Relationship between psychometric intelligence measured with Raven's Advanced Progressive Matrices (RAPM) and event-related potentials (ERP) was examined using 3-stimulus oddball task. Subjects who had scored higher on RAPM exhibited larger amplitude of P3a component. Additional analysis using the Standardized Low Resolution Electromagnetic Tomography (sLORETA) revealed that this effect corresponds with stronger activity within the frontal cortex and the cingulate gyrus. High intelligence can also be linked with greater P3b response and stronger activity within the parietal cortex and the posterior cingulate gyrus. It may be concluded that the processes related to the initial stage of attention engagement as indexed by P3a, as well as the later stimulus evaluation and classification reflected in P3b, are more intense in subjects scoring higher on RAPM. The quality of mental abilities can therefore be related to differences of the activity in frontal and parietal brain regions.
使用三刺激Oddball 任务研究了瑞文标准推理测验(Raven's Advanced Progressive Matrices,RAPM)测量的心理智力与事件相关电位(event-related potentials,ERP)之间的关系。在 RAPM 中得分较高的受试者表现出 P3a 成分的振幅更大。使用标准化低分辨率电磁断层成像术(Standardized Low Resolution Electromagnetic Tomography,sLORETA)的进一步分析表明,这种效应与额叶皮层和扣带回的活动增强相对应。高智力也可能与更大的 P3b 反应以及顶叶皮层和后扣带回的更强活动有关。可以得出结论,与 P3a 所代表的注意初始阶段相关的过程,以及 P3b 中反映的后期刺激评估和分类,在 RAPM 得分较高的受试者中更为强烈。因此,心理能力的质量可能与额叶和顶叶脑区活动的差异有关。
