Rudolf Groner

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

Professional life

Rudolf Groner received a PhD in Psychology at the University of Vienna, Austria, in 1966. From 1968 – 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 VISLAB, the laboratory for the study of cognitive processes and eye movements at the University of Bern.

In 1980 he founded together with Dieter Heller and Henk Breimer a transdisciplinary network "European Group of Scientists Active in Eye Movement Research" [3] with the purpose of exchanging information about current research, equipment and software, organizing every second year in different European countries an ECEM conference (=European Conference on Eye Movements). Rudolf Groner organized the first ECEM 1981 in Bern, and 2005 the 13th ECEM again in Bern. Over all the years he served as chairperson of the group's scientific committee which consists of the organizers of all previous ECEMs. He was editor of several books based on international conferences and ECEMs, and in 2007 he founded the Journal of Eye Movement Research.

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.[4]

Research

From 1970 to 1990 Rudolf Groner's research interests focused on the mathematical modeling of complex cognitive activities by elementary modules.[5] 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.[6] 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.[7]

Groner, Walder & Groner[8] and Menz & Groner[9] extended Lawrence Stark’s concept of scanpaths to two different classes of sdcanning 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.[10] More recently Groner and his colleagues explored new ways of applying eye tracking to usability research.[11][12][13][14]

In another line of research, Rudolf Groner, Marina Groner and Walter F. Bischof investigated the interdisciplinary aspects and the historical roots of heuristic thinking[15] and applied the distinction between algorithmic versus heuristic approaches as a cognitive style variable assessed and validated by a questionnaire.[16]

gollark: Also, unfortunately the majority of stars in the universe are red dwarves.
gollark: The sun has, what, 99.9% of the solar system's mass?
gollark: That would do NOTHING.
gollark: Only a thousand? REALLY?
gollark: Or destroy it and swap it out for a new one in about 4 billion years.
