Daily-life decisions and judgments are often made "intuitively", i.e., without an explicit explanation or verbal justification. We conceive of intuition as the capacity for an effortless evaluation of complex situations on the basis of information being activated, but at the moment of decision not being consciously retrieved. Little is known about which neural processes mediate intuitive judgments and whether these are distinct from those neural processes underlying explicit judgments. Employing functional magnetic resonance imaging (fMRI) we show that intuitive compared to explicit judgments in a semantic coherence judgment task are associated with increased neural activity in heteromodal association areas in bilateral inferior parietal and right superior temporal cortex. These results indicate that intuitive coherence judgments activate neural systems that are involved in the integration of remote associates into a coherent representation and, thus, support the assumption that intuitive judgments are based on an activation of widespread semantic networks sparing a conscious representation.
日常生活中的决策和判断通常是“直觉地”做出的，也就是说，没有明确的解释或言语上的理由。我们将直觉理解为基于被激活的信息对复杂情况进行轻松评估的能力，但在决策时刻这些信息并未被有意识地检索。关于哪些神经过程介导直觉判断，以及这些过程是否与明确判断所基于的神经过程不同，我们知之甚少。通过功能磁共振成像（fMRI），我们发现，在语义连贯判断任务中，与明确判断相比，直觉判断与双侧下顶叶和右侧颞上回的异模态联合区域神经活动增加有关。这些结果表明，直觉连贯判断激活了参与将远距离联想整合为连贯表征的神经系统，因此支持了直觉判断基于广泛语义网络的激活而无需有意识表征这一假设。
