Emotional reactions in women with psychopathy were examined in a mixed-picture paradigm using psychophysiological measures. Startle probes were presented at 2.0 or 4.5 s following onset of a 6-s picture presentation. At 2.0 s, nonpsychopaths exhibited the typical pattern of eyeblink reflex magnitude: unpleasant > neutral > pleasant. Psychopaths with high general levels of anxiety also exhibited this pattern. Psychopaths with lower anxiety exhibited attenuated reflex magnitudes during unpleasant pictures. Similarly, when focusing on psychopathy components, only individuals expressing high antisocial behavior and high emotional detachment exhibited smaller reflex magnitudes during unpleasant pictures. At 4.5 s, all groups exhibited normal, potentiated reflex magnitudes during unpleasant pictures. Group differences were not observed for other measures.
在一个混合图片范式中，使用心理生理学测量方法对患有精神病态的女性的情绪反应进行了研究。在6秒图片呈现开始后2.0秒或4.5秒时呈现惊吓探针。在2.0秒时，非精神病态者表现出典型的眨眼反射幅度模式：不愉快>中性>愉快。具有较高总体焦虑水平的精神病态者也表现出这种模式。焦虑水平较低的精神病态者在观看不愉快图片时反射幅度减弱。同样，当关注精神病态成分时，只有表现出高反社会行为和高情绪超脱的个体在观看不愉快图片时反射幅度较小。在4.5秒时，所有组在观看不愉快图片时都表现出正常的、增强了的反射幅度。在其他测量中未观察到组间差异。
