四个实验要求参与者在旋转后跟踪(即更新)1、2、3、4、6、8、10或15个目标对象的位置。在所有情况下，更新不受设置大小的影响。虽然在某些条件下观察到了一些传统的集合大小效应(即，延迟随着内存负载的线性增加)，但这些效应与更新过程无关。数据和参与者战略的模式不符合将空间更新作为一个在线过程的普遍看法。相反，作者得出的结论是，参与者在学习时形成了持久的、长期的布局记忆表征，用于根据需要重建关于布局的空间信息(即，离线更新)。这些结果支持M.Amorim，S.Glasauer，K.Corpinot和A.Berthoz(1997)的包括在线和离线更新的空间更新的两系统模型。
Four experiments required participants to keep track of the locations of (i.e., update) 1, 2, 3, 4, 6, 8, 10, or 15 target objects after rotating. Across all conditions, updating was unaffected by set size. Although some traditional set size effects (i.e., a linear increase of latency with memory load) were observed under some conditions, these effects were independent of the updating process. Patterns of data and participant strategies were inconsistent with the common view of spatial updating as an online process. Instead, the authors concluded that participants formed enduring, long-term memory representations of the layouts at learning that were used to reconstruct spatial information about the layouts as needed (i.e., offline updating). These results support M. Amorim, S. Glasauer, K. Corpinot, and A. Berthoz's (1997) 2-system model of spatial updating that includes both online and offline updating.
