The study investigated whether the cardiac activity and cognitive-emotional traits sustained by the behavioral inhibition/activation system (BIS/BAS) may contribute to hypnotizability-related pain modulation. Nociceptive stimulation (cold-pressor test) was administered to healthy participants with high (highs) and low (lows) hypnotizability in the presence and absence of suggestions for analgesia. Results showed that heart rate increased abruptly at the beginning of nociceptive stimulation in all participants. Then, only in highs heart rate decreased for the entire duration of hand immersion. During stimulation with suggestions of analgesia, pain threshold negatively correlated with heart rate. BIS/BAS activity partially accounted for the observed hypnotizability-related differences in the relation between cardiac interoception and pain experience.
该研究调查了行为抑制/激活系统（BIS/BAS）维持的心脏活动和认知-情绪特征是否有助于与催眠相关的疼痛调节。在存在和不存在镇痛建议的情况下，对高（高）和低（低）催眠易感性的健康参与者进行了伤害性刺激（冷加压试验）。结果表明，在所有参与者中，在伤害性刺激开始时心率突然增加。然后，只有在高催眠易感性的情况下，心率在整个手部浸入过程中才会下降。在镇痛建议的刺激下，疼痛阈值与心率呈负相关。BIS/BAS 活动部分解释了观察到的与催眠相关的心脏内脏感知与疼痛体验之间关系的差异。
