人们认为，对个人情感事件（情感意象）的回忆和重新体验会引起中枢神经系统的神经活动，从而影响身体状态的生理机能。有人提出，先前参与情感体验的神经系统越活跃，与该体验相关的身体状态越活跃，情感意象就越生动。交感神经系统（SNS）和胃肠系统（GI）参与情绪反应。在此基础上，我们假设生动的情感意象会伴随着胃肠道和交感神经系统活动的强烈增加。为了检验这一假设，17 名健康参与者对涉及各种情绪状态（快乐、恐惧、厌恶、悲伤、愤怒）的强烈自传记忆进行了情感意象。分别通过皮肤电导和胃电图测量的 SNS 和 GI 变化与图像期间唤醒的主观评分呈正相关。然而，SNS 的变化与情感意象生动度的评分并不相关，更有趣的是，GI 的变化与生动度的评分呈强烈负相关。为了解释这些发现，我们提出，在高度生动的意象体验中，中枢神经系统强烈地模拟整个情感体验，而身体信息起着较小的作用。在低生动意象体验中，中枢神经系统不会非常强烈地模拟情感体验，来自身体（包括胃肠系统）的信息起着更大的作用。这种解释是在理论框架的背景下提出的，它预测了“身体循环”和“仿佛身体循环”之间的这种分离，以体验和重新体验情绪和感觉。
The recall and re-experiencing of a personal emotional event (emotional imagery) are thought to evoke neural activity in the central nervous system that can affect the physiology of bodily states. It has been proposed that the more active the neural systems previously engaged in the emotional experience, and the more active the bodily state associated with that experience, the more vivid the emotional imagery is. The sympathetic nervous system (SNS) and the gastrointestinal system (GI) are engaged in emotional reactions. On this basis, we hypothesized that vivid emotional imagery would be accompanied by strong increases in gastrointestinal and sympathetic nervous system activity. To test this hypothesis, 17 healthy participants performed emotional imagery of strong autobiographical memories involving various emotional states (happy, fear, disgust, sadness, anger). SNS and GI changes, measured by skin conductance and electrogastrogram, respectively, correlated positively with subjective ratings of arousal during the imagery. However, the SNS changes did not correlate with ratings of emotional imagery vividness, and even more intriguingly, the GI changes correlated strongly and negatively with vividness ratings. To account for these findings, we propose that in highly vivid imagery experience, the central nervous system is simulating the whole emotional experience strongly, and bodily information plays a lesser role. In low vivid imagery experience, the central nervous system is not simulating very strongly the emotional experience, and information coming from the body (including the GI system) plays a greater role. This interpretation is set forth in the context of theoretical framework, which predicts such a dissociation between a “body loop” and an “as if body loop” for the experiencing and re-experiencing of emotions and feelings.
