在视觉环境不断变化的情况下，由于视觉工作记忆容量的有限性，视觉工作记忆的内容必然是不断变化的。使用变化检测任务，作者表明，VWM是强制性的更新，面对新的信息。当可能改变的项目在记忆编码后1秒和测试前0.5秒被回顾提示时，改变检测性能得到增强。回溯提示的好处不能用记忆衰退或VWM中其他项目的干扰减少来解释。相反，将注意力定向到单个记忆项目使VWM更能抵抗来自测试探针的干扰。作者的结论是，VWM的内容是不稳定的，除非它得到集中注意力，标准的变化检测任务低估了VWM的能力。
Given a changing visual environment, and the limited capacity of visual working memory (VWM), the contents of VWM must be in constant flux. Using a change detection task, the authors show that VWM is subject to obligatory updating in the face of new information. Change detection performance is enhanced when the item that may change is retrospectively cued 1 s after memory encoding and 0.5 s before testing. The retro-cue benefit cannot be explained by memory decay or by a reduction in interference from other items held in VWM. Rather, orienting attention to a single memory item makes VWM more resistant to interference from the test probe. The authors conclude that the content of VWM is volatile unless it receives focused attention, and that the standard change detection task underestimates VWM capacity.
