In psychology research, fMRI is used to identify ...

Explanation:
fMRI is a functional imaging method that measures brain activity by detecting changes in blood flow and oxygenation. By capturing these changes as a person performs a cognitive task, it reveals which brain regions become active, showing the neural underpinnings of the task. This is what makes it ideal for identifying brain regions involved in cognitive processes. It isn’t about the brain’s structure alone—that would be structural MRI, which maps anatomy rather than function. It also doesn’t measure activity in the peripheral nervous system, or look for genetic markers of behavior, which require different methods.
