在神经成像研究中，任务复杂性的增加可能会导致任务特定区域的激活增加，或者导致额外区域的激活。在归纳推理过程中，大脑如何适应增加的规则复杂性仍不清楚。本研究设计了三种类型的问题：简单规则归纳(SI，规则复杂性为1)、复杂规则归纳(CI，规则复杂性为2)和知觉控制。我们的发现表明，右侧背侧外侧前额叶皮质(DLPFC)和内侧后顶叶皮质(楔前叶)的激活增加伴随着规则复杂性的增加。认知模型同时预测了行为和大脑成像结果。目前的发现表明，额叶和顶叶区域的神经活动受到规则复杂性的调节，这可能有助于揭示归纳推理的神经机制。(C)爱思唯尔有限公司出版的2014年。
In neuroimaging studies, increased task complexity can lead to increased activation in task-specific regions or to activation of additional regions. How the brain adapts to increased rule complexity during inductive reasoning remains unclear. In the current study, three types of problems were created: simple rule induction (i.e., SI, with rule complexity of 1), complex rule induction (i.e., CI, with rule complexity of 2), and perceptual control. Our findings revealed that increased activations accompany increased rule complexity in the right dorsal lateral prefrontal cortex (DLPFC) and medial posterior parietal cortex (precuneus). A cognitive model predicted both the behavioral and brain imaging results. The current findings suggest that neural activity in frontal and parietal regions is modulated by rule complexity, which may shed light on the neural mechanisms of inductive reasoning.
