关系推理是流体智力的一个重要组成部分，并且已知具有延长的发展轨迹。到目前为止，人们对推理能力提高的神经变化知之甚少。在这项与事件相关的功能磁共振成像（fMRI）研究中，8-12岁的儿童和18-25岁的成年人执行了改编自Raven's Progressive Matrices的关系推理任务。该任务包括三个层次的关系推理需求：REL-0，REL-1和REL-2。儿童表现出不成比例的准确性低于成年人的试验，需要整合的两个关系（REL-2）。像成年人一样，儿童在任务执行过程中参与了外侧前额叶皮层（PFC）和顶叶皮层;然而，他们表现出不同的时间进程和激活模式，从而深入了解他们解决问题的方法。与之前的研究一样，当需要关系整合时，成人的头外侧PFC（RLPFC）激活增加（REL-2 > REL-1，REL-0）。儿童也从事RLPFC最强烈的REL-2的问题在早期阶段的处理，但这种差异激活相对于REL-1试验并没有持续整个试验。这些结果表明，儿童招募RLPFC，而处理关系，但未能使用它来整合两个关系。关系整合是解决各种问题的关键，并为欣赏类比;目前的研究结果表明，在这一功能的发展改善依赖于参与RLPFC，以及背外侧PFC和顶叶皮层的配置文件的变化。
Relational reasoning is an essential component of fluid intelligence, and is known to have a protracted developmental trajectory. To date, little is known about the neural changes that underlie improvements in reasoning ability over development. In this event-related functional magnetic resonance imaging (fMRI) study, children aged 8-12 and adults aged 18-25 performed a relational reasoning task adapted from Raven’s Progressive Matrices. The task included three levels of relational reasoning demands: REL-0, REL-1, and REL-2. Children exhibited disproportionately lower accuracy than adults on trials that required integration of two relations (REL-2). Like adults, children engaged lateral prefrontal cortex (PFC) and parietal cortex during task performance; however, they exhibited different timecourses and activation profiles, providing insight into their approach to the problems. As in prior studies, adults exhibited increased rostrolateral PFC (RLPFC) activation when relational integration was required (REL-2 > REL-1, REL-0). Children also engaged RLPFC most strongly for REL-2 problems at early stages of processing, but this differential activation relative to REL-1 trials was not sustained throughout the trial. These results suggest that the children recruited RLPFC while processing relations, but failed to use it to integrate across two relations. Relational integration is critical for solving a variety of problems, and for appreciating analogies; the current findings suggest that developmental improvements in this function rely on changes in the profile of engagement of RLPFC, as well as dorsolateral PFC and parietal cortex.
