概括
年长的成年人在较慢的速度上更普遍地概括走路模式,而年轻的成年人在更快的速度上更普遍地概括. 这表明舒适的步行速度可以在不同环境中增强运动模式的泛化.
科学领域:
- 神经科学是一个神经科学.
- 发动机控制器的控制器
- 人类的衰老 人类的衰老
背景情况:
- 与年轻人相比,老年人通常在不同的运动需求中表现出更大的行走模式的概括性.
- 之前的研究使用了老年人舒适的步行速度,从而打开了不同速度的年龄特定概括的问题.
研究的目的:
- 为了研究健康的衰老和步行速度之间的相互作用,关于在分带跑步机上学习的运动模式的概括.
- 为了确定年轻人是否以更快的速度更普遍,而老年人则以更慢的速度更普遍.
主要方法:
- 年轻 (<30岁) 和年长 (65岁以上) 的成年人适应了他们的步态,在分带跑步机上以较慢或更快的步行速度行走.
- 在随后的地面行走过程中,通过测量步态后果来评估概括性.
主要成果:
- 在步行模式的概括中观察到年龄和步行速度之间的显著相互作用.
- 老年人在适应较慢的速度时表现出更大的概括性,而年轻人在更快的速度时表现出更大的概括性.
结论:
- 运动学习期间的步行速度以特定年龄的方式影响了步行模式的概括.
- 舒适的步行速度似乎促进了新获得的运动模式在不同环境中的更大泛化.

01:26Higher Mental Functions of Brain: Learning and Memory
2.2K
Memory is one of the most vital higher mental functions of the brain. Memory is closely related to learning because it enables us to retain information and experiences from our past to use them in our present life. It also helps us to remember facts, events, and skills, such as riding a bike or swimming. There are two types of memory — declarative memory, which involves memorizing facts or events, and procedural memory, which enables us to remember how to do something like writing or...

Implicit memories, also known as non-declarative memories, are long-term memories that function outside of conscious awareness. These memories influence behavior and skills without explicit knowledge. This type of memory is evident in tasks like playing tennis, snowboarding, and texting. Implicit memory has three subsystems: procedural memory, conditioning, and priming. This type of memory is essential in various activities, from everyday tasks to specialized skills.
