In this study, we investigated the perception of risk and the worries about COVID-19 infection in both healthcare workers and the general population in Italy. We studied the difference in risk perception in these two groups and how this related to demographic variables and psychological factors such as stress, anxiety, and death anxiety. To this aim, we administered an online questionnaire about COVID-19 together with other questionnaires assessing the psychological condition of participants. First, we found that the exposition to infection risk, due to living area or job, increased the perceived stress and anxiety (i.e., medical staff in North Italy was more stressed and anxious with respect to both medical- and non-medical participants from Center and South Italy). Then, we conducted hierarchical logistic regression models on our data to assess the response odds ratio relatively to each regressor on each dependent variable. We found that health workers reported higher risk perception, level of worry, and knowledge as related to COVID-19 infection compared to the general population. Psychological state, sex, and living area were less related to these factors. Instead, judgments about behaviors and containment rules were more linked to demographics, such as sex. We discussed these results in the light of risk factors for psychological distress and possible interventions to meet the psychological needs of healthcare workers.

The purpose of this study was to investigate the support of attentional and memory processes in controlling a P300-based brain-computer interface (BCI) in people with amyotrophic lateral sclerosis (ALS). Eight people with ALS performed two behavioral tasks: (i) a rapid serial visual presentation (RSVP) task, screening the temporal filtering capacity and the speed of the update of the attentive filter, and (ii) a change detection task, screening the memory capacity and the spatial filtering capacity. The participants were also asked to perform a P300-based BCI spelling task. By using correlation and regression analyses, we found that only the temporal filtering capacity in the RSVP task was a predictor of both the P300-based BCI accuracy and of the amplitude of the P300 elicited performing the BCI task. We concluded that the ability to keep the attentional filter active during the selection of a target influences performance in BCI control.

The present review systematically examines the literature reporting gaze independent interaction modalities in non-invasive brain-computer interfaces (BCIs) for communication. BCIs measure signals related to specific brain activity and translate them into device control signals. This technology can be used to provide users with severe motor disability (e.g. late stage amyotrophic lateral sclerosis (ALS); acquired brain injury) with an assistive device that does not rely on muscular contraction. Most of the studies on BCIs explored mental tasks and paradigms using visual modality. Considering that in ALS patients the oculomotor control can deteriorate and also other potential users could have impaired visual function, tactile and auditory modalities have been investigated over the past years to seek alternative BCI systems which are independent from vision. In addition, various attentional mechanisms, such as covert attention and feature-directed attention, have been investigated to develop gaze independent visual-based BCI paradigms. Three areas of research were considered in the present review: (i) auditory BCIs, (ii) tactile BCIs and (iii) independent visual BCIs. Out of a total of 130 search results, 34 articles were selected on the basis of pre-defined exclusion criteria. Thirteen articles dealt with independent visual BCIs, 15 reported on auditory BCIs and the last six on tactile BCIs, respectively. From the review of the available literature, it can be concluded that a crucial point is represented by the trade-off between BCI systems/paradigms with high accuracy and speed, but highly demanding in terms of attention and memory load, and systems requiring lower cognitive effort but with a limited amount of communicable information. These issues should be considered as priorities to be explored in future studies to meet users' requirements in a real-life scenario.

A successful transition to a lower-emission society may require major changes in the patterns of individual behaviours. Yet, whilst awareness and concern about climate change have increased in recent years among the global population, global greenhouse gases emissions have not ceased to rise. This paper discusses potential reasons underlying the gap between individual knowledge of climate change and the actions implemented to contain greenhouse gas emissions. To investigate this phenomenon, we look at the scientific literature exploring the factors influencing pro-environmental behaviour. First, we highlight how an individual’s environmental knowledge is not only approximate but also biased by cognitive, affective, and cultural factors, influencing their appraisal of climate information and their motivation to act. Second, we discuss three major models of pro-environmental behaviour, such as the Theory of Planned Behaviour (TPB), the Norm-Activation Model (NAM), and the Value-Belief-Norm (VBN), to highlight their failure to account for automatic cognitive and affective factors influencing an individual’s ability to implement pro-environmental intentions. Then, we discuss the Comprehensive-Action-Determination Model of pro-environmental behaviour (CADM), and its efforts to overcome the limits of the previous models. Finally, we examine the dispositional traits associated with pro-environmental engagement to highlight how the relationship between dispositions and pro-environmental behaviour performance appears related to self-regulation processes, supported by executive functioning; increased self-regulation would enable alignment of pro-environmental intentions and behaviours, and anticipation of the long-term consequences of present behaviours. We conclude by calling for more research to be carried out on the effect of enhanced self-regulation, and of self-regulation training, on individual reactions to the climate crisis.

Humor is considered an adaptive coping strategy as it could reduce the burden of perceived stress and increase positive emotional states when dealing with stressful situations. Humor has been reported in several models as a rather independent strategy that can be correlated with both approach-based coping strategies and avoidance-based coping strategies. Humor can be defined as a hedonistic escapism strategy that would work better in the presence of unpredictable or uncontrollable stressors, such as the spread of the COVID-19 pandemic and its related confinement measures. Therefore, during such a stressful event, humor would have increased the positive effect of the approach coping style on mental health and reduced the negative effect of the avoidance coping style. Based on this hypothesis, we conducted a cross-sectional study with a moderation analysis in which we assessed the interaction of humor with both approach-based and avoidance-based coping styles on perceived stress in a large sample of Italian participants collected in April and May 2021. Despite some limitations related to sampling and study design, the results obtained partially support our hypothesis, as we observed that humor had a significant moderating effect on the relationship between avoidance coping and psychological distress, with a reduction of perceived stress while using such a coping style in the presence of a medium to high level of humor. On the other hand, we did not observe a significant moderating effect of humor on the relationship between the approach coping style and perceived stress. In general, our results support the beneficial effect of humor on mental health and highlight a special role for humor as a moderator of other coping strategies.

Great scientific effort has been devoted to understanding what drives pro-environmental behaviour, yet the question of the environmental attitude–behaviour gap remains unanswered. Studies have indicated that self-regulation and executive functions may reduce such a gap by increasing individuals’ ability to maintain attention on present actions and to resist goal-conflicting temptations. Given the inherent association of self-regulation and executive functions with dispositional mindfulness, we carried out a cross-sectional study to test the hypothesis of the role of dispositional mindfulness in explaining the phenomenon. Our results showed that higher levels of dispositional mindfulness, measured via the Five Facets Mindfulness Questionnaire (FFMQ), are related to a higher tendency to perform pro-environmental behaviour, and that the observing facet of the construct would predict higher pro-environmental behaviour scores. Interestingly, we also found the acting with awareness and nonjudging factors to be moderators of the relationship between pro-environmental attitudes and behaviours, suggesting that enhanced awareness of the present moment may favour higher congruence between attitudes and behaviours, and that higher acceptance may favour more adaptive coping strategies to the climate challenge. Our findings provide a novel contribution to the understanding of the relationship between mindfulness and pro-environmental behaviour and support the perspective that self-regulation skills would contribute to reducing the environmental attitude–behaviour gap.
