Option B, studying the effects of emotions on behavior, is more commonly done through behavioral studies and self-report measures. Option D, observing changes in behavior over time, can also be accomplished through behavioral studies and longitudinal research without the need for neuroimaging. Therefore, option C is the most accurate and specific answer to the question. Neuroimaging may also play a role in measuring the effects of chemicals (option A) and emotions (option B) on brain functioning, as well as observing changes in behavior over time (option D), but these are not its main
