本文报告一位聋人“查尔斯”因左侧CVA而出现手语失语症的个案研究。他的失语症的一个显著特征是命名障碍，或者说是符号提取的缺陷，这显示了许多有据可查的言语命名障碍的特征。例如，符号提取对熟悉度敏感，符号提取可以被线索化，符号提取中存在语义错误和语音错误。就像文献中以前的案例一样（Corina，Poizner，Bellugi，Feinberg，Dowd和O 'Grady-Batch，1992），查尔斯表现出了符号和手势之间的惊人分离，因为他的手势制作相对完整。这种分离不受符号象似性的影响。因此，查尔斯的符号产生没有表现出象似性效应，即使在符号和手势的形式相似的情况下，手势的产生也上级符号的产生。这些研究结果的影响模型的标志和手势的生产进行了讨论。
This paper reports a single case investigation of "Charles", a Deaf man with sign language aphasia following a left CVA. Anomia, or a deficit in sign retrieval, was a prominent feature of his aphasia, and this showed many of the well-documented characteristics of speech anomia. For example, sign retrieval was sensitive to familiarity, it could be cued, and there were both semantic and phonological errors. Like a previous case in the literature (Corina, Poizner, Bellugi, Feinberg, Dowd, & O'Grady-Batch, 1992), Charles demonstrated a striking dissociation between sign and gesture, since his gesture production was relatively intact. This dissociation was impervious to the iconicity of signs. So, Charles' sign production showed no effect of iconicity, and gesture production was superior to sign production even when the forms of the signs and gestures were similar. The implications of these findings for models of sign and gesture production are discussed.
