视觉工作记忆是否受到对象数量、对象内与任务相关的属性或属性之间的绑定的限制，这一问题一直存在争议。然而，这场辩论受到了一些限制，包括使用不同研究之间的条件，以及缺乏适当的数学模型来估计不同刺激条件下工作记忆中的项目数量。我们在两个实验中重新研究了工作记忆极限，实验条件涉及颜色和形状属性，依赖于一组新的模型来适应各种刺激情况。在实验2中，一个新的程序允许相同的检索条件在不同的条件下的注意编码。结果表明，多个属性竞争注意，但保留属性之间的绑定是通过保留属性本身来完成的。我们提出了一个理论帐户，其中一个固定的对象容量限制包含在它的对象属性的不完全保留的可能性，这取决于注意力的方向。
It has been debated on the basis of change-detection procedures whether visual working memory is limited by the number of objects, task-relevant attributes within those objects, or bindings between attributes. This debate, however, has been hampered by several limitations, including the use of conditions that vary between studies and the absence of appropriate mathematical models to estimate the number of items in working memory in different stimulus conditions. We re-examined working memory limits in two experiments with a wide array of conditions involving color and shape attributes, relying on a set of new models to fit various stimulus situations. In Experiment 2, a new procedure allowed identical retrieval conditions across different conditions of attention at encoding. The results show that multiple attributes compete for attention, but that retaining the binding between attributes is accomplished only by retaining the attributes themselves. We propose a theoretical account in which a fixed object capacity limit contains within it the possibility of the incomplete retention of object attributes, depending on the direction of attention.
