Correlations02:20

Correlations

36.5K
Correlation means that there is a relationship between two or more variables (such as ice cream consumption and crime), but this relationship does not necessarily imply cause and effect. When two variables are correlated, it simply means that as one variable changes, so does the other. We can measure correlation by calculating a statistic known as a correlation coefficient. A correlation coefficient is a number from -1 to +1 that indicates the strength and direction of the relationship between...

Correlation and Causation

42.9K
Statistical tests can calculate whether there is a relationship, or correlation, between independent and dependent variables. An indirect relationship of the variables signifies a correlation, while a direct relationship shows causation. If it is determined that no connection exists between the variables, then the correlation is a coincidence.
Correlation versus Causation
If the dependent variable increases or decreases when the independent variable increases, there is a positive or negative...

Fundamental Attribution Error

13.8K
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...

Higher Mental Functions of Brain: Learning and Memory

2.1K
Memory is one of the most vital higher mental functions of the brain. Memory is closely related to learning because it enables us to retain information and experiences from our past to use them in our present life. It also helps us to remember facts, events, and skills, such as riding a bike or swimming. There are two types of memory — declarative memory, which involves memorizing facts or events, and procedural memory, which enables us to remember how to do something like writing or...

Systematic Error: Methodological and Sampling Errors

11.0K
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...

Correlation

15.2K
In statistics, two variables are said to be correlated if the values of one variable are associated with the other variable. Depending on the relationship between two variables, correlation can be of three types– positive correlation, negative correlation, and zero correlation.
Two variables, for example, a and b, are said to be positively correlated if both variables move in the same direction. In other words, a positive correlation exists between two variables, a and b, if:

Summary
This summary is machine-generated.

Emotional arousal from negative and positive words enhances brain activity related to error monitoring and improves memory recall. This effect is driven by arousal, not just valence, particularly for negative words.

Area of Science:

  • Neuroscience
  • Cognitive Psychology
  • Affective Science

Background:

  • Error monitoring is crucial for cognitive control.
  • Affective states can influence cognitive processes, but their impact on error monitoring and memory is not fully understood.

Purpose of the Study:

  • To investigate if negative and positive words enhance error-monitoring activity.
  • To determine if this enhancement is valence-specific or arousal-driven.
  • To assess the relationship between post-error brain activity and incidental memory for emotional words.

Main Methods:

  • Participants completed an emotional stop-signal task with negative, positive, and neutral words while EEG was recorded.
  • An unexpected free recall test assessed incidental memory.
  • Source localization analyzed brain activity patterns.

Main Results:

  • Significantly greater error-positivity (Pe) brain activity observed for both negative and positive words.
  • Error-related negativity amplitudes were similar across conditions.
  • Better incidental recall for emotional words, with negative word recall correlating with Pe amplitude.

Conclusions:

  • Emotional arousal, particularly from negative stimuli, enhances error monitoring (Pe amplitude).
  • The arousal content, not just valence, drives the emotion-related enhancement of Pe.
  • Enhanced error monitoring and memory recall for negative words may reflect heightened responsivity to negative events.
