概括
不同的刺激操纵产生不同的信心模式. 刺激的可靠性创建了一个双增长模式,而边界距离创建了经典的折叠X模式,与人工神经网络行为不同.
科学领域:
- 认知心理学 认知心理学
- 计算神经科学是一种计算神经科学.
背景情况:
- 折叠X模式是信心的关键指标,更轻松的条件增加了对正确试验的信心,但减少了对错误的信心.
- 像双增幅模式 (简单的条件增加了对正确和错误试验的信心) 这样的违规行为已被观察到,但潜在的刺激操纵仍然不清楚.
研究的目的:
- 为了调查刺激可靠性或边界距离操纵是否差异产生折叠X和双倍增长的信心模式.
- 将人类的信心判断与人工神经网络 (ANN) 响应进行比较.
主要方法:
- 两个实验 (N=78) 涉及使用Gabor补丁或移动点的定向判断任务.
- 刺激操纵侧重于刺激的可靠性或边界距离.
- 人工神经网络也接受了相同任务的训练.
主要成果:
- 边界距离操纵主要影响准确性,而刺激可靠性操纵主要影响信心.
- 边界距离操纵产生了折叠X模式,而刺激可靠性操纵产生了双增幅模式.
- 与人类参与者不同的是,ANN在两种操纵中都显示了折叠X模式.
结论:
- 不同的刺激操纵对信心签名有不同的影响.
- 人类的信心受到标准ANN无法捕捉的机制的影响.
- 反应时间部分反映了信心,但作为代理的局限性.

Cause and Effect
12.6K
While variables are sometimes correlated because one does cause the other, it could also be that some other factor, a confounding variable, is actually causing the systematic movement in our variables of interest. For instance, as sales in ice cream increase, so does the overall rate of crime. Is it possible that indulging in your favorite flavor of ice cream could send you on a crime spree? Or, after committing crime do you think you might decide to treat yourself to a cone?

Confirmation Biases
8.4K
The confirmation bias is the tendency to focus on information that confirms our existing beliefs and ignore information that is inconsistent with our expectations. For example, if you think that your professor is not very nice, you notice all of the instances of rude behavior exhibited by the professor while ignoring the countless pleasant interactions he is involved in on a daily basis. Have you ever fallen prey to the confirmation bias, either as the source or target of such bias?

Interpretation of Confidence Intervals
10.2K
A confidence interval is a better estimate of the population than a point estimate, as it uses a range of values from a sample instead of a single value.
Confidence intervals have confidence coefficients that are crucial for their interpretation. The most common confidence coefficients are 0.90, 0.95, and 0.99, which can be written as percentages–90%, 95%, and 99%, respectively.
Suppose a person calculates a confidence interval with a confidence coefficient of 0.95. In that case, they can...

Uncertainty: Confidence Intervals
11.9K
The confidence interval is the range of values around the mean that contains the true mean. It is expressed as a probability percentage. The interpretation of a 95% confidence interval, for instance, is that the statistician is 95% confident that the true mean falls within the interval. The upper and lower limits of this range are known as confidence limits. The confidence limits for the true mean are estimated from the sample's mean, the standard deviation, and the statistical factor...

Confidence Intervals
10.9K
An unbiased point estimate is often insufficient to predict a population estimate, such as population mean or population proportion. In this scenario, a confidence interval is used. A confidence interval is an estimate similar to a sample proportion. However, unlike the point estimate which is a single value, the confidence interval contains a range of values. These values have lower and upper limits, known as confidence limits, and can be designated as L1 and L2, respectively.

Reliability and Validity
14.2K
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.
