Dr. Mitchell Metzger is a Professor of Psychology at Ashland University, where he
was hired in 2003 and has served as the department chair since 2007. He earned a B.S.
(1992) in Psychology from Bowling Green State University, and an M.A. (1994) and Ph.D.
(1997) in Experimental Psychology from Kent State University. Prior to coming to Ashland
University, Dr. Metzger worked as an Assistant Professor at Penn State, Shenango in
Sharon, Pennsylvania for six years. 

Dr. Metzger’s graduate training was in biopsychology, where he researched animal models
of memory function, specifically investigating processes involved in retrograde amnesia,
the forgetting of stimulus attributes, and thermoregulatory tolerance. He continues to
study memory and forgetting processes, and has recently been interested in the use of
directed forgetting to explore these functions. To date, he has published more than 20
peer-reviewed works in such journals as Psychobiology, Physiology & Behavior, the
Neurobiology of Learning & Memory, the Journal of General Psychology, the Journal of
Undergraduate Neuroscience Education (JUNE), and Perceptual & Motor Skills. As
professional service, he serves as a manuscript reviewer for a number of journals and
textbook publishers. Dr. Metzger teaches a variety of courses including General
Psychology I and II, Introductory and Advanced Research Methods, Cognitive Psychology,
Theories and Principles of Learning, Physiological Psychology, and Neuropsychology. Dr.
Metzger served as the 'AU in Germany' program director from 2009-2012.
