摘要
很多使用点探测范式的实验研究证实了高焦虑个体对负性情绪有注意偏向,其中包括特质焦虑、状态焦虑和社会焦虑等。本研究的主要研究目的是探究社会焦虑是否对负性情绪信息有注意偏向以及其认知机制。负性评价恐惧是指个体在受到他人负性评价时感到悲伤和不安,它可以作为衡量社会焦虑的一个指标。因此本研究用修正过的简明负性评价恐惧量表来筛选实验被试,总分的前25%为低分组,即为正常参照组,后25%为高分组,即为社会焦虑组。我们用改良过的点探测范式分别记录了高社会焦虑组(15人)和低社会焦虑组(15人)被试的行为数据和相应的ERP数据。在实验中,我们选了五种表情图片,分别是中性、高兴、恐惧、厌恶和愤怒,组成情绪面孔图片对作为线索刺激呈现在屏幕的左侧和右侧,分别为中性—高兴、中性—恐惧、中性—厌恶和中性—愤怒,图片消失200ms后在其中一个位置上呈现一个目标刺激,被试对目标刺激进行反应,判断目标刺激的方向是向上还是向下。我们主要分析了情绪面孔线索刺激出现时ERP成分P1、P2和N170和目标反应时的P1成分。结果发现高焦虑组对应愤怒情绪面孔表情的P1、P2和N170成分升高,当目标刺激出现在情绪面孔出现过的位置时相应的P1波更高,表明高焦虑个体更容易对威胁性刺激产生早期的注意警觉而且对其存在注意的解除困难,并对情绪性刺激保持持续注意。
A lot of experimental studies using the dot-probe paradigm demonstrated that highly anxious individuals have attentional bias towards negative emotions, including trait anxiety, state anxiety and social anxiety. The main purpose of this study is to explore whether social anxiety has an attentional bias toward negative emotional information and its cognitive mechanism. Negative evaluation of fear is the degree to which individuals experience sadness and apprehension to be negatively evaluated, it can be used as an indicator of social anxiety. Therefore this study used brief fear of negative evaluation to select experimental subjects from a sample of university students, total score in the top 25% for low FNE is a normal reference group, 25% for high score group is high FNE group.We recorded the behavioral data and the corresponding ERP data of the high social anxiety group(15 people) and the low social anxiety group(15 subjects) with the modified dot- probe paradigm. In the experiment, we chose five facial pictures of different individuals, each posing neutrality, happiness, fear, disgust and anger. There were four different types of face pairs: neutral–angry, neutral–happy, neutral–disgust and neutral–fear. After pairs of faces disappear 200 ms there was a neutral target which replaced the emotional face or neutral ones to be judged whether the direction is up or down. We mainly analyzed the P1,P2 and N170 component of ERP in response to pairs of faces and P1 in response to targets. Results showed that anxious individuals were characterized by increased P1,P2 and N170 in response to neutral-angry faces. When target stimuli appeared following the emotional faces, the P1 in response to target was enhanced. These results suggested that highly anxious individuals appear more easily to an early hypervigilance to threatening face stimuli,they are also difficult in disengaging from threat.Highly social anxious individuals keep sustained attention to emotional stimuli.
