Four lexical decision experiments are reported that use the masked priming paradigm to study the role of letter position information in orthographic processing. In Experiments 1 and 2, superset primes, formed by repetition of 1 or 2 letters of the target (e.g., jusstice-JUSTICE) or by insertion of 1 or 2 unrelated letters (e.g., juastice-JUSTICE), generated significant priming compared with unrelated primes and did not differ significantly from an identity priming condition. In Experiment 3, identity primes generated significantly faster responses than subset primes formed by removal of 2 letters from the target (e.g., jutie-JUSTICE), and subset primes generated faster responses than substitution primes formed by substitution of 2 letters of the target with unrelated letters (e.g., jumlice-JUSTICE). In Experiment 4, insertion of 3 unrelated letters continued to generate facilitation relative to unrelated primes but significantly less so than the identity prime condition. The authors discuss the implications of these results for letter-position coding schemes.
本文报告了四项词汇判断实验，这些实验采用掩蔽启动范式来研究字母位置信息在正字法加工中的作用。在实验1和实验2中，通过重复目标词的1个或2个字母（如jusstice - JUSTICE）或插入1个或2个无关字母（如juastice - JUSTICE）形成的超集启动词，与无关启动词相比产生了显著的启动效应，且与完全相同的启动条件相比无显著差异。在实验3中，完全相同的启动词产生的反应速度明显快于通过从目标词中删除2个字母形成的子集启动词（如jutie - JUSTICE），而子集启动词产生的反应速度快于通过用无关字母替换目标词的2个字母形成的替换启动词（如jumlice - JUSTICE）。在实验4中，插入3个无关字母相对于无关启动词仍产生促进作用，但明显小于完全相同的启动词条件。作者讨论了这些结果对字母位置编码方案的意义。
