The cooperation between principled linguistic descriptive models, conceptually refined techniques of arratological text analysis, cognitive psychological paradigms and neuroscientific methods with the goal of clarifying the nexus between text structure, text comprehension and text comprehensibility, is the objective of the CRC “Text Structures”. We examine microstructures including non-canonical sentence constructions, anaphorical relations, tense, aspect, and information-structural parameters as well as macrostructures including narrative perspective, thematic structure, narrative styles, and genre-specific patterns. In a collaborative interdisciplinary effort the CRC’s three junior research groups “Theoretical Linguistics”, “Analytic Literary Theory”, and “Experimental Psycholinguistics” work on a theoretically and empirically sound platform for the description of different text structural levels and their mutual interpretative effects.
