While most people have had the experience of seeing a representation in the mind's eye, it is an open question whether we have control over the vividness of these representations. The present study explored this issue by using an imagery-perception interface whereby color imagery was used to prime congruent color targets in visual search. In Experiments 1a and 1b, participants were required to report the vividness of an imagined representation after generating it, and in Experiment 2, participants were directed to create an imagined representation with particular vividness prior to generating it. The analyses revealed that the magnitude of the imagery congruency effect increased with both reported and directed vividness. The findings here strongly support the notion that participants have metacognitive awareness of the mind's eye and willful control over the vividness of its representations.
虽然大多数人都有过在脑海中看到表象的经历，但我们是否能够控制这些表象的生动程度仍然是一个悬而未决的问题。本研究通过使用意象知觉界面来探讨这个问题，该界面使用颜色意象来为视觉搜索中的一致颜色目标提供提示。在实验 1a 和 1b 中，要求参与者在生成想象的表象后报告其生动程度，而在实验 2 中，要求参与者在生成之前以特定的生动程度来创建想象的表象。分析表明，意象一致性效应的大小随着报告的和定向的生动程度的增加而增加。这些发现强烈支持了这样一种观点，即参与者对头脑中的表象有元认知意识，并可以有意地控制其表象的生动程度。
