The articles presented in fMRI in Media Psychology Research represent a new approach to the study of media use and effects. This special issue focuses on identifying patterns of brain activations in research participants who have viewed video stimuli or played video games while neuroimaging was assessed. The fi rst article seeks to identify the brain network in adults responsible for comprehending a combination of images in a video montage. The second report studies the effects of viewing video violence on children's brain activations. In the third study, the authors analyze the brain activations of adult male research participants recorded as the participants played video games varying in degree of virtual violence. Such an ability to watch the brain's responses to various media in 'real time' promises the potential to fi nd biological bases for behavioral changes as a result of media exposure-a process that has intrigued researchers for decades.
