短期整体身心调节训练对工作记忆的影响研究
发布时间：2019-01-23 12:41
【摘要】：整体身心调节训练(Integrative Body-Mind Training, IBMT)是一种源于中国传统医学和心身一体整体观的完整心身训练方式,该方法可以在较短的时间内提高练习者的注意、自我控制和认知行为能力。同时,针对该方法的神经机制研究也得出,IBMT可以在短期内改变个体大脑的灰质和白质,对个体的大脑具有可塑作用。 工作记忆是人类的认知枢纽,在认知学研究领域具有非常重要的地位,它是一种能够对信息进行暂时性储存和加工的具有能量的记忆系统,对于个体的学习,认知和推理能力等认知功能都起到了重要作用。研究者发现,某些冥想训练方法对练习者的工作记忆有显著的促进作用,但是,在目前的研究领域并没有关于短期IBMT影响工作记忆的研究报道。 基于此,本研究拟从行为认知和神经机制两个方面讨论IBMT对练习者工作记忆的影响。应用dual n-back行为实验范式和静息态功能磁共振方法,对IBMT与西方流行的放松训练的训练效果进行分析比较,比较的时间周期分别为5天和7天。分析对比接受两种不同训练的练习者工作记忆能力的改变和改变趋势,并且研究这种改变的神经机制。 本论文的研究结果总结如下： 1、练习者接受7天IBMT训练后视空间n-back和听觉n-back实验范式的正确率与练习之前相比有显著提高。而参加放松训练的练习者并没有出现视空间n-back任务正确率显著提高的现象。说明IBMT训练后,练习者的视空间工作记忆和听觉工作记忆信息处理效率和准确度显著提高。并且与放松训练相比,IBMT对视空间工作记忆能力的提高更有效果。 2、通过对接受5天IBMT训练前后的静息态数据进行相关性统计分析发现：训练后,与视空间工作记忆有关的额顶叶脑区间功能连通系数与视空间n-back任务正确率的相关性下降,即额顶叶网络对视空间工作记忆负荷的敏感性与训练前相比降低。说明经过IBMT训练后,大脑不需要更多的资源整合便可以完成高负荷视空间工作记忆任务,从而可以提高视空间记忆能力。 本研究结果表明,个体工作记忆能力可以通过IBMT训练进行改善,尤其是视空间工作记忆。IBMT可以提高脑部信息资源整合程度和处理效率,为提高工作记忆能力提供了一种新的方法。
[Abstract]:The whole body and mind training (Integrative Body-Mind Training, IBMT) is a complete psychosomatic training method derived from the traditional Chinese medicine and the whole view of psychosomatic integration. This method can improve the attention of practitioners in a relatively short period of time. Self-control and cognitive behavior. At the same time, it is found that IBMT can change the gray matter and white matter of the brain in a short period of time, and has a plastic effect on the brain. Working memory is the cognitive hub of human beings and plays an important role in the field of cognitive research. It is an energetic memory system that can temporarily store and process information. Cognitive functions, such as cognitive and reasoning abilities, play an important role. The researchers found that some meditation training methods can significantly promote the working memory of practitioners. However, there are no studies on short-term IBMT effects on working memory in the current research field. Based on this, we discuss the effects of IBMT on working memory of practitioners from two aspects: behavioral cognition and neural mechanism. The dual n-back behavioral paradigm and resting functional magnetic resonance (fMRI) were used to analyze and compare the training effects of IBMT and popular relaxation training in the West. The time periods of comparison were 5 days and 7 days, respectively. The changes and changing trends of working memory ability of two different kinds of training practitioners were analyzed and the neural mechanism of the changes was studied. The results of this study are summarized as follows: 1. The correct rate of visual space n-back and auditory n-back experimental paradigm after 7 days of IBMT training was significantly improved compared with that before training. However, there was no significant increase in the correct rate of n-back task in visual space among the practitioners who took part in relaxation training. After IBMT training, the processing efficiency and accuracy of visual spatial working memory and auditory working memory were improved significantly. Compared with relaxation training, IBMT can improve the working memory ability of visual space more effectively. 2. Through the statistical analysis of the rest data before and after 5-day IBMT training, we found that: after training, The correlation between the functional connectivity coefficient of the frontal and parietal lobe and the accuracy rate of the n-back task in the visual space was decreased, that is, the sensitivity of the frontal-parietal network to the working memory load of the visual space was lower than that before training. It shows that after IBMT training, the brain can accomplish the task of working memory in high load space without more integration of resources, which can improve the ability of visual spatial memory. The results show that the ability of individual working memory can be improved by IBMT training, especially visual spatial working memory. IBMT can improve the degree of integration and processing efficiency of brain information resources. It provides a new method for improving working memory ability.
