Marc Wittmann is a research fellow at the Institute for Frontier Areas of Psychology and Mental Health in Freiburg, Germany. He received his doctorate (1997) and habilitation (2007) at the Institute for Medical Psychology of the Medical Faculty of the University of Munich. He is currently working at the Institute for Frontier Areas of Psychology and Mental Health at the University of Freiburg.
His research focuses on time perception as indicator of cognitive functioning and emotion. Time perception ranges from milliseconds to seconds in sensory and sensori-motor processing. It also encompasses decades when memory and the anticipation of life periods are concerned. His studies on different temporal-processing mechanisms employ psychophysical experiments, time perception inventories and functional MRI. In particular, he investigates the effects of different durations, age, psychopharmacological treatment, chronic drug abuse and brain injury on the experience of time.
