视觉工作记忆（VWM）的功能和它们的绑定分别进行了探索。当探针保持与原始显示相同的结合时，特征被更好地识别，但是改变位置总体上几乎没有影响。然而，有很强的相互作用的位置与绑定和匹配或新的功能，这表明，当对象出席，功能和位置自发地集成在VWM。尽管如此，当位置改变时，特征也可以以很小的减量被访问，也许是从单独的特征图。另一方面，绑定更容易受到位置变化的影响，这表明位置在绑定对象的早期维护和检索以及它们的初始编码中起着核心作用，至少在言语编码被阻止时是如此。这些结果证明了过去关于VWM中位置和对象分离的说法。
Visual working memory (VWM) was explored separately for features and for their binding. Features were better recognized when the probes retained the same binding as in the original display, but changing the locations had little effect overall. However, there were strong interactions of location with binding and with matching or new features, suggesting that, when objects are attended, features and locations are spontaneously integrated in VWM. Despite this, when the locations are changed, features can also be accessed with little decrement, perhaps from separate feature maps. Bindings, on the other hand, are more vulnerable to location changes, suggesting that locations play a central role in the early maintenance and retrieval of bound objects as well as in their initial encoding, at least when verbal coding is prevented. The results qualify past claims about the separation of locations and objects in VWM.
