Self-image, conceived as one's mental blueprint and a composite of thoughts, is among the hotly debated topics in psychology. Exploring the brain's structure, functionality, and physiology has also proven crucial in understanding one's self-image. In this vein, the current study aimed to examine the relationship between quantitative electroencephalography (QEEG) findings and medical students' self-image.
To measure self-image, the Offer Self-Image Questionnaire and, for the QEEG findings, a Mitsar EEG-202 device were used. To analyze the QEEG findings, the FDA-approved Neuroguide software was utilized.
In the first phase, out of the 93 questionnaires returned, the maximum score, on a scale of 1 to 6, was 5.52 and the minimum was 2.36. Hence, it could be argued that the medical students who took part in this study had relatively high self-images. Results, however, showed no significant difference between the two genders regarding either their overall self-image score or any of its subcategories. In the second phase, the QEEG analyses of high- and low-self-image students suggested a statistically significant difference in their θ signal of the frontal lobes. Further analysis indicated that the difference was not localized to any single lead or lobe, but pertained to the overall function of the prefrontal cortices.
The relationship observed between medical students' self-image and their brain θ waves could contribute to a better understanding of people's cognitive functions.
自我形象被视为一个人的心理蓝图和思想的综合体，是心理学中备受争议的话题之一。事实证明，探索大脑的结构、功能和生理机能对于理解一个人的自我形象也至关重要。有鉴于此，本研究旨在探讨定量脑电图（QEEG）结果与医学生自我形象之间的关系。
为测量自我形象，使用了奥弗自我形象问卷；对于QEEG结果，使用了一台米萨尔EEG - 202设备。为分析QEEG结果，使用了经美国食品药品监督管理局（FDA）批准的Neuroguide软件。
在第一阶段，在回收的93份问卷中，评分范围为1至6分，最高分为5.52分，最低分为2.36分。因此，可以认为参与本研究的医学生自我形象相对较高。然而，结果显示，在总体自我形象得分或其任何子类别方面，两性之间没有显著差异。在第二阶段，对高自我形象和低自我形象学生的QEEG分析表明，他们额叶的θ信号存在统计学上的显著差异。进一步分析表明，这种差异并非局限于任何单个导联或脑叶，而是与前额叶皮质的整体功能有关。
医学生自我形象与其大脑θ波之间观察到的关系有助于更好地理解人们的认知功能。
