目的:探究高边缘性人格障碍(Borderline Personality Disorder,BPD)特质者的自我-重要他人表征特征.方法:采用自我参照范式.实验一对比28名高BPD特质者与26名低BPD特质者的自我与重要他人参照任务成绩,实验二对比29名有情绪唤起与29名无情绪唤起的高BPD特质者的自我与重要他人参照任务成绩.结果:实验一发现高BPD特质组的自我参照再认成绩显著低于低BPD特质组;高BPD特质组的自我与重要他人参照再认成绩无显著差异.实验二发现高BPD特质者中,有情绪唤起组的自我参照再认成绩显著低于无情绪唤起组,有情绪唤起组的重要他人参照再认成绩显著高于无情绪唤起组.结论:高BPD特质者自我感相对低,自我概念受到重要他人影响,且情绪唤起会增加二者的严重程度.“,”Objective:To investigate the pathology of the self-significant other representation in individuals with high BPD trait.Methods:The Self-Reference Task was induced to the present 2 studies.In study 1,the recognition performance of 28 high BPD trait participants and 26 low BPD trait participants under self and significant reference task were compared.And in study 2,the recognition performance of 29 high BPD trait participants with emotional arousal and 29 high BPD trait participants without emotional arousal were compared.Results:In study 1,the recognition performance of high BPD trait group under self reference task was worse than that of individuals in low BPD trait group(0.27±0.05vs.0.33±0.03,P＜0.05).In study 2,the recognition performance of high BPD trait participants with emotional arousal in self reference task was worse than that of high BPD trait participants without emotional arousal(0.25±0.04 vs.0.28±0.03,P＜0.05).And the recognition performance of high BPD trait participants under significant-other reference condition was better than that of self reference condition(0.33±0.03 vs.0.25±0.04,P＜0.05).Conclusion:The core feature of identity disturbance reflects abnormal self-other representations:lower sense of self and self-concept are affected by significant others.And emotional arousal may enhance the disturbance.
