Bottom Line: The results revealed that the regular/irregular contrast yields similar patterns in Hungarian, for both nominal and verbal inflection, as in previous studies of non-agglutinative Indo-European languages: the production of irregular inflected forms was both less accurate and slower than of regular forms, both for plural and past-tense inflection.The results replicate and extend previous findings to an agglutinative language with complex morphology.Finally, the study sets the stage for further research examining the neurocognitive substrates of regular and irregular morphology in an agglutinative non-Indo-European language.

ABSTRACT
The contrast between regular and irregular inflectional morphology has been useful in investigating the functional and neural architecture of language. However, most studies have examined the regular/irregular distinction in non-agglutinative Indo-European languages (primarily English) with relatively simple morphology. Additionally, the majority of research has focused on verbal rather than nominal inflectional morphology. The present study attempts to address these gaps by introducing both plural and past tense production tasks in Hungarian, an agglutinative non-Indo-European language with complex morphology. Here we report results on these tasks from healthy Hungarian native-speaking adults, in whom we examine regular and irregular nominal and verbal inflection in a within-subjects design. Regular and irregular nouns and verbs were stem on frequency, word length, and phonological structure, and both accuracy and response times were acquired. The results revealed that the regular/irregular contrast yields similar patterns in Hungarian, for both nominal and verbal inflection, as in previous studies of non-agglutinative Indo-European languages: the production of irregular inflected forms was both less accurate and slower than of regular forms, both for plural and past-tense inflection. The results replicate and extend previous findings to an agglutinative language with complex morphology. Together with previous studies, the evidence suggests that the regular/irregular distinction yields a basic behavioral pattern that holds across language families and linguistic typologies. Finally, the study sets the stage for further research examining the neurocognitive substrates of regular and irregular morphology in an agglutinative non-Indo-European language.

Mean accuracy (a) and mean response times (b) for the regular and irregular inflected forms of the plural and past tense production tasks.In both tasks participants were more accurate and faster at producing regular than irregular inflected forms. Error bars represent Standard Error of the Mean (SEM).

pone.0119003.g001: Mean accuracy (a) and mean response times (b) for the regular and irregular inflected forms of the plural and past tense production tasks.In both tasks participants were more accurate and faster at producing regular than irregular inflected forms. Error bars represent Standard Error of the Mean (SEM).

Mentions: In the mixed effects regression model for accuracy, the maximal random effects structure justified by the data included random intercepts for Items, and by-participant random slopes for Regularity. Regularity (regular vs. irregular) significantly predicted accuracy (F (1, 84.99) = 10.99, p = .001), with participants less accurate at producing irregular than regular inflected forms (Fig. 1A). There was no difference between plural and past tense production (fixed effect of Word Class: F (1, 77.03) = 0.19, p = .66). Follow-up analyses confirmed that the regular advantage held for both plural and past tense production (ps < .02). The Word Class by Regularity interaction was not significant (F (1, 77.03) = 0.15, p = .70), suggesting that the regular advantage was to a similar extent in plural and past tense production.
