Dr. Slifkin is an Associate Professor in the Department of Psychology. His main area of research interest is human motor control. In particular, he has studied upper-extremity control of movement and force production, and how such control is regulated by visuomotor feedback processes. Much of that research has used healthy younger adult participants, but other research has been based on rodent subjects, healthy older adults, and individuals with Parkinson’s disease. Additional research interests include motor imagery, embodied cognition, the control of interval timing, and the use of time-series analysis techniques (e.g., spectral analysis) to characterize motor-output variability. With colleagues in the Washkewicz College of Engineering, Dr. Slifkin has been involved in research on the use of robotics to help those with spinal cord injuries feed themselves.
