Naturalistic Observations

15.4K
If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...

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?

Fundamental Attribution Error01:14

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 Testing

180
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%...

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?

Social Proof

Social proof is a form of persuasion based on comparison and conformity. People compare their behavior and actions to what others are doing and will change to conform to do what their peers do.

Area of Science:

  • Social Network Analysis
  • Public Health Research
  • Informant Accuracy Studies

Background:

  • Personal network studies rely on respondent (ego) perceptions of their network members (alters).
  • Previous research on informant accuracy in these studies yields inconsistent findings regarding reporting accuracy.
  • Understanding accuracy is crucial for the validity of network data, especially in vulnerable populations.

Purpose of the Study:

  • To evaluate the accuracy of self-reported network data in a study of people living with HIV/AIDS (PLHA) in Uganda.
  • To identify factors associated with accuracy or inaccuracy in ego-alters relationship reporting.
  • To contribute to the literature on informant accuracy within personal network research.

Main Methods:

  • Egos (PLHA) were asked to nominate up to four alters from their network.
  • Alters were interviewed about their relationship with the ego.
  • Gower's general coefficient of similarity was used to measure accuracy by variable and by alter.

Main Results:

  • Analysis by variable generally supported existing informant accuracy research.
  • Analysis by alter provided new insights into individual ego accuracy when describing alters.
  • Identified characteristics associated with varying levels of reporting accuracy.

Conclusions:

  • Informant accuracy in personal network studies is variable and depends on the specific alter being discussed.
  • Further research is needed to explore characteristics influencing ego-alters reporting accuracy.
  • Findings have implications for interpreting network data in HIV/AIDS research and other public health contexts.
