Abstract
In this study, we experimentally manipulated the phonology of the cross‑script prime‑target dyads in an ERP‑coupled masked priming paradigm to explore the role phonology plays in visual word processing. The written characters of certain bilingual dyads seldom show any visual/orthographic similarity, yet have the same phonological representation. While the Bilingual Interactive Activation (BIA) model relies on the orthographic similarity between the languages in a bilingual dyad, its revised version (BIA + model) additionally banks on the phonological (and semantic) similarity between the words in such dyads. Thus, there exists the need to investigate the role of phonological (and semantic) similarity between the words of a bilingual dyad, especially in the absence of orthographic similarity. Borrowed words from one language to another provide a suitable avenue to explore this question. Cross‑orthographic (or cross‑script) bilingual participants of this study performed the semantic judgment of visually presented words in a masked priming paradigm in each of their languages while we simultaneously collected the event‑related potentials (ERPs). The primes were either translations (different phonology & orthography: P–O–; phonologically incongruent) or transliterations (same phonology & different orthography: P + O–; phonologically congruent) of the target. Overall, the results showed no difference between the two prime conditions. We discuss our findings in light of the BIA and BIA + models of bilingual visual word processing and discuss the relevance of the former model in orthographically distinct bilingual language dyads. A strong body of research proposes that bilinguals activate their non-target language while processing the target language 1–5. Several studies emphasize the role of phonology in bilingual word processing 1. However, some highlight the importance of the script in bilingual visual word processing, especially in orthographically distinct bilingual dyads 6,7. In the current study, we experimentally manipulated the phonology of the prime-target dyads in a bilingual masked priming paradigm (clubbed with event-related potentials) where the two languages do not share any visual or orthographic similarity. We discuss our findings in light of the Bilingual Interactive Activation (BIA 8,9 & BIA + 10) models (see below) that propose the commencement of visual word processing from the letter features. The Bilingual Interactive Activation (BIA) model 8,9 , and its revised version (BIA +) 10 are two influential models that explain the visual word processing in bilinguals. These models propose an integrated bilingual lexicon in which words in a language are processed in a non-selective manner 10. The BIA models follow a bottom-up processing pattern commencing from the letter features to letters with their unique positions within the words and thus to the specific words. The activated words at the word level feed-forward activations to the language nodes, which in turn, would serve as language tags, and these tags inhibit the activated words in the non-target language in the previous (word) level through inhibitory connections. The language nodes, however, do not have any mechanism to facilitate language-specific lexical access at the early stages of visual word processing 11 .
