CV Kai Hamburger

Assistant Professor of Experimental Psychology and Cognitive Science, Justus Liebig University, Giessen, Germany

PD Dr. Kai Hamburger is Assistant Professor at the Department of Psychology, research group Experimental Psychology and Cognitive Science. There, he is the principal investigator in the field of Spatial Cognition, with strong connections to reasoning and consciousness. Furthermore, he is in charge of supervising the experimental (cognitive) research projects of students and PhD candidates. Furthermore, he is the institutional Erasmus+ coordinator (international student exchange).

Dr. Kai Hamburger is a psychologist by training. He has a strong background in Perceptual Psychology (PhD thesis) and the Cognitive Sciences (Habilitation). His research interests (mainly) cover the following areas:


  • Spatial Cognition (landmark-based wayfinding; multimodal processing; cognitive abilities and inter-individual differences; Neuroscience);
  • Reasoning (formal logic; everyday reasoning; cognitive biases; the influence of emotions on cognitive processes);
  • Consciousness (Philosophical issues on consciousness, such as consciousness as an illusion; experimental methods to investigate consciousness; Neuroscience; AI);
  • Visual illusions (perception; cognitive processes; Neuroscience) Qualifications


  • Diploma (Psychology), Johann Wolfgang Goethe University, Frankfurt, Germany, 2004
  • PhD (dr. rer. nat.), Justus Liebig University, Giessen, Germany, 2007
  • Habilitation (dr. habil. and PD, venia legendi in Psychology), Justus Liebig University, Giessen, Germany, 2015

Kai Hamburger has published over 50 refereed scholarly articles and book chapters. His H-index (a measure of the extent to which his work is cited by other scientists) is 16 (computed by Google Scholar).
