Title: Challenge and threat meet fMRI: A history

The biopsychosocial model of challenge and threat has its roots in a simple research study published long ago. The identification of patterns of cardiovascular responses marking these motivational states has become more informative as both our understanding of these neurophsyiological processes and assessment technologies have increased in sophistication. The challenge/threat paradigm has been employed by numerous researchers around the world to examine the putative motivational states underlying many social influence processes. Recently, our lab has focused on overcoming the technological hurdles of collecting these sophisticated cardiovascular markers in vivo during functional magnetic resonance imaging research in humans. We can now parse out the effects of motivational states during fMRI studies thereby reducing individual differences in BOLD signal results and also examining the putative CNS mechanisms underlying challenge/threat states.
