Lexical access for bilinguals is hypothesized to be either language selective or non‑selective. The selective account maintains that bilinguals can selectively activate one of their languages while keeping the other deactivated, whereas the non‑selective access hypothesis purports that both languages are automatically activated. These two major hypotheses are often tested experimentally with visual word recognition tasks. While many word recognition studies support the non‑selectivity account (de Groot, Delmaar, Lupker 2000; Dijkstra, Hilberink‑Schulpen, Van Heuven 2010), there is limited research on cross‑language lexical access of different orthographies (see Moon & Jiang 2012). The current study aims to explore the two main hypotheses and investigate whether Korean‑English bilinguals activate Korean while performing a masked priming lexical decision task (LDT) entirely in English. Results tentatively suggest that Korean‑English bilinguals are facilitated by their L1, which endorses the non‑selectivity hypothesis and reveals possible dual activation of both L1 and L2 in a single language task.
