Dr. Dalmaijer is a cognitive neuroscientist who revolutionized eye tracking with his PyGaze toolbox. This open source eye tracking software has made eye tracking affordable for nearly any research laboratory. Although Edwin’s software can be used to interface with expensive (>$30k) eye trackers, it also wraps around the APIs of cheap, consumer-grade eye trackers intended for gamers. As Dr. Dalmaijer has shown in his careful testing, these cheap eye trackers are sufficient for many research applications. PyGaze has allowed the PEEP lab to send eye trackers all over the US to collaborating labs and even a psychiatric hospital.
Dr. Dalmaijer designed our gaze-contingent operant conditioning study and recently presented the work at the European Conference on Eye Movements. You can find his invaluable book on programming in Python for psychologists here, which is a must-read for any graduate student or advanced undergraduate in psychology.
University of MississippiDr. Morris conducts transdiagnostic research on stress and pain
disorders, with a focus on racial disparities in mental health. He and
Dr. Armstrong are conducting eye-tracking research on the
nature of racial differences in disgust sensitivity and
contamination-based OCD. They are also conducting research on
attentional biases in PTSD and chronic pain disorders. In 2017, Mira
Engel, a PEEP lab member, spent a summer in Dr. Morris’s lab
conducting research and learning pain assessment methodology. The data is reported in this manuscript.
Thröstur Björgvinsson & Courtney Beard
McLean Hospital / Harvard Medical SchoolDr. Björgvinsson directs the Behavioral Health Partial Hospital Program at McLean Hospital and is a pioneer in the intensive treatment
of OCD. Dr. Beard directs the research program at the partial hospital
and develops novel cognitive interventions for anxiety disorders. In
2017, Dr. Armstrong and three PEEP lab members (Rachel Leiter, Hannah
Bouwman, & Trevor Press) visited McLean to set up an eye-tracking
system. In 2018, Dr. Armstrong and PEEP lab member Sara Federman are
returning to McLean for 9 weeks to complete an eye tracking project on
anhedonia in depression with Drs. Beard and Björgvinsson.
West Virginia UniversityDr. Steinman is a clinical psychologist who studies anxiety-related
disorders and OCD. She and Dr. Armstrong recently finished data collection on a study examining oculomotor avoidance of spiders, which is part of an ongoing eye tracking collaboration.
Dr. Stewart is a clinical psychologist who studies suicide and self-injurious behaviors in youth. He and Dr. Armstrong successfully applied for a small grant from Canada’s Social Science and Humanities Research Council to create an eye tracking station in Dr. Stewart’s lab. PEEP lab member Siri Danielson worked with Dr. Stewart during the summer of 2019 on a project using eye tracking to assess risk factors for suicide. Some of the data are reported in this paper.
Dr. Hsu is Assistant Professor in the Department of Psychiatry at Georgetown University. He studies the role of basic cognitive processes in depression and anxiety, with a focus on measurement. He and Dr. Armstrong recently finished a paper on the measurement of disgust.
Meredith Chviers & Samantha Dawson
Queens University & University of British Columbia
Dr. Chivers is an Associate Professor of Psychology at Queens University, and Dr. Dawson is an Assistant Professor at University of British Columbia. They both study gender and sexuality, and have conducted pioneering work using eye tracking to measure sexual arousal. Dr. Armstrong is assisting them with eye tracking data analysis, and their work will guide Zoe Brown’s thesis project on the role of disgust in sexual dysfunction.
Dr. Armstrong completed his supervision under the excellent mentorship of Dr. Olatunji. He and Dr. Armstrong continue to collaborate and recently conducted a meta-analysis of over 100 studies examining the role of disgust in anxiety-related disorders.
Emory UniversityDr. Treadway is a clinical psychologist and neuroscientist studying
the roles of decision making and dopamine in depression. In 2016, PEEP lab member Anneka Soenstram spent a summer learning neuroimaging methods in Dr. Treadway’s laboratory and then conducted her thesis research in the PEEP lab exploring spontaneous blink rate (measured by an eye tracker) as a proxy for striatal dopamine. PEEP lab members also used Dr. Treadway’s EEfRT task, in conjunction with eye tracking, to parse components of reward processing.
