概括
错误消极性 (Ne) 和类似Ne的波 (Nc) 可能发生在正确的响应上,这是由于无法预测的响应执行. 纠正这些部分错误可以消除Ne/Nc,这表明执行精度是关键.
科学领域:
- 神经科学是一个神经科学.
- 认知科学 认知科学
- 电子生理学 电子生理学
背景情况:
- 错误负性 (Ne) 是一种电生理学标记,通常在错误之后观察到.
- 一个相关的波,Ne-like波 (Nc),在正确的试验中出现,但它的起源仍在争论中.
- 正确反应之前的下值肌肉激活表明了潜在的执行错误.
研究的目的:
- 研究响应执行精度在生成Ne/Nc.中的作用.
- 测试假设,正确试验中的Ne/Nc反映了响应执行中的不确定性.
- 区分响应选择中的错误和响应执行中的错误.
主要方法:
- 在健康受试者中使用了脑电图 (EEG) 和心电图 (EMG).
- 分析的重点是正确和部分正确反应期间Ne/Nc的存在和幅度.
- 拉普拉西安转换应用于EEG数据以增强空间分辨率.
主要成果:
- 部分正确的反应,以小于值的EMG活性来表示,引起了显著的Ne.
- 在这些部分错误之后的正确答案显示没有可识别的Nc.
- 这表明正确试验中的Ne/Nc与响应执行的可预测性有关.
结论:
- 正确试验的Ne/Nc可能反映了行动监控系统对不可预测的响应执行的反应.
- 在纠正部分执行错误后没有Nc,这支持了这一解释.
- 响应执行的准确性,而不仅仅是响应选择,是错误相关潜力的关键因素.

Fundamental Attribution Error
12.9K
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...

Regression Toward the Mean
6.3K
Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...

Hindsight Biases
3.4K
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?

Errors In Hypothesis Tests

When performing a hypothesis test, there are four possible outcomes depending on the actual truth (or falseness) of the null hypothesis and the decision to reject or not.

Punishment
179
Negative reinforcement and punishment are often confused but serve distinct functions in behavior modification. Reinforcement, whether positive or negative, increases the likelihood of a desired behavior, while punishment decreases it.
Punishment can be positive or negative. Positive punishment involves adding an undesirable stimulus, such as scolding, to decrease a behavior. Negative punishment involves removing a desirable stimulus, such as taking away a favorite toy, to decrease behavior....

Rational Emotive Behavior Therapy
50
Cognitive-behavioral therapies (CBTs) are grounded in the belief that our thoughts profoundly influence our emotions and actions. Advocates of CBT emphasize three core assumptions: first, that cognitions are identifiable and measurable; second, that they are central to psychological functioning; and third, that irrational or maladaptive beliefs can be replaced with rational and adaptive ones. This transformative approach to therapy has paved the way for specific models such as Albert...
