Myczek和Simons(2008)已经证明，归因于知觉处理的统计模式的结果可以通过集中注意力只关注几个项目的样本来解释。一些新的发现对这一说法提出了质疑。(1)在给定需要不同集中注意策略的条件下，随机混合条件下的受试者的表现并不比被阻断时更差。(2)在给出小样本时，参与者在估计平均尺寸方面明显比给整个展示时差得多。(3)事实上，没有使用一种貌似合理的建议策略--比较每个显示器中最大的项目，而不是平均大小。对一组相似刺激的分布式关注，使得统计处理模式能够提供对这些现象和其他现象的连贯描述。
Myczek and Simons (2008) have shown that findings attributed to a statistical mode of perceptual processing can, instead, be explained by focused attention to samples of just a few items. Some new findings raise questions about this claim. (1) Participants, given conditions that would require different focused attention strategies, did no worse when the conditions were randomly mixed than when they were blocked. (2) Participants were significantly worse at estimating the mean size when given small samples than when given the whole display. (3) One plausible suggested strategy-comparing the largest item in each display, rather than the mean size-was not, in fact, used. Distributed attention to sets of similar stimuli, enabling a statistical-processing mode, provides a coherent account of these and other phenomena.
