以抽象的条件命题作为实验材料,测定13名大学生在完成MP、AC、DA、MT推理(推测判断任务)和基线任务(记忆判断任务)时的事件相关电位(ERP),初步探讨不同推理类型的脑内时程动态变化.这是使用ERP技术来研究条件推理脑机制的初步尝试.结果发现,五种任务所诱发的ERP早成分均不存在显著差异,在头皮前部的左外侧额区和左颞区,MP与DA推理与基线任务相比,均诱发一个更明显的晚期正成分(450～1100ms),在右外侧额区则诱发一个更明显的晚期负成分(450～1100ms);与之相反,MT与AC推理与基线任务相比,在左侧诱发一个更明显的晚期负成分(450～1100ms),在右侧诱发一个更明显的晚期正成分(450～1100ms),这一结果可能是由于左右脑在推理中的认知功能以及四种推理类型之间存在的差异所致,同时也表明推测过程主要激活了左右侧的前额部、颞叶等区域,基本支持Goel等人的双加工理论. |

Event-related brain potentials were measured when 13 normal young participants finished four kinds of conditional reasoning （MP, AC, DA, MT）tasks and one kind of baseline task（BS）. Results showed that there were no amplitude modulations of early components. However MP and DA elicited a more positive EPR deflection on the left and a more negative EPR deflection on the right hemisphere than did BS task in the time window from 450 - 1100 msec after onset of the stimuli 2. On the contrary MT and AC elicited a more negative EPR deflection on the left and a more positive EPR deflection on the right hemisphere than did BS task in the time window form 450 - 1100 msec. These ERP components elicited by five different tasks might reflect that right and left hemisphere have different ability of cognitive process in reasoning. In additional Voltage map of the difference wave between reasoning tasks and baseline task showed strong activity in frontal-temporal pathway, Our result support dual-process theory （Goel）. |
