Social Responses to Expressive Suppression: The Role of Personality Judgments

Why do people who suppress their emotion-expressive behavior have difficulty forming close, supportive relationships? Previous studies have found that suppression disrupts the dynamics of social interactions and existing relationships. We evaluated a complementary hypothesis: that suppression functions as a behavioral cue leading others to form negative personality impressions of suppressors, even at zero-acquaintance. In 2 studies, participants reported personality judgments and other impressions of targets who either suppressed or expressed their emotion-expressive behavior in response to amusing or sad film clips. In findings replicated across studies, targets who suppressed either amusement or sadness were judged as less extraverted, less agreeable, and more interpersonally avoidant and anxious than targets who expressed emotions, and participants were less interested in affiliating with suppressors compared with expressers. Effects were amplified when targets suppressed amusement (compared with sadness) and when participants knew the emotional context (compared with when they did not) and, thus, could form expectations about what emotions targets should be showing. Extraversion and agreeableness judgments mediated the effect of suppression on participants’ disinterest in affiliating. In Study 2, which extended Study 1 in several ways, effects were pronounced for the enthusiasm aspect of extraversion and the compassion aspect of agreeableness. We also found evidence that judgments of suppressors do not simply fall between neutral and fully expressing targets; rather, judgments of suppressors are qualitatively different. We discuss implications for understanding the social consequences of emotion regulation—in particular, how beyond disrupting relationships, suppression may prevent some relationships from even forming in the first place.

Mechanosensitive Regulation of Fibrosis

Cells in the human body experience and integrate a wide variety of environmental cues. A growing interest in tissue mechanics in the past four decades has shown that the mechanical properties of tissue drive key biological processes and facilitate disease development. However, tissue stiffness is not only a potent behavioral cue, but also a product of cellular signaling activity. This review explores both roles of tissue stiffness in the context of inflammation and fibrosis, and the important molecular players driving such processes. During inflammation, proinflammatory cytokines upregulate tissue stiffness by increasing hydrostatic pressure, ECM deposition, and ECM remodeling. As the ECM stiffens, cells involved in the immune response employ intricate molecular sensors to probe and alter their mechanical environment, thereby facilitating immune cell recruitment and potentiating the fibrotic phenotype. This powerful feedforward loop raises numerous possibilities for drug development and warrants further investigation into the mechanisms specific to different fibrotic diseases.

Courtship behavior as a war of attrition in a simultaneous hermaphrodite

In outcrossing hermaphrodites with unilateral mating, where for each mating interaction one individual assumes the female role and the other the male role, each individual must take a sexual role opposite to that of its partner. In the polychaete worm Ophryotrocha diadema, the decision on sexual role is likely at stake during the day-long courtship. Here we describe, for the first time, courtship and pseudocopulation in this species, quantify their pre-copulatory behavior, and search for behavioral traits predicting the prospective sexual role (i.e., behavioral sexual dimorphism), by analyzing the courtship behavior of pairs of worms during the day preceding a mating event. We did not find any behavioral cue predicting the sexual role worms were to play; partners’ pre-copulatory behaviors were qualitatively and quantitatively symmetrical. We interpret this as the outcome of a war of attrition where partners share the preference for the same sexual role, and both hide their ‘willingness’ to play the less preferred one, until one individual reaches its cost threshold and accepts the less preferred sexual role.

Predictive Behavioral Cues of Patient Violence in the Emergency Department

<p>Nurses are often subject to violence at the hands of their patients. The Emergency Department (ED) has become the area most vulnerable in the hospital setting, with contributing factors including the rise of polysubstance drug abuse, the increasing psychiatric population, and overall stressors related to the economy. The ED is the “gateway” to the availability of shelter, medications, and resources for many people that pass through every year. Accurate and timely identification of the most common and easily identifiable precursors of violence is essential in order to develop and implement effective de-escalation techniques that have the potential to reduce actual events. The purpose of this research project was to demonstrate the usefulness of a behavioral cue assessment tool in providing a simple predictor for potential violence in the ED setting. The methodology included a behavioral assessment checklist containing 17 cues developed by Wilkes, Mohan, Luck and Jackson (2010). Nurses completed the 17 item behavioral assessment on all patients being treated in the ED during a three-week time period. All 17 behavioral cues demonstrated a positive predictive factor for violence based on statistical analysis. Given the simplicity, cost effective nature, and predictability, the checklist appears to be feasible to use to potentially reduce healthcare costs related to injuries and emotional distress of nurses at the hands of violent patients. Further research is indicated. This study further exemplifies the qualities of an advanced practice registered nurse (APRN), including research, education, cost containment, and improved patient care.</p>
