中文摘要：

本研究分别从外显自尊和内隐自尊角度出发，以大学生情绪面孔（高兴，中性，愤怒）图片为实验材料，采用“空间线索任务”实验范式，探讨不同自尊水平个体注意偏向的特点及其内在机制。结果表明，在无效线索条件下，低外显自尊个体对以愤怒为提示线索的靶刺激的反应时显著长于高兴和中性，说明低外显自尊个体对负性情绪信息（愤怒）的注意偏向是一种注意的解脱困难；高内隐自尊个体在无效线索条件下，对以高兴和愤怒为提示线索的靶刺激的反应时显著长于中性，说明高内隐自尊个体更易受到情绪性信息（愤怒和高兴）的吸引，是一种选择性的注意维持倾向，表现为注意的解脱困难。

英文摘要：

There is a wealth of evidence demonstrating attentional bias for negative （angry） stimuli in low self-esteem （LSE） participants, but the components of the bias （vigilance versus difficulty in disengagement） remains unclear. Researchers have demonstrated that individuals with high self-esteem （HSE） were able to successfully engage in negative mood regulation by recruiting positive thoughts and memories to assuage the dysphoria caused by the negative mood manipulation. By contrast, individuals with low self-esteem were either unmotivated or unable to engage in mood regulation and thus were negatively affected by the sad moodmanipulation （MacDonald ＆ Martineau, 2002）. Wood and her colleagues （1990） have shown that negative moods can increase self-focus. For persons with low self-esteem, focusing on the self may prime feelings of general negativity about the self, thereby leading to global negative self-evaluations. Such feelings of inadequacy may be hard to escape. Smith and Petty （1995） have demonstrated that individuals with low self-esteem are less motivated or able than individuals with high self-esteem to engage in cognitive strategies to counteract negative mood states. All these evidences suggested that attentional bias for negative stimuli among individuals with low self-esteem may be derived from difficulty in disengaging attention from negative stimuli. Using a spatial cueing task, we clearly examined the components of attentional bias （vigilance, difficulty in disengagement or both） among low self-esteem participants. In addition, previous studies just examined the modulation of explicit self-esteem on attention, it is still unclear the effects of implicit self-esteem on attention. In present study, there were 67 subjects （32 LSE） in explicit self-esteem group and 74 subjects （36 LSE） in implicit self-esteem group. Rosenberg self-esteem scale and implicit associate test （IAT） were used to test participants＇ explicit and implicit self-esteem level respective
