Geoffrey Bingham

Professor Geoffrey P. Bingham, PhD. (Psychology Page, Cognitive Science Page, Class Syllabi)

Ph.D., University of Connecticut, 1985.

Human visual and haptic perception, event perception, coordination and control of motor activity, visually guided reaching. I spent my boomer (b.1954) childhood in Northampton, MA, the Pioneer Valley and surrounding Berkshire hills. My college years were at Trinity College in Hartford, CT and Smith College, interrupted by a year working at the Nantucket Cottage Hospital. After two years working as a computer programmer, I entered grad school studying perception with MT Turvey and RE Shaw at UConn. I did my dissertation on a Fulbright with G Johansson in Uppsala, Sweden, then a fellowship with MA Arbib at UMass, followed by a postdoc studying action with JAS Kelso at Haskins Laboratories in New Haven, CT. In 1989, I joined the faculty in Psychological and Brain Sciences and Cognitive Science at Indiana University.

My current work focuses on 1) using haptic guidance as intervention for children with Developmental Coordination Disorder (DCD), and 2) the learning of novel patterns of coordianation. Children with DCD have difficulties learning or acquiring new motor skills and are typically described as “clumsy” or “uncoordinated.” We have developed a research program that aims to evaluate children who might have DCD and to train children with DCD to perform more effective manual activities like reaching and handwriting using haptic guidance.

Grad Students

Aaron Fath

MA (Cognitive Science), Rensselaer Polytechnic Institute, USA
BA (Mathematics), Rensselaer Polytechnic Institute, USA

I am a PhD candidate in Cognitive Science and Psychology. My research tackles problems relating to human perception and its consequences on the control of action, especially the role of motion perception in the execution of higher visual and motor functions. There are multiple sources of visual information about motion that allow for coherent, stable, and effective behavior across a variety of conditions. My current work is determining the utility of these forms of motion information in a variety of tasks including locomotion, reaching, manual coordination, perception of the time-to-contact, and shape perception.

Xiaoye "Michael" Wang

BA (Psychology), Denison University, OH, USA

I am a second year PhD student in Psychology and Cognitive Science. My current project is on slant perception with different visual information, namely the monocular structure from motion information, the binocular disparity information, and them combined. I am also interested in whether optical flow information would enable event/scene recognition under low vision conditions. .
