使用事件相关的功能磁共振成像来检查形态学处理由存储条目的心理词典和一组基于规则的心理计算支持的假设。如果规则加记忆模型（Pinker，1999）反映了语言能力的实际组织，那么在产生德语不规则和规则名词和动词变化时，应该观察到两种不同的大脑激活模式。如果规则与记忆模型（Rumelhart & McClelland，1986，以及此后的许多其他模型）的联结主义替代方案（旨在解释单一联想记忆机制中不规则形式和规则形式的产生）是正确的，那么德语规则和不规则变形之间不应该存在神经差异。我们报告的结果支持常规者与不规则者存在显着不同的激活模式，这一结果与两部分规则加记忆帐户一致。 (C) 2003 年爱思唯尔科学（美国）。版权所有。
The hypothesis that morphological processing is supported by a mental dictionary of stored entries plus a set of mental computations based on rules is examined using event-related fMRI. If a rules-plus-memory model (Pinker, 1999) reflects the actual organization of the language faculty, two distinct patterns of brain activation should be observed for production of German irregular and regular noun and verb inflections. If a connectionist alternative to the rules-and-memory model (Rumelhart & McClelland, 1986, and many others since), which seeks to explain the production of both irregular and regular forms within a single associative memory mechanism, is correct, there should be no neural differentiation between German regular and irregular inflection. The results we report support the existence of substantially differing patterns of activation for regulars vs. irregulars, an outcome that is consistent with the two-component rules-plus-memory account.
