Catherine Craver Lemley, Ph.D.
Professor of Psychology | 717-361-1330 | 260D Esbenshade

B.S., Columbus State University, 1983 Summa Cum Laude
M.A., Northeastern University, 1985dr catherine lemley in front of floral painting
Ph.D., Northeastern University, 1988

Dr. Lemley’s area of expertise is in visual perception. Her research focuses on the relation between visual mental imagery and visual perception with an emphasis on how what you imagine can interfere with what you actually perceive. Dr. Lemley has also been investigating the way in which cognitive processes, namely mental imagery, can moderate the mere exposure effect, which occurs when very brief exposures to stimuli increase the degree to which a person likes such stimuli. Most recently Dr. Lemley has examined the roles of attention and learning in synesthesia. Synesthesia occurs when the stimulation of a sensory modality (e.g. vision) consistently elicits an involuntary concurrent perceptual experience within the same or in another modality (e.g. taste).

Dr. Lemley has been awarded funding from the National Sciences Foundation and the Pennsylvania Department of Education for three projects she is conducting with students, most recently for fMRI research in synesthesia.

Dr. Lemley involves students in each of her lines of research and has mentored a number of students who have won regional and national awards for their research.

B.A., Bates College, 1991

M.A., University of California, San Diego, 1999
Ph.D., University of California, San Diego, 2003

The main focus of Dr. Roy’s research is on how people's perception of environmental statistics influence their judgments and decisions. His research has examined bias in memory for how long tasks have taken in the past and in prediction for how long they will take in the future. He also examined how people rate their own abilities on various tasks and how characteristics of those tasks influence their self-assessments.

Dr. Roy was part of an Elizabethtown College group that established instrumental music programs at two schools in Pietermaritzburg, South Africa. These visits led to a new line of research in the psychology of music. Specifically, he has been examining how differences in personality predict the role that music plays in people’s lives.
