The Japanese kana syllabary has 2 allographic forms, hiragana and katakana. As with other allographic variants like the uppercase and lowercase letters of the Roman alphabet, they show robust form-independent priming effects in the allograph match task (e.g., Kinoshita, Schubert, & Verdonschot, 2019), suggesting that they share abstract character-level representations. In direct contradiction, Perea, Nakayama, and Lupker (2017) argued that hiragana and katakana do not share character-level representations, based on their finding of reduced priming with identity prime containing a mix of hiragana and katakana (the mixed-kana prime) relative to the all-katakana identity prime in a lexical-decision task with loanword targets written in katakana. Here we sought to reconcile these seemingly contradictory claims, using mixed-kana, hiragana, and katakana primes in lexical decision. The mixed-kana prime and hiragana prime produced priming effects that are indistinguishable, and both were reduced in size relative to the priming effect produced by the katakana identity prime. Furthermore, this pattern was unchanged when the target was presented in hiragana. The findings are interpreted in terms of the assumption that the katakana format is specified in the orthographic representation of loanwords in Japanese readers. Implications of the account for the universality across writing systems is discussed. (PsycINFO Database Record (c) 2019 APA, all rights reserved).
日语假名有两种异体形式，平假名和片假名。与其他异体变体（如罗马字母的大写和小写字母）一样，它们在同形匹配任务中表现出强大的形式独立启动效应（例如，Kinoshita、Schubert 和 Verdonschot，2019），这表明它们共享抽象的字符级别表示。与这一观点直接矛盾的是，Perea、Nakayama 和 Lupker（2017）基于他们在词汇判断任务中发现的身份启动中混合了平假名和片假名的混合假名启动相对于全片假名身份启动的启动减少的结果，认为平假名和片假名不共享字符级别的表示，目标是用片假名书写的外来词。在这里，我们试图使用混合假名、平假名和片假名启动来调和这些看似矛盾的说法。混合假名启动和平假名启动产生的启动效应是不可区分的，与片假名身份启动产生的启动效应相比，这两种启动效应都减小了。此外，当目标以平假名呈现时，这种模式保持不变。研究结果是基于这样一种假设，即片假名格式在日语读者的外来词的正字法表示中指定。该解释对跨书写系统的普遍性的影响进行了讨论。（PsycINFO 数据库记录（c）2019 APA，保留所有权利）。
