所有现实世界的物体都是平等的吗？视觉搜索难度随着目标数量的增加而增加，并且随着目标相关视觉工作记忆（VWM）负荷的增加而增加。我们的目标是调查在搜索的背景下，在VWM中保存的单个现实世界对象所施加的负载。视觉杂乱的度量试图量化场景背景下的真实世界集合大小。我们应用这些措施之一，原型对象的数量，个别现实世界的对象，并使用对侧延迟活动（CDA）来衡量由此产生的VWM负载。目前的研究提出了一个现实世界的对象作为目标线索，其次是一个延迟的CDA测量。然后是一个四对象搜索数组。我们比较了CDA和后来的搜索性能从目标线索包含一个高或低数量的原型对象。高原型对象目标线索导致更大的CDA，更长的搜索RT，目标停留时间，并减少搜索指导，相对于低原型对象目标。这些发现表明，具有更多原型对象的目标导致更高的VWM负载和降低的搜索性能。这表明包含在单个对象中的原型对象的数量在VWM中产生类似集合大小的效果，并表明原型对象可能是现实世界VWM负载的可行测量单位。重要的是，这表明并非所有现实世界的对象都是平等的。
Are all real-world objects created equal? Visual search difficulty increases with the number of targets and as target-related visual working memory (VWM) load increases. Our goal was to investigate the load imposed by individual real-world objects held in VWM in the context of search. Measures of visual clutter attempt to quantify real-world set-size in the context of scenes. We applied one of these measures, the number of proto-objects, to individual real-world objects and used contralateral delay activity (CDA) to measure the resulting VWM load. The current study presented a real-world object as a target cue, followed by a delay where CDA was measured. This was followed by a four-object search array. We compared CDA and later search performance from target cues containing a high or low number of proto-objects. High proto-object target cues resulted in greater CDA, longer search RTs, target dwell times, and reduced search guidance, relative to low proto-object targets. These findings demonstrate that targets with more proto-objects result in a higher VWM load and reduced search performance. This shows that the number of proto-objects contained within individual objects produce set-size like effects in VWM and suggests proto-objects may be a viable unit of measure of real-world VWM load. Importantly, this demonstrates that not all real-world objects are created equal.
