Brain activation was examined using functional magnetic resonance imaging during mathematical problem solving in 7 young healthy participants. Problems were selected from the Necessary Arithmetic Operations Test (NAOT; R. B. Ekstrom, J. W. French, H. H. Harman, & D. Dermen, 1976). Participants solved 3 types of problems: 2-operation problems requiring mathematical reasoning and text processing, 1-operation problems requiring text processing but minimal mathematical reasoning, and 0-operation problems requiring minimal text processing and controlling sensorimotor demands of the NAOT problems. Two-operation problems yielded major activations in bilateral frontal regions similar to those found in other problem-solving tasks, indicating that the processes mediated by these regions subserve many forms of reasoning. Findings suggest a dissociation in mathematical problem solving between reasoning, mediated by frontal cortex, and text processing, mediated by temporal cortex.
在7名年轻健康参与者进行数学问题解决过程中，使用功能磁共振成像检查大脑激活情况。问题选自必要算术运算测试（NAOT；R.B.埃克斯特龙、J.W.弗伦奇、H.H.哈曼和D.德门，1976年）。参与者解决3种类型的问题：需要数学推理和文本处理的两步运算问题、需要文本处理但数学推理最少的一步运算问题，以及需要最少文本处理并控制NAOT问题的感觉运动需求的零步运算问题。两步运算问题在双侧额叶区域产生了主要激活，类似于在其他问题解决任务中发现的激活，这表明这些区域介导的过程服务于多种形式的推理。研究结果表明，在数学问题解决中，由额叶皮层介导的推理和由颞叶皮层介导的文本处理之间存在分离。
