The effect of L2 German on grammatical gender access in L1 Polish: proficiency matters

Abstract

Abstract Previous research has shown that bilinguals process nouns that have the same grammatical gender in their two languages faster than nouns that differ in gender between L1 and L2. This finding, referred to as the gender congruency effect, has so far only been documented in L2. Hence, the aim of the present study was to examine whether late unbalanced bilinguals would also show gender congruency effects in their L1. To that end, 44 L1 Polish/L2 German bilinguals were tested in a gender decision task in Polish, which included gender-congruent and gender-incongruent nouns. The results revealed a robust gender congruency effect in L1, which was limited to bilinguals with very high L2 proficiency. This indicates that bilinguals activate grammatical gender information in L2 when accessing gender in L1, providing that they are highly proficient in L2. More broadly, the study demonstrates that foreign language knowledge can affect native language performance in exclusively native contexts. Finally, as a first attempt to examine grammatical gender access in Polish, this study shows that feminine gender is accessed faster compared to masculine and neuter, suggesting that the ending -a is the most reliable gender cue in Polish.
