据称，从快速呈现的集合中提取平均特征是整体的，注意力分布在整个集合中。我们研究了观察者对平均色调的提取是否是整体的，或者是否可以反映子采样。平均色调的选择分析显示，在预期的平均色调达到峰值的分布。然而，一个理想的观察者模拟表明，一个二次抽样机制，包括两个项目，从每个合奏将足以重现大多数观察者的精度。结果表明，色调可能不会像其他属性那样整体和有效地平均。(C)2016美国光学学会
It is claimed that the extraction of average features from rapidly presented ensembles is holistic, with attention distributed across the whole set. We investigated whether observers' extraction of mean hue is holistic or could reflect subsampling. Analysis of selections for the mean hue revealed a distribution that peaked at the expected mean hue. However, an ideal observer simulation suggested that a subsampling mechanism incorporating just two items from each ensemble would suffice to reproduce the precision of most observers. The results imply that hue may not be averaged as holistically and efficiently as other attributes. (C) 2016 Optical Society of America
