为了了解不同的心理或意向状态是如何在大脑中加工的，本研究通过功能性磁共振成像（fMRI）研究了信念意向状态相对于欲望意向状态的归因过程中大脑的相关关系，以及不一致意向状态相对于一致意向状态的影响。为此，向参与者展示了包含情景的句子，他们的任务是根据这些信息对意图状态的归属做出判断。相对于欲望归因，信念归因伴随着侧额叶前部结构的激活，其中包括已知涉及关系和概念推理的区域。相反，欲望归属伴随着内侧前额叶皮层、颞上回和海马形成区域的激活，所有这些区域都以参与自我参照、自传体和情景记忆相关过程而闻名。此外，与现实不一致的意向状态（错误信念和未实现的欲望）的归属与与现实一致的意向状态（真实信念和满足的欲望）的归属进行了比较。虽然在处理未实现的欲望时，没有选择性地激活大脑区域，但在处理错误信念的过程中，前额叶背内侧皮层的激活更强，这一区域先前与错误信念归因的解耦过程有关。这些发现为精神状态推理的更细致的方面提供了新的见解。
With the aim of understanding how different mental or intentional states are processed in the brain, the present functional magnetic resonance imaging (fMRI) study examined the brain correlates during the ascription of belief intentional states relative to desire intentional states as well as the effect of incongruent relative to congruent intentional states. To this end, sentences containing scenarios were presented to participants and their task was to make judgments concerning the ascription of intentional states based on this information. Belief ascriptions, relative to desire ascriptions, were accompanied by activations in lateral prefrontal structures that include areas known to be involved in relational and conceptual reasoning. Desire ascriptions, in contrast, were accompanied by activations in regions of the medial prefrontal cortex, superior temporal gyri and hippocampal formation, all of which are known for their involvement in self-referential, autobiographical and episodic memory-relevant processes. In addition, the ascription of intentional states that were incongruent with reality (false beliefs and unfulfilled desires) was compared to the ascription of intentional states that were congruent to reality (true belief and fulfilled desires). While no brain region was selectively activated during the processing of unfulfilled desires, the processing of false beliefs was associated with stronger activations in the dorsal medial prefrontal cortex, an area that has been previously linked to the process of decoupling in false belief attribution. These findings provide new insights into more fine-grained aspects of mental state reasoning.
