概念扩展是我们创造性思维能力的基础。在本事件相关的功能磁共振成像研究中，一个修改后的替代用途任务被用来确定在被动的概念扩展过程中涉及的大脑区域，从而分别评估创造性输出的两个定义元素的影响：独创性（unusualness）和相关性（appropriately）。参与者查看由一个对象和一个用途组成的单词对，并指出给定的用途是否不寻常和/或适合给定的对象。将被判定为不寻常和适当的对象-使用组合（HUHA）的试验与被判定为只是不寻常但不适当（HALTH）或只是适当但不寻常（LUHA）的试验进行对比。根据推测，概念扩展相关激活（HUHA）主要位于双侧额下回（BA 45，47）、左侧颞极（BA 38）和左侧额极皮层（BA 10）。我们讨论的具体贡献，这些地区的语义认知。
Conceptual expansion is a key process that underlies our ability to think creatively. In the present event-related fMRI study, a modified Alternate Uses Task was used to identify brain regions involved during passive conceptual expansion and thereby separately assess the effects of the two defining elements of creative output: Originality (unusualness) and Relevance (appropriateness). Participants viewed word pairs consisting of an object and a use and indicated whether the given use was unusual and/or appropriate for the given object. Trials with object-use combinations judged as unusual and appropriate (HUHA) were contrasted against trials judged as just unusual but inappropriate (HULA) or just appropriate but not unusual (LUHA). As hypothesized, conceptual expansion related activation (HUHA) was found in the bilateral inferior frontal gyrus (BA 45, 47), left temporal pole (BA 38) and left frontopolar cortex (BA 10). We discuss the specific contributions of these regions with reference to semantic cognition.
