对比了字母、位置编码的五种理论：位置特定时隙编码、WickelCoding、开放二元组编码(离散和连续)和空间编码。这些理论对三种不同类型的字母串的相对相似性做出了不同的预测：替换邻居、一次移除的邻居和双重替换邻居。在实验1中，我们使用了虚幻词范式，发现邻居一次移除相似语境导致的虚幻词报告比替换邻居少，但比双重替换邻居多。在实验2和实验3中，我们使用了掩蔽式启动技术和词汇判断任务。易化模式与空间编码所预测的一样，但与时隙编码、WickelCoding和两种版本的开放二元组编码不兼容。这些结果进一步支持了视觉单词识别的SOLAR(自组织词汇获取和识别)模型。
Five theories of how letter,position is coded are contrasted: position-specific slot-coding, Wickelcoding, open-bigram coding (discrete and continuous), and spatial coding. These theories make different predictions regarding the relative similanity of three different types of pairs of letter strings: substitution neighbors, neighbors-once-removed, and double-substitution neighbors. In Experiment 1, we used an illusory word paradigm and found that neighbor-once-removed similarity contexts resulted in fewer illusory word reports than substitution neighbors but more illusory words than double-substitution neighbors. In Experiments 2 and 3, we used a masked form priming technique with a lexical-decision task. The pattern of facilitation was as predicted by spatial coding but was incompatible with slot-coding, Wickelcoding, and both versions of open-bigram coding. These results provide further support for the SOLAR (self-organizing lexical aquisition and recognition) model of visual word identification.
