A body of work has developed over the last 20 years that explores facial emotion perception in Borderline Personality Disorder (BPD). We identified 25 behavioural and functional imaging studies that tested facial emotion processing differences between patients with BPD and healthy controls through a database literature search. Despite methodological differences there is consistent evidence supporting a negative response bias to neutral and ambiguous facial expressions in patients. Findings for negative emotions are mixed with evidence from individual studies of an enhanced sensitivity to fearful expressions and impaired facial emotion recognition of disgust, while meta-analysis revealed no significant recognition impairments between BPD and healthy controls for any negative emotion. Mentalizing studies indicate that BPD patients are accurate at attributing mental states to complex social stimuli. Functional neuroimaging data suggest that the underlying neural substrate involves hyperactivation in the amygdala to affective facial stimuli, and altered activation in the anterior cingulate, inferior frontal gyrus and the superior temporal sulcus particularly during social emotion processing tasks. Future studies must address methodological inconsistencies, particularly variations in patients’ key clinical characteristics and in the testing paradigms deployed.  相似文献

Adaptive decision making relies on learning from feedback. Because feedback sometimes can be misleading, optimal learning requires that knowledge about the feedback’s reliability be utilized to adjust feedback processing. Although previous research has shown that feedback reliability indeed influences feedback processing, the underlying mechanisms through which this is accomplished remain unclear. Here we propose that feedback processing is adjusted by the adaptive, top-down valuation of feedback. We assume that unreliable feedback is devalued relative to reliable feedback, thus reducing the reward prediction errors that underlie feedback-related brain activity and learning. A crucial prediction of this account is that the effects of feedback reliability are susceptible to contrast effects. That is, the effects of feedback reliability should be enhanced when both reliable and unreliable feedback are experienced within the same context, as compared to when only one level of feedback reliability is experienced. To evaluate this prediction, we measured the event-related potentials elicited by feedback in two experiments in which feedback reliability was varied either within or between blocks. We found that the fronto-central valence effect, a correlate of reward prediction errors during reinforcement learning, was reduced for unreliable feedback. But this result was obtained only when feedback reliability was varied within blocks, thus indicating a contrast effect. This suggests that the adaptive valuation of feedback is one mechanism underlying the effects of feedback reliability on feedback processing.  相似文献

Our study sought to characterize mood disordered suicide ideators and attempters 50 years and older admitted to a psychiatric ward either for a recent suicide attempt or for ongoing suicidal ideation. We enrolled 50 patients with suicide ideation consecutively admitted to an inpatient department and 50 patients admitted for a suicide attempt made in the last 48 hours. Suicide attempters more frequently had low social support and an age of onset of mood disorder of 46 years and older, and less frequently had a history of suicidal behaviors in the family members and pharmacological treatment, despite the fact that the groups did not differ with regard to antidepressants prescribed. The groups were not distinguishable based on several variables assumed to be risk factors for suicide behavior, such as proximal life events and stressors or alcohol use disorders. In both samples, comorbidity with organic diseases, the presence of stressful life events in the past 12 months, and a diagnosis of major depression were frequently reported. In conclusion, the presence of low social support and the absence of a pharmacotherapy may increase suicidal behaviors in patients at risk.  相似文献

Suicide attempters who met criteria for borderline personality disorder (BPD) comorbid with major depressive disorder (MDD) were compared to both suicide attempters suffering from MDD alone and to attempters with comorbid MDD and other personality disorders (PD). Participants were 239 (158 patients with comorbid PD and 81 patients with MDD without comorbidity) inpatients consecutively admitted after a suicide attempt made in the last 24 hours. Suicide attempters with comorbid MDD and BPD had more frequent previous suicide attempts and were more likely to have a history of aggressive behaviors and alcohol and drug use disorders compared with patients suffering from MDD without Axis II comorbidity.  相似文献

Risk‐taking is a critical health factor as it plays a key role in several diseases and is related to a number of health risk factors. The aim of the present study is to investigate the role of alexithymia in predicting risk preferences across decision domains. One hundred and thirteen participants filled out an alexithymia scale (Toronto Alexithymia Scale—TAS‐20), impulsivity and venturesomeness measures (I7 scale), and—1 month later—the Cognitive Appraisal of Risky Events (CARE questionnaire). The hierarchical regression analyses showed that alexithymia positively predicted risk preferences in two domains: aggressive/illegal behaviour and irresponsible academic/work behaviour. The results also highlighted a significant association of the alexithymia facet, externally oriented thinking (EOT), with risky sexual activities. EOT also significantly predicted aggressive/illegal behaviour and irresponsible academic/work behaviour. The alexithymia facet, Difficulty Identifying Feelings, significantly predicted irresponsible academic/work behaviour. The results of the present study provide interesting insights into the connection between alexithymia and risk preferences across different decision domains. Implications for future studies and applied interventions are discussed.  相似文献

Background/Objective: Depression, anxiety, fatigue, and sleep problems are typical conditions reported in people with multiple sclerosis (MS), often resulting in a reduction of their quality of life (QOL) and well-being. Mindfulness is a multifaceted and complex construct that has been increasingly explored for its correlated to well-being. Despite preliminary evidence, longitudinal data about the impact of mindfulness on QOL in MS remain limited. In addition, Langerian mindfulness, one of the prominent approaches to mindfulness, is yet unexplored in this field. The study aims to examine the longitudinal relationships between two forms of mindfulness (Langerian and contemplative) and QOL, anxiety, depression, fatigue, and sleep. Method: Within a larger randomized controlled trial of an online mindfulness-based stress reduction intervention, a cohort of 156 people with MS was recruited and assessed for both mindfulness constructs, QOL, anxiety, depression, fatigue, and sleep problems. Assessments were repeated after 2 and after another 6 months. Results: Both mindfulness constructs were highly correlated with all investigated outcomes. Both Langerian and contemplative mindfulness predicted higher QOL, lower anxiety, depression, fatigue, and sleep, over time. Conclusions: In both approaches dispositional mindfulness is a protective factor against depression, anxiety, fatigue, and sleep in people with MS.  相似文献

This study addresses the following: (1) does a team leader change along with the quality of the team’s human capital affect post-change team performance?; (2) is functional leadership of the team’s human capital a driver of post-change team performance?; and (3) should interim vs. permanent leaders manage the team’s human capital differently? We analyzed archival data from Major League Baseball teams who had undergone an in-season manager change (N = 129). Team performance improved after a leader change, and the quality of the team’s strategic and non-strategic core human capital were positively related to post-change performance. New leaders who engaged in more active functional leadership of the strategic core human capital enhanced the positive effects of human capital quality. Additionally, active functional leadership enhanced the positive effects of strategic core human capital for interim replacement leaders, but not for permanent replacement leaders. This study extends theory and practice on the importance of functional team leadership and human capital following a leader transition. As such, our results provide actionable knowledge for organizations and managers who are part of leadership transitions. This empirical study leverages a unique sample to provide insights into the implications of team leader transitions. The results of this study shed light on the impact that leader transitions which involve “interim” and “permanent” replacements may have on post-transition team performance and how these different types of leaders should leverage the inherent human capital that exists within the team.  相似文献
