Cause and Effect01:53

Cause and Effect

10.9K
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 Biases01:31

Confirmation Biases

5.5K
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?

False Memories01:18

False Memories

89
False memories represent a cognitive distortion in which individuals recall events that did not happen, or remember them in an altered form. This phenomenon highlights the brain's constructive nature in processing and recalling memories, emphasizing that memory is not a perfect representation of past events but rather a dynamic reconstruction influenced by various factors.
One primary source of false memories is misattribution, where individuals incorrectly associate external information...

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...

Perceptual Constancy01:12

Perceptual Constancy

394
Perceptual constancy is the ability to recognize that objects remain consistent and unchanged even when their appearance varies due to changes in sensory input. There are four main types of perceptual constancy: size constancy, shape constancy, color constancy, and brightness constancy.
Size constancy is the recognition that an object remains the same size, even when its image on the retina changes. For instance, a bus is perceived to be large enough to carry people, even if it looks tiny from...

Hindsight Biases01:12

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?

Summary
This summary is machine-generated.

Engaging in a secondary task reduces the Illusory Truth Effect (ITE), making people less likely to believe repeated information. Higher accuracy on the secondary task correlated with a stronger ITE, suggesting cognitive load impacts belief formation.

Area of Science:

  • Cognitive Psychology
  • Social Psychology

Background:

  • The Illusory Truth Effect (ITE) describes the tendency to believe repeated information.
  • Semantic processing is crucial for the ITE.
  • Everyday multitasking may influence information processing and belief.

Purpose of the Study:

  • To investigate how concurrent secondary tasks affect the Illusory Truth Effect.
  • To determine if cognitive load from multitasking modulates belief in repeated statements.

Main Methods:

  • Three experiments adapted the ITE paradigm.
  • Participants performed a secondary task (e.g., vowel counting) during statement encoding and/or testing.
  • Accuracy on the secondary task was measured.

Main Results:

  • The ITE was significantly larger when participants were not engaged in a secondary task.
  • Higher accuracy on the secondary task was associated with a larger ITE.
  • Concurrent cognitive load appears to reduce the impact of repetition on belief.

Conclusions:

  • Engaging in secondary tasks can diminish the Illusory Truth Effect.
  • Cognitive load is a key factor influencing susceptibility to the ITE.
  • Further research into secondary task effects on belief formation is warranted.
