(2015): Disrupting morphosyntactic and lexical semantic processing has opposite effects on the sample entropy of neural signals. In: BRAIN RESEARCH 1604, S. 1-14
Abstract: Converging evidence in neuroscience suggests that syntax and semantics are dissociable in brain space and time. However, it is possible that partly disjoint cortical networks, operating in successive time frames, still perform similar types of neural computations. To test the alternative hypothesis, we collected EEG data while participants read sentences containing lexical semantic or morphosyntactic anomalies, resulting in N400 and P600 effects, respectively. Next, we reconstructed phase space trajectories from EEG time series, and we measured the complexity of the resulting dynamical orbits using sample entropy an index of the rate at which the system generates or loses information over time. Disrupting morphosyntactic or lexical semantic processing had opposite effects on sample entropy: it increased in the N400 window for semantic anomalies, and it decreased in the P600 window for morphosyntactic anomalies. These findings point to a fundamental divergence in the neural computations supporting meaning and grammar in language. (C) 2015 Elsevier B.V. All rights reserved.

(2008): Frames und sprachliches Wissen. Kognitive Aspekte der semantischen Kompetenz. Dissertation. Berlin: Walter de Gruyter
Abstract: The book is concerned with frame theory, which in recent years has experienced an immense growth in interest, not only in Germanic Linguistics. Frames are knowledge structures in the long-term memory which are of relevance for understanding expressions in language. Thus, for example, the gratuity frame makes knowledge available about eating in a restaurant. Frames can also be deployed as analytical tools. This is demonstrated using the metaphor of "financial investors as locusts" coined by the then-SPD Minister of Labour Franz Müntefering
