Does your regional variety help you acquire an additional language?

Abstract

This study investigates Differential Object Marking (DOM) in Italian speakers from two dialectal areas–North and South Italy–learning Spanish. Southern Italo-Romance varieties exhibit a DOM system through a-marking, like Spanish, whereas the Northern varieties, like Standard Italian, only allow DOM with pronouns. Given the structural differences and similarities among these typologically close languages, we ask whether a stigmatized oral regional variety has the potential to transfer in the acquisition of additional languages. Participants (n = 103) completed an acceptability judgment task (AJT) and an oral production task testing DOM in [±animate, ±definite] DP contexts. The results revealed differences modulated by proficiency in the written AJT that moderately favored the Northern learners and in the oral production task that favored the Southern learners. These findings suggest that low-prestige varieties may not have the full potential to transfer at early stages of acquisition due to their inhibition in formal contexts, but that they can emerge in less formal tasks. We argue that current theoretical models that prioritize linguistic proximity as the primary source of transfer at initial stages of L3 acquisition are unable to capture revealing patterns from understudied sociolinguistic contexts that bring new light to the study of multilingualism.
