A growing body of work in psycholinguistics suggests that morphological relations between word forms affect the processing of complex words. Previous studies have usually focused on a particular type of paradigmatic relation, for example the relation between paradigm members, or the relation between alternative forms filling a particular paradigm cell. However, potential interactions between different types of paradigmatic relations have remained relatively unexplored. The data in in this data set were used in two corpus studies of variable plurals in Dutch to test hypotheses about potentially interacting paradigmatic effects. The first study (which uses the s_dist data) shows that generalization across noun paradigms predicts the distribution of plural variants, and that this effect is diminished for paradigms in which the plural variants are more likely to have a strong representation in the mental lexicon. The second study (which uses the s_dur data) demonstrates that the pronunciation of a target plural variant is affected by coactivation of the alternative variant, resulting in shorter segmental durations. This effect is dependent on the representational strength of the alternative plural variant. In sum, the distributional and durational measurements in these data provide evidence that storage of morphologically complex words may affect the role of generalization and coactivation during production. A full description of the data gathering process and the analyses is given in the Methodology file. The Readme file describes how the remaining files relate to the research.
