Abstract
Bilinguals show a large gap in their expressive-receptive abilities, in both languages. To date, most
studies have examined lexical processing. The current study aimed to assess comprehension and production of verb agreement,
i.e., grammatical processing, in bilinguals, and to examine the factors that might modulate them: exposure, age and
language-specific morphological complexity. Twenty balanced Basque-Spanish bilinguals (10 adults and 10 children) were
assessed on comprehension and production of subject-verb agreement in both languages and object-verb agreement in Basque.
Twenty age-matched Spanish-dominant Basque-Spanish bilinguals were assessed in Spanish only. The results revealed a consistent
gap in Basque in both children and adults, with an advantage for comprehension. In Spanish, a gap appeared in children only,
with an advantage for production. The gap size did not vary with the amount of language exposure but with age and
morphological complexity, suggesting that these factors modulate bilinguals’ grammatical processing.
