Russell Poldrack is a professor of psychology and neurobiology and director of the Imaging Research Center at the University of Texas at Austin. In his research he uses imaging to understand the brain systems that underlie the human ability to learn new skills, make good decisions, and exert self-control. What Poldrack and his colleagues discovered in their investigations provides information useful to journalists as they look for ways to engage the minds of readers, viewers and listeners through digital media. He blogs for The Huffington Post about his research.
