Event-related brain potentials (ERP) are important neural correlates of cognitive processes. In the domain of language processing, the N400 and P600 reflect lexical-semantic integration and syntactic processing problems, respectively. We suggest an interpretation of these markers in terms of dynamical system theory and present two nonlinear dynamical models for syntactic computations where different processing strategies correspond to functionally different regions in the system's phase space.
事件相关脑电位 (ERP) 是认知过程的重要神经相关物。在语言处理领域,N400 和 P600 分别反映词汇语义整合和句法处理问题。我们根据动力系统理论对这些标记进行解释,并提出两个用于句法计算的非线性动力模型,其中不同的处理策略对应于系统相空间中功能不同的区域。
