In this study, I examined emotional modulation of the eyeblink, skin conductance, and cardiac responses to an acoustic startle (103 dB[A] white noise) probe. Twenty-five female and 17 male undergraduates imagined pleasant, neutral, and fearful situations in a tone-cured imagery procedure. Both the eyeblink and skin conductance responses to startle probes were potentiated (larger magnitude, shorter latency) during fear as compared with neutral and pleasant imagery. The amount of emotional modulation in these two response systems was significantly correlated both between and within subjects. The startle probe interrupted ongoing cardiac deceleration during the imagery task, but but this interruption was not related to the emotional content of imagery.
在本研究中，我检测了眨眼、皮肤电传导以及心脏对听觉惊吓刺激（103 dB[A]白噪声）探测的情绪调节。25名女大学生和17名男大学生在一个音频辅助的意象程序中想象愉悦、中性和恐惧的情境。与中性和愉悦意象相比，在恐惧意象期间，对惊吓探测的眨眼和皮肤电传导反应均增强（幅度更大、潜伏期更短）。这两个反应系统中的情绪调节量在受试者之间和受试者内部均显著相关。惊吓探测在意象任务期间打断了正在进行的心脏减速，但这种打断与意象的情绪内容无关。
