Dual-route theories of reading posit that a sublexical reading mechanism that operates serially and from left to right is involved in the orthography-to-phonology computation. These theories attribute the masked onset priming effect (MOPE) and the phonological Stroop effect (PSE) to the serial left-to-right operation of this mechanism. However, both effects may arise during speech planning, in the phonological encoding process, which also occurs serially and from left to right. In the present paper, we sought to determine the locus of serial processing in reading aloud by testing the contrasting predictions that the dual-route and speech planning accounts make in relation to the MOPE and the PSE. The results from three experiments that used the MOPE and the PSE paradigms in English are inconsistent with the idea that these effects arise during speech planning, and consistent with the claim that a sublexical serially operating reading mechanism is involved in the print-to-sound translation. Simulations of the empirical data on the MOPE with the dual route cascaded (DRC) and connectionist dual process (CDP++) models, which are computational implementations of the dual-route theory of reading, provide further support for the dual-route account.
阅读的双通路理论认为，一种从左到右串行运作的次词汇阅读机制参与了从正字法到语音的转换过程。这些理论将掩蔽起始启动效应（MOPE）和语音斯特鲁普效应（PSE）归因于该机制从左到右的串行运作。然而，这两种效应可能在言语计划过程中、同样从左到右串行发生的语音编码过程中出现。在本文中，我们试图通过测试双通路理论和言语计划理论对MOPE和PSE的不同预测，来确定大声朗读时串行加工的位置。三项使用英语MOPE和PSE范式的实验结果与这些效应出现在言语计划过程中的观点不一致，而与一种次词汇串行运作的阅读机制参与从印刷体到语音转换的观点一致。用双通路级联（DRC）模型和联结主义双加工（CDP++）模型对MOPE的实证数据进行模拟，这两种模型都是阅读双通路理论的计算实现方式，为双通路理论提供了进一步支持。
