In uncertain environments, seeking information about alternative choice options is essential for adaptive learning and decision-making. However, information seeking is usually confounded with changes-of-mind about the reliability of the preferred option. Here, we exploited the fact that information seeking requires control over which option to sample to isolate its behavioral and neurophysiological signatures. We found that changes-of-mind occurring with control require more evidence against the current option, are associated with reduced confidence, but are nevertheless more likely to be confirmed on the next decision. Multimodal neurophysiological recordings showed that these changes-of-mind are preceded by stronger activation of the dorsal attention network in magnetoencephalography, and followed by increased pupil-linked arousal during the presentation of decision outcomes. Together, these findings indicate that information seeking increases the saliency of evidence perceived as the direct consequence of one's own actions.
在不确定的环境中，寻求关于替代选择选项的信息对于适应性学习和决策至关重要。然而，信息寻求通常与对首选选项可靠性的改变相混淆。在这里，我们利用了信息寻求需要控制采样哪个选项的事实来分离其行为和神经生理学特征。我们发现，与控制相关的改变想法需要更多的证据来否定当前选项，与信心降低有关，但在下一个决策中仍然更有可能得到证实。多模态神经生理学记录显示，这些改变想法在磁脑电图中背侧注意网络的激活更强之前发生，并在决策结果呈现期间伴随着瞳孔相关唤醒的增加。总的来说，这些发现表明，信息寻求增加了被视为自身行为直接后果的证据的显著性。
