Errors In Hypothesis Tests

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.

Accuracy and Errors in Hypothesis Testing

Accuracy and Errors in Hypothesis Testing

Hypothesis testing is a fundamental statistical tool that begins with the assumption that the null hypothesis H0 is true. During this process, two types of errors can occur: Type I and Type II. A Type I error refers to the incorrect rejection of a true null hypothesis, while a Type II error involves the failure to reject a false null hypothesis.
In hypothesis testing, the probability of making a Type I error, denoted as α, is commonly set at 0.05. This significance level indicates a 5%...

Systematic Error: Methodological and Sampling Errors

Systematic Error: Methodological and Sampling Errors

In the case of systematic errors, the sources can be identified, and the errors can be subsequently minimized by addressing these sources. According to the source, systematic errors can be divided into sampling, instrumental, methodological, and personal errors.
Sampling errors originate from improper sampling methods or the wrong sample population. These errors can be minimized by refining the sampling strategy. Defective instruments or faulty calibrations are the sources of instrumental...

Fundamental Attribution Error

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...

Random Error

Random Error

Random or indeterminate errors originate from various uncontrollable variables, such as variations in environmental conditions, instrument imperfections, or the inherent variability of the phenomena being measured. Usually, these errors cannot be predicted, estimated, or characterized because their direction and magnitude often vary in magnitude and direction even during consecutive measurements. As a result, they are difficult to eliminate. However, the aggregate effect of these errors can be...

Margin of Error

Margin of Error

The margin of error is also called the maximum error of an estimate. The margin of error is the maximum possible or expected difference between the observed sample parameter value and the actual population parameter value. For proportion, it is the maximum difference between the value of sample proportion obtained from the data and the true value of population proportion. As the true value of the population parameter is not known, the margin of error is calculated using the sample statistic.

Summary

Making errors slows cognitive processing, as cognitive resources are depleted. This performance reduction decays over trials, with early attention (N1) and higher-order processing (P3) changes observed after errors.

Area of Science:

Cognitive Neuroscience
Psychology

Background:

The bottleneck account suggests cognitive resources deplete after errors, delaying subsequent processing.
Understanding post-error cognitive adjustments is crucial for explaining performance decrements.

Purpose of the Study:

To investigate the temporal dynamics of cognitive resource depletion after errors.
To examine the neural correlates of post-error slowing using event-related potentials (ERPs).

Main Methods:

A novel speeded-choice task was employed.
Behavioral measures and event-related potential (ERP) components (N1, P3) were recorded for five trials post-response.
Responses were categorized as either erroneous or correct.

Main Results:

Participants exhibited slower and less accurate performance immediately following an error.
This performance decrement gradually decayed over subsequent trials.
Distinct ERP differences were observed: the P3 component difference diminished quickly, while the N1 component difference persisted longer.

Conclusions:

Results support the bottleneck account of post-error slowing.
Post-error adjustments involve both early attentional (N1) and higher-order processing (P3) changes.
The persistence of N1 differences suggests sustained attentional modulation after errors.
