The current study investigates reading aloud words in Persian, a language that does not mark all its vowels in the script. Behaviorally, a masked onset priming effect (MOPE) was revealed for transparent words, with faster speech onset latencies in the phoneme-matching condition (i.e. phonological prime and target onset overlap; e.g. [symbol: see text] /sɒːl/; 'year' [symbol: see text] /sot/; 'voice') than the phoneme-mismatching condition (e.g. [symbol: see text] /tɒːb/ 'swing' - [symbol: see text] /sot/; 'voice'). For opaque target words (e.g. [symbol: see text] /solh/; 'peace'), no such effect was found. However, event-related potentials (ERPs) did reveal an amplitude difference between the two prime conditions in the 80-160 ms time window for transparent as well as opaque words. Only for the former, this effect continued into the 300-480 ms time window. This finding constrains the time course of the MOPE and suggests the simultaneous activation of both the non-lexical grapheme-to-phoneme and the lexical route in the dual-route cascaded (DRC) model.
本研究调查了在波斯语中朗读单词的情况，波斯语在其书写系统中并不标记所有元音。行为研究表明，在透明词中存在掩蔽起始促进效应（MOPE），在音位匹配条件（即音位前导和目标起始重叠；例如 [symbol: see text] /sɒːl/; 'year' [symbol: see text] /sot/; 'voice'）下，语音起始潜伏期更快，而在音位不匹配条件（例如 [symbol: see text] /tɒːb/ 'swing' - [symbol: see text] /sot/; 'voice'）下则较慢。对于不透明的目标词（例如 [symbol: see text] /solh/; 'peace'），则没有发现这种效应。然而，事件相关电位（ERPs）确实在 80-160ms 的时间窗口内揭示了两种前导条件之间的透明词和不透明词的振幅差异。只有在前一种情况下，这种效应持续到 300-480ms 的时间窗口。这一发现限制了 MOPE 的时间进程，并表明在双重路径级联（DRC）模型中，非词汇图形到音位和词汇路径同时被激活。
