人类在日常生活和临床互动中经常提到自己的情绪状态。理论解释表明，当报告我们的情绪时，我们整合了我们经历的历史；然而，这种整合的时间结构仍未得到检验。在这里，我们使用一种计算方法来定量地回答这个问题，并表明与最近的事件相比，早期事件对报告的情绪（首要权重）产生更大的影响。我们表明，与随机、一致或动态奖励环境、不同年龄组以及健康和抑郁参与者的一系列替代时间表征相比，首因模型更能解释情绪报告。此外，我们在与情绪调节相关的额叶脑区域发现了神经编码“先因”而非“后因”模型的证据。这些发现对实验或临床环境中事件的时间安排具有启示意义，并为个性化情绪干预提供了新的方向。
Humans refer to their mood state regularly in day-to-day as well as clinical interactions. Theoretical accounts suggest that when reporting on our mood we integrate over the history of our experiences; yet, the temporal structure of this integration remains unexamined. Here, we use a computational approach to quantitatively answer this question and show that early events exert a stronger influence on reported mood (a primacy weighting) compared to recent events. We show that a Primacy model accounts better for mood reports compared to a range of alternative temporal representations across random, consistent, or dynamic reward environments, different age groups, and in both healthy and depressed participants. Moreover, we find evidence for neural encoding of the Primacy, but not the Recency, model in frontal brain regions related to mood regulation. These findings hold implications for the timing of events in experimental or clinical settings and suggest new directions for individualized mood interventions.
