Focusing of Light in the Eye01:16

Focusing of Light in the Eye

Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...
Blinding01:11

Blinding

Blinding is a commonly used method of not telling participants which treatment a subject is receiving. Blinding is a critical part of a randomized control trial or RCT. It reduces the bias that affects the results. In an RCT, blinding is used in the form of a placebo. A placebo effect occurs when untreated subjects falsely believe they have received the treatment and report improved symptoms. A placebo or a dummy treatment is administered to subjects to negate the bias caused by such an effect.
Hindsight Biases01:12

Hindsight Biases

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?
Blind Procedures02:07

Blind Procedures

Ideally, the people who observe and record the children’s behavior are unaware of who was assigned to the experimental or control group, in order to control for experimenter bias. Experimenter bias refers to the possibility that a researcher’s expectations might skew the results of the study. Remember, conducting an experiment requires a lot of planning, and the people involved in the research project have a vested interest in supporting their hypotheses. If the observers knew which child was...
Fundamental Attribution Error01:14

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...
Types of Errors: Detection and Minimization01:12

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...

Summary
This summary is machine-generated.

Following errors, cognitive performance often declines. This study found that participants exhibited worse target detection after making errors in a flanker task, supporting theories of decreased post-error performance.

Area of Science:

  • Cognitive Psychology
  • Neuroscience

Background:

  • Behavioral changes commonly follow errors, but post-error accuracy changes are not fully understood.
  • Error monitoring research often focuses on functional accounts, with less attention to non-functional explanations.

Purpose of the Study:

  • To investigate accuracy changes following errors.
  • To differentiate between bottleneck and orienting accounts of post-error adjustments.

Main Methods:

  • A flanker task was combined with a Rapid Serial Visual Presentation (RSVP) task.
  • Participants performed the RSVP task with and without immediate feedback on the flanker task.
  • Irrelevant red signals were presented to test bottleneck vs. orienting accounts.

Main Results:

  • Worse target detection was observed after errors in the flanker task, regardless of feedback.
  • Decreased target detection occurred after irrelevant red signals, supporting the bottleneck account.

Conclusions:

  • Findings support non-functional accounts of error monitoring, predicting decreased post-error performance.
  • The results suggest a bottleneck mechanism contributes to reduced performance after errors.
