自主神经系统活动是情感体验的重要组成部分。我们在恒河猴身上证明，自主神经系统的交感和副交感神经分支对被动观看的视频刺激的情感价位做出不同的反应。当成年猕猴观看一系列300个30秒的视频时，我们记录了心阻抗和心电图，这些视频的情感内容各不相同。我们发现，随着视频内容从正值变为负值，交感神经活动(由心脏射血前期来衡量)增加，而副交感神经活动(由呼吸性窦性心律失常来衡量)减少。这些发现与人类自主神经系统反应性和刺激价之间的关系是平行的。鉴于人类心脏生理学和情感加工之间的关系，这些发现表明猕猴的心脏生理学可能是非语言动物的情感指数。
Autonomic nervous system activity is an important component of affective experience. We demonstrate in the rhesus monkey that both the sympathetic and parasympathetic branches of the autonomic nervous system respond differentially to the affective valence of passively viewed video stimuli. We recorded cardiac impedance and an electrocardiogram while adult macaques watched a series of 300 30-second videos that varied in their affective content. We found that sympathetic activity (as measured by cardiac pre-ejection period) increased and parasympathetic activity (as measured by respiratory sinus arrhythmia) decreased as video content changes from positive to negative. These findings parallel the relationship between autonomic nervous system responsivity and valence of stimuli in humans. Given the relationship between human cardiac physiology and affective processing, these findings suggest that macaque cardiac physiology may be an index of affect in nonverbal animals.
