Positive anticipatory experiences are key to daily well-being. However, the brain's functional architecture underlying real-world positive anticipatory experiences and well-being remains unexplored. In the present study, we combined an ecological momentary assessment and resting-state functional neuroimaging to identify the neural predictors of real-world positive anticipatory experiences and explore their relationships with subjective well-being (SWB). With a model-based approach, we quantified participants' accuracy in predicting positive events and the degree to which participants' affective states were influenced by the positive anticipation. We found that individuals with higher accuracy in predicting upcoming positive events showed greater SWB, and this relationship was mediated by greater positive anticipatory feelings. Importantly, functional connectivity of the dorsal and ventral striatal-hippocampal networks significantly predicted the accuracy and positive anticipatory feelings, respectively. These functional networks were further predictive of SWB. Our findings provide novel and ecologically valid evidence that the interaction between neural systems for reward-processing and memory plays an important role in real-life positive anticipatory experiences and everyday SWB.
积极的预期体验是日常幸福感的关键。然而，现实世界中积极预期体验和幸福感背后的大脑功能结构仍未被探索。在本研究中，我们结合了生态瞬时评估和静息态功能神经成像，以确定现实世界中积极预期体验的神经预测指标，并探索它们与主观幸福感（SWB）的关系。通过基于模型的方法，我们量化了参与者预测积极事件的准确性以及参与者的情感状态受积极预期影响的程度。我们发现，在预测即将到来的积极事件方面准确性较高的个体表现出更高的主观幸福感，并且这种关系由更强烈的积极预期感受介导。重要的是，背侧和腹侧纹状体 - 海马网络的功能连接分别显著预测了准确性和积极预期感受。这些功能网络进一步预测了主观幸福感。我们的研究结果提供了新颖且具有生态效度的证据，表明奖励处理和记忆的神经系统之间的相互作用在现实生活中的积极预期体验和日常主观幸福感中起着重要作用。
