概括
双重任务,即同时执行认知和运动任务,显示出显著的性能差异,特别是在执行抑制方面. 步行速度不会影响健康成年人的认知任务表现.
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
- 人类因素 人类因素
背景情况:
- 双任务效应 (DTE) 检查在同时执行两个任务时的性能,通常是认知和运动.
- DTE影响日常活动,并已在健康个体和患者中进行研究.
- 在现实世界的双重任务场景中,执行抑制技能和决策方面至关重要.
研究的目的:
- 复制之前的双重任务效应 (DTE),包括执行抑制.
- 扩大关于双重任务期间决策的证据.
- 为了研究行走对需要执行抑制的认知任务的影响.
主要方法:
- 50名健康的年轻人完成了停止信号任务和两个博任务 (损失厌恶,风险厌恶).
- 任务在坐着和走路时以三个不同的跑步机速度 (正常,缓慢,快速) 执行.
- 分析了姿势对齐 (节奏,步态周期长度,姿势阶段).
主要成果:
- 在单任务和双任务性能之间发现了显著的差异,具有很高的个体变化.
- 步行速度没有显著影响任何认知任务的表现.

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...

Decision Making

Decision-making is a fundamental cognitive process that involves evaluating alternatives and selecting among them. This process can range from simple choices, such as deciding what to wear, to complex decisions, like choosing a major in college or a career path. The complexity of the decision often dictates the approach we use, which can be broadly categorized into two types: automatic and controlled decision-making.
Automatic decision-making is fast, intuitive, and relies on gut feelings...
