Modeling others' behaviors has been shown to be significant factors in learning. Research on modeling (and aggression, explicitly) demonstrates that aggression correlates with:

a. violence in the media
b. male testosterone levels
c. social class
d. intelligence and economic status

a. violence in the media

To determine which factors correlate with aggression, you can consult research studies. Here are the steps you can take to find the answer to this question:

1. Identify relevant research studies: Look for scientific articles or research papers that specifically investigate the correlation between aggression and various factors, such as violence in the media, male testosterone levels, social class, intelligence, and economic status.

2. Use academic databases: Access relevant academic databases such as PubMed, Google Scholar, or PsycINFO. You can search using keywords such as "aggression," "modeling," "violence in the media," "testosterone," "social class," "intelligence," and "economic status."

3. Evaluate research studies: Read through the abstracts or summaries of the studies you find. Look for studies that directly examine the correlation between aggression and the factors mentioned.

4. Analyze the findings: Once you have identified relevant studies, carefully evaluate their methodology, sample size, and statistical analyses. Pay attention to the conclusions drawn by the researchers regarding the correlation between aggression and each factor.

Based on the information provided, research on modeling and aggression has shown that the following factors correlate with aggression:

a. Violence in the media: Many studies have explored the link between exposure to violent media (such as television, movies, video games, etc.) and increased aggression.

b. Male testosterone levels: Testosterone, a hormone more prevalent in males, has been studied for its potential influence on aggressive behavior. Research has found correlations between higher testosterone levels and increased aggression.

c. Social class: Some studies suggest that individuals from lower socioeconomic backgrounds may exhibit higher levels of aggression compared to those from higher social classes. However, this relationship is complex and can be influenced by various other factors such as neighborhood conditions, education, and access to resources.

d. Intelligence and economic status: There is mixed evidence about the correlation between aggression and intelligence or economic status. Some studies suggest a negative correlation, meaning that higher intelligence or economic status could be associated with lower levels of aggression. However, this is not universally supported, and there are other factors involved in aggression beyond intelligence and economic status.

To get the most accurate and up-to-date information, it is recommended to review the specific research studies and findings within the field.
