The unfavorable comparison between the obtained and expected outcomes of our choices may elicit disappointment. When the comparison is made with the outcome of alternative actions, emotions like regret can serve as a learning signal. Previous work showed that both anticipated disappointment and regret influence decisions. In addition, experienced regret is associated with higher emotional responses than disappointment. Yet it is not clear whether this amplification is due to additive effects of disappointment and regret when the outcomes of alternative actions are available, or whether it reflects the learning feature of regret signals. In this perspective, we used eye‐tracking to measure the visual pattern of information acquisition in a probabilistic lottery task. In the partial feedback condition, only the outcome of the chosen lottery was revealed, while in the complete feedback condition, participants could compare their outcome with that of the non‐chosen lottery, giving them the opportunity to experience regret. During the decision phase, visual patterns of information acquisition were consistent with the assessment of anticipated regret, in addition to a clear assessment of lotteries' expected values. During the feedback phase, subjective ratings and eye‐tracking results confirmed that participants compared their outcome with the outcome of the non‐chosen lottery in the complete feedback condition, particularly after a loss, and ignored the non‐realized outcome of the chosen option. Moreover, participants who made more visual saccades consistent with counterfactual comparisons during the feedback period anticipated regret more in their decisions. These results are consistent with the proposed adaptive function of regret. © 2016 The Authors Journal of Behavioral Decision Making Published by John Wiley & Sons Ltd.  相似文献

Reproductive techniques such as prenatal diagnosis (PND) or preimplantation genetic diagnosis (PGD), although debated, are legally forbidden in France in case of Lynch syndrome. The preference of mutation carriers about their reproductive options is not systematically considered in France. We aimed to prospectively assess the reproductive preferences of mismatch repair mutation carriers consulting in our institution (2003–2010, n?=?100). We also considered the short- and long-term post-disclosure psychological impact using the Impact of Events Scale-Revised questionnaire to measure the prevalence of posttraumatic stress disorder (PTSD) in those patients. Complete data were obtained for 34 respondents (17 males, 17 females, median age of 33.5 years [22–59]). Seventeen respondents (57 %) preferred spontaneous natural conception versus 28 % and 35 % choosing PND and PGD, respectively. At results disclosure, respondents mainly explained their distress by fear of premature death (43 %) and transmitting mutated genes (42 %). One year later, this last fear remained predominant in 55 % of subjects. None of the main socio-demographical, psychological or medical variables (including fear of transmitting mutations) was significantly associated with the reproductive preferences. Results disclosure had a real and time-decreasing psychological impact on mutation carriers. Reproductive techniques, expected to decrease the hereditary risk, were not significantly preferred to natural conception.  相似文献

Our study explored whether the characteristics of pretreatment trauma narratives could be used as indicators of posttraumatic stress disorder (PTSD) symptom severity before treatment. We also studied whether pretreatment characteristics could predict treatment efficacy. Although several studies suggest that fragmentation, proportion of internal events, and length in trauma narratives are associated with PTSD symptomatology, there are contradictions in the findings. Given the differences in trauma response between men and women, we considered the potential influence of gender. Before beginning a cognitive-behavioral therapy treatment, 66 participants verbally recounted their traumatic event during a diagnostic interview. After treatment, 48 participants once again provided a trauma narrative. PTSD symptom severity was assessed using the Clinician-Administered PTSD Scale. Linear regression analyses revealed that none of the pretreatment characteristics predicted treatment efficacy. Furthermore, the length of the trauma narrative was the only pretreatment characteristic that correlated with pretreatment PTSD symptomatology. This suggests that more severe symptomatology is associated with shorter narratives. We only found a significant gender difference in narrative length, which was longer in women than in men. Our findings not only highlight the need for additional research on the link between trauma narratives and PTSD symptomatology, but also stress the necessity of considering gender in this field of research. This could allow for enhanced treatments to target gender-specific needs, thus leading to more individualized care for PTSD patients.  相似文献

It is debatable whether apes can reason about the unobservable properties of tools. We tested orangutans for this ability with a range of tool tasks that they could solve by using observational cues to infer tool functionality. In experiment 1, subjects successfully chose an unbroken tool over a broken one when each tool’s middle section was hidden. This prevented seeing which tool was functional but it could be inferred by noting the tools’ visible ends that were either disjointed (broken tool) or aligned (unbroken tool). We investigated whether success in experiment 1 was best explained by inferential reasoning or by having a preference per se for a hidden tool with an aligned configuration. We conducted a similar task to experiment 1 and included a functional bent tool that could be arranged to have the same disjointed configuration as the broken tool. The results suggested that subjects had a preference per se for the aligned tool by choosing it regardless of whether it was paired with the broken tool or the functional bent tool. However, further experiments with the bent tool task suggested this preference was a result of additional demands of having to attend to and remember the properties of the tools from the beginning of the task. In our last experiment, we removed these task demands and found evidence that subjects could infer the functionality of a broken tool and an unbroken tool that both looked identical at the time of choice.  相似文献

We herein explore the perception of the geographic environment and analyse the mechanisms that constrain the cognitive processing of spatial information in general. Our guiding theoretical background assumption is that the structure of the spatial environment is a cognitively robust and mutually constrained threefold system relating (1) cognitive topology (comprised of a path and place structure of spatial information and constrained by reference frame-based factors), (2) experience-based functional knowledge (including the effects of socio-economic factors, frequency and familiarity) and (3) linguistic representations (primarily encoded in the prepositional system of a natural language). Here, we focus on (2), i.e. the effect of functional knowledge on the process of acquiring spatial knowledge. We empirically tested adolescents aged 12–17 years to explore the interaction between frequency, familiarity and functional knowledge from a developmental point of view. The social factors we explore are precisely defined and parameterized in our results (exposure to a particular urban area, place of residence, gender, age and factors relating to the environmental and social quality of the local area). Our research shows that there are divergences between the so-called objective topology and the cognitive typology of the urban environment that are significantly constrained by intensity of interactions with environment, number of functionally significant places within particular area and age from a developmental perspective in terms of spatial knowledge acquisition.  相似文献

Prolonged stress (≥ six months) may cause a condition which has been named exhaustion disorder (ED) with ICD‐10 code F43.8. ED is characterised by exhaustion, cognitive problems, poor sleep and reduced tolerance to further stress. ED can cause long term disability and depressive symptoms may develop. The aim was to construct and evaluate a self‐rating scale, the Karolinska Exhaustion Disorder Scale (KEDS), for the assessment of ED symptoms. A second aim was to examine the relationship between self‐rated symptoms of ED, depression, and anxiety using KEDS and the Hospital Anxiety and Depression Scale (HAD). Items were selected based on their correspondence to criteria for ED as formulated by the Swedish National Board of Health and Welfare (NBHW), with seven response alternatives in a Likert‐format. Self‐ratings performed by 317 clinically assessed participants were used to analyse the scale's psychometric properties. KEDS consists of nine items with a scale range of 0–54. Receiver operating characteristics analysis demonstrated that a cut‐off score of 19 was accompanied by high sensitivity and specificity (each above 95%) in the discrimination between healthy subjects and patients with ED. Reliability was satisfactory and confirmatory factor analysis revealed that ED, depression and anxiety are best regarded as different phenomena. KEDS may be a useful tool in the assessment of symptoms of Exhaustion Disorder in clinical as well as research settings. There is evidence that the symptom clusters of ED, anxiety and depression, respectively, reflect three different underlying dimensions.  相似文献

This study examined the role of passion for work in the health impairment and motivational processes proposed by the job demands-resources model. Based on the dualistic model of passion, we proposed that harmonious and obsessive passion intervene simultaneously in the relationship between (1) job demands and burnout/engagement, and (2) job resources and burnout/engagement. This model was tested in two occupational samples: nurses (n = 1,179) and teachers (n = 745). Results from structural equation modeling support the proposed model in both samples. That is, both types of passion partially mediated the relationship between job demands and burnout, while harmonious passion partially mediated the relationship between job demands and engagement. Moreover, harmonious passion partially mediated the relationship between job resources and burnout/work engagement. Implications for burnout research and management practices are discussed.  相似文献

This opinion paper takes aim at an error made recently by Clarivate Analytics in which it sent out an email that congratulated academics for becoming exclusive members of academia’s most cited elite, the Highly Cited Researchers (HCRs). However, that email was sent out to an undisclosed number of non-HCRs, who were offered an apology shortly after, through a bulk mail, which tried to down-play the importance of the error, all the while praising the true HCRs. When Clarivate Analytics senior management was contacted, the company declined to offer an indication of the number of academics who had been contacted and erroneously awarded the HCR status. We believe that this regrettable blunder, together with the opacity offered by the company, fortify the corporate attitude about the value of the journal impact factor (JIF), and what it represents, namely a marketing tool that is falsely used to equate citations with quality, worth, or influence. The continued commercialization of metrics such as the JIF is at the heart of their use to assess the “quality” of a researcher, their work, or a journal, and contributes to a great extent to driving scientific activities towards a futile endeavor.  相似文献

Emerging cognitive control supports increasingly adaptive behaviors and predicts life success, while low cognitive control is a major risk factor during childhood. It is therefore essential to understand how it develops. The present study provides evidence for an age‐related shift in the type of information that children prioritize in their environment, from objects that can be directly acted upon to cues signaling how to act. Specifically, gaze patterns recorded while 3‐ to 12‐year‐olds and adults engaged in a cognitive control task showed that whereas younger children fixated on targets that they needed to respond to before gazing at task cues signaling how to respond, older children and adults showed the opposite pattern (which yielded better performance). This shift in information prioritization has important conceptual implications, suggesting that a major force behind cognitive control development may be non‐executive in nature, as well as opening new directions for interventions.  相似文献
