Language acquisition in the digital age: L2 English input effects on children’s L1 Icelandic

This article reviews prominent research on non-English-speaking children’s extramural acquisition of English through digital media, and examines the understudied scenario of possible effects of such second language (L2) English input on domestically dominant but globally small first languages (L1s), with Icelandic as the test case. We outline the main results of the children’s part of the Modeling the Linguistic Consequences of Digital Language Contact (MoLiCoDiLaCo) research project, which targeted 724 3–12-year-old Icelandic-speaking children. The focus is on English input and its relationship to the children’s Icelandic/English vocabulary and Icelandic grammar. Although a causal relationship between digital English and reduced/incompletely acquired Icelandic is often assumed in public discourse, our results do not show large-scale effects of L2 digital English on L1 Icelandic. English still seems to be a relatively small part of Icelandic children’s language environment, and although we find some indications of contact induced/reinforced language change, i.e. in the standard use of the subjunctive, as well as reduced MLU/NDW (mean length of utterance/number of different words) in the Icelandic language samples, we do not find pervasive effects of L2 English on L1 Icelandic. On the other hand, the results show contextual L2 learning of English by Icelandic-speaking children through mostly receptive digital input. Thus, the results imply that English digital language input contributes mainly to L2 English skills without adversely affecting L1 Icelandic.
