Emotional intelligence and attentional bias for threat‐related emotion under stress

Emotional intelligence (EI ) can buffer potentially harmful effects of situational and chronic stressors to safeguard psychological wellbeing (e.g., Mikolajczak, Petrides, Coumans & Luminet, 2009 ), yet understanding how and when EI operates to promote adaptation remains a research priority. We explored whether EI (both trait and ability) modulated early attentional processing of threat‐related emotion under conditions of stress. Using a dot probe paradigm, eye movement (fixation to emotive facial stimuli, relative to neutral) and manual reaction time data were collected from 161 adults aged 18–57 years (mean age = 25.24; SD = 8.81) exposed to either a stressful (failure task) or non‐stressful (control) situation. Whilst emotion management ability and trait wellbeing corresponded to avoidance of negative emotion (angry and sad respectively), high trait sociability and emotionality related to a bias for negative emotions. With most effects not restricted to stressful conditions, it is unclear whether EI underscores ‘adaptive’ processing, which carries implications for school‐based social and emotional learning programs.     

拖延刺激对注意偏向的影响及过程

研究是考察拖延个体对拖延相关信息的注意偏向及特点。实验1采用情绪Stroop范式,要求被试忽略刺激的语义,仅判断刺激的颜色。实验2采用修改后的点探测范式,以拖延词和中性词为线索,并操作线索和目标之间的时间间隔,被试的任务是判断目标刺激的位置。结果发现:高拖延的被试难以抵制拖延词的注意,在情绪Stroop任务中对拖延词的反应时间更长; 当拖延词和目标刺激的位置一致时,在短的线索—目标时间间隔(SOA)内,被试对目标刺激的反应时间更长,但当时间间隔长时,一致条件下的反应时更短。该研究表明,高拖延行为个体在有限的时间内难以抵制拖延信息的注意,对拖延刺激存在注意偏向。     

Interference and conflict monitoring in individuals with amnestic mild cognitive impairment: A structural study of the anterior cingulate cortex

Amnestic mild cognitive impairment (aMCI) is a clinical condition characterized by memory impairment in the absence of any other cognitive impairment and is commonly associated with high conversion to Alzheimer's disease. Recent evidence shows that executive functions and selective attention mechanisms could also be impaired in aMCI. In this study, we investigated performance differences (i.e., reaction times [RTs] and accuracy) between a group of aMCI participants and a group of age‐matched healthy individuals on the attentional network task (ANT) focusing on situations with increased interference. In particular, we assessed the relationship between interference and conflict effects and grey matter volumes (GMVs) of the anterior cingulate cortex (ACC)/pre‐supplementary motor area in the entire sample because of its crucial role in conflict monitoring. When compared with controls, aMCI participants were less accurate on the ANT, showing increased interference and conflict effects, but no differences in RTs. In addition, aMCI participants exhibited lower GMV in the ACC than controls. While better accuracy for interference and conflict effects was associated with an increase of GMV in the ACC for both groups, RTs from the interference effect were negatively correlated with GMV of the ACC only in aMCI participants. In other words, lower GMV values of the ACC were paralleled with significantly impaired performance in terms of interference resolution. In conclusion, our study suggests the presence of a selective impairment in interference and conflict monitoring in aMCI, which in turn is associated with decreased GMVs in the ACC.     

Attentional Capture by Emotional Stimuli: Manipulation of Emotional Valence by the Sample Pre‐rating Method

Eye movements directed at emotional and neutral pictures were investigated. Participants were instructed to fixate on a target and avoid looking at a non‐target. Results of trials consisting of emotional and neutral pictures were analyzed based on participants’ evaluations of the stimuli before the experiment. Results indicated that the number and duration of fixations were larger and longer for targets than for non‐targets. Further, the probability of first fixation was less for neutral targets than for emotional targets. This suggests that unpleasant pictures capture visual attention and that the attentional orienting is subject to automatic response. The possibility that top‐down processes of visual attention may be involved in attentional capture was also discussed.     

网络成瘾倾向者对负性表情注意的脱离困难

采用Young编制的IAT量表从382名青少年中筛选出网络成瘾倾向者15名,非网络成瘾控制组被试18名,利用视觉搜索范式比较了两组被试对真人面孔和卡通面孔表情的注意偏向差异。结果表明：（1）在注意快速定向阶段,当要求被试快速准确地从中性面孔矩阵中搜索高兴或者愤怒面孔时,相较于控制组被试,网络成瘾倾向者搜索愤怒面孔更迅速,尤其表现为对卡通愤怒面孔的快速定向优势;（2）在注意的维持和脱离阶段,当在愤怒或高兴面孔矩阵中搜索中性面孔时,相较于控制组被试,网络成瘾倾向者在更具威胁性的真人愤怒面孔矩阵中最难脱离。结论：网络成瘾倾向者具有负性注意偏向特点,表现为对负性表情具有快速定向和解脱困难。且相较于控制组被试,网络成瘾倾向者对卡通面孔注意定向更快而更难从真人愤怒面孔矩阵中脱离,也说明了其注意偏向主要为对负性信息的注意解除困难。     

Set points of positivity ratio for different levels of well‐being: A latent profile analysis

Previous studies have explored the set points of the positivity ratio by grouping according to predetermined cut‐off scores, resulting in inconsistent criteria and unstable results. This study intends to further explore the set points of the positivity ratio using latent profile analysis. Two samples of 716 college students and 381 adults in China completed the Questionnaire for Eudaimonic Well‐Being, the Personal Growth Subscale from Ryff's Psychological Well‐being Scale, the Need Satisfaction Questionnaire, and the Emotional Experience of Well‐Being Questionnaire. College students were classified into four classes (2.0, 2.8, 3.7 and 5.0) with the set points of the positivity ratio, whereas adults were classified into three classes (1.9, 2.9 and 4.2) with the set points of the positivity ratio. The difference of the set points between college students and adults was nonsignificant for medium and high well‐being classes, and significant with a small effect size for the higher well‐being class. Future research should examine more diverse samples and combine the real experience method to further explore the set points of the positivity ratio.     

创伤后应激障碍个体对威胁刺激的注意偏向：眼动研究的证据

对威胁刺激的注意偏向是创伤后应激障碍(PTSD)个体的一种表现。近年来, 研究者利用眼动技术探讨了注意偏向的加工特点及其内在机制。尽管针对是否存在注意定向加速、注意解除困难或注意回避的研究结果并不一致, 但都试图为验证如警戒-回避模型、注意保持模型等提供眼动证据。未来研究在记录PTSD个体注视模式时, 不仅需要从多个维度构建、整合PTSD个体的眼动模型, 也要结合多种技术从多模态角度共同考察PTSD个体的威胁信息注意偏向机制。     

失恋经历对爱情相关刺激注意偏向的影响:趋近还是回避?

为探讨失恋经历对爱情相关刺激注意偏向的影响,采用眼动和事件相关电位技术考察有、无失恋个体在加工积极和消极爱情信息时眼动和ERP特征。通过2个实验结果发现：在总注视时间和注视点个数眼动指标上,图片类型和失恋经历的交互作用达到统计显著水平;有失恋经历被试比无失恋经历被试对消极爱情图片的注视点更多,注视时间更长。积极爱情图片比消极爱情图片诱发的N1波峰更大,有失恋经历被试对积极图片的N1潜伏期显著快于无失恋经历的被试;有失恋经历被试在积极爱情图片上的P1波峰小于无失恋经历被试。研究表明,有、无失恋经历被试对爱情相关刺激的注意偏向存在眼动特征和神经生理上的显著差异：有失恋经历者在行为上对消极爱情图片存在注意趋近偏向,而在神经生理上对积极爱情图片存在注意回避倾向。     

注意瞬脱范式中的知觉负载对情绪面孔加工的影响

情绪性刺激的加工是否受注意影响目前尚存争论。基于许多操纵空间注意焦点的研究未能在注意资源的分配上进行精确的调节, 本实验将时间维度的注意瞬脱范式与负载理论相结合, 通过调节注意瞬脱中T1刺激物知觉负载水平的高低(箭头朝向相同与否), 观察被试在四种时间延迟条件下(延迟2, 延迟3, 延迟5, 延迟8)T2目标侦测任务恐惧和中性面孔的反应正确率, 从而对情绪性刺激的加工特征进行研究。实验发现：对恐惧面孔侦测的正确率在高知觉负载条件下显著降低, 而中性面孔则不受知觉负载水平影响, 并且这种高知觉负载对恐惧面孔加工的抑制作用仅发生在注意瞬脱中的短延迟条件下。说明在知觉加工资源和注意调节作用同时受限的情况下恐惧面孔的优势加工受到限制, 提示情绪性刺激的加工与中性刺激相比消耗的加工资源较少, 并依赖于注意的调控。
