正负性情绪的自主神经反应及应用

情绪可以唤醒自主神经系统, 伴随有一系列的生理变化。从基础研究的角度来看, 正负性情绪可以诱发心血管系统(如心率、血压、心率变异性)、皮肤电系统(如皮肤电导水平)、呼吸系统(如呼吸阻力、每分通气量)和其他系统(如瞳孔直径、胃肌电等)的活动及其变化。在应用研究方面, 正负性情绪诱发的自主神经反应可以应用在多个领域, 主要包括用户体验中的情绪测量、基于生理信号的人-机情感交互系统的开发, 以及消费者态度和偏好的测查等。对于现有研究结果中存在的分歧, 从被试的个体差异、诱导范式的不一致性和诱导效果的可靠性, 以及刺激材料属性的多样化等方面进行了分析, 指出了未来研究应该注意的问题。

Autonomic Nervous System’s Response in Positive and Negative Emotion and the Applications

Positive and negative emotion can activate the autonomic nervous system with a series of physiological changes. Results from basic research found that several autonomic systems were involved, including the cardiovascular system (e.g., heart rate (HR), blood pressure (BP) and heart rate variability (HRV)), electrodermal response (e.g., skin conductance level (SCL)), respiratory system (e.g., respiratory resistance (Ros), minute ventilation (Vm)) and other system (e.g., pupil diameter and electrogastrogram (EGG)). The patterns of autonomic nervous response associated with certain kind of emotions have many practical applications, such as measurement of emotional state in user experience, development of human- computer affective interaction system based on physiological signals, and detection of consumers’ attitudes and bias. Regarding the divergences in existing studies, the following three reasons were discussed: the heterogeneity of participants, the inconsistency and reliability of various emotion induction methods, the property diversification of experimental stimuli. Furthermore, some suggestions for future research were proposed.
