How does a person make decisions across perceptual boundaries? Here, we test the account that confidence constitutes a common currency for perceptual decisions even in childhood by examining whether confidence can be compared across distinct perceptual dimensions. We conducted a strict test of domain-generality in confidence reasoning by asking 6- to 7-year-olds to compare their confidence in 2 decisions, either from the same perceptual dimension (e.g., number vs. number) or from two different perceptual dimensions (e.g., area vs. emotion). Not only could children compare their confidence across and within domains but there were no differences in their abilities to make within- and across-domain comparisons. Our findings support the idea that confidence is represented in a common format even in childhood, which could provide an account for perceptual integration in childhood that doesn't necessitate the use of language.

孩子们灵活地比较他们在感知领域内和跨感知领域的信心。

一个人如何跨越知觉界限做出决定？在这里，我们通过检查信心是否可以跨不同的感知维度进行比较，来测试信心构成了感知决策的通用货币，即使在童年时期也是如此。我们通过要求 6 到 7 岁的孩子比较他们对 2 个决定的信心，或者来自相同的感知维度（例如，数字与数字）或来自两个不同的感知维度，对置信推理的领域普遍性进行了严格的测试（例如，区域与情绪）。孩子们不仅可以跨领域和跨领域比较他们的信心，而且他们进行领域内和跨领域比较的能力也没有差异。我们的研究结果支持这样一种观点，即即使在童年时期，信心也以一种常见的形式表现出来，这可以为不需要使用语言的童年时期的知觉整合提供一个解释。（PsycInfo 数据库记录 (c) 2020 APA，保留所有权利）。
