概括
学习运动结构的速度更快,更多的练习重复. 视觉旋转的八次重复最好地改善了在达到任务中适应新扰动的适应能力,相比较少的重复或对照组.
科学领域:
- 发动机控制器 发动机控制器
- 认知神经科学是一种认知神经科学.
- 人类的运动学习.
背景情况:
- 结构性学习涉及从可变扰动中概括运动结构.
- 以前的研究表明,可变扰动增强了适应新变化的能力.
- 对干扰的重复暴露可能会限制结构性学习的好处.
研究的目的:
- 调查扰乱连续重复的数量如何影响结构学习.
- 为了确定是否增加重复增强适应新视觉运动扰乱的适应.
主要方法:
- 中心到达任务与视觉反旋转.
- 三个训练组接受了2,4或8次±90度旋转的重复.
- 一个在零场中训练的对照组.
- 在随后的固定旋转测试中评估的适应性.

Higher 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...

Observational Learning
1.5K
Albert Bandura's observational learning, also known as imitation or modeling, occurs when a person observes and imitates another's behavior. It is a quicker process than operant conditioning. A well-known example is the Bobo doll study, where children who saw an adult acting aggressively towards the doll were more likely to act aggressively when left alone, compared to those who observed a nonaggressive adult. Many psychologists view observational learning as a form of latent learning...
