Calibrating Electroencephalography and Stimulation Tracking Devices for the Study of Event-Related Potentials

We use information from multiple senses during perception, learning, and memory. Much is unclear about the ways in which multisensory experiences modulate measures of subsequent processing in the brain in conjunction with behavioral measures of memory. The current project uses Electroencephalography (EEG) and behavioral measures to study these phenomenon. EEG is a non-invasive electrophysiological monitoring method used to record electrical brain signals. EEG’s ability to track temporal brain activity with a fine resolution has made it a staple in the field of bio-psych research. Valparaiso University’s Psychology Department recently acquired a new EEG device along with a stimulation tracker to be used for research studies. Crucially, this new technology allows us to study event-related potentials (ERPs). ERPs reflect the brain's response to specific stimuli and tasks. This opens the door for more sophisticated studies and measurements in our lab. Therefore, one purpose of this project was to help calibrate the two devices with one another and conduct pilot studies to use the devices in future research studies. In addition, we aim to provide further insight into how simultaneous auditory and visual information may aid in encoding and recalling visual stimuli.
