Introductory Psychology CLEP Prep Practice Exam

What is the main role of neuroimaging in psychology?

1. To measure the effects of chemicals on brain interactions

2. To study the way in which emotions affect behavior

3. To look at the structure and functioning of the brain

4. To observe changes in behavior over time

The correct answer is: To look at the structure and functioning of the brain

Neuroimaging techniques, such as fMRI, PET, and EEG, are primarily used to study the structure and functioning of the brain in order to understand the neural mechanisms underlying behavior and cognition. Option A, measuring the effects of chemicals on brain interactions, is a valid use of neuroimaging but is not its main purpose. 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
