Cross-linguistic research indicates that the initial unit used to build an ortho-phonological representation can vary between languages and is related to the particular characteristics of the language. Thai is particularly interesting as it has both syllabic and phonemic characteristics. Using the masked priming paradigm, we examined the functional unit that is initially activated when naming monosyllabic Thai words (Experiment 1) and pseudowords (Experiment 2). In Experiment 1, the response times to the onset prime and identity (onset + vowel) conditions were not significantly different but were both significantly faster than the control prime (onset different). In Experiment 2, pseudowords were used so that the effects of orthographic vowel position could be examined. In Thai, vowels can precede the consonant in writing but phonologically follow it in speech (e.g., the written word 'odg' would be spoken as /dog/) whereas other vowels are spoken in the order that they are written. Similar results were found as in Experiment 1, as the identity prime did not have a greater facilitatory effect than the onset consonant prime. Notably, there were no orthographic effects due to orthographic vowel position. These results support the view that the onset is the initial functional unit that is activated when naming Thai visual words/pseudowords using the masked priming paradigm.
跨语言研究表明，用于构建正字法语音表征的初始单元在不同语言之间可能会有所不同，并且与该语言的特定特征相关。泰语特别有趣，因为它兼具音节和音素特征。我们使用掩蔽启动范式，研究了在命名单音节泰语单词（实验1）和假词（实验2）时最初被激活的功能单元。在实验1中，对起始音启动和相同（起始音+元音）条件的反应时间没有显著差异，但都显著快于对照启动（起始音不同）。在实验2中，使用了假词，以便研究正字法元音位置的影响。在泰语中，元音在书写时可以在辅音之前，但在语音上跟在辅音之后（例如，书面单词“odg”会读作/dog/），而其他元音则按书写顺序发音。与实验1的结果相似，因为相同启动并没有比起始辅音启动产生更大的促进作用。值得注意的是，由于正字法元音位置没有产生正字法效应。这些结果支持了这样一种观点，即起始音是在使用掩蔽启动范式命名泰语视觉单词/假词时最初被激活的功能单元。
