概括
当出现多个错误信号时,人类可以选择性地减少传感运动适应. 错误的任务相关性影响运动学习,这表明有偏见的竞争机制优先考虑与目标相关的信息.
科学领域:
- 神经科学是一个神经科学.
- 发动机控制器的控制器
- 人类的适应能力
背景情况:
- 对错误的感觉运动适应通常被认为是自动的.
- 人们还没有完全理解大脑选择性地过或优先考虑错误信号的能力.
研究的目的:
- 根据错误信号的任务相关性,研究人类是否可以选择性地减弱感官运动适应.
- 探索当面对多个同时发生的干扰时适应的稳定性.
主要方法:
- 参与者执行平面达到各种目标 (弧,条,点).
- 视觉运动干扰,包括范围 (增益) 和方向 (旋转) 错误,被单独同时应用.
- 测量了对任务无关和任务相关错误的适应.
主要成果:
- 适应甚至发生在单独呈现时与任务无关的扰动.
- 当与任务相关的干扰同时发生时,对干扰的适应显著减弱.
- 这种减弱并不是由于无法适应组合扰动.
结论:
- 当多个错误信号存在时,传感运动系统可以选择调整学习.
- 一个有偏见的竞争机制,优先考虑由于处理能力有限而与目标相关的错误,可能会解释这些发现.
- 运动学习受感官反对任务目标的感知相关性的影响.

Hindsight Biases
Hindsight bias leads you to believe that the event you just experienced was predictable, even though it really wasn’t. In other words, you knew all along that things would turn out the way they did. Can you relate this to the phrase "Hindsight is 20/20" now?
Fundamental Attribution Error
According to some social psychologists, people tend to overemphasize internal factors as explanations—or attributions—for the behavior of other people. They tend to assume that the behavior of another person is a trait of that person, and to underestimate the power of the situation on the behavior of others. They tend to fail to recognize when the behavior of another is due to situational variables, and thus to the person’s state. This erroneous assumption is called the fundamental attribution...
Survival Tree
Survival trees are a non-parametric method used in survival analysis to model the relationship between a set of covariates and the time until an event of interest occurs, often referred to as the "time-to-event" or "survival time." This method is particularly useful when dealing with censored data, where the event has not occurred for some individuals by the end of the study period, or when the exact time of the event is unknown.

Unrealistic Optimism Bias
Unrealistic optimism bias is the tendency to overestimate the likelihood of positive outcomes. This cognitive bias makes individuals believe they are less likely to experience failures, setbacks, or risks and more likely to succeed than others. For example, people may assume they are less prone to health issues, accidents, or financial struggles than their peers, even when they share similar risk factors.One key component of this bias is the above-average effect, where individuals perceive...
Motivational Bias
Cognitive bias results from limitations in thinking and information processing, leading to systematic errors in judgment. Conversely, motivational bias stems from personal desires or emotions, causing distortions in perception to align with self-interest. Motivational bias influences how individuals perceive and attribute causes to events, often shaped by personal needs, goals, and self-esteem preservation. This bias can distort judgment, leading to inaccurate assessments of success, failure,...
