What is the route that is used for writing non‐words to dictation? Does it have to pass through phonological output? Two possibilities are found in the literature. In one, writing non‐words requires access from the phonological input buffer to the phonological output buffer and from there, via phoneme‐to‐grapheme conversion, to the orthographic output buffer. The second approach maintains that writing non‐words can proceed directly from the phonological input buffer to the orthographic output buffer. In this study, we discriminate between these two options using a cognitive neuropsychological approach. Specifically, we present a multiple case study of 24 individuals with a developmental impairment to the phonological output buffer, who nevertheless show unimpaired non‐word writing. These data lead to the conclusion that the phonological output buffer is not necessary when writing non‐words and that writing non‐words to dictation can proceed directly from the phonological input buffer to the orthographic output buffer. We suggest that the cognitive assumption that non‐word writing proceeds through the phonological output buffer may have resulted from graphic conventions and the depiction of the lexical processing model: in the common depiction of the model drawing a line through the phonological output buffer is visually simpler than a direct line (which would require lines to cross or long bypass lines).

非单词写作不需要语音输出缓冲：直接语音拼写法路线的神经心理学证据。

将非单词写成听写的路线是什么？它必须通过语音输出吗？在文献中发现了两种可能性。在一种情况下，写非单词需要从语音输入缓冲区访问语音输出缓冲区，然后再通过音素到字素转换访问拼字输出缓冲区。第二种方法认为，写非单词可以直接从语音输入缓冲区到正字输出缓冲区。在这项研究中，我们使用认知神经心理学方法来区分这两种选择。具体而言，我们提出了一个多案例研究，涉及24个个体，这些个体在语音输出缓冲方面有发育障碍，但是他们表现出无障碍的非单词写作能力。这些数据得出的结论是，在写非单词时不需要语音输出缓冲区，并且可以将非单词写到听写中直接从语音输入缓冲区到正字输出缓冲区。我们建议认知假设，即非单词通过语音输出缓冲区进行书写可能是由于图形惯例和词汇处理模型的描述所致：在模型的常见描述中，通过语音输出缓冲区画一条线在视觉上更简单而不是直接线（这将要求线交叉或较长的旁路线）。
