Word Naming in Bodo–Assamese Bilinguals: The Role of Semantic Context, Cognate Status, Second Language Age of Acquisition and Proficiency

The current study investigated the effects of the semantic context, cognate status of the word and second language age of acquisition and proficiency in two word naming experiments (Experiment 1 and 2). Three groups of Bodo–Assamese bilinguals named cognate and non-cognate words in their first language, Bodo and second language, Assamese, which were presented in categorized and randomized lists. Experiment 1 demonstrated significant category interference for both cognate and non-cognate words; whereas, in Experiment 2, category interference was observed only in case of cognate words, indicating that naming in L2 was more prone to semantic effects. In Experiment 1, the magnitude of the category interference effect was larger for the low proficient bilinguals, but in Experiment 2, only the high proficient bilinguals demonstrated category interference effect. Further, cognate facilitation effect was not observed in both experiments which is in line with the findings of previous studies. The findings are discussed in light of the predictions of the Revised Hierarchical Model.
