Childhood abuse and/or neglect adversely influences development of neurocognitive systems that regulate affect and behavior. Poor inhibitory control over emotional reactions is thus one potential pathway from maltreatment to suicide. Adult psychiatric inpatients completed the Childhood Trauma Questionnaire and an emotional stop-signal task indexing negative emotional action termination (NEAT): the ability to inhibit ongoing motor reactions to aversive stimuli triggered by negative affect. Clinical interviews assessed suicidal thoughts and behaviors during hospitalization (n = 131) and at follow-up assessments 6 months later (n = 87). Our primary aim was to examine whether maltreatment history and NEAT explain overlapping variance in suicidal behaviors (1) retrospectively and (2) 6 months following hospital discharge. Contrary to prediction, childhood maltreatment was unrelated to history of suicidal behaviors. However, NEAT was consistently associated with prior suicidal acts, even controlling for suicidal ideation and demographic covariates. NEAT similarly contributed to the prediction of post-discharge suicidal behaviors, whereas we found no effect of maltreatment history. The present study suggests that NEAT captures suicide risk independently of childhood maltreatment. Results implicated NEAT impairment specifically, rather than broader response inhibition deficits (e.g., to positive stimuli), in past and future suicidal behaviors. These findings provide preliminary support for NEAT as a behavioral vulnerability marker for suicide, with implications for understanding links between maltreatment history and suicidal acts. 相似文献

Due to mood-congruency effects, we expect the emotion perceived on a face to be biased towards one's own mood. But the findings in the scant literature on such mood effects in normal healthy populations have not consistently and adequately supported this expectation. Employing effective mood manipulation techniques that ensured that the intended mood was sustained throughout the perception task, we explored mood-congruent intensity and recognition accuracy biases in emotion perception. Using realistic face stimuli with expressive cues of happiness and sadness, we demonstrated that happy, neutral and ambiguous expressions were perceived more positively in the positive than in the negative mood. The mood-congruency effect decreased with the degree of perceived negativity in the expression. Also, males were more affected by the mood-congruency effect in intensity perception than females. We suggest that the greater salience and better processing of negative stimuli and the superior cognitive ability of females in emotion perception are responsible for these observations. We found no evidence for mood-congruency effect in the recognition accuracy of emotions and suggest with supporting evidence that past reports of this effect may be attributed to response bias driven by mood. 相似文献

负性人际交往经历和负性社会事件是抑郁症的重要诱导因素, 而社会功能受损是抑郁症患者的重要特征之一, 患者通常表现出对社会疼痛的情绪失调。为了提高抑郁症患者在负性社交情境中或面对负性社会事件时的情绪调节能力, 本研究采用经颅磁刺激技术(transcranial magnetic stimulation, TMS), 考察抑郁症患者在腹外侧前额叶(the ventrolateral prefrontal cortex, VLPFC)被激活后其情绪调节能力的改变。结果表明, 当右侧VLPFC被TMS激活且患者采用认知重评策略调节情绪时, 实验组患者(n = 64)比对照组患者(n = 63)在社会排斥情境下报告了更弱的负性情绪体验, 这说明激活右侧VLPFC可以有效提高患者对社会疼痛的外显性情绪调节能力。本研究是采用TMS提高抑郁症患者情绪调节能力的首次尝试, 实验发现不但支持了VLPFC与认知重评策略的因果关系, 还为临床改善抑郁症等社会功能障碍患者的情绪调节能力提供了明确的神经治疗靶点。后续研究还需探讨多疗程TMS刺激方案、改变社会疼痛的诱发方式、对比左右侧VLPFC的治疗效果、尝试使用其他的情绪调节策略, 进一步验证本研究的结论, 优化TMS治疗方案。 相似文献

幼儿对不同的情绪面孔图片存在不同的注意偏向,考察情绪效价与面孔类型对幼儿无意视盲的影响,可以帮助我们进一步认识幼儿对情绪面孔的注意偏向。本研究采用静态无意视盲的实验范式,通过2(面孔类型:符号化卡通、真人)×2(情绪效价:积极、消极)被试间完全随机设计,考察了111名幼儿(62.5±3.6个月,男生60名)在无意注意条件下对不同情绪效价和不同类型面孔的觉察情况。结果表明:(1)幼儿对积极情绪面孔的觉察率显著高于消极情绪面孔;(2)符号化卡通面孔与真人面孔的整体觉察率不存在显著差异;(3)积极情绪面孔中符号化卡通面孔的觉察率高于真人面孔。综上,情绪效价对无意视盲的影响会基于面孔类型的不同而不同,幼儿对卡通积极情绪面孔有更显著的注意偏向。 相似文献

Emerging adults are at substantial risk for developing or worsening psychopathology and university students appear to be particularly vulnerable. Interventions targeted at these young adults that can mitigate transdiagnostic causal risk factors or burgeoning mental health problems have the potential to make a large impact. We aimed to develop and pilot test an accessible, single-session, transdiagnostic group intervention with the goals of enhancing emotion regulation skills and reducing risk for mental health problems in graduate students. The intervention included psychoeducation, skills instruction (e.g., mindful emotion awareness, cognitive flexibility, countering emotion-driven behaviors), group discussion, and supervised practice based on content from the Unified Protocol for Transdiagnostic Treatment of Emotional Disorders. The pilot program demonstrated strong feasibility and acceptability. Baseline, 1-month, and 3-month follow-up surveys also suggested benefits for reducing emotional avoidance and suppression, increasing use of cognitive reappraisal, and reducing symptoms of depression and neuroticism. Graduate students have seldom been the beneficiaries of university-based intervention and prevention research. Furthermore, most college and university mental health centers do not have the capacity to provide psychoeducation, preventative, or early intervention services to the many students who need or could benefit from them. Results suggest that future iterations of this intervention could address such barriers to meaningfully supporting emerging adults in graduate school. 相似文献

日益复杂多变的市场竞争环境对组织的灵活性和适应性都提出了更高的要求, 员工的组织公民行为在这一背景下显得尤为重要, 因它能有效提高组织在不确定环境下的生存能力和核心竞争力、提升组织的绩效水平。虽然已有大量研究关注员工的组织公民行为, 但研究者多采用相对静态的研究范式, 而忽视了组织公民行为的长期动态变化趋势。基于组织社会化视角, 本研究重点关注新员工和工作变更员工组织公民行为的长期动态变化趋势、探索影响组织公民行为动态变化趋势的内在机制和边界条件, 以期为培养和激发员工持续性高水平的组织公民行为提供可参考的理论依据。 相似文献
