TY - THES A1 - Marusch, Tina T1 - Language production of inflectional verb morphology in healthy and impaired adult speakers of German and English. N2 - This thesis investigates the processing and representation of (ir-)regularity in inflectional verb morphology in German and English. The focus lies on the predictions from models of morphological processing about the production of subtypes of irregular verbs which are usually subsumed under the category `irregular verbs'. Thus, this dissertation presents three journal articles investigating the language production of healthy speakers and speakers with agrammatic aphasia in order to fill a gap both for the availability of language production data and systematically tested patterns of irregularity. The second Chapter set out to investigate whether regularity of a verb or its phonological complexity (measured in number of phonemes) better predict the production accuracies of German speakers with agrammatic aphasia. While regular verbs were significantly more often correct than mixed and irregular verbs, production accuracies of irregular and mixed verbs for impaired participants did not differ. Thus, no influence of phonological complexity was observed. Chapter 3 aimed at teasing apart the influence of stem changes and affix type on the production accuracies of English speaking individuals with agrammatic aphasia. The analyses revealed that the presence of stem changes but not the type of affix had a significant effect on the production accuracies. Moreover, as four different verb types were tested, results showed that production accuracies did not conform to a regular-irregular distinction but that accuracies differed by the degree of regularity. In Chapter 4, long-lag primed picture naming design was used to study if the differences found in the production accuracies of Chapter 3 were also associated with differences in production latencies of non-brain damaged speakers. A morphological priming effect was found, however, in neither experiment the effect differed of the three verb types tested. In addition to standard frequentist analysis, Bayesian analysis were performed. In this way the absence of a difference of the morphological priming effect between verb types was interpreted as actual evidence for the lack of such a difference. Hence, this thesis presents diverging results on the production of subtypes of irregular verbs in healthy and impaired adult speakers. However, at the same time these results provided evidence that the conventional regular-irregular distinction is not adequate for testing models of morphological processing.

The first study employed the masked priming technique to investigate -ed forms with a group of advanced Arabic-speaking learners of English. The results replicate previously found L1/L2 differences in morphological priming, even though in the present experiment an extra temporal delay was offered after the presentation of the prime words. The second study examined the timing of constraints against inflected forms inside derived words in English using the eye-movement monitoring technique and an additional acceptability judgment task with highly advanced Dutch L2 learners of English in comparison to adult L1 English controls. Whilst offline the L2 learners performed native-like, the eye-movement data showed that their online processing was not affected by the morphological constraint against regular plurals inside derived words in the same way as in native speakers. Taken together, these findings indicate that L2 learners are not just slower than native speakers in processing morphologically complex words, but that the L2 comprehension system employs real-time grammatical analysis (in this case, morphological information) less than the L1 system.
