Types of Errors: Detection and Minimization

Types of Errors: Detection and Minimization

Error is the deviation of the obtained result from the true, expected value or the estimated central value. Errors are expressed in absolute or relative terms.
Absolute error in a measurement is the numerical difference from the true or central value. Relative error is the ratio between absolute error and the true or central value, expressed as a percentage.
Errors can be classified by source, magnitude, and sign. There are three types of errors: systematic, random, and gross.
Systematic or...

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 called the fundamental attribution...

Detection of Gross Error: The Q Test

Detection of Gross Error: The Q Test

When one or more data points appear far from the rest of the data, there is a need to determine whether they are outliers and whether they should be eliminated from the data set to ensure an accurate representation of the measured value. In many cases, outliers arise from gross errors (or human errors) and do not accurately reflect the underlying phenomenon. In some cases, however, these apparent outliers reflect true phenomenological differences. In these cases, we can use statistical methods...

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...

Local Attraction

Local Attraction

Local attraction refers to disturbances in compass readings caused by magnetic influences from nearby objects such as metal fences, buried pipes, vehicles, buildings, power lines, or natural iron ore deposits. Small items like wristwatches, steel tools, or belt buckles can also interfere with the compass by creating local magnetic fields that distort the Earth's natural magnetic field. These distortions lead to inaccurate readings, posing navigation and land surveying challenges.Local...

Errors and Mistakes in Surveying

Errors and Mistakes in Surveying

Errors and mistakes in surveying refer to inaccuracies in measurements and data recording. The errors are deviations from the actual value caused by human sensory limitations, equipment flaws, or environmental effects. These errors are typically unintentional and can result from the inherent imperfections in the instruments used, atmospheric conditions, or the observer’s inability to perceive exact measurements. On the other hand, mistakes are caused by the surveyor's lack of attention,...

Summary

This summary is machine-generated.

Error correction involves distinct brain activity patterns. The error-related negativity (ERN) is stronger and originates from different brain regions for corrected versus uncorrected errors, highlighting cognitive control processes.

Area of Science:

Neuroscience
Cognitive Psychology
Brain Imaging

Background:

Understanding error processing is crucial for cognitive control research.
The error-related negativity (ERN) is a well-documented electrophysiological marker of error detection.

Purpose of the Study:

To investigate the neural sources of ERN in corrected versus uncorrected errors.
To differentiate the brain mechanisms underlying error monitoring and response correction.

Main Methods:

Participants performed a flanker task with corrected and uncorrected errors.
Electroencephalography (EEG) was used to record brain activity.
Low-resolution electromagnetic tomography (LORETA) was applied for source localization of the ERN.

Main Results:

The ERN was stronger and occurred earlier for corrected errors compared to uncorrected errors.
ERN neural sources differed between error types: corrected errors involved anterior cingulate (BA 24) and pre-supplementary motor area (BA 6), while uncorrected errors primarily involved the anterior cingulate (BA 24).

Conclusions:

The anterior cingulate cortex is a primary source of the ERN.
The pre-supplementary motor area contributes to ERN generation when response correction is actively initiated.
