Emotions are fundamentally temporal processes that dynamically change over time. This temporal nature is inherently involved in making emotions adaptive by guiding interactions with our environment. Both the size of emotional changes across time (i.e., emotional instability) and the tendency of emotions to persist across time (i.e., autocorrelation of emotional experience, emotional inertia) are key features of a person's emotion dynamics, and have been found central to maladaptive functioning and psychopathology as well as linked to social functioning. However, whether different (neural) mechanisms are underlying these dynamics as well as how they are related to the processing of (socio-) emotional information is to date widely unknown. Using a combination of Experience Sampling methods (ESMs) and fMRI (involving a social feedback paradigm), we examine how emotional instability and inertia in everyday life are associated with different aspects of the neural response to socio-emotional events. The findings indicate that while emotional instability is connected to the response of the core salience network (SN), emotional inertia is associated to responses in the parahippocampal gyrus (PHG) and lateral orbitofrontal cortex (lOFC). This is the first study showing that different aspects of the neural response to socio-emotional events are associated with different aspects of the temporal dynamics of emotion in real life.
情绪从根本上来说是随时间动态变化的过程。这种时间特性在通过引导我们与环境的互动使情绪具有适应性方面起着内在作用。情绪随时间变化的幅度（即情绪不稳定性）以及情绪随时间持续的倾向（即情绪体验的自相关性、情绪惯性）都是一个人情绪动态的关键特征，并且已被发现对于适应不良的功能和精神病理学至关重要，同时也与社会功能相关联。然而，到目前为止，对于这些动态变化背后是否存在不同的（神经）机制以及它们如何与（社会）情感信息的处理相关联，人们还知之甚少。我们结合经验抽样方法（ESMs）和功能磁共振成像（fMRI，涉及社会反馈范式），研究日常生活中的情绪不稳定性和惯性如何与对社会情感事件的神经反应的不同方面相关联。研究结果表明，虽然情绪不稳定性与核心突显网络（SN）的反应有关，但情绪惯性与海马旁回（PHG）和外侧眶额皮质（lOFC）的反应有关。这是第一项表明对社会情感事件的神经反应的不同方面与现实生活中情绪时间动态的不同方面相关联的研究。
