James L. Ferguson Professor of Psychology and Neurosecience.
An experimental psychologist, Vaughan's research interests focus on the selection of motor movements; eye movements and attentional processes; learning and cognitive neuropsychology. His recent work has resulted in computational models that describe performance in tasks such as reaching, grasping, and tapping. Vaughan has collaborated with Penny L. Yee in facilitating the use of computer applications in psychological research, their most recent efforts being tutorial materials for using the PsyScope program for teaching and research in Cognitive Psychology. Vaughan has also been editor of the international quarterly, Behavior Research Methods, Instruments, and Computers, published by the Psychonomic Society. He is a Fellow of the American Psychological Association (Divisions 2 and 6), and of the Association for Psychological Science.
Empirical projects with Vaughan will devote the fall semester to the integration of the existing literature in a particular area, the isolation of an appropriate question for further research, and the design and piloting of an experiment. The spring semester will be devoted to acquiring, analyzing and interpreting the data from the actual experiment.
Empirical topics may be selected from areas related to the cognitive psychology and neuropsychology, broadly defined. Previous student projects have been directed at the planning of actions, including movements of the eyes and of the body; memory; attentional processes; and the embodiment of actions.
Projects related to developmental disorders such as autism entail devoting the first semester to a literature review to develop a theoretical understanding of autism, its etiology, underlying physiology, and treatment. The literature review is coupled with regular volunteer work at a local agency such as at the Clinton Elementary School or the Promise Program of the Kelberman Center.
Excellent fall-semester projects may be invited to extend an empirical study through the spring semester using the methods of Applied Behavior Analysis, Social Stories, and similar techniques that the agency (CES or Promise Program) is already using for individual cases. Projects in this area are ordinarily open only to students who have had experience working with children with special needs, who have the recommendation of Hamilton faculty as reliable independent students. A flexible academic schedule with free time through the noon hour on at least two class days, and regular transportation between campus and the project site are required. The number of placements in the local agencies is limited.
