Humans can estimate their confidence in making correct decisions, but these confidence judgments are biased by their other estimations, an effect known as confidence leak. However, it remains unclear whether this effect arises automatically. Here, we address this issue by having participants make two visual decisions and give confidence ratings for one or for both decisions within each trial. Using the well-known interaction between task difficulty and response accuracy as a proxy for confidence, we found that confidence ratings for one decision were greater when the other decision was also associated with greater confidence, even when the latter was not explicitly rated. For one of the two tasks, this confidence leak also occurred when participants knew in advance that no confidence rating would be required for the other task. Our results support the idea that confidence can be automatically integrated across decisions. (PsycInfo Database Record (c) 2021 APA, all rights reserved).
人类能够估计自己做出正确决策的信心，但这些信心判断会受到他们其他估计的影响，这种效应被称为信心泄漏。然而，目前尚不清楚这种效应是否会自动产生。在这里，我们通过让参与者做出两个视觉决策，并在每个试验中对其中一个或两个决策给出信心评级来解决这个问题。我们使用任务难度和反应准确性之间众所周知的相互作用作为信心的代理指标，发现当另一个决策也与更高的信心相关时，即使后者没有明确评级，对一个决策的信心评级也会更高。对于这两个任务中的一个，当参与者事先知道另一个任务不需要信心评级时也会出现这种信心泄漏。我们的结果支持这样一种观点，即信心可以在决策之间自动整合。（PsycInfo数据库记录（c）2021美国心理学会，保留所有权利）
