惊吓反射，面部肌电图（EMG），和自主神经系统的反应进行了检查，在不同的情感价和唤醒的图像。受试者（N= 48）在音调提示的8-strials期间想象情感情景。在负电压条件下，惊吓眨眼幅度大于正电压条件下，高唤醒条件下的惊吓眨眼幅度大于低唤醒条件下的惊吓眨眼幅度。最大的心率加速和最快和最大的皮肤电导反应惊吓探头发生在高唤醒图像。在高唤醒图像期间，颧骨和眼轮匝肌面部肌肉活动较高，而在低唤醒图像期间，皱眉肌活动较高。颧骨和皱眉肌的活动也随情绪效价的变化而变化。惊吓和面部肌电图反应是最吝啬的组织的负面影响（NA）和积极影响（PA）的尺寸，分别。这个NA/PA框架整合了以前的研究，情绪行为的维度理论和病理情绪的生理评估。
The startle reflex, facial electromyogram (EMG), and autonomic nervous system responses were examined during imagery varying in affective valence and arousal. Subjects (N= 48) imagined affective situations during tone‐cued 8‐strials. Startle blink magnitudes were larger and latencies faster during negatively valent than during positively valent conditions and during high‐arousal than during low‐arousal conditions. Greatest heart rate acceleration and fastest and largest skin conductance responses to startle probes occurred during high‐arousal imagery. Zygomatic and orbicularis oculi facial muscle activities were higher during high‐arousal imagery, whereas corrugator muscle activity was higher during low‐arousal imagery. Zygomatic and corrugator activity also varied with emotional valence. The startle and facial EMG responses are most parsimoniously organized by the negative affect (NA) and positive affect (PA) dimensions, respectively. This NA/PA framework integrates previous research, dimensional theories of emotional behavior, and physiological assessment of pathological emotion.
