Personality disorder assessments are time-intensive and require trained interviewers. They are unlikely to be performed on a routine basis. In clinical and general populations, there is a requirement for short and robust self-administered screening tests for personality disorders. We first translated the original form of the SAPAS into French and validated it in a clinical sample (n=28). This adaptation revealed properties similar to those of the original version. The first and second studies validated the adaptation of the SA-SAPAS as a self-administered questionnaire in clinical (n=45) and general (n=186) populations. We were able to use the same cut-off (score ≥ 2) in both the clinical and general populations and this permitted correct identification in 89% of the clinical subjects (sensitivity of 97.3%; specificity of 50%) and 86% in the general population (sensitivity of 87.5%; specificity of 85.7%). These results suggest possible applications for researchers and clinicians, either as a routine screening test or as a selection tool in both general and clinical populations.
In cases of impending natural disasters, most events are uncertain and emotionally relevant, both critical factors for decision-making. Moreover, for exposed individuals, the sensitivity to the framing of the consequences (gain or loss) and the moral judgments they have to perform (e.g., evacuate or help an injured person) constitute two central effects that have never been examined in the same context of decision-making. In a framed decision-making task with moral dilemma, we investigated whether uncertainty (i.e., unpredictably of events) and a threatening context would influence the framing effect (actions framed in loss are avoided in comparison to the ones framed in gain) and the personal intention effect (unintentional actions are more morally acceptable in comparison to intentional actions) on the perceived moral acceptability of taking action. Considering the impact of uncertainty and fear on the processes underlying these effects, we assumed that these emotions would lead to the negation of the two effects. Our results indicate that the exposure to uncertain events leads to the negation of the framing effect, but does not influence the moral acceptability and the effect of personal intention. We discuss our results in the light of dual-process models (i.e. systematic vs. heuristic), appraisal theories, and neurocognitive aspects. These elements highlight the importance of providing solutions to cope with uncertainty, both for scientists and local populations exposed to natural hazards.
International audienceSeveral factors, such as emotion and uncertainty of the outcome, influence decision-making. We assessed decision-making during a risky event (natural hazard, focusing here on two types of volcanic threats) by manipulating the certainty of lethal threat in an information campaign. We hypothesized that the reduction of uncertainty of lethal threat in an information campaign would improve behavior through more suitable choices by reducing the use of emotional choices. In the scenario that occurred in a familiar place, participants who received information with uncertainty of lethal threat presented more emotional and comfortable choices, such as staying at home, rather than detached ones, such as leaving the area. These were either appropriate (for volcanic ash cloud) or inappropriate (for pyroclastic flow). The certainty hypothesis was partially validated, as certainty influenced the quality of choice in the scenarios that took place at home. Furthermore, participants in the volcanic disaster context presented less suitable decisions compared to those in the neutral context, which was discussed in terms of the presence of emotions, such as fear of volcanic eruption. Our results highlight the importance of controlling the comforting emotional aspect of the home environment in any information communication
Given the growing demand for studies dealing with natural disasters, the research fields of emotion and social cognition require validated picture stimuli of natural hazards. Such material is essential for studying perceptual processes and behaviors of exposed individuals, and it could find practical applications, such as the improvement of communication strategies during crises. We present the Natural Disasters Picture System (NDPS), a database of pictures of natural hazards, with an emphasis on volcanic threats, and their impact on the environment and humans. We first describe in detail the picture selection and database creation. We then report the validation procedure. One hundred twenty participants rated the pictures on the basis of four dimensions: valence, arousal, dominance and certainty. For each picture, we ultimately determined the best-fitting emotion on the basis of its dimensional pattern. The Hierarchical Ascendant Classification, which yielded 4 clusters subdivided into 9 classes, indicated a highly consistent and distinctive classification of the pictures. Overall, 90% of the pictures elicited negative emotions (fear or sadness), and the other 10% induced neutral to positive emotions (e.g., aesthetic emotions). The NDPS offers a new tool for studying natural events and disasters in the field of affective and cognitive sciences, which will benefit from scientific research and its practical applications. The NDPS is unrestrictedly accessible for researchers.
This study investigated a new direction for improving the decision making of populations at risk in the context of uncertain environmental events, such as volcanic hazards. According to the risk as feelings theory and dual process models, situations with certain outcomes do not necessarily require the use of affect heuristics (e.g., experienced feelings, anticipated emotions) as valid information in the decision‐making process. In the case of difficult decisions with moral dilemmas, certainty could even improve decisions. Thus, using an ecological design with various scenarios depicting upcoming volcanic hazards, we examined whether reducing the uncertainty of lethal threat by conveying certainty in an information campaign could influence decision making and promote a better quality of choice (correct application of the recommendations from the competent authorities). We focused specifically on two populations composed of local people living in the vicinity of an active volcano (Tungurahua volcano, Ecuador) and local scientists. We also examined whether a difficult decision involving a moral dilemma (e.g., leaving people behind so as not to jeopardize one's own life) potentiated this effect, compared to a less difficult situation without a dilemma. We demonstrated that, for local people facing a moral dilemma (difficult decision), the reduction of uncertainty of lethal threat involved a better application of the actual recommendations. These outcomes provided perspectives on improving the applications of the recommendations among local populations at risk in the context of a real risk exposure.
The facial width-to-height ratio (fWHR) is a perceptual cue that affects the perception of psychological traits such as dominance. The current research examined whether the fWHR would impact the perception of dominance and emotional intensity when expressing emotions. In study one, we examined whether the emotional facial expressions (EFEs) modify the visually perceivable fWHR by following a specific pattern reflecting the perception of dominance associated with basic EFEs. We found that EFEs differed from neutral poses following the expected pattern: high dominance EFEs (anger, disgust, happiness) increased the fWHR, whereas low dominance EFEs (fear, sadness, surprise) decreased the fWHR. In study two, we investigated whether manipulating the fWHR (low, average, high) would affect the perception of dominance and emotional intensity. We obtained that the fWHR influenced the perception of dominance and emotional intensity but its effect on dominance was only present with high dominance EFEs. One social implication of this effect is that individuals for which expressing dominant emotions lead to high increase of their fWHR would be perceived highly dominant. We discuss that such effect could participate in the development of individuals' dominance and further researches are still needed to determine its social impact in interaction with other factors.
