概括
自发的内在协调,非故意的协调行为,在行走过程中不如发声,因为行走的注意力要求更高. 认知负载进一步降低了这些周期性任务中的协调稳定性.
科学领域:
- 认知神经科学 认知神经科学
- 发动机控制器的控制器
- 人类行为人类行为.
背景情况:
- 自发的内在人际协调涉及个人内周期性行为的无意同步.
- 根据复杂性和注意力要求,任务之间的协调可能会有所不同.
- 以前的研究表明,步行可能会比其他周期性运动带来更高的注意力成本.
研究的目的:
- 为了比较手指敲击和走路与手指敲击和发声之间的协调稳定性.
- 调查并发性认知负载对这些周期性任务的协调的影响.
- 为了确定行走的复杂性是否会影响人内协调的稳定性.
主要方法:
- 两项实验评估了协调稳定性,使用同步周期性任务 (与步行或发声一起敲击) 之间的相连贯性.
- 任务单独执行 (单一任务) 或与认知任务 (双重任务) 同步执行.
- 认知任务包括在敲击-走路过程中倒计时,在敲击-发声过程中视觉模式匹配.
主要成果:
- 当任务同时执行而不是单独执行时,自发的人内协调性更高.
- 在同步的认知负载下,协调稳定性显著下降.
- 与手指敲打和发声相比,在手指敲打和走路之间,协调稳定性较低.
结论:
- 自发的内在协调对与定期活动相关的注意力成本敏感.
- 步行被认为更复杂,与发声相比,与其他任务的协调稳定性较低.
- 注意力负荷是影响人内协调稳定的关键因素.

Reason and Intuition
6.3K
The human brain processes information for decision-making using one of two routes: an intuitive system and a rational system (Epstein, 1994; popularized by Kahneman, 2011 as System 1 and System 2, respectively). The intuitive system is quick, impulsive, and operates with minimal effort, relying on emotions or habits to provide cues for what to do next, while the rational system is logical, analytical, deliberate, and methodical. Research in neuropsychology suggests that the...

Cognitive Learning

Cognitive learning is based on purposive behavior, incidental learning, and insight learning.
E. C. Tolman's theory of purposive behavior emphasizes that much behavior is goal-directed. He argued that to understand behavior, we must look at the entire sequence of actions leading to a goal. For instance, high school students study hard, not just due to past reinforcement but also to achieve the goal of getting into a good college.

High-Level and Low-Level Awareness

Controlled processes in human consciousness represent high-alert mental states where individuals deliberately focus their attention on achieving specific goals. Controlled processes can be seen in situations like mastering new technology, where a person might become so absorbed that they ignore surrounding distractions. Such processes involve selective attention, requiring one to concentrate on particular elements of experience while disregarding others. These are governed by executive...

Nonconscious Mimicry

Nonconscious mimicry occurs when individuals alter their mannerisms to match the behaviors and expressions of those nearby, without intention.

Social Facilitation
31.6K
Not all intergroup interactions lead to negative outcomes. Sometimes, being in a group situation can improve performance. Social facilitation occurs when an individual performs better when an audience is watching than when the individual performs the behavior alone. This typically occurs when people are performing a task for which they are skilled.

Cognitivism

Cognitive psychology emerged as a significant field in the mid-20th century. It focused on understanding humans' internal mental processes. This approach emphasizes how people perceive, remember, think, and solve problems—elements critical to human cognition.
