概括
短期使用工具并不会显著改变身体结构或跨年龄组的感知到达距离. 短暂的暴露可能不足以产生持久的感觉运动适应,而不是更长时间的训练.
科学领域:
- 神经科学是一个神经科学.
- 认知心理学 认知心理学
- 人类寿命发展 人类寿命发展
背景情况:
- 工具的使用可以融入身体的表现,作为身体的延伸.
- 这种结合取决于年龄,受感觉运动整合的发展和下降的影响.
- 了解身体结构中的与年龄相关的可塑性对于人机交互和康复至关重要.
研究的目的:
- 调查年龄如何影响身体图形塑性和短期工具使用训练后感知到达距离.
- 检查近距离和远距离空间操纵对这些适应的影响.
- 确定工具使用培训是否会导致触觉距离感知的显著变化,并达到整个寿命的估计.
主要方法:
- 84名参与者 (12至80岁) 接受了近距离和远距离空间的工具使用范式.
- 在前臂的触觉距离判断评估的身体图形变化.
- 在训练前和训练后执行了达到距离估计任务.
主要成果:
- 参与者表现出前臂触觉距离估计减少,但工具使用训练没有改变这些判断.
- 在近距离或远距离空间使用工具训练后,没有观察到感知到达距离的显著变化.
- 这些影响在所有测试年龄组中一致.
结论:
- 短期工具使用培训不会显著改变触觉距离感知或跨年龄组感知到达距离.
- 短暂的工具使用暴露似乎不足以诱导持久的感觉运动适应.
- 工具与身体表现的基本整合可能会在整个生命周期内保持稳定,尽管与年龄相关的熟练程度差异.

A schema is a mental construct consisting of a cluster or collection of related concepts (Bartlett, 1932). There are many different types of schemata, and they all have one thing in common: schemata are a method of organizing information that allows the brain to work more efficiently. When a schema is activated, the brain makes immediate assumptions about the person or object being observed.

2.0K
The sensorimotor stage, the initial phase of Jean Piaget's theory of cognitive development, spans the first two years of a child's life. During this period, infants actively engage with their surroundings, building cognitive awareness through direct interaction with the world. This interaction is primarily based on sensory perception and motor actions, allowing infants to gradually understand basic physical properties and predict how objects interact within their environment.

01:30Impact of Schemas
227
Schemas are cognitive structures that provide a framework for interpreting and organizing social information. They help individuals navigate complex environments by offering expectations about people, events, and behaviors. Schemas influence attention, encoding, and retrieval processes, thereby shaping the entire trajectory of information processing in social contexts.Attention and Cognitive LoadDuring initial attention, schemas function as filters that prioritize schema-consistent information,...

01:25Piaget's Theory of Cognitive Development from Childhood into Adulthood
1.9K
Jean Piaget's theory of cognitive development emphasizes the role of thinking in a child's learning process, suggesting that children are naturally curious about their environment. His approach to development is discontinuous, proposing that cognitive abilities progress through distinct stages, each with unique characteristics. Central to Piaget's theory is schemata—mental structures that allow individuals to understand and interpret the world.
