The Anchoring-and-Adjustment Heuristic01:25

The Anchoring-and-Adjustment Heuristic

7.2K
In order to make good decisions, we use our knowledge and our reasoning. Often, this knowledge and reasoning is sound and solid. However, sometimes, we are swayed by biases or by others manipulating a situation. For example, let’s say you and three friends wanted to rent a house and had a combined target budget of $1,600. The realtor shows you only very run-down houses for $1,600 and then shows you a very nice house for $2,000. Might you ask each person to pay more in rent to get the...

Fundamental Attribution Error

12.8K
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...

Accuracy and Errors in Hypothesis Testing01:13

Accuracy and Errors in Hypothesis Testing

193
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%...

Self-Presentation: Self-Monitoring and Self-Handicapping

People can go to great lengths to protect their self-image and present themselves in ways that they want others to see them. Sociologist Erving Goffman presented the idea that a person is like an actor on a stage. Calling his theory dramaturgy, Goffman believed that we use “impression management” to present ourselves to others as we hope to be perceived. Each situation is a new scene, and individuals perform different roles depending on who is present (Goffman, 1959). Think about...

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?

Types of Errors: Detection and Minimization01:12

Types of Errors: Detection and Minimization

1.6K
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...

Area of Science:

  • Cognitive Neuroscience
  • Human Psychology

Background:

  • Errors prompt adjustments to improve future performance within a task.
  • Limited research explores if these post-error adjustments are task-general or task-specific.

Purpose of the Study:

  • Investigate the task-general versus task-specific nature of post-error adjustments.
  • Examine the temporal dynamics and neural correlates of these adjustments.
  • Determine the role of error awareness in modulating post-error control mechanisms.

Main Methods:

  • Utilized a psychological refractory period paradigm involving two tasks (Task 1 and Task 2).
  • Collected behavioral data (reaction times, accuracy) and electrophysiological data (EEG).
  • Varied stimulus onset asynchrony (SOA) between tasks to probe temporal dynamics.

Main Results:

  • Behavioral adjustments were task-general at short SOAs and task-specific at long SOAs.
  • EEG data revealed short-lived task-general adjustments and long-lasting task-specific adjustments.
  • Error awareness enhanced subsequent performance and sensory processing specifically in the task where the error occurred.

Conclusions:

  • Post-error adjustments involve simultaneous transient, task-general interference and long-lasting, task-specific control.
  • Error awareness is critical in determining the type and duration of post-error control mechanisms.
  • Central cognitive resources contribute to the task specificity of post-error adjustments.
