概括
明确的指令可能会阻碍电机适应转移. 与没有信息相比,提供准确信息提高了业绩,但错误信息没有显著影响结果.
科学领域:
- 运动控制和学习.
- 认知心理学 认知心理学
- 人与计算机的互动.
背景情况:
- 摩托适应对于调整运动以适应新动态至关重要.
- 明确指令在运动适应转移中的作用仍在争论中.
- 了解明确信息如何影响学习对于技能获得至关重要.
研究的目的:
- 调查明确指令对电机适应转移的影响.
- 在准确信息,错误信息和没有信息条件下比较任务性能.
- 要确定明确的知识是否会影响适应变化的运动动态的能力.
主要方法:
- 93名健康的成年人进行了基于光标的运动适应任务,旋转60度.
- 群体收到关于轮换的准确信息 (AG),错误信息 (MG) 或没有信息 (NG).
- 一个转移任务逐渐将旋转增加到80°以评估无需明确通知的适应性.
主要成果:
- 与没有信息组 (NG) 相比,准确信息组 (AG) 在转移任务中的平均误差距明显较低.
- 与没有信息组 (NG) 相比,错误信息 (MG) 并没有导致显著不同的表现.

01:23Muscles that Move the Leg
The movement of the legs is facilitated by numerous muscles located within the anterior, medial, and posterior compartments of the thigh.
Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed to...

01:28Muscles of the Leg that Move the Foot and Toes
The human leg comprises an intricate system of muscles that facilitate the movement of feet and toes. Within this system, the muscles are categorized into the anterior, lateral, and posterior compartments, each with a unique set of muscles carrying out specific functions.
Anterior Compartment
The anterior compartment includes muscles that contribute to the dorsiflexion of the foot. This compartment houses the tibialis anterior, extensor hallucis longus, and extensor digitorum longus muscles.
