In this paper, a revised Pandemonium-like model of visual-feature processing is formulated and a preliminary test of its feasibility is reported. The model differentiates visual-feature processing into a series of hierarchical stages organized by increasing complexity, with the output of each stage going both to the next higher stage, and directly to a more central processor. In the experiment, subjects sorted decks of cards into piles according to the presence or absence of a target stimulus which differed from nontargets in a variety of different features; detection of a feature was sufficient for detection of a target. The data generally supported the revised Pandemonium model, in that targets which differed from nontargets in features thought to be low in the hierarchy were processed faster than targets whose difference was in a high level feature. An extension of the revised model did somewhat less well in predicting the results of sorting for targets in which detection of any one of several features was sufficient for target detection.
本文提出了一种经过修订的类似“群魔殿”的视觉特征处理模型，并报告了对其可行性的初步测试。该模型将视觉特征处理划分为一系列按复杂度递增组织的层次阶段，每个阶段的输出既传至下一个更高阶段，又直接传至一个更核心的处理器。在实验中，受试者根据目标刺激的有无将一叠卡片分成几堆，目标刺激在各种不同特征上与非目标刺激不同；检测到一个特征就足以检测到目标。数据总体上支持修订后的“群魔殿”模型，即与非目标在被认为处于层次结构较低位置的特征上不同的目标，其处理速度比差异在于高层次特征的目标更快。修订模型的一个扩展在预测对其中检测到几个特征中的任何一个就足以进行目标检测的目标进行分类的结果时，表现稍差。
