我们介绍了一位讲中文的患者 SJ，他在所有涉及口语表达的任务中都会出现语音错误。对不同任务中错误的详细分析表明，阅读、口头图片命名和重复任务的错误模式非常相似，这也与文献中报道的语音缓冲缺陷案例的错误模式相当。错误的性质使我们得出这样的结论：患者的语音输出缓冲器选择性受损。与之前报道的案例不同，SJ 的口语表达任务缺陷并不伴随着类似的写作能力障碍。我们认为，这种分离证明了语音输出缓冲区不参与书写中文单词。此外，大多数 SJ 错误发生在音节开头，这表明缓冲区的结构使音节开头更容易受到损害。
We present a Chinese-speaking patient, SJ, who makes phonological errors across all tasks involving oral production. Detailed analyses of the errors across different tasks reveal that the patterns are very similar for reading, oral picture naming, and repetition tasks, which are also comparable to the error patterns of the phonological buffer deficit cases reported in the literature. The nature of the errors invites us to conclude that the patient's phonological output buffer is selectively impaired. Different from previously reported cases, SJ's deficits in oral production tasks are not accompanied by a similar impairment of writing performance. We argue that this dissociation is evidence that the phonological output buffer is not involved in writing Chinese words. Furthermore, the majority of SJ's errors occur at the onset of a syllable, indicating that the buffer has a structure that makes the onset more prone to impairment.
