我们通过检查次级记忆任务如何干扰记忆引导扫视的准确性来研究工作记忆过程的组织。在一个随机位置闪现一个目标，后面跟着一个汉字。受试者必须记住目标和汉字的位置，然后他们必须向记住的目标位置进行扫视。显示第二个汉字，受试者必须决定它是相同的还是不同的。7名非汉字阅读者与6名流利的汉字阅读者在任务中的表现进行了比较。研究发现，汉字的记忆会干扰非汉字读者的记忆引导扫视的准确性，而汉字读者则不会。这些发现直接反驳了工作记忆功能的说法，即空间和视觉对象记忆在功能上是分离的。
We investigated the organisation of working memory processes by examining how a secondary memory task interferes with the accuracy of memory-guided saccades. A target was flashed at a random location, followed by a Kanji character. Subjects had to remember the location of the target and the Kanji character, and then they had to make a saccade towards the remembered target location. A second Kanji character was displayed and the subject had to decide if it was same or different. The performance of seven non-Kanji reader's were compared with six fluent Kanji readers in the task. Memorisation of Kanji characters was found to interfere with the accuracy of memory-guided saccades made by non-Kanji, but not by Kanji readers. These findings directly contradict accounts of working memory function which propose that spatial and visual object memory are functionally discrete.
