A majority of the work done in AMPS Lab concerns mental architecture, although some projects examine particular mechanisms or processes (such as visual attention, response selection, or motor control). Our primary interest is in how modules or sub-systems are inter-connected and how information flows through the system. For example: when a person is given two reasons to make a response, are the two reasons processed separately or are they combined in some manner? To do this work, we use a variety of methods and approaches, including traditional measures of response time and accuracy, response force, mathematical modeling and simulation, and psychophysiological measures, including event-related brain potentials.
