流体推理，或逻辑思维和解决新问题的能力，是人类认知发展的核心，但对潜在的神经变化知之甚少。在获取事件相关fMRI数据的过程中，6-13岁的儿童（N = 16）和年轻人（N = 17）执行了一项任务，要求他们识别常见物体的图画之间的语义关系。在语义问题上，参与者指出五个对象中的哪一个与线索对象的语义关系最密切。在类比问题上，参与者解决了一个视觉命题类比（例如，（鞋对脚就像手套对......）通过指出四个对象中的哪一个将完成问题;这些问题需要两个语义关系的集成，或关系集成。我们以前的研究在成人类比推理牵连左前腹外侧前额叶皮层（VLPFC）在个人语义关系的控制检索，和吻外侧前额叶皮层（RLPFC）在关系整合。在这项研究中，在检索个体语义关系的过程中，观察到了VLPFC、颞叶皮质和其他皮质区域的募集与年龄相关的变化。与此相反，年龄相关的RLPFC功能的变化，观察在关系整合。6-13岁的儿童在类比试验中参与RLPFC太晚，无法影响他们的行为反应，这表明RLPFC功能的重要变化发生在青春期。
Fluid reasoning, or the capacity to think logically and solve novel problems, is central to the development of human cognition, but little is known about the underlying neural changes. During the acquisition of event-related fMRI data, children aged 6–13 (N = 16) and young adults (N = 17) performed a task in which they were asked to identify semantic relationships between drawings of common objects. On semantic problems, participants indicated which of five objects was most closely semantically related to a cued object. On analogy problems, participants solved a visual propositional analogy (e.g., shoe is to foot as glove is to…?) by indicating which of four objects would complete the problem; these problems required integration of two semantic relations, or relational integration. Our prior research on analogical reasoning in adults implicated left anterior ventrolateral prefrontal cortex (VLPFC) in the controlled retrieval of individual semantic relationships, and rostrolateral prefrontal cortex (RLPFC) in relational integration. In this study, age-related changes in the recruitment of VLPFC, temporal cortex, and other cortical regions were observed during the retrieval of individual semantic relations. In contrast, age-related changes in RLPFC function were observed during relational integration. Children aged 6–13 engage RLPFC too late in the analogy trials to influence their behavioral responses, suggesting that important changes in RLPFC function take place during adolescence.
