Behavior-contingent analysis of fixation-related brain potentials: Past findings and new tools for co-registration research
Elizabeth Schotter
Department of Psychology, University of South Florida
Recent years have seen a rise in excitement around co-registration (i.e., synchronized measurement of eye tracking, ET and electroencephalography, EEG), which allows researchers to investigate eye fixation-related brain potentials (FRPs). One major focus of co-registration research has been on the reading process – a naturalistic task that involves the interface of many cognitive, perceptual, and motor systems, allowing it to be a testbed for many questions within cognitive neuroscience. But future progress hinges upon researchers synchronizing not only data streams, but also approaches to analyzing the data in a way that capitalizes on the technique’s strength — the ability to directly link neural processing to eye movement behaviors. To make the most of this technique, we must move away from univariate analysis (i.e., treating ET and EEG data as independent outcomes) and toward approaches that account for the multivariate coupling between neural processing and behavioral actions. As an example, I will summarize a few co-registration studies that use behavior-contingent analysis (BCA) to reveal how language-related brain processes (e.g., N400, LPC) are only observed when the reader exhibits specific behaviors (e.g., skipping, regressions). Furthermore, in order to facilitate adoption of these integrated approaches to co-registration research, I will provide an overview of a MATLAB toolbox my lab has developed (i.e., EyeSort) that will allow co-registration researchers to identify certain eye movement behaviors and mark them in the EEG event structure in a way that is flexible and customizable.

About CRL Talks
We look forward to seeing you at Friday at 11 a.m. in CSB 280 or via Zoom. The Zoom link for each talk will be provided in the CRL Talks announcement email. If you are not subscribed to CRL Talks announcements, just sign up to our new Google Group!.
If you still do not want to subscribe to the CRL Talks mailing list, that's okay. Contact the CRL Talks organizer for the details.
Speakers have given everything from practice talks for conferences, job talks, or degree requirements to any new research they want feedback from the CRL community on! Talks are typically 45 min with ~10 min for questions. We love hearing from new grad students and faculty, but you are always welcome to present again! If you, anyone in your lab, or anyone visiting you is interested please let me know so I can arrange dates with them!
If you have someone you would like to hear from, we always enjoy suggestions of who to invite to speak as well!
We have been hoping to encourage more in-person participation/presentation, but there is a Zoom option available for those unable to join in person!
If you would like to send a message to the CRL community, please email it to crl@ucsd.edu (note all messages need to be approved by one of our managerial staff).
CRL ASL-Interpreter Request Form
Please fill out this form out prior to any talk you would like to attend but require ASL interpreters. We will do our best to provide them! If you are planning on coming to a CRL talk and are able to request interpreters for all those who need it, please let us know as well!
