Role of event centrality and emotion regulation in posttraumatic stress disorder symptoms among internally displaced persons

Background: Event centrality and emotion regulation in relation to posttraumatic stress disorder (PTSD) have been documented in various global samples especially in Western cultures; but internally displaced persons (IDPs) still constitute an underrepresented population in psychotraumatology literature. This study tested the roles of event centrality and emotion regulation strategies (cognitive reappraisal and expressive suppression) in PTSD symptoms among IDPs in Nigeria.

Design: The multi-group cross-sectional design was adopted.

Methods: Tiv language versions of the Centrality of Events Scale, Emotion Regulation Questionnaire, and Harvard Trauma Questionnaire were completed by 859 IDPs in two camps located in Benue State, North-central region of Nigeria.

Results: Hierarchical multiple linear regression results indicated that event centrality positively predicted PTSD symptoms. Cognitive reappraisal was a negative predictor of PTSD symptoms while expressive suppression was a positive predictor of PTSD symptoms. Bonferroni corrections indicated that expressive suppression was the strongest predictor of total PTSD symptoms, avoidance/numbing symptoms, and hyper-arousal symptoms; but event centrality was the most robust predictor of PTSD intrusion/re-experiencing symptoms.

Conclusion: The findings underscore recent developments in psychotraumatology indicating that the extent to which individual differences impact the development of PTSD is essential in clinical psychology research and practice.     

The Mediating Role of Resiliency in the Relationship Between Temperament and Posttraumatic Growth

The purpose of the research is to investigate the mediating role of resiliency in the relation between temperamental traits and posttraumatic growth. Data of 74 persons who have experienced the death of someone close were analyzed. The range of age of the participants was 21–74 years (M = 38.4; SD = 15.5). The Posttraumatic Growth Inventory (PTGI), the Formal Characteristics of Behavior–Temperament Inventory (FCB-TI), and the Resiliency Assessment Scale were used in the study. Resiliency plays a mediating role among four traits of temperament (Briskness, Emotional Reactivity, Endurance, and Activity) and posttraumatic growth. Resiliency seems to modify the direct impact of temperamental traits on positive posttraumatic changes.     

An event‐related potential study on the “check operation” in the Eriksen task1

Abstract: We examined two issues for the Eriksen task with two types of stimuli, the central target letter of which was flanked with noise (e.g., HHHHH for compatible stimuli and SSHSS for incompatible stimuli). First, we examined whether or not a response‐stop function is carried out until the check operation to detect and correct erroneous response readiness has finished (Eriksen & Eriksen, 1974). Second, reaction times for incompatible stimuli are not prolonged if only identical noise stimuli are used throughout the block. This phenomenon is called the blocking effect. We then explored whether or not the blocking effect can be caused by the selective inhibition of erroneous response readiness (Eriksen & Schultz, 1979). Sixteen participants (18–29 years old) selectively pressed one of two buttons for the target letter. The results showed that the negative potential related to the response‐stop function was enlarged for incompatible stimuli. Moreover, the blocking effect was observed, while erroneous response readiness was still observable for incompatible stimuli. These results suggest that the blocking effect is caused by something other than reciprocal inhibition.     

创业意向的构思测量、影响因素及理论模型

创业意向是指将创业者的注意力、精力和行为引向某个特定目标的一种心理状态, 它是创业行为的最好预测指标。个人背景、人格特质和外界环境等都会影响创业意向。计划行为理论和创业事件模型是公认的两个创业意向理论框架。目前将创业意向作为因变量是主流研究, 而作为自变量和控制变量则是未来研究趋势。     

心脏病患者非心脏手术风险的规避

社会老龄化,老年人口的相对比例以及绝对值不断增长,外科手术患者中合并心脏病的患者比例也在不断增加。这类患者都具有较高的围手术期心肌梗死、心衰及心源性死亡的危险。如何评价这些患者的围手术期风险,细致调整心脏病用药,使患者获得最佳治疗,保证患者的医疗安全,同时避免术前不必要的检查。     

三字字谜顿悟的时间进程和半球效应：一项ERP研究

运用事件相关电位ERPs技术, 采用猜谜任务范式, 从字谜问题解决中谜底“催化”所诱发顿悟的时间进程和半球差异两方面来探讨顿悟的认知神经机制。结果发现：在320~550ms内, “有顿悟”和“不理解”较“无顿悟”的ERP波形均有一个更大的负向偏移。在“有顿悟-无顿悟”和“不理解-无顿悟”差异波中, 该负成分的潜伏期约为380ms, 差异波的脑电峰值锁定在Cz点。半球主效应不显著, 但反应与半球交互效应显著, 其中“有顿悟”差异波的右半球平均波幅显著高于左半球和矢中部。结果表明：N380可能反映了顿悟中舍弃强外显意义而选择弱内在隐喻意义的认知抉择过程, 且右半球在“顿悟”中表现出优势效应。     

Crimes and Punishments

Every criminal act ought to be matched by a corresponding punishment, or so we may suppose, and every punishment ought to reflect a criminal act. We know how to count punishments. But how do we count crimes? In particular, how does our notion of a criminal action depend on whether the prohibited action is an activity, an accomplishment, an achievement, or a state?     

情绪对连续事件定向遗忘的影响

本研究采用项目法定向遗忘范式以中性和负性连续事件的视频为实验材料, 通过2个实验考察了情绪对连续事件定向遗忘的影响, 并进一步探讨了情绪对细节记忆和要义记忆的定向遗忘的影响。结果发现, 情绪可以消除细节记忆的定向遗忘效应, 而仅有要义记忆的定向遗忘效应则主要受到事件连续性而非情绪的影响。
