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.

Biographical Information about Author(s)

Inga Majewska, Lynda Arredondo, and McKayla Deleon are students of Valparaiso University studying psychology and/or biology. While having differing interests, ranging from neuroscience to clinical psychology, they all have an interest in brain functioning. They sought the opportunity to work with Dr. Andrew Butler, who recently helped acquire brand new electroencephalography and stimulation tracking equipment. Dr. Butler has been mentoring these students in setting up and maintaining the equipment while running pilot studies and explaining how the equipment functions in studying event-related potentials. The students and their mentor are looking forward to using the equipment to further develop the extent of future research studies on campus.
