Özet:

The research carried out in the recent years indicates that the structures at the syntax-discourse interface fall in a vulnerable domain for bilinguals (Sorace, 2011 for review). Interface Hypothesis (IH) (Sorace, 2006; Sorace & Serratrice, 2009; Sorace, 2011) proposes that cross-linguistic interference occurs when syntax encounter other external cognitive systems like in the case of syntax-discourse interface so that it becomes the locus of difficulties for L2 learners Initially, it was proposed that cross-linguistic interference occurs when syntactic features of the two languages partially overlap (due to the rise of optionality. However, the later studies ((Bini, 1993; Margaza e Bel 2006).) found cross-linguistic interference to occur in bilinguals speaking two typologically similar languages. This study tests the HI with intermediate and advanced Turkish students learning Italian as an L2 on the distribution of overt and null pronoun.
