【摘要】：目的本研究将不同人格的大学生作为研究对象,通过意境作业干预训练,应用视觉事件相关电位(ERP)检测各阶段的变化反应,分析意境作业对不同人格大学生的ERP效应差异,为临床心理精神性疾病的防治提供实验学证据,以丰富中医气功学和中医心理学理论。方法本研究为国家自然基金项目"意境作业安神解郁作用的ERP效应及分子机制研究"的前期研究,以人格特质为切入点,以问卷形式收集数据,分析大学生群体的不同人格特质的状况。随后,使用ERP技术,探讨不同人格个体对情绪刺激的脑电反应特点。给予气功干预后,再次观察不同人格个体的脑电反应特点,探寻意境作业的人格脑功能特异性,为临床防治心身疾病和辨证施功提供科学实验依据。结果1.参加本次量表普查的323人结果显示,外向组中,N分高和N分低的人群人数基本均衡,即外向与情绪稳定并无直接联系;内向组中,N分高的人群占绝大多数,N分低的人群人数较少,即内向人群中,情绪不稳定者占大多数。2.首先将参加脑电实验的受试者按照内外向维度进行分组,使用三种情绪刺激引出各组的LPP波幅,发现在各个导联和刺激中,LPP波形的平均幅值在三组中均无差异;再将受试者按照神经质维度进行分组,使用三种情绪刺激引出各组的LPP波幅,发现在各个导联和刺激中,高神经质组在观看正性和负性刺激时,所引发出的晚正成分波幅最小。低神经质组在观看负性刺激时,所引发出的晚正成分波幅最大,中间组介于两者之间。3.意境作业的干预对受试起到效果,在内外向维度和神经质维度中,均有多组导联的LPP平均幅值出现前后差异,即不论受试者的人格差异,在意境作业的干预后,均会出现LPP平均幅值的变化。4.比较干预后,不同内外向维度的三组受试者LPP幅值,发现与干预前并无差异;比较干预后,不同神经质维度的三组受试者LPP幅值,发现仅在中性情绪刺激下,额区(FP2)导联出现差异,在其他刺激中均无差异。说明意境作业的干预,对不同神经质维度受试者的情绪反应,具有趋于同步的特点。结论经普查发现,人格内向兼有高神经质人群比例较大,内向兼有低神经质人群比例偏小。ERP脑电诱发电位中,晚正成分与人格的神经症维度密切相关,与人格的内外向维度不相关。意境作业的干预,能较大降低高神经质人群的脑电晚正成分波幅,使之与低神经质人群趋同。意境作业针对外向型人格个体,可能具有使其安静平稳的效果。
[Abstract]:Objective in this study, college students with different personality were used as the research objects, and the visual event-related potentials (VEP) were used to detect the change response of different stages through the intervention training of artistic conception homework, and to analyze the difference of the ERP effect of artistic conception work on different personality college students. To provide experimental evidence for the prevention and treatment of psychological and psychiatric diseases in order to enrich the theory of Qigong and psychology of TCM. Methods this study was a preliminary study on the ERP effect and the molecular mechanism of the effect of soothing the mind and relieving depression in the National Natural Fund project, with personality traits as the starting point and data collected in the form of questionnaires. This paper analyzes the status of different personality traits of college students. Then, ERP technique was used to study the EEG response characteristics of different personality individuals to emotional stimulation. After Qigong intervention, the characteristics of EEG response of individuals with different personality were observed again, and the specificity of personality brain function was explored, which provided scientific experimental basis for clinical prevention and treatment of psychosomatic diseases and syndrome differentiation. Result 1. The results of 323 participants in the questionnaire showed that there was no direct relationship between extroversion and emotional stability in the extroverted group with high N score and low N score. In the introverted group, the people with high N score accounted for the majority of the population with low N score, that is, in the introverted group, the emotional instability accounted for the majority of .2. The subjects who participated in the EEG experiment were divided into three groups according to their internal and external dimensions. The amplitude of LPP waves in each group was induced by three kinds of emotional stimuli. The average amplitude of LPP waveforms in each lead and stimulus was not different among the three groups. Then the subjects were grouped according to the neuroticism dimension and the amplitude of LPP was induced by three kinds of emotional stimuli. It was found that the amplitude of late positive component was the least in the high neurotic group when watching the positive and negative stimuli. In the low neurotic group, the amplitude of the late positive component was the largest when watching the negative stimulation, and the middle group was between the two groups. There were significant differences in the average amplitude of LPP between groups of leads in the introverted dimension and neuroticism dimension, that is, regardless of the personality difference of the subjects, after the intervention of the artistic conception operation, there were significant differences in the mean amplitude of LPP between the two groups. There will be a change in the average amplitude of LPP. 4. 4. After the intervention, there was no difference in the amplitude of LPP between the three groups of subjects with different introversion and introversion dimension, and the amplitude of LPP of the three groups of subjects with different neuroticism dimensions was found to be only stimulated by neutral emotion after intervention. There was no difference in lead FP2 in frontal area, but there was no difference in other stimuli. It shows that the intervention of mood assignment tends to synchronize the emotional response of subjects with different neuroticism. Conclusion the results showed that the proportion of introverted and low neurotic population was relatively small. The late positive component was closely related to the dimension of personality neurosis in ERP EEG evoked potential. It has nothing to do with the internal and external dimensions of personality. The intervention of artistic conception can decrease the amplitude of the late positive component of EEG in the high neurotic group and make it converge with the low neurotic group. The artistic conception assignment aims at the extroverted personality individual, may have the effect which makes it quiet and stable.
