我们评估的处理能力，建立统计摘要表示（SSR）的平均尺寸在视觉显示使用的顺序方法。四个集群的刺激，每一个由几个不同直径的圆圈，周围的注视。观察者搜索具有最大或最小平均大小的聚类。在同时条件下，所有四个集群同时出现;在顺序条件下，集群一次出现两个。我们发现，多个合奏SSR的处理能力是极端的固定速率瓶颈过程（实验1）。对照实验证实，这不是由于必须比较多次平均处理的结果而引起的（实验2）。在不同的合奏计算SSR，计算SSR为一个单一的合奏使用相同的刺激是一致的无限容量的处理（实验3）。与现有的权利要求相反，对于单个集合而不是多个集合中的项目，似乎是独立提取的摘要表示。一个发展中的理解能力的限制，在知觉处理进行了讨论。
We assessed the processing capacity of establishing statistical summary representations (SSRs) of mean size in visual displays using the simultaneous-sequential method. Four clusters of stimuli, each composed of several circles with various diameters, were presented around fixation. Observers searched for the cluster with the largest or smallest mean size. In the simultaneous condition, all four clusters were presented concurrently; in the sequential condition, the clusters appeared two at a time. We found that the processing capacity of SSRs for multiple ensembles was as extreme as a fixed-rate bottleneck process (Experiment 1). A control experiment confirmed that this was not caused by having to compare the results of multiple averaging processes (Experiment 2). In contrast to computing SSRs across ensembles, computing SSRs for a single ensemble using the same stimuli was consistent with unlimited-capacity processing (Experiment 3). Contrary to existing claims, summary representations appear to be extracted independently for items within single ensembles but not multiple ensembles. A developing understanding of capacity limitations in perceptual processing is discussed.
