Cognate facilitation effect on verb-based semantic prediction in L2 is modulated by L2 proficiency

Abstract

We tested whether verb-based prediction in late bilinguals is facilitated when the verb is a cognate versus non-cognate. Spanish–English bilinguals and Chinese–English bilinguals (control) listened to English sentences such as “The girl will adopt the dog” while viewing a scene containing either a dog and unadoptable objects (predictable condition) or a dog and other adoptable animals (unpredictable condition). The verb was either a cognate or non-cognate between Spanish and English and never a cognate between Chinese and English. Both groups of bilinguals were more likely to look at the target (the dog) in the predictable versus unpredictable condition. However, only low-proficient L1 Spanish bilinguals showed greater and earlier prediction when the verb was cognate than when it was non-cognate, suggesting that cognate facilitation effect occurs not only on the cognate word itself but also on prediction based on this cognate word, and that this effect is modulated by L2 proficiency.
