Task-irrelevant emotional expressions are not mimicked, but may modulate the mimicry of task-relevant emotional expressions

Emotional mimicry—the imitation of others’ emotions—is an empathic response that helps to navigate social interactions. Mimicry is absent when participants’ task does not involve engaging with the expressers’ emotions. This may be because task-irrelevant faces (i.e., faces that participants were instructed to ignore) are not processed. To assess whether processed task-irrelevant faces are also not mimicked, we conducted three studies [Study 1: N = 74 participants (27 men; Mage = 26.9 years); Study 2: N = 53 participants (20 men; Mage = 25.8 years); Study 3: N = 51 participants (7 men; Mage = 26.8 years)] using an affective priming paradigm in which one face was task-relevant and one was to be ignored, as a framework to explore the impact of disregarded yet still perceptually processed faces on mimicry. We found that even though both faces were processed, only task-relevant faces were mimicked. Hence, our studies suggest that emotional mimicry depends not only on emotional processing as such but also on the way participants prioritize one piece of information over another. Further, task-irrelevant faces interfered with the mimicry of task-relevant faces. This suggests that even though incongruent task-irrelevant faces do not elicit an empathic (mimicry) response, they still may provide a context that can change the meaning of task-relevant faces and thus impact on the mimicry response

Does smile intensity in photographs really predict longevity?:A replication and extension of Abel and Kruger (2010)

Abel and Kruger (2010) found that the smile intensity of professional baseball players who were active in 1952, as coded from photographs, predicted these players' longevity. In the current investigation, we sought to replicate this result and to extend the initial analyses. We analyzed (a) a sample that was almost identical to the one from Abel and Kruger's study using the same database and inclusion criteria (N = 224), (b) a considerably larger nonoverlapping sample consisting of other players from the same cohort (N = 527), and (c) all players in the database (N = 13,530 valid cases). Like Abel and Kruger, we relied on categorical smile codings as indicators of positive affectivity, yet we supplemented these codings with subjective ratings of joy intensity and automatic codings of positive affectivity made by computer programs. In both samples and for all three indicators, we found that positive affectivity did not predict mortality once birth year was controlled as a covariate

Global tracking of marine megafauna space use reveals how to achieve conservation targets

The recent Kunming-Montreal Global Biodiversity Framework (GBF) sets ambitious goals but no clear pathway for how zero loss of important biodiversity areas and halting human-induced extinction of threatened species will be achieved. We assembled a multi-taxa tracking dataset (11 million geopositions from 15,845 tracked individuals across 121 species) to provide a global assessment of space use of highly mobile marine megafauna, showing that 63% of the area that they cover is used 80% of the time as important migratory corridors or residence areas. The GBF 30% threshold (Target 3) will be insufficient for marine megafauna’s effective conservation, leaving important areas exposed to major anthropogenic threats. Coupling area protection with mitigation strategies (e.g., fishing regulation, wildlife-traffic separation) will be essential to reach international goals and conserve biodiversity.</p

Alveolar Hemorrhage in Antineutrophil Cytoplasmic Antibody-Associated Vasculitis: Results of an International Randomized Controlled Trial (PEXIVAS)

Rationale: Diffuse alveolar hemorrhage (DAH) is a life-threatening manifestation of antineutrophil cytoplasmic antibody–associated vasculitis (AAV). The PEXIVAS (Plasma Exchange and Glucocorticoids in Severe Antineutrophil Cytoplasmic Antibody–Associated Vasculitis) (NCT00987389) trial was the largest in AAV and the first to enroll participants with DAH requiring mechanical ventilation. Objectives: Evaluate characteristics, treatment effects, and outcomes for patients with AAV with and without DAH. Methods: PEXIVAS randomized 704 participants to plasma exchange (PLEX) or no-PLEX and reduced or standard-dose glucocorticoids (GC). DAH status was defined at enrollment as no-DAH, nonsevere, or severe (room air oxygen saturation of ⩽ 85% as measured by pulse oximetry, or use of mechanical ventilation). Measurements and Main Results: At enrollment, 191 (27.1%) participants had DAH (61 severe, including 29 ventilated) and were younger, more frequently relapsing, PR3 (proteinase 3)-ANCA positive, and had lower serum creatinine but were more frequently dialyzed than participants without DAH (n = 513; 72.9%). Among those with DAH, 8/95 (8.4%) receiving PLEX died within 1 year versus 15/96 (15.6%) with no-PLEX (hazard ratio, 0.52; confidence interval [CI], 0.21–1.24), whereas 13/96 (13.5%) receiving reduced GC died versus 10/95 (10.5%) with standard GC (hazard ratio, 1.33; CI, 0.57–3.13). When ventilated, ventilator-free days were similar with PLEX versus no-PLEX (medians, 25; interquartile range [IQR], 22–26 vs. 22–27) and fewer with reduced GC (median, 23; IQR, 20–25) versus standard GC (median, 26; IQR, 25–28). Treatment effects on mortality did not vary by presence or severity of DAH. Overall, 23/191 (12.0%) with DAH died within 1 year versus 34/513 (6.6%) without DAH. End-stage kidney disease and serious infections did not differ by DAH status or treatments. Conclusions: Patients with AAV and DAH differ from those without DAH in multiple ways. Further data are required to confirm or refute a benefit of PLEX or GC dosing on mortality.publishedVersio

On s'intéresse à l'impact de la comparaison sociale, au niveau de l'attractivité physique et de la popularité, sur l'attitude générale d'un individu envers une personne cible. Notre étude a pour but de montrer que l'on peut prédire cette attitude en utilisant la range-frequency theory de Parducci et Wedell

Intensely negative hotspots cause steeper increase in value in the surroundings, possibly overshooting the contrast effect from milder hotspots.

This work is a continuation of our research program about affective judgment in spatial context (Blaison &amp; Hess, 2016). We assume that Intensely negative hotspots cause steeper increase in value in the surroundings, possibly overshooting the contrast effect from milder hotspots
