摘要
通过对不同情绪唤醒状态下的心率变异性(HRV)和呼吸性窦性心率不齐(RSA)分析,探讨了积极情绪加速高唤醒消极情绪引起的心血管反应向基线恢复的自主神经活动机制。实验表明:与在观看高唤醒恐惧影片结束后观看悲伤影片和中性视频比较,观看高唤醒恐惧影片结束后观看快乐影片加速了高唤醒恐惧影片引起的心率、指脉等心血管反应向基线的恢复;与在观看高唤醒恐惧影片结束后观看悲伤视频和中性视频材料比较,观看高唤醒恐惧影片结束观看快乐影片后的恢复期,被试的迷走神经激活水平迅速增强,迷走神经激活水平甚至超过基线期。积极情绪加速高唤醒消极情绪刺激引起的心血管反应向基线恢复,其自主神经活动机制是在积极情绪状态下个体的交感神经激活迅速降低、迷走神经激活迅速增强。
