本研究探讨了在线理解的限定词短语（DP）作为一个功能的新的区别在两句话的文本在德国，并进一步侧重于DP的解释依赖于推理信息（所谓的“桥接关系”）。先前的反应时间研究报告了给定信息相对于新信息的优势。在本研究中，这种差异反映在不同的神经机制中：事件相关电位揭示了先前引入的（即，给定）DP引起降低的N400，而新DP显示增强的N400，随后是P600。至关重要的是，假设与新的和给定的信息共享属性的非线性桥接DP，首先与给定的DP（显示衰减的N400），然后与新的DP（显示增强的P600）模式。数据表明，DP和先前的上下文之间的显着关系，缓解DP整合和额外的成本产生的独立参考的建立。他们进一步表明，加工成本与解释桥接DP的结果从回指的复杂性，引入一个独立的所指。(c)2006年爱思唯尔公司All rights reserved.
This study investigates the online comprehension of Determiner Phrases (DPs) as a function of the given-new distinction in two-sentence texts in German and further focuses on DPs whose interpretation depends on inferential information (so-called 'bridging relations'). Previous reaction time studies report an advantage of given over new information. In the present study, this difference is reflected in distinct neural mechanisms: event-related potentials reveal that previously introduced (i.e., given) DPs elicit a reduced N400, while new DPs show an enhanced N400 followed by a P600. Crucially, inferentially bridged DPs, which are hypothesized to share properties with new and given information, first pattern with given DPs (showing an attenuated N400) and then with new DPs (showing an enhanced P600). The data demonstrate that salience relations between DPs and prior context ease DP integration and that additional cost arises from the establishment of independent reference. They further reveal that processing cost associated with the interpretation of bridged DPs results from the anaphoric complexity of introducing an independent referent. (c) 2006 Elsevier Inc.
