我们测试了全局和局部场景信息获取的 3 种理论，根据空间频率定义全局和局部。根据独立理论，高频和低频空间频率信息在同一时间过程中获取并相加地组合。根据全局优先理论，全局信息获取先于局部信息获取，但它们相加地结合在一起。根据交互理论，全局信息也会影响局部信息的获取率。我们报告了 2 个数字回忆实验。第一，我们确认了独立理论。第二，我们否定了独立理论和互动理论。将全球优先理论作为剩下的选择。我们证明了特定的全局优先理论定量地解释了实验 1-2 的数据以及过去的数据。我们讨论了他们的空间尺度的空间频率定义如何与其他人使用的定义相一致，并且我们考虑了 P. G. Schyns 及其同事（例如，D. J. Morrison & Schyns，2001）的建议，即视觉系统在使用空间尺度时可以灵活地而不是僵化地行动。
We test 3 theories of global and local scene information acquisition, defining global and local in terms of spatial frequencies. By independence theories, high- and low-spatial-frequency information are acquired over the same time course and combine additively. By global-precedence theories, global information acquisition precedes local information acquisition, but they combine additively. By interactive theories, global information also affects local-information acquisition rate. We report 2 digit-recall experiments. In the 1st, we confirmed independence theories. In the 2nd, we disconfirmed both independence theories and interactive theories. leaving global-precedence theories as the remaining alternative. We show that a specific global-precedence theory quantitatively accounted for Experiments 1-2 data as well as for past data. We discuss how their spatial-frequency definition of spatial scale comports with definitions used by others, and we consider the suggestion by P. G. Schyns and colleagues (e.g., D. J. Morrison & Schyns, 2001) that the visual system may act flexibly rather than rigidly in its use of spatial scales.
