Mouthing e mouth gesture nella lingua dei segni italiana. Descrizione, consapevolezza e acquisizione di un fenomeno ubiquo, complesso e dibattuto
What and how do signers labialize in the act of signing? Is labialization related to the interface between form and rhythm of the sign? What do signers think about this phenomenon? Are oral components considered in LIS (Italian Sign Language) teaching? These are some of the ques- tions that we posed and attempted to answer. To shed light on such a controversial phenomenon, a questionnaire was designed and disseminated online. It involved over 273 deaf and hearing signers from all over Italy.
