A set of physiological studies proves that conscious perception of affective stimuli influence on respiratory activity. Less is known about the effect of unconscious perception of emotional information on human breathing. The aim of current research is to compare time characteristics of respiration during unconscious and conscious perception of emotional stimuli. As emotionally provocative stimuli we used natural vocalizations of 3-month-old infants in different emotional state. Both ways of acoustic presentation--first-order unconscious and second-order conscious stimuli--were applied to the one subject within one experiment with a brief inter-trial interval. A comparative data analysis revealed significant changes in time characteristics of respiration in response to acoustic emotional stimuli perceived either consciously or unconsciously. The differences in respiratory dynamics during two conditions of emotional stimuli perception are discussed.
一系列生理学研究证明，对情感刺激的有意识感知会影响呼吸活动。关于对情绪信息的无意识感知对人类呼吸的影响，我们了解得较少。当前研究的目的是比较在无意识和有意识感知情绪刺激期间呼吸的时间特征。作为具有情感激发性的刺激，我们使用了处于不同情绪状态的3个月大婴儿的自然发声。在一个实验中，将两种声学呈现方式——一阶无意识刺激和二阶有意识刺激——以较短的试验间隔应用于同一受试者。比较数据分析显示，无论是有意识还是无意识感知到的声学情绪刺激，都会使呼吸的时间特征发生显著变化。文中讨论了在两种情绪刺激感知条件下呼吸动力学的差异。
