Two experiments investigated phonological, derivational-morphological and semantic aspects of grammatical gender assignment in a perception and a production task in German aphasic patients and age-matched controls. The agreement of a gender indicating adjective (feminine, masculine or neuter) and a noun was evaluated during perception in Experiment 1 (grammaticality judgment). In Experiment 2 the same participants had to produce the matching definite article to a noun. In the perception task patients with left frontal lesions (LF) made more errors during phonological gender assignment as compared to derivational-morphological and semantic gender assignment, while patients with lesions of the posterior superior temporal gyrus (pSTG) made more errors in derivational-morphological gender assignment as compared to phonological and semantic gender assignment. In the production task no differences between patient groups were found. These data support previous evidence that left frontal brain areas are critically involved in phonological processing. The pSTG on the other hand may be critically engaged in the integration of phonological and lexical information essential for phonological and derivational-morphological gender assignment.
两项实验在德国失语症患者及年龄匹配的对照组的感知和生成任务中，研究了语法性属分配的语音、派生形态和语义方面。在实验1（语法判断）的感知过程中，评估了表示性属的形容词（阴性、阳性或中性）与名词的一致性。在实验2中，相同的参与者必须为名词生成匹配的定冠词。在感知任务中，与派生形态和语义性属分配相比，左侧额叶病变（LF）患者在语音性属分配过程中犯的错误更多，而颞上回后部（pSTG）病变患者在派生形态性属分配中犯的错误比语音和语义性属分配更多。在生成任务中，未发现患者组之间存在差异。这些数据支持了先前的证据，即左侧额叶脑区在语音处理中起关键作用。另一方面，pSTG可能在语音和派生形态性属分配所必需的语音和词汇信息整合中起关键作用。
