本研究考察了句子理解中不相容的语义表征冲突所导致的再分析过程。使用事件相关电位（ERP）技术，我们研究了在世界知识（即，可解释性试探法）与建立在句法规则上的试探法（即，语法分析）。我们发现，句子加工既受到句法结构复杂性的制约，也受到读者认知控制能力的制约。对于具有较高控制能力的读者，如Stroop任务所测量的，当冲突发生在复杂的（即，被动）句子，而在300和600 ms之间观察到前向负性时，冲突发生在简单（即，主动）句子。然而，对于控制能力较低的读者，大脑电位不受句法结构复杂性的影响，在350和750 ms之间获得持续的积极性，发生在主动句和被动句的冲突。这些结果表明，认知控制机制参与了解决不相容的原始表征之间冲突的再分析过程。持续性正性可能与表征冲突的发现和解决有关，而前负性可能与不适当表征或反应倾向的抑制有关。(c)2008 Elsevier B.V.保留所有权利。
This study investigates the reanalysis processes as a consequence of conflict between incompatible sentential representations in sentence comprehension. Using the event-related potential (ERP) technique, we examined the situation in which the sentential representation built upon world knowledge (i.e., the plausibility heuristic) conflicts with the one built upon syntactic rules (i.e., the syntactic analysis). We found that sentence processing is constrained both by the complexity of syntactic structure and by the reader's cognitive control ability. For readers with higher control abilities, as measured by the Stroop task, a sustained positivity was observed between 350 and 850 ms when conflicts occurred in complex (i.e., passive) sentences, whereas an anterior negativity was observed between 300 and 600 ms when conflicts occurred in simple (i.e., active) sentences. For readers with lower control abilities, however, brain potentials were not affected by the complexity of syntactic structure, with a sustained positivity obtained between 350 and 750 ms for conflicts occurring in both active and passive sentences. These results suggest that the mechanisms of cognitive control are involved in the reanalysis processes to resolve conflict between incompatible sentential representations. The sustained positivity is possibly associated with detection and resolution of representational conflict, while the anterior negativity is associated with suppression of inappropriate representation or response tendency.
