高社交焦虑者识别动态情绪面孔的神经机制

近年来, 大量的研究对高社交焦虑者的情绪面孔加工和社交焦虑的干预进行了考察, 取得了丰富成果, 但仍存在以下不足: (1) 在以往的中国动态情绪面孔库存中, 刺激材料的情绪类别、视频维度以及视频持续时间的种类偏少; (2) 高社交焦虑者识别动态情绪面孔的神经机制未被系统探讨; (3) 注意偏向训练的效果存在争议, 即一些研究者发现注意偏向训练对社交焦虑有明显的缓解作用, 而其他研究者却未发现注意偏向训练的效果。针对这些不足, 当前项目建设的中国人动态情绪面孔库拟增加刺激材料的情绪类别、视频维度以及视频持续时间的类型, 此外运用神经科学的技术系统探究高社交焦虑者对动态情绪面孔的识别机制, 最后采用工作记忆训练改善高社交焦虑者对动态生气面孔识别的注意偏向。本研究团队提出了高社交焦虑个体识别动态情绪面孔的神经机制模型, 该模型主要包括机制和干预两个部分。本项目的开展不仅为动态情绪面孔加工和社交焦虑研究提供了新视角, 还突破原有单一的研究方法, 拟从行为、电生理和脑成像三个层次进行研究。研究成果将促进社交焦虑干预工作的开展, 从而缓解社交焦虑个体的心理健康问题, 对于提高他们的幸福感和生命质量有重要价值。     

阈下抑郁个体对负性情绪刺激的注意解脱困难

本研究拟采用点探测范式及不同情绪内容的面孔刺激（高兴、中性、悲伤和愤怒）考察阈下抑郁个体的负性注意偏向及其内在机制。点探测任务中情绪面孔配对呈现（负性-中性、正性-中性）,配对面孔中的情绪线索位置与靶刺激的位置构成负性一致/不一致和正性一致/不一致条件,同时实验中加入“中性-中性”面孔线索作为一致和不一致条件的对比基线来考察注意偏向的内在机制。结果发现,阈下抑郁个体在负性不一致条件下的反应时显著长于负性一致条件,表明阈下抑郁个体具有对负性刺激的注意偏向;进一步比较发现,阈下抑郁个体在负性不一致条件下的反应时显著的长于“中性-中性”基线条件,而负性一致条件与基线之间差异不显著,表明阈下抑郁个体的负性注意偏向为对负性刺激的注意解脱困难。结果另发现,阈下抑郁个体未能像无抑郁对照组个体表现出对正性刺激的注意偏向。结果表明,处于阈下抑郁状态的个体表现出对负性刺激的注意偏向,具体为对负性刺激的注意解脱困难,其原因可能是由于阈下抑郁个体在注意控制和情绪调节功能上的紊乱。     

Continual training of attentional bias in social anxiety

Using the dot-probe paradigm, it has been shown that high social anxiety is associated with an attentional bias toward negative information. In the present study, individuals with high social anxiety were divided into two groups randomly. One group was the attentional bias training group (Group T), and the other was the control group (Group C). For Group T, 7 days' continuous training of attentional bias was conducted using the dot-probe paradigm to make socially anxious individuals focus more on positive face pictures. The results showed that the training was effective in changing attentional bias in Group T. Scores of the Social Interaction Anxiety Scale (SIAS) in Group T were reduced compared to Group C, while the scores of Social Phobia Scale (SPS) and scores of Negative Evaluation Scale (FNE) showed no difference between the two groups, which suggested a limited reduction of social anxiety.     

Malleability of attentional bias for positive emotional information and anxiety vulnerability

Recent research supports a causal link between attentional bias for negative emotional information and anxiety vulnerability. However, little is known about the role of positive emotional processing in modulating anxiety reactivity to stress. In the current study, we used an attentional training paradigm designed to experimentally manipulate the processing of positive emotional cues. Participants were randomly assigned to complete a computerized probe detection task designed to induce selective processing of positive stimuli or to a sham condition. Following training, participants were exposed to a laboratory stressor (i.e., videotaped speech), and state anxiety and positive affect in response to the stressor were assessed. Results revealed that individual variability in the capacity to develop an attentional bias for positive information following training predicted subsequent emotional responses to the stressor. Moreover, individual differences in social anxiety, but not depression, moderated the effects of the attentional manipulation, such that, higher levels of social anxiety were associated with diminished attentional allocation toward positive cues. The current findings point to the potential value of considering the role of positive emotional processing in anxiety vulnerability.     

Attentional bias to negative information and 5-HTTLPR genotype interactively predict students' emotional reactivity to first university semester

People strongly differ in their emotional reactions to potentially stressing and challenging environmental circumstances. Two classes of individual differences have independently been reported to contribute to such emotional vulnerability: an attentional bias to negative information and a variation in the serotonin transporter gene (5-HTTLPR). The present study was conducted to investigate the possibility that these cognitive and genetic markers interact in their prospective prediction of emotional reactivity to an extended and mild potential stressor. Changes in dysphoria and anxiety across their first university semester were measured in 120 students. Results indicate that attentional bias toward negative information on Week 1 of the semester significantly predicted cross-semester changes in both anxiety and dysphoria. For the latter, this predictive capacity depended on the 5-HTTLPR genotype. Specifically, only in homozygous carriers of the 5-HTTLPR short allele did attentional bias to negative information on Week 1 significantly predict cross-semester change in dysphoria. These results carry important theoretical and practical implications concerning the ability to identify individuals vulnerable to experiencing elevated emotional reactivity to potentially stressing life-events.

Anxiety and Attention: Is There an Attentional Bias for Positive Emotional Stimuli?

Empirical research has shown that anxiety is associated with a systematic bias in the cognitive system. Anxious individuals (clinically anxious patients and normal individuals with high-trait anxiety) are characterized by a pattern of selective processing that favors the encoding of threatening information. Is this attentional bias specific to threat-related information, or does it operate for positive emotional stimuli? The research directly connected with the existence of an attentional bias for threat in anxiety was examined.     

Biased attentional processing of positive stimuli in social anxiety disorder: an eye movement study

Despite the established relationship between social anxiety and attentional bias towards threat, a growing base of evidence suggests that social anxiety is additionally maintained by a deficit in the attentional processing of positive information. However, it remains unclear which component of attention is implicated in this deficit. Using eye movement-based measures and a novel attentional cuing methodology, the present study sought to investigate the presence of anxiety-linked bias in attentional engagement with, attentional disengagement from, and total fixation time to, socially relevant emotional stimuli in individuals diagnosed with social anxiety disorder, relative to non-socially anxious controls. Socially anxious individuals were found to exhibit faster attentional disengagement from positive stimuli, and reduced total fixation time to all emotional stimuli, relative to controls. Additionally for socially anxious individuals, lower total fixation times to positive stimuli were associated with higher levels of state anxiety. No differential pattern of engagement was evident between groups. We conclude that social anxiety is maintained in part by the aberrant processing of positive social stimuli.     

Attentional networks and visuospatial working memory capacity in social anxiety

Social anxiety is associated with attentional bias and working memory for emotional stimuli; however, the ways in which social anxiety affects cognitive functions involving non-emotional stimuli remains unclear. The present study focused on the role of attentional networks (i.e. alerting, orienting, and executive control networks) and visuospatial working memory capacity (WMC) for non-emotional stimuli in the context of social anxiety. One hundred and seventeen undergraduates completed questionnaires on social anxiety. They then performed an attentional network test and a change detection task to measure visuospatial WMC. Orienting network and visuospatial WMC were positively correlated with social anxiety. A multiple regression analysis showed significant positive associations of alerting, orienting, and visuospatial WMC with social anxiety. Alerting, orienting networks, and high visuospatial WMC for non-emotional stimuli may predict degree of social anxiety.
