概括
儿童和成年人在行走时使用微小的触觉力进行沟通. 成年人在指导孩子时更为严格,
科学领域:
- 人与计算机的交互
- 发展心理学
- 生物力学
背景情况:
- 触觉互动对于移动过程中的人际协调至关重要.
- 对成年人的触觉指导的研究是广泛的,但对儿童的互动知之甚少.
- 了解儿童和成年人的触觉协调对于开发辅助技术至关重要.
研究的目的:
- 研究儿童和成年人的触觉导向运动.
- 分析触觉线索如何促进不同年龄段的步行协调.
- 在运动过程中识别触觉相互作用的年龄相关差异.
主要方法:
- 检查了11对 (成人-成人,儿童-儿童,成人-儿童) 携手并肩行走.
- 一个参与者带领, 而另一个, 蒙上眼睛, 追随.
- 在直线和曲线路径中记录和分析上肢肌肉电肌图,动力学和触觉相互作用力.
主要成果:
- 所有的二极管都表现出很小的相互作用力 (约. 3 N),表明沟通而不是机械的角色.
- 步行启动显示了合适的相互作用,前骨活动有助于手臂运动,特别是在成年人-儿童对中.
- 方向特定的力和臂高度调整有效地传达了跨年曲线运动中的触觉线索.
- 与其他成年人相比,在指导儿童时,成年人上肢依从性降低.
- 无论他们的角色 (领导者/追随者) 是什么,孩子们都表现出更多的服从.
结论:
- 触觉相互作用主要是作为沟通的线索.
- 成年人优先考虑控制和稳定, 而儿童则表现出更可变,
- 与年龄相关的遵守差异突出显示了儿童和成年人在触觉引导的移动过程中的不同交互策略.

The history of therapeutic communication can be traced back to Florence Nightingale, who emphasized the importance of developing trusting relationships with patients. She taught that the presence of nurses with patients results in therapeutic healing.
Therapeutic communication is not the same as social interaction. Social interaction has no goal or purpose and consists of casual information sharing, whereas therapeutic communication has a plan or purpose for the conversation. Therapeutic...

01:18Hierarchy of Motor Control
The hierarchy of motor control refers to the different levels of organization and processing involved in controlling movement in the body. These levels range from higher cortical areas involved in planning and decision-making to lower spinal cord reflexes that respond automatically to external stimuli.
