Generally speaking, I apply Information Theory to reseach on human consciousness: 'How much information (measured in bit) is consciously processed?'
More precisely, I review claims that unconscious processes can convey more information than conscious processes. It does not appear such a clear cut. How much information humans consciously process is often underestimated because they are forced to a binary choice. This overlooks information.
For example when one asks: 'Will it rain tomorrow?' If one only wants to hear yes or no, then one discards information about how certain this prediction is (certainly no rain vs. maybe no rain but take an umbrella just in case). This additional information from confidence ratings helps when multiple predictions are combined, which I also investigate under the term theoretical boosting performance.


I studied Human-Computer-Interaction (B.Sc.) and Psychology (B.Sc.) simultaneously and after that Informatics (M.Sc.) at the University of Hamburg. Starting with my master thesis I worked at the Theory of Machine Learning and Experimental Cognitive Science groups in Tübingen. Now I work as a Ph.D. student in a joint project between both groups.
