AbstractVirus mitigation behavior has been and still is a powerful means to fight the COVID‐19 pandemic irrespective of the availability of pharmaceutical means (e.g., vaccines). We drew on health behavior theories to predict health‐protective (coping‐specific) responses and hope (coping non‐specific response) from health‐related cognitions (vulnerability, severity, self‐assessed knowledge, efficacy). In an extension of this model, we proposed orientation to internal (problem‐focused coping) and external (country capability) coping resources as antecedents of health protection and hope; health‐related cognitions were assumed as mediators of this link. We tested these predictions in a large multi‐national multi‐wave study with a cross‐sectional panel at T1 (Baseline, March‐April 2020; N = 57,631 in 113 countries) and a panel subsample at two later time points, T2 (November 2020; N = 3097) and T3 (April 2021; N = 2628). Multilevel models showed that health‐related cognitions predicted health‐protective responses and hope. Problem‐focused coping was mainly linked to health‐protective behaviors (T1‐T3), whereas country capability was mainly linked to hope (T1‐T3). These relationships were partially mediated by health‐related cognitions. We conceptually replicated predictions of health behavior theories within a real health threat, further suggesting how different coping resources are associated with qualitatively distinct outcomes. Both patterns were consistent across countries and time.

The present study examined the extent to which a key marker of task conflict, negative facilitation, is modified by onset complexity. Negative facilitation, slower reaction times (RTs) to congruent stimuli than to non-lexical neutral stimuli in the Stroop task, is thought to reflect competition between the task sets of colour naming and word reading in the Stroop task (also known as task conflict). That is, it reflects competition between whole task sets, over and above any competition between specific responses associated with a stimulus. An alternative account of negative facilitation argues that it reflects the specific phonological processing differences between pronounceable (e.g., congruent) and non-pronounceable (e.g., xxxx) stimuli that are magnified by the specific task contexts that produce negative facilitation (a mostly non-lexical trial context). Here we used onset complexity to manipulate pronounceability of the irrelevant words in the Stroop task to test this alternative account. However, before applying manipulations that produce negative facilitation, we initially tested whether there was an effect of onset complexity on Stroop task performance. The results from Experiment(s) 1 (and 3) showed that complex onsets led to larger positive facilitation and congruency effects relative to simple onsets, but did not modify incongruent or neutral-word RTs. Experiment 2 directly tested whether onset complexity modifies negative facilitation and provided strong evidence for no effect of onset complexity, contrary to the alternative account predictions. The implications of the results for task conflict theory, selective attention, and phonological processing in the manual response Stroop task are discussed.

Under threat, the combinations of fearful display and gaze orientation emitted by others can provide crucial information about the presence and location of the danger, as well as whether other individuals are in distress and need help. While it has been shown that threat-induced anxiety facilitates the processing of fearful faces, the question remains as to whether the processing of one of the two combinations of fearful displays and gaze direction (signaling danger vs. need for help) is prioritized within a threatening environment. To address this question, we ran two experiments. In a first online experiment, we showed that fearful displays associated with averted and direct gaze are appraised as preferentially signaling danger and need for help, respectively. In a second experiment, participants performed a fear categorization task (neutral vs. fear faces), manipulating gaze direction and intensity levels of facial expressions, under two alternating contexts: one involving exposure to unpredictable distress screams (threat condition) and the other being a nonthreat control condition. In threat blocks, participants had a higher tendency to interpret averted faces as expressing fear. Drift-diffusion analyses revealed that this resulted from the combined increase in drift rate and threshold. Our findings showed that threat-induced anxiety leads to prioritized processing of averted over direct fearful facial displays, assigning processing priority to social signals that convey information about the presence and location of potential danger.

Some public officials have expressed concern that policies mandating collective public health behaviors (e.g., national/regional "lockdown") may result in behavioral fatigue that ultimately renders such policies ineffective. Boredom, specifically, has been singled out as one potential risk factor for noncompliance. We examined whether there was empirical evidence to support this concern during the COVID-19 pandemic in a large cross-national sample of 63,336 community respondents from 116 countries. Although boredom was higher in countries with more COVID-19 cases and in countries that instituted more stringent lockdowns, such boredom did not predict longitudinal within-person decreases in social distancing behavior (or vice versa; n = 8,031) in early spring and summer of 2020. Overall, we found little evidence that changes in boredom predict individual public health behaviors (handwashing, staying home, self-quarantining, and avoiding crowds) over time, or that such behaviors had any reliable longitudinal effects on boredom itself. In summary, contrary to concerns, we found little evidence that boredom posed a public health risk during lockdown and quarantine. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

AbstractResearch in social psychology and education proposes that adopting a growth mindset of intelligence is an important mediator for the well-being and performance of students at school. As a consequence, wise interventions have been developed to target student mindsets and change their beliefs about how much their intelligence can grow with training and experience. However, the efficacy of mindset interventions is highly debated, as effect sizes vary widely across studies. Here, we hypothesized that the study environment and, in particular, the teacher’s mindset about intelligence is an important moderator of mindset intervention efficacy. We tested this hypothesis by randomly assigning six middle schools from underprivileged neighborhoods in the Paris area in France to a no intervention condition, a condition with mindset interventions delivered only to the students, and a condition with mindset interventions for teachers and students. The results show that the combined teacher and student mindset intervention condition was the most efficient for increasing the student’s growth mindset. This finding suggests that a short and easy-to-implement mindset intervention for teachers can help students develop a growth mindset.

To contain and curb the spread of COVID-19, the governments of countries around the world have used different strategies (lockdown, mandatory vaccination, immunity passports, voluntary social distancing, etc). This study aims to examine the reactions produced by the public announcement of a binding political decision presented by the president of the French Republic, Emmanuel Macron, on July 12, 2021, which imposed vaccination on caregivers and an immunity passport on all French people to access restaurants, cinemas, bars, and so forth. To measure these announcement reactions, 901,908 unique tweets posted on Twitter (Twitter Inc) between July 12 and August 11, 2021, were extracted. A neural network was constructed to examine the arguments of the tweets and to identify the types of arguments used by Twitter users. This study shows that in the debate about mandatory vaccination and immunity passports, mostly "con" arguments (399,803/847,725, 47%; χ26=952.8; P<.001) and "scientific" arguments (317,156/803,583, 39%; χ26=5006.8; P<.001) were used. This study shows that during July and August 2021, social events permeating the public sphere and discussions about mandatory vaccination and immunity passports collided on Twitter. Moreover, a political decision based on scientific arguments led citizens to challenge it using pseudoscientific arguments contesting the effectiveness of vaccination and the validity of these political decisions.

Patients hospitalised with acute venous thromboembolism (VTE), and notably patients with pulmonary embolism, often remain in hospital for extended periods due to the perceived risk of complications. However, several studies have shown that home treatment of selected patients is feasible and safe, with a low incidence of adverse events. This may offer clear benefits for patients’ quality of life, hospital planning and cost to the health service. Nonetheless, there is a need for a VTE risk-stratification tool specifically addressing prognosis in patients with cancer. This may aid in the selection of low-risk patients with cancer and VTE who are suitable for outpatient treatment. Although several prognostic scores have been proposed, we suggest using a pragmatic clinical decision-making tool such as the Hestia criteria for selecting patients for home care in everyday clinical practice. Once patients have been discharged, it is mandatory to monitor patients regularly (we suggest after 3 days, 10 days, 1 month and 3 months, or more frequently if needed) with the involvement of a multidisciplinary team, so that appropriate and timely remedial action can be taken in case of warning signs of complications. If patients are selected carefully and monitored effectively, many patients who experience acute VTE can be cared for safely at home.

Patients with cancer are at significantly increased risk of venous thromboembolism (VTE), due both to the impact of malignant disease itself and to the impact of certain anticancer drugs on haemostasis. This is true both for first episode venous thromboembolism and recurrence. The diagnosis and management of VTE recurrence in patients with cancer poses particular challenges, and these are reviewed in the present article, based on a systematic review of the relevant scientific literature published over the last decade. Furthermore, it is uncertain whether diagnostic algorithms for venous thromboembolism, validated principally in untreated non-cancer patients, are also valid in anticoagulated cancer patients: the available data suggests that clinical decision rules and D-dimer testing perform less well in this clinical setting. In patients with cancer, computed tomography pulmonary angiography and venous ultrasound appear to be the most reliable diagnostic tools for diagnosis of pulmonary embolism and deep vein thrombosis respectively. Options for treatment of venous thromboembolism include low molecular weight heparins (at a therapeutic dose or an increased dose), fondaparinux or oral direct factor Xa inhibitors. The choice of treatment should take into account the nature (pulmonary embolism or VTE) and severity of the recurrent event, the associated bleeding risk, the current anticoagulant treatment (type, dose, adherence and possible drug-drug interactions) and cancer progression.

The introduction of emerging technologies is often an opportunity to redesign the workstation. The Enabling Collaborative Situation (ECS) is a theoretical proposal that aims to deploy the operator’s activity in a collaborative situation with an emerging technology. This approach often seems to be neglected by designers. It is a practical tool for industrialists to guide the design of new work situations as well as for the evaluation of existing situations. An experiment was designed to reproduce a consignment operation. The initial situation corresponded to a classic situation with a paper-based operating procedure. The second situation was assisted by an augmented reality (AR) device and corresponded to either a good intensity of ECS or a low intensity of ECS (which is classically observed in a factory). This study has succeeded in creating an ECS, and it is well perceived as such by the subjects, but the different improvements are not perceived as important enough to make the overall experience better (satisfaction, comprehension, accessibility, performance, etc.). As it was a first attempt, the transformations of the situation were limited. This low intensity of change may explain some of the results of the experiment, but this first attempt also shows the originality and the interest of this work.
