概括

婴儿和照顾者根据直立与非直立运动的成本调整他们的运动选择. 他们考虑了起步姿势和距离等因素,证明了对运动效率的敏感性.

科学领域:

发展心理学发展心理学
发动机控制器的控制器
人类的机动运动

背景情况:

运动涉及决策受到不同姿势的能量和稳定性成本的影响.
了解婴儿对这些成本的敏感性对于发展洞察至关重要.

研究的目的:

调查婴儿及其照顾者是否对直立和非直立运动的直接成本表现出敏感性.
分析起始姿势,运动技巧和行驶距离等因素如何影响运动决策.

主要方法:

与24名爬行和24名行走的婴儿与他们的护理人员进行了比较,这是一项涉及集群和分散的玩具的任务.
根据初始姿势和行程距离,观察到关于直立与非直立运动的决策.

主要成果:

所有组都对运动成本表现出敏感性,根据起始姿势和行驶距离调整运动.
步行者/护理人员只有在开始坐着和短距离时才能移动非直立;否则,他们会步行.
爬行物只在起立和短距离开始时才能直立;否则,它们会爬行.

结论:

婴儿和成年人一样,对与不同形式的运动相关的动态成本很敏感.
基于直接的环境和姿势因素优化运动决策,即使在幼儿中也是如此.

Major Somatic Sensory Pathways

Major Somatic Sensory Pathways

Sensory impulses related to touch, pressure, vibration, and proprioception from various body parts, such as the limbs, trunk, neck, and posterior head, travel to the cerebral cortex through the posterior column-medial lemniscus pathway. The pathway’s name derives from the two white-matter tracts that convey the impulses: the spinal cord's posterior column and the brainstem's medial lemniscus. First-order sensory neurons extend their axons into the spinal cord, forming the...
