Surprise! Gestures in Italian and Italian Sign Language (LIS) expressing surprise and surprise-disapproval

In this work I argue in favor of an integrated model of syntax, prosody and gesture in Italian Sign Language (LIS) for two kinds of special questions: counter expectational and surprise disapproval questions. I capitalize on work by Giorgi & Dal Farra (2018; 2019) on oral languages and consider the interaction of these three components in LIS, a language realizing prosody by means of a different modality (non-manual components), paying attention also to the presence of gestures accompanying signs. Furthermore, in order to investigate the cross-linguistic and cross-cultural nature of the gestural component, I conducted a pilot study on the realization of the same sentences in non-western languages: Vietnamese, Korean, Japanese.
