Linguistic Aphasiological investigation on the nature of syntax and semantics

我们的研究提供了一组新的脑损伤失语患者和正常人对日语中-sa和-mi两个名义后缀加工的实验数据。他们在生产力方面的差异，正如正常成年人的实验所证实的那样，为衍生形态中存在生产规则过程提供了证据，并通过将衍生形态纳入其范围，支持了双机制模型的有效性。对失语患者的实验揭示了一种分离，这表明两种后缀过程涉及两种不同的神经机制，并为这两种后缀的生产力差异是定性的而不是程度的问题提供了重要证据。

Our research presented a new set of experimental data from brain-damaged aphasic patients as well as normals on the processing of two nominal suffixes in Japanese, i.e. -sa and -mi. Their difference with respect to productivity, as confirmed by the experiment on normal adults, provides evidence for the existence of a productive rule-like process in derivational morphology and supports the validity of the dual-mechanism model by integrating derivational morphology in its scope. The experiment on aphasic patients revealed a dissociation, which demonstrates that the two suffixation processes involve two different neurological mechanisms, and provides crucial evidence for the claim that the difference in the productivity of these two suffixes is of a qualitative nature and not a matter of degree.
