The aims of the present ERP study were twofold. First, to determine whether a previous study on creative cognition could be replicated, and second, to extend these findings by examining individual differences in creativity. Conceptual expansion, a capacity that is central to creativity, was induced via the processing of novel metaphors. Brain activity patterns in relation to these were compared to the processing of literal and nonsense phrases. The previous findings were replicated in that the N400, known for its sensitivity to semantic anomalies, indexed the originality of the phrases, while a post-N400 late component (LC), which is linked to semantic integration processes, indexed the appropriateness of the phrases. Moreover, only the LC was significantly sensitive to individual differences in creativity in the processing of these phrases. Differences at the level of semantic integration processes as well as the structure of knowledge organization are thereby implicated in individual differences in creativity.

本 ERP 研究的目的是双重的。首先，确定是否可以复制先前关于创造性认知的研究，其次，通过检查创造力的个体差异来扩展这些发现。概念扩展是创造力的核心能力，它是通过处理新的隐喻引起的。与这些相关的大脑活动模式与文字和无意义短语的处理进行了比较。之前的发现被重复，因为以对语义异常的敏感性而闻名的 N400 索引了短语的原创性，而 N400 后的后期组件 (LC) 与语义整合过程相关，索引了短语的适当性. 此外，只有 LC 对处理这些短语的创造力的个体差异显着敏感。
