Question

I am writing a paper and for it I am supposed to design my own experiment. I am writing the materials section of my paper and I am stuck. Based on this statement "Based on the previous research that has done on this topic, it can be inferred that extroverts will have higher facial recognition and a high level of activation of their fusiform gyrus when looking at facial stimuli." - what can be used to measure the level of activation the fusiform gyrus when I am having my participants complete a program that was designed for this experiment that will show facial stimuli and non-facial stimuli at random. Would it be a fMRI and if so how will that be pracitcal? or would it be a EEG and if so wouldnt that not measure the precision of the activation to the fusiform gyrus? Also can you help me identify the independent and dependent variable?

thanks!

Explanation / Answer

with fMRI 97% of the visually responsive cells in this region responds selectively to faces. Hence fMRI can be used to measure the level of activation the fusiform gyrus. The statistics is according to a research done on monkeys which is close to the human species.

The dependant variable would be the person which the experiment is conducted on. The independant variable would be the reaction of the subject.
