Psychological resources and flexibility predict resilient mental health trajectories during the French covid-19 lockdown.

The implementation of lockdowns and the Covid-19 pandemic situation have negatively impacted mental health (anxiety, depression). However, little is known about individual differences in the longitudinal reactions to lockdown. We designed a longitudinal study (a) to identify the various trajectories of symptoms of depression and anxiety in the general population during and after lockdown; (b) to determine which positive psychological resources prevent individuals from falling into groups with the most severe trajectories; (c) to test the mediating role of psychological flexibility.

Basic human values during the COVID-19 outbreak, perceived threat and their relationships with compliance with movement restrictions and social distancing.

This study examines the evolution of Schwartz's Basic Human Values during the COVID-19 outbreak, and their relationships with perceived threat, compliance with movement restrictions and social distancing. An online questionnaire was administered to a heterogeneous sample of French citizens (N = 1025) during the first French lockdown related to the outbreak. Results revealed a significant evolution of values; the conservation value was higher during the outbreak than usual, and both self-enhancement and openness-to-change values were lower during the COVID-19 outbreak than usual.

Psychological Resources Protect Well-Being During the COVID-19 Pandemic: A Longitudinal Study During the French Lockdown.

This longitudinal study investigated the capability of various positive psychological resources to directly or indirectly protect specific well-being outcomes and moderate the effects on well-being of health and economic threats in a lockdown situation during the 2020 health crisis in France. At the beginning of lockdown (wave 1), participants ( = ) completed self-assessment questionnaires to document their initial level of well-being and state of nine different well-established psychological resources, measured as traits: optimism, hope, self-efficacy, gratitude toward the world, self-transcendence, wisdom, gratitude of being, peaceful disengagement, and acceptance. Three weeks later, a weekly follow-up was started to record changes in well-being and reported threats for a duration of 5 weeks (waves 2-6).

Using theta and alpha band power to assess cognitive workload in multitasking environments.

Cognitive workload is of central importance in the fields of human factors and ergonomics. A reliable measurement of cognitive workload could allow for improvements in human machine interface designs and increase safety in several domains. At present, numerous studies have used electroencephalography (EEG) to assess cognitive workload, reporting the rise in cognitive workload to be associated with increases in theta band power and decreases in alpha band power.

Differences in Multitask Resource Reallocation After Change in Task Values.

Objective: The objective was to characterize multitask resource reallocation strategies when managing subtasks with various assigned values.

Background: When solving a resource conflict in multitasking, Salvucci and Taatgen predict a globally rational strategy will be followed that favors the most urgent subtask and optimizes global performance. However, Katidioti and Taatgen identified a locally rational strategy that optimizes only a subcomponent of the whole task, leading to detrimental consequences on global performance.

Fuzzy-TLX: using fuzzy integrals for evaluating human mental workload with NASA-Task Load indeX in laboratory and field studies.

Unlabelled: The aim of this study was to assess mental workload in which various load sources must be integrated to derive reliable workload estimates. We report a new algorithm for computing weights from qualitative fuzzy integrals and apply it to the National Aeronautics and Space Administration -Task Load indeX (NASA-TLX) subscales in order to replace the standard pair-wise weighting technique (PWT). In this paper, two empirical studies were reported: (1) In a laboratory experiment, age- and task-related variables were investigated in 53 male volunteers and (2) In a field study, task- and job-related variables were studied on aircrews during 48 commercial flights.

Non-bayesian inference: causal structure trumps correlation.

The study tests the hypothesis that conditional probability judgments can be influenced by causal links between the target event and the evidence even when the statistical relations among variables are held constant. Three experiments varied the causal structure relating three variables and found that (a) the target event was perceived as more probable when it was linked to evidence by a causal chain than when both variables shared a common cause; (b) predictive chains in which evidence is a cause of the hypothesis gave rise to higher judgments than diagnostic chains in which evidence is an effect of the hypothesis; and (c) direct chains gave rise to higher judgments than indirect chains. A Bayesian learning model was applied to our data but failed to explain them.

Politeness and conditional reasoning: interpersonal cues to the indirect suppression of deductive inferences.

A successful theory of conditional reasoning requires an account of how reasoners recognize the pragmatic function a conditional statement is meant to perform. Situations in which it is ambiguous whether a conditional statement was meant to add information or to correct a mistake are discussed in this article. This ambiguity has direct consequences on the way reasoners update their beliefs and derive conclusions.

Utilitarian relevance and face management in the interpretation of ambiguous question/request statements.

Often, requests are made in an indirect manner and phrased in such a way that they can also be construed as questions. For example, the sentence "Is there any coffee left?" can be construed either as a question about coffee or as a request for coffee. This article offers a combined test of some key predictions of two approaches to the disambiguation of question/request statements: (1) the face management approach, which gives a prominent role to variables such as status and potential loss of face; and (2) the utilitarian relevance approach, which gives a prominent role to the goals pursued by the speaker at the time he or she issues the statement.

Determinants of conflict detection: a model of risk judgments in air traffic control.

Objective: A model of conflict judgments in air traffic control (ATC) is proposed.

Background: Three horizontal distances determine risk judgments about conflict between two aircraft: (a) Dt(o) is the distance between the crossing of the aircraft trajectories and the first aircraft to reach that point; (b) Dt(h) is the distance between the two aircraft when they are horizontally closest; and (c) Dt(v) is the horizontal distance between the two aircraft when their growing vertical distance reaches 1000 feet.

Methods: Two experiments tested whether the variables in the model reflect what controllers do.

Processing of normal, inverted, and scrambled faces in a patient with prosopagnosia: behavioural and eye tracking data.

In this study, we addressed the issue of a spared processing of faces in a patient (SB) with severe prosopagnosia. We designed an experiment comprising of two parts. In Part I, normal upright faces were entwined with scrambled faces, while in Part II normal upright faces were mixed with inverted faces, under unlimited time exposure.

Measuring dynamic bipolarity in positive and negative activation.

The dynamic bipolarity of the positive and negative affective activation, measured with the PANAS scales, was studied using a pre-post design with an intervening experiment. The correlations between (a) the initial positive and negative constructs and (b) the respective change scores were estimated, random and systematic error being removed owing to a convenient structural equation modeling technique. Results demonstrated that a moderate perturbation may induce a medium correlation between latent change scores.

Pain rating by patients and physicians: evidence of systematic pain miscalibration.

This study is an investigation of the existence and potential causes of systematic differences between patients and physicians in their assessments of the intensity of patients' pain. In an emergency department in France, patients (N=200) and their physicians (N=48) rated the patients' pain using a visual analog scale, both on arrival and at discharge. Results showed, in confirmation of previous studies, that physicians gave significantly lower ratings than did patients of the patients' pain both on arrival (mean difference -1.

Implicit face perception in a patient with visual agnosia? Evidence from behavioural and eye-tracking analyses.

This paper investigates face perception in a visual agnosic and prosopagnosic patient (SB). Despite very extensive lesions of visual areas, SB remains capable of some visual processing [Brain 125 (2002) 58]. However, in everyday situations SB does not exhibit signs of specific face recognition.
