Our lab is housed in the Department of Psychology at the Ohio State University. It occupies 427 square feet in Lazenby Hall (Suite 207). The lab is biosafety approved and fully networked. Currently, four psychophysical data-collection sessions can proceed in parallel in separate rooms. We use  CRTs for calibrated psychophysical displays generated using Psychtoolbox in Matlab. The lab has access to state-of-the-art photometers and other calibration equipment. There is desk space for four researchers, each with a personal Macintosh workstation. We have two laser printers (one of which in color), a color scanner, an overhead projector, a dedicated file server, and a web server. There is also plenty of bookshelf space, file cabinets, a refrigerator, and a microwave oven. Generous software licenses (e.g., Matlab) are provided by the university, and certain specialized software (e.g., EyeLink Data Viewer and Experiment Builder) is purchased with lab funds.

EyeLink 1000 Eyetracker

The lab is equipped with an EyeLink 1000 eyetracker manufactured by SR Research. It consists of desktop optics, host computer, chin rest, various cables, and specialized software. This is a highly capable system with 1000 Hz temporal resolution and 0.15 degrees spatial resolution. It supports gaze-contingent displays in real time. In addition to eye position, it also measures pupil diameter 1000 times each second. All graduate students and some undergraduate students in the lab have access to this expensive equipment. It is used in various projects as detailed on the Research page.

Access to the Ohio Supercomputer Center

Dr. Petrov has an account on the Ohio Supercomputer Center that provides access to several high-performance high-availability Linux clusters for CPU-intensive simulations and analyses. All lab members can access the clusters via sub-accounts of Dr. Petrov’s account. 40,000 CPU-hours on the clusters are currently allocated each year and additional cycles can be obtained at no cost upon request.
