Abstract: We take the view that commonly used brain imaging techniques add new and informative data to psychological research. As with any new measure, we need to decide how to use it in an appropriate way. How does the measure help answer theoretical questions in ways that existing measures cannot? Is the measure best used as a dependent variable or as a predictor variable? How does it relate to other psychological variables of interest? This new imaging technology provides exciting glimpses into the workings of the brain and its relation to psychology. Researchers need to figure out how the information provided can be used to advance the understanding of psychological phenomena.

Key words: fMRI, statistical modeling, psychological theory
