To contain the SARS-CoV-2 infection rate, health authorities have encouraged the population to enhance protective behaviors such as physical distancing and handwashing. Behavioral sciences emphasize the role of sociocognitive determinants to explain health behaviors, while largely ignoring emotional factors. In a large online study (N > 4000), we investigated the role of sociodemographic, cognitive, emotional, and social factors that can facilitate or hinder handwashing and limitation of social contacts. Data were collected from March 18 until April 19, 2020, which corresponds to the spring lockdown and the first peak of the pandemic in Belgium. Logistic regressions showed that sociodemographic factors (gender, age, level of education) and the dimensions of the Theory of Planned Behavior (intentions, attitudes, perceived behavioral control and subjective norms) had a strong impact on health behaviors, but that emotional factors explained an additional part of the variance. Being more attentive/determined and frightened/anxious , along with scoring higher on health anxiety were related to a higher frequency of handwashing. In contrast, being enthusiastic/happy was related to lower adherence to limiting social contacts. Our results suggest that the type of predictors and the direction of associations depend on the type of health behavior considered. The role of specific emotional factors in addition to more classical predictors is discussed. The study offers new perspectives regarding the factors that are associated with the adherence to behaviors recommended to adopt when faced with a pandemic.

To support the global restart of elective surgery, data from an international prospective cohort study of 8492 patients (69 countries) was analysed using artificial intelligence (machine learning techniques) to develop a predictive score for mortality in surgical patients with SARS-CoV-2. We found that patient rather than operation factors were the best predictors and used these to create the COVIDsurg Mortality Score (https://covidsurgrisk.app). Our data demonstrates that it is safe to restart a wide range of surgical services for selected patients.

Collective memory of historical events can be transmitted across generations not only through cultural memory but also through communicative memory; that is, transmitted by people who have lived through these particular times. Yet, few studies have examined the temporal horizon of a particular type of communicative memory: family historical memories. In this article, we examine the intergenerational transmission of memories from the Second World War in families with an ancestor who resisted during the German Occupation. We interviewed 20 French-speaking Belgian families over three generations. During these individual interviews, participants narrated an anecdote about their ancestor and the Resistance. Then, for the middle and youngest generations, we provided a short cue related to the story chosen by the oldest generation and enquired whether they could tell us the story in their own words. Memory transmission was analysed through two processes: retelling and recalling. Our main result revealed that there was a loss of details across generations, but not complete oblivion. We also found some instances of family myth transmitted across all generations. This study provides evidence that family historical memories fade away after a generation or two, even when these memories describe historical events deemed important for family and society.

Research on future thinking has emphasized how episodic details from memories are combined to create future thoughts, but has not yet examined the role of semantic scripts. In this study, participants recalled how they planned a past camping trip in Australia (past planning task) and imagined how they would plan a future camping trip (future planning task), set either in a familiar (Australia) or an unfamiliar (Antarctica) context. Transcripts were segmented into information units that were coded according to semantic category (e.g., where, when, transport, material, actions). Results revealed a strong interaction between tasks and their presentation order. Starting with the past planning task constrained the future planning task when the context was familiar. Participants generated no new information when the future camping trip was set in Australia and completed second (after the past planning task). Conversely, starting with the future planning task facilitated the past planning task. Participants recalled more information units of their past plan when the past planning task was completed second (after the future planning task). These results shed new light on the role of scripts in past and future thinking and on how past and future thinking processes interact.

Collective memories are memories shared by a group that influence their social identity. The goal of this paper is to focus on two major limitations in current studies on collective memory and show how the hourglass metaphor can overcome those limitations. The first limitation concerns the partial nature of studies devoted to the analysis of collective memory. Studies tend to focus either on the choice of the past (how memory agents mobilise the past) or the weight of the past (how the past affects the individual or the group). The second limitation relates to the temporal dimension of research conducted so far. Most studies only assess memory over a single generation, yet it can have long-term effects. In this paper, we suggest considering memory work as an hourglass, with the collective and the individual at opposite ends and the sand of memories passing from one to the other, filtered through family values and representations. The hourglass metaphor thus provides a helpful tool to explain the formation of collective memories over time and the interactions between the macro, meso, and micro levels. We approach the study of collective memory from an interdisciplinary perspective, mainly involving psychology, political science, and history. We conclude by suggesting three challenges that future studies of memory will need to address: (1) the need to combine multiple approaches; (2) the need to consider the role of generations; and (3) the need to bridge discussion across disciplines.
