The AM integrates the mental lexicon with world knowledge, as e.g. acquired via reading books. Following pioneering work by Denhière and Lemaire (2004), here we computed DSMs based on a representative corpus of German children and youth literature (Jacobs et al., 2020) as null models of the AM for readers of different reading ages (grades 1-2, 3-4, and 5-6). After a series of DSM quality tests, we evaluated the performance of these models extensively in various tasks to simulate the different reader-groups’ hypothetical semantic and syntactic skills. In a final study we compared the models’ performance with that of human readers in two rating tasks. Overall the results show that with increasing reading age performance in practically all tasks becomes better. The approach taken in the present studies reveals the limits of DSMs for simulating human AM and their potential for applications in scientific studies of literature, research in education, or developmental science.
