Rudolf Groner Explained

Rudolf Groner (born July 26, 1942, Glarus, Switzerland) is a Swiss psychologist, specialized in cognitive psychology and media psychology.[1]

Professional life

Groner received a PhD in psychology at the University of Vienna, Austria, in 1966. From 1968 to 1970 he was postdoctoral fellow at the Center for Advanced Studies in Theoretical Psychology at the University of Alberta, Edmonton, Canada, and member of the Michigan Mathematical Psychology Program in 1969. In 1981 he became Professor of Psychology at the University of Bern.[2] He was invited Visiting Professor at Humboldt University Berlin, at the University of Wollongong, Australia, at Kyoto University and Nagoya University, Japan. From 1998 – 2001 he was appointed Director of the Swiss National Postdoctoral Program "Cognitive Psychology - Basic and Applied Aspects". In 1971 he was the founder of Visllab, the laboratory for the study of cognitive processes and eye movements at the University of Bern.

In 1980, Rudolf Groner initiated an interdisciplinary network called "European Group of Scientists active in Eye Movement Research". This group includes scientists who use eye movement registration as a research tool and develop models based on oculomotor data obtained from a wide spectrum of phenomena, ranging from the neurophysiological to the perceptual and the cognitive level. The group's focus is on the exchange of information on current research, equipment and software. Starting 1981, the group organizes a biennial conference at different locations all over Europe (https://www.eyemovement.org/ecem.html). Over the years, the group published ten edited books. Starting in  2008, Rudolf Groner was founder and chief editor of Journal of Eye Movement Research (JEMR) an interdisciplinary open access journal.

After becoming emeritus at the University of Bern in 2007 Rudolf Groner is now working together with Marina Groner and former collaborators in a spin-off of his former laboratory, scians Ltd. focussing on the transfer of fundamental research to applied settings.[3]

Research

From 1970 to 1990 Rudolf Groner's research interests focused on the mathematical modeling of complex cognitive activities by elementary modules.[4] These modules consist of basic perceptual and attentional processes, and the visual information input is measured by parameters of eye fixations. The underlying processes are assumed as the generating and testing of hypotheses. In cooperation with Marina Groner he developed a hypothetico-deductive theory of cognitive activity based on a set of axioms from which probability distributions of eye movement parameters were derived and compared with empirical data of measured eye fixation distributions.[5] In addition to eye tracking data, the same hypothetico-deductive analysis was applied to other behavioral parameters. The distribution of time spent during problem solving and the probability of erroneous solutions could be predicted by one and the same model that assumes minimal short term memory load which, however, must be compensated by extensive visual scanning of available information from the environment.[6]

Groner, Walder & Groner[7] and Menz & Groner[8] extended Lawrence Stark’s concept of scanpaths to two different classes of scanning processes: local scanpaths which are assumed to operate on the perceptual input bottom-up on a narrow time scale, and global scanpaths driven by cognitive processes top-down and operating on an extended time scale. In a series of experiments they demonstrated the relation of basic visual processes to eye movement control.[9] More recently Groner and his colleagues explored new ways of applying eye tracking to usability research.[10] [11] [12] [13]

In another line of research, Rudolf Groner, Marina Groner and Walter F. Bischof investigated the interdisciplinary aspects and the historical roots of heuristic thinking[14] and applied the distinction between algorithmic versus heuristic approaches as a cognitive style variable assessed and validated by a questionnaire.[15]
