This research presents the comparison of the frequency of occurrence of different repair categories in the first (L1) and the foreign language (L2), in order to achieve a better understanding of certain aspects of speech production, that is, to find out certain similarities and differences between L1 and L2 processing. The comparison of the repair categories between the first and the foreign language was conducted using the nonparametric Wilcoxon signed-rank test. Significant differences have been observed in the frequency of occurence of the appropriate information repair and the different information repair, respectively. The appropriate information repair can be related to the language proficiency level. In other words, L1 speakers have more available time for monitoring on the level of discourse and propositional content, compared to L2 speakers, whose attentional resources are oriented towards linguistic errors arising at lower levels of processing. Moreover, in L1 the speakers abandon the planned utterance because a different information seems more appropriate, and not because they are not able to finish it. On the other hand, different information repair is one of the communication strategies employed by L2 learners due to insufficient knowledge of linguistic rules and lexical units. However, L2 learners in this research frequently use grammatical reduction as a communication strategy, that is, simplified grammar and shorter utterances, believing that the interlocutor will reconstruct the meaning from the context. The grammatical information is stored in the lemmas, and one of the ways of avoiding grammatical difficulties is to avoid the activation of problematic lemmas.
