• What is a weakness of Raine et al.'s research?

  It was a quasi-experiment in a controlled environment
• Why is a quasi-experiment not considered a true experiment?

  It lacks manipulation of the independent variable
• How does the lack of control over the independent variable affect the study?

  It complicates establishing cause and effect relationships
• What does the lack of control over the independent variable imply about the results?

  Results may be influenced by extraneous variables
• What is mentioned about the existing participant variable?

  It was not manipulated by Raine
• What does the study suggest about the relationship between variables?

  There may be several extraneous variables affecting results
• What could the lack of control lead to in terms of brain activity results?

  It makes it harder to establish clear relationships
• What does the study imply about the differences in brain activity?

  They could be due to other factors, not just murder
• What is stated about Raine's study's internal validity?

  It is low in internal validity
• What is the counterargument regarding Raine's research method?

  • It was the only ethical way to research brain function
  • It focused on differences between murderers and non-murderers
• What is the main focus of Raine's study?

  Brain function differences between murderers
• What does the study suggest about the ethical implications of the research method?

  It was the only ethical way to conduct research
• How does the quasi-experimental design impact the conclusions drawn from the study?

  It limits the ability to draw definitive conclusions
