早期双语者比晚期双语者表现出更灵活的大脑网络,影响认知功能. 获取第二语言的年龄影响动态功能连接模式和大脑横向性.
科学领域:
- 神经科学是一个神经科学.
- 认知科学 认知科学
- 心理语言学 心理语言学
背景情况:
- 双语与增强的认知功能和大脑灵活性有关.
- 双语对动态功能连接 (dFC) 和学习年龄的作用的影响仍然不清楚.
研究的目的:
- 调查早期与晚期双语如何影响大脑的时间变化的功能网络.
- 探索第二语言 (L2) 获取年龄与动态功能连接 (dFC) 模式之间的关系.
主要方法:
- 使用了休息状态功能磁共振成像 (fMRI).
- 在早期双语者 (EB),晚期双语者 (LB) 和单语者中分析了dFC.
- 检查了功能横向性及其与L2熟练程度的相关性.
主要成果:
- 晚期双语者 (LBs) 与单语者相比,在已识别的dFC状态之间显示了更多的过渡.
- 早期的双语者 (EBs) 在多个大脑区域的功能横向性中显示出更频繁的左右切换.
- 前上皮质的横向性变化与L2熟练程度有负相关性.
结论:
- 获得L2的年龄显著影响皮层-皮层dFC模式.
- 双语,特别是早期学习,与大脑网络动态和功能横向性的改变有关.
- 研究结果提供了对双语和认知灵活性背后的神经机制的见解.

The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...
Higher Mental Functions of the Brain: Language
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...
