viruses, should we recommend this change in greeting in the winter?

Handshaking forbidden in hospitals

Handshaking forbidden in hospitals. The handshake may transmit infectious organisms. The transfer of microorganisms during usual forms of greetings (high five, fist bump and handshake with variable duration and pressure) was measured indicating that the fist bump is the safer form of greeting. A handshake-free zone was implemented in UCLA hospital and supported by healthcare professionals and parents of babies admitted to the Neonatal Intensive Care Unit.

Address to the Eastern Group Psychotherapy Society Training Program Graduating Class of 2016

Address to the Eastern Group Psychotherapy Society Training Program Graduating Class of 2016 Michael Altshuler1 issn 0362-4021 © 2016 Eastern Group Psychotherapy Society group, Vol. 40, No. 3, Fall 2016 241 1 Private practice, Hastings-on-Hudson, New York. Correspondence should be addressed to Michael Altshuler, LCSW, CGP, 21 Jefferson Avenue, Hastings-on-Hudson, NY 10706. E-mail: altshulermichael@gmail.com. Good evening, everyone: invited guests, distinguished faculty, and, of course, you, the graduates of the 2016 Training Program. I am pleased to be here as you celebrate your wonderful achievement. It is an honor to salute your accomplishment and to welcome you as new colleagues. “THERE’S MORE TO DO?!” My theme tonight is the continuing education of the group leader. Some of you may balk at the thought of this. “Continuing! How could I possibly do more than I’ve already done?” If this topic evokes consternation, then think of my words as an invitation for future consideration. For those of you, however, still engaged in the sustaining embrace of group life, think of my words as a fist bump of recognition. In either case, let me begin with a question: Can you recall what you were doing at this time in 1992? Twenty-four years ago tonight, I was at my graduation from the Training Program—something I remember well. I recall, for example, my jealousy of the person chosen over me to represent our experiential group. Despite what I thought was my well-concealed fear of public speaking, I credit the wisdom of the group for joining my defenses and choosing someone else. I also recall how guilty I felt in the months before graduation, because I had stopped doing the assigned readings. I reveal this now, because the requirement to feel badly about it has surely passed. 242 altshuler But these memories are minor compared to the excitement I felt at completing the program and receiving what I viewed as my license to drive. I was on the road to becoming a Certified Group Therapist. My mother was happy. My wife was relieved. And for me, the productive weekly torture of exposing myself to fellow group members—a task one friend called “talking naked for the sake of professional development ”—was done. The rewarding misery of being a group member, though always illuminating, was now behind me! Or so I thought. After all, hadn’t the Training Program provided a solid foundation? Hadn’t it introduced me to the basics of group therapy and acquainted me with the tools needed to become a respectable group leader? Yes, it had. But I was wrong to assume that my education in the world of group was over. If I wanted to emerge from my agency practice at the time and discover where I fit—into what I perceived as the forbidding guild of successful group therapists (those whose papers I admired, whose books formed a shrine on my shelf)—I had to concede that there was more to learn. What I couldn’t know on that night in 1992 was that my wish to master the art of leading successful groups would be delayed because life had a different plan for me. DERAILED AND RERAILED During the last semester of the Training Program, my second daughter, Alice, was born. She was seven weeks premature, and within days of her birth, it was clear that something was terribly wrong. After much uncertainty and worry, my wife and I learned that Alice was born with a rare genetic disorder. We were told that there were only 400 known cases in the world. It was not detectable beforehand and not curable at any stage. This, however, is not the time to elaborate on Alice’s diagnosis or to suggest that being her dad made me a better person. Suffice it to say that from the moment we learned of Alice’s condition, neither she, my wife, nor I have lived free of the limitations and challenges that her physical and emotional needs placed, and continue to place, upon us. So why do I tell you this on your special night? Well, several years ago, when she was nearly 19, Alice...

“Can I Make Any Difference?” Gang Affiliation, the School-to-Prison Pipeline, and Implications for Teachers

After one of my students correctly answered a question that everyone else was struggling with, I eagerly approached him to give him a high five or fist bump, which was apparently not hip enough for him. Instead, he suggested we do a different kind of handshake involving a lot of different twists, finger combinations, and intricate patterns. By being included in this handshake, I felt like after two short weeks my students were beginning to accept me and were welcoming me into their personal lives. Little did I know that I had just participated in a gang affiliated handshake; the class erupted in laughter and I was told I was gangbangin' and officially a part of the clique, aware of their secret knowledge (Researcher Journal, 2 October).In this situation, what should a teacher do? Clearly the students found this moment funny and interactive, an invitation into their lives through a display of extra-curricular language and action. However, a teacher might be concerned that handshakes and signs representing gang affiliation might be used by others to criminalize students within a school setting (Butler et al., 2012; Gregory, Skiba, & Noguera, 2010; Noguera, 2003; Skiba, Rausch, & Ritter, 2004). The question, What should a teacher do?, when gang issues and identities enter the classroom only scratches the surface: Are my students involved in gangs? How might that involvement (real or perceived) affect their education? How might that involvement (real or perceived) affect the way disciplinary policies push them into the school-to-prison pipeline? How might I disrupt the school-to-prison pipeline? Can I make any difference?Over the course of a year, the researcher wrestled with these questions, engaging action research to explore how to disrupt the school-to-prison pipeline through a curriculum purposively designed to generate dialogue around gangs and gang affiliations. This report of research opens with a review of literature defining the school-to-prison pipeline and its connections to gang affiliation. The study engaged methods of qualitative action research to record and analyze the researcher's experiences as a high school English teacher in dialogue around gang affiliation with adolescent male students experiencing criminalized schools. Findings provided some hope that teachers might play a role in disrupting the school-to-prison pipeline but that strong student-teacher relationships are necessary. Implications describe how other teachers wanting to disrupt the schoolto-prison pipeline might use curricula that spark discussions around gangs.DEFINING GANGThere is no internationally accepted definition of the word gang (Howell & Griffiths, 2016), but even in this article it has already been used it as if a reader will intuit its meaning. Current federal law defines a criminal street gang as anongoing group, club, organization, or association of five or more persons that has as one of its primary purposes the commission of... a federal felony involving a controlled substance...; a federal felony crime of violence that has as an element the use or attempted use of physical force against the person of another; and a conspiracy to commit an offense. (18 USC § 521 [a, c])While researchers are not always specific about drug crime or violence in using the word gang, the historical development of gangs from the 1980s to the present must recognize the effect of the international drug trade on local gangs (Toldson, 2012). Other labels used in the research include adolescent gangs (Mallett, 2015), street gangs (Toldson, 2012), and delinquent peer groups (Barnert et al., 2015). In this article, the word gang connotes all of these possibilities because the participants in this study used the word gang to describe such groups. When referring to students with gang affiliations, the students claimed those affiliations; there were no assumptions that the participants were involved in delinquent or criminal activity. …

The fist bump: A more hygienic alternative to the handshake

The handshake is a commonplace greeting in many cultures, but it has the potential to transmit infectious organisms directly between individuals. We developed an experimental model to assay transfer of bacteria during greeting exchange, and show that transfer is dramatically reduced when engaging in alternative so-called dap greetings known as the high five and fist bump compared with a traditional handshake. Adoption of the fist bump as a greeting could substantially reduce the transmission of infectious disease between individuals.

Reducing pathogen transmission in a hospital setting. Handshake verses fist bump: a pilot study

Handshaking is a known vector for bacterial transmission between individuals. Handwashing has become a major initiative throughout healthcare systems to reduce transmission rates, but as many as 80% of individuals retain some disease-causing bacteria after washing. The fist bump is an alternative to the handshake that has become popular. We have determined that implementing the fist bump in the healthcare setting may further reduce bacterial transmission between healthcare providers by reducing contact time and total surface area exposed when compared with the standard handshake.

Bumps and Tears on the Road to the Presidency: Media Framing of Key Nonverbal Events in the 2008 Democratic Election

Two nonverbal “events” leading up to the nomination of the Democratic presidential candidate in the 2008 election, Hillary Clinton's “tears” and Barack and Michelle Obama's “fist bump,” were the subject of news media discussion. This discourse provides a sense of the diverse ways the media framed these nonverbal cues, their communicative functions, and the social commentary implied in these framings. We found one common frame in the discourse of both events: an informative frame in which the behavior is discussed as an “authentic” reflection of the candidate. A performative frame was seen in the discourse surrounding the tears. Both of these frames speak to the challenges of emotional expression in U.S. politics, particularly for women. For the bump, an additional frame not discussed in previous literature was labeled interpretive, in which the discussion focused primarily on accessing or debating the arbitrarily derived meaning of the behavior, a relatively “safe” way of handling a potentially race-based cue.
