1.1.4 Raine Evaluation Flashcards
(15 cards)
what type of experiment was used in the study
Quasi- experiment
What does it mean that the study used a quasi-experiment?
The IV and DV were active, but the IV wasn’t truly manipulated—so no causal conclusions can be drawn
Why can’t causal relationships be justified in a quasi-experiment?
Because there is no true manipulation of the IV.
What do the findings suggest about the causes of violent behavior?
Behaviour is not determined by biology alone; psychological, cultural, and situational factors also play a role.
What’s a danger of using a quasi-experimental method?
Readers may misinterpret findings and assume criminal behavior is predetermined and inescapable
What sampling method was used in the study?
Opportunity sampling.
What are the pros and cons of opportunity sampling?
Pro: Convenient
Con: Sampling bias.
What brain imaging technique was used?
PET scans
What is an advantage of PET scans?
They allow study of the living brain, not just post-mortem.
what is a disadvantage of PET scans
They involve radioactive injections, which can be dangerous and potentially cause cancer.
Why was the sample unrepresentative?
Participants had mental impairments and are not typical of all violent offenders.
What does the limited sample mean for the study’s conclusions?
Findings only apply to a specific group of violent offenders and lack population validity.
Can the study be replicated? Why or why not?
No, due to the unrepresentative and restricted sample.
