IB Psychology: Baumgartner et al. (2008)

Baumgarten carried out a study to investigate the role the hormone oxytocin may play in trust relationships. You can use this study for the following learning objectives:Explain how principles that define the biological level of analysis may be demonstrated in research.Discuss how and why particular research methods are used at the biological level of analysis.Explain functions of two hormones in human behaviour.

Hello John,
I am wondering if the students are required to describe the experiment in detail in the external exam. Do they have to describe the "trust game"

Thank you.

Dear Mohamed - they should be able to demonstrate a general understanding of the procedure. They do not need to describe the trust game.

Hello John, for a potential question 'Explain the role of one hormone in human behaviour making use of one study.' If students use Baumgartner, do they have to explain the role of oxytocin on the amygdala and caudate neucleus? Or can they just explain the role that oxytocin has on participants continuing to invest at similar rates, even if there were breaches of trust. Thank you

If the question is to explain the role of one hormone, I think that the role in decreasing activity in the amygdala is an important understanding for students. Otherwise, it does not answer the "explain" part of the question. Why would oxytocin lead to more trust?

Great, thanks for clarifying John! Your previous comment of students having a general understanding of the procedure made me think twice. Very helpful, thanks again.
