Dr. Bricker wants to find out which part of her volunteers' brains react to seeing unusual information by measuring relative amounts of blood flow to various brain regions. She will most likely collect her data by using __________.

A) archival data
B) a clinical interview
C) fMRI
D) projective tests

fMRI is a brain imaging technique that can measure blood flow changes in response to various stimuli, including unusual information. Therefore, using fMRI would likely be the best way for Dr. Bricker to collect data on which part of her volunteers' brains react to seeing unusual information. The other options (archival data, clinical interview, and projective tests) are not appropriate for this type of research question.
