The aim of this study was to assess psychophysiological affect correlates, in addition to the usual self-report in borderline personality disorder (BPD) compared with avoidant personality disorder (APD) and normal controls (NCs), when responding to standardized experimental stimuli. In 24 BPD female patients, 23 APD female patients, and 27 female NCs, skin conductance response (SCR), heart rate (HR) change, and startle response were recorded while the subjects viewed slides with emotional content. Neither the self-report nor the psychophysiological data supported the hypothesis that affective responses of BPD individuals are generally stronger than those with APD. BPD patients showed no potentiation of the affective modulation of the startle reflex and their electrodermal reactivity was lower than in either the APD subjects or the NCs. The hypothesis of a general affective hyperresponsivity could not be confirmed. Low somatic arousal in BPD can interfere with the anticipation of signal stimuli and may explain the exaggerated openness borderline personalities show to stimuli, particularly in interpersonal situations.
本研究的目的是评估边缘型人格障碍（BPD）患者在对标准化实验刺激做出反应时，除了通常的自我报告外，与回避型人格障碍（APD）患者和正常对照组（NCs）相比的心理生理情感相关性。在24名BPD女性患者、23名APD女性患者和27名女性NCs中，当受试者观看带有情感内容的幻灯片时，记录皮肤电反应（SCR）、心率（HR）变化和惊吓反应。自我报告和心理生理数据均不支持BPD个体的情感反应通常比APD个体更强的假设。BPD患者的惊吓反射情感调制无增强，其皮肤电反应性低于APD受试者或NCs。普遍情感反应过度的假设无法得到证实。BPD患者较低的躯体唤醒可能会干扰对信号刺激的预期，这可能解释了边缘型人格对刺激表现出的过度开放性，尤其是在人际情境中。
