Christopher Pagano will give a talk April 14 as part of the CBS Colloquium Series.

The Department of Psychology and the Cognitive Behavioral Sciences (CBS) Colloquium Series will present a talk titled, “Perceiving Haptic Distance-To-Break in a Simulated Minimally Invasive Surgery Task,” with Christopher Pagano, Ph.D., on Friday, April 14, at 2 p.m. in 48 DeGarmo Hall. Pagano is a professor in the Department of Psychology at Clemson University.


In minimally invasive surgery (MIS), it is critical to accurately interpret haptic information and apply appropriate force magnitudes onto soft tissue in order to minimize tissue trauma. The surgeon’s administration of force onto tissue reveals useful perceptual information which guides further haptic interaction making the force perception in MIS a dynamic process. We hypothesized that the compliant nature of soft tissue during force application provides biomechanical information indicating imminent tissue failure.

Specifically, the relationship between applied force and material deformation rate specifies the distance remaining until the tissue will fail, which we termed distance-to-break (DTB). Attunement and calibration training was employed to investigate whether observers are able to identify material break points in simulated compliant materials through haptic force application. Findings underscore the importance of haptic invariants such as DTB and the efficacy of using simulators to train haptic skills.

CBS Colloquium Series

The CBS Colloquium Series brings high caliber researchers to the Illinois State University campus to share their work with the local academic community. Individual faculty members invite speakers to campus based on their interests. The Department of Psychology also invites alumni to speak in the series in an effort to maintain strong connections with former students and provide them with a chance to pass on their knowledge to current students. The series provides both faculty and students with a variety of professional development opportunities and allows students to network with professionals in their field of study.

This speaker series is sponsored by the Department of Psychology, the Harold K. Sage Foundation, and the Illinois State University Foundation. To support the Department of Psychology and help enhance its educational mission with advanced teaching methods, guest speakers, and more opportunities for students to learn through research experiences, please consider making a gift to the department through the Illinois State University Foundation.

If you need a special accommodation to participate in this program, call the Department of Psychology at (309) 439-8651. Please allow sufficient time to arrange the accommodation.
