Scholarly/Research Interests

Professor Vaughan's research interests focus on the selection of motor movements; eye movements and attentional processes; learning; and cognitive neuropsychology. His most current work (with colleagues David Rosenbaum of Pennsylvania State University and Ruud Meulenbroek of the Nijmegen Institute for Cognition and Information) has resulted in computational models that describe performance in tasks such as reaching, grasping, and tapping. With colleague Penny L. Yee, he has also been active in facilitating the use of computer applications in psychological research, his most recent efforts being tutorial materials for the use of the PsyScope program for teaching and research.

Teaching Interests

Professor Vaughan teaches Introductory Psychology, Research Methods in Psychology, and Attention and Performance (an advanced laboratory course in cognitive psychology). He is developing a new sophomore-level course for the spring of 2000, Learning and Cognition, which will integrate laboratory studies of the learning processes with their clinical applications. Like all his departmental colleagues, he encourages student participation in research through summer experiences, independent study, and the Senior Project.
