本研究探讨了评价性判断的神经基础。判断可以被定义为在内部尺度上对外部或内部刺激的评估，它们是决策和其他认知过程的基础。评价性判断（我喜欢乔治·W.布什：是/否）是一种特殊类型的判断，其中内部尺度与人的价值体系（偏好、规范、审美价值等）有关。我们使用功能性磁共振成像来检查大脑激活过程中的评价性判断，而不是情节和语义记忆检索。评价性判断在前额叶中皮层（BA 10/9）、下楔前叶（BA 23/31）和左下前额叶皮层（BA 45/47）产生显著激活。结果表明，在前额叶中皮层和下楔前叶的激活之间的功能分离。后者主要是激活的情节检索过程，支持其功能作为一个多模态的关联区，整合检索和新呈现的信息的不同方面。相比之下，前额叶中皮层主要参与评价性判断，支持其在自我参照过程和自我启动认知过程中的作用。(C)2002 Elsevier Science（美国）。
This study investigated the neuronal basis of evaluative judgment. Judgments can be defined as the assessment of an external or internal stimulus on an internal scale and they are fundamental for decision-making and other cognitive processes. Evaluative judgments (I like George W. Bush: yes/no) are a special type of judgment, in which the internal scale is related to the person's value system (preferences, norms, aesthetic values, etc.). We used functional magnetic resonance imaging to examine brain activation during the performance of evaluative judgments as opposed to episodic and semantic memory retrieval. Evaluative judgment produced significant activation in the anterior frontomedian cortex (BA 10/9), the inferior precuneus (BA 23/31), and the left inferior prefrontal cortex (BA 45/47). The results show a functional dissociation between the activations in the anterior frontomedian cortex and in the inferior precuneus. The latter was mainly activated by episodic retrieval processes, supporting its function as a multimodal association area that integrates the different aspects of retrieved and newly presented information. In contrast, the anterior frontomedian cortex was mainly involved in evaluative judgments, supporting its role in self-referential processes and in the self-initiation of cognitive processes.
