ABSTRACT:Gestures receive growing attention in the field of Second Language Acquisition but still there is a scarcity of research that looks at them as a part of multimodal communication through the use of interactional approach.The present study aims to explore the interplay of gestures in oral production in German as second language and the lexical access problems. It looks at the principal gesture functions in communication (referential, discursive, interactional, autostimulative) To answer these research questions the speech of 6 Spanish/Catalan (L1) students of German (L2) The results show that the gestures that depict image are scarcely presented and do not participate in word retrieval. The emphatic gestures represent the discursive function in communication.The pointing gestures in the majority of cases are used strategically to prompt reaction from the interviewer, and, thus, play an interactional function, not the referential one. The autostimulative 2 gestures that occur during the lexical access problems may participate in the retrieval but still their role should be investigated more.In our study the higher proficiency is related to the decrease in lexical access problems and the decrease in searches for the abstract words. Its relation to the most frequently presented gestural types is, however, weak. The higher speech rate is related to the decrease in cases with lexical access problems that were produced without gestures, but does not affect gestural types.Frequency of silent pauses is not strongly related neither to the amount of lexical access problems, nor to the type of lexical items, nor to the most frequently presented gestural types.
