概括
集中注意力 (FA) 冥想,特别是咒语冥想,并没有改变专家与新手之间的不匹配消极性 (MMN) 幅度. 冥想 冥想 冥想 冥想
科学领域:
- 认知神经科学 认知神经科学
- 冥想的神经科学 冥想的神经科学
背景情况:
- 冥想研究使人们对冥想的认知效应有了更深入的了解,特别是长期 (特征) 益处.
- 神经成像研究使用神经标志物,如不匹配负面性 (MMN) 来评估冥想对注意力的影响.
- 以前对集中注意力 (FA) 冥想对MMN的特征影响的研究 yielded不一致的结果,可能是由于状态效应和专注于基于呼吸的技术.
研究的目的:
- 调查咒语冥想,FA冥想的一种形式,对MMN的特征效应.
- 通过使用充足的动力样本和检查不同的FA冥想技术来解决现有文献中的混合发现.
- 用强度奇怪范式在MMN生成中区分高阶认知过程和感官适应.
主要方法:
- 采用强度奇特的范式来测量冥想专家和新手的不匹配消极性 (MMN).
- 利用充足的动力样本大小来确保统计学稳定性.
- 评估与事件相关的潜力 (ERP),以应对偏差的听觉刺激.
主要成果:
- 冥想专家和新手之间没有观察到MMN振幅的显著差异.
- 观察到事件相关的潜在与偏差刺激的单向极性转移.
- 研究结果表明,MMN可能对冥想专业知识不敏感,或者受到新手注意力技能的影响.
结论:
- 该研究表明,MMN振幅不是在集中注意力 (FA) 冥想中冥想专业知识的可靠神经标志物.
- 冥想对MMN的影响可能与更高级的偏差检测机制有关,而不是感官适应.
- 未来的研究应该探索其他冥想类型和神经标记,以充分理解冥想的认知特征效应.

High-Level and Low-Level Awareness
245
Controlled processes in human consciousness represent high-alert mental states where individuals deliberately focus their attention on achieving specific goals. Controlled processes can be seen in situations like mastering new technology, where a person might become so absorbed that they ignore surrounding distractions. Such processes involve selective attention, requiring one to concentrate on particular elements of experience while disregarding others. These are governed by executive...

Altered States of Awareness
146
Altered states of consciousness represent significant deviations from one's normal mental state. These deviations can range from subtle changes in awareness to profound transformations in perception, thought processes, and sensory experiences. Altered states of consciousness can be triggered by various factors, including drug use, meditation, hypnosis, illness, or even intense fatigue.
