The Selective Impairment of the Phonological Output Buffer: Evidence From a Chinese Patient

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.
