Uso dei segnali discorsivi nell’interazione fra non nativo- non nativo e non-nativo – non nativo in apprendenti ispanofoni di italiano L2

This research explores the role of interactional DM in the dynamics of conversations of Spanish native speakers (with A2 level of proficiency) engaged in two different interaction types: native- non-native (asymmetric) and non-native – non-native (symmetric). Eight learners and two native speakers were involved in two conversational settings: in the first, couples were engaged in an exchanging information type of activity, in the second they had to build a dialogue based on a predefined scenario such as to decide on a gift or to organize a party for a friend. In asymmetrical conversations the dominance of natives in guiding the conversation of non-natives can be shown from the greater number agreement and acknowledgment signals used by the learners. On the other hand, in symmetrical interactions, the variety and the frequency of various DMs used by non-natives, such as turn taking, request for confirmation, displays a higher involvement in the interaction, especially in the role-play situations.
