Dr. Johnson's research is concerned with using event-related brain potentials (ERPs) to characterize and quantify the nature of the processes and neural systems underlying such cognitive processes as evaluative judgments, executive functions, deception, and long term memory. Current scientific collaborations are aimed at investigating the cognitive and neural basis of changes in memory and executive function with aging.
