Professor Thomas V. Papathomas has been approved to support 2 rising BME sophomore undergrads Mr. Jay Ravaliya and Mr. Harpinder Singh for the Byrne Seminar Summer Research. The funds for this summer research project were provided by V.P. Mike Pazzani to proposals submitted on behalf of students in the Byrne first-year seminars. The purpose of this project is to study the role of certain visual attributes, such as contrast and color, in motion perception. The students will use PsychToolBox, a MatLab-based software package to produce animation sequences that use combinations of visual attributes to elicit visual motion. The practical side of the project is that we can produce interesting demonstrations for the Internet, both for future classes and for a web site. We plan to produce interactive demonstrations were the viewer can use "sliders" to adjust stimulus parameters (spatial and temporal frequency, contrast and eccentricity).
