Generally speaking, I apply Information Theory to reseach on human consciousness: 'How much information (measured in bit) is consciously processed?'

Several influential papers claim that unconscious processes convey more information than conscious processes. According to our re-analyses this claim is based on a methodological pitfall. When compared properly, both processes often convey the same amount of information. Clarifying the empirical evidence in this setting is my first topic.

My second topic arises from a particular methodological issue. When participants are forced to binary decision, they can not convey all the information they have. If you ask 'will it rain tomorrow?' and you only want to hear yes or no, then you miss out on information about how certain this prediction is. Sometimes I am certain it is not raining but sometimes I am not so certain and then you better take an umbrella just in case. This affects the combination of multiple predictions. Think of group discussions in which there is only a majority vote on yes/no answers and compare this to a discussion in which everyone weights their answer according to how certain they are. The latter is better! I investigate this 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.
