On the production of interlingual homophones: Delayed naming and increased N400

ABSTRACT: Bilinguals take longer to identify interlingual homophones than control words. For example, Dutch–English bilinguals take longer to identify an English word like “leaf” ([li:f]), a homophone of the Dutch word “lief” ([lif]; meaning “sweet”), than to identify a control word like “branch”. This homophone-delay effect, observed with both visual and auditory presentation, has been interpreted as evidence in favour of language non-selective lexical access. The present article examines whether a homophone effect is also present in word production. Theoretically, homophone production may profit from feedback from a phonemic level back to a lexical level, but may suffer from a semantic conflict during a process of output monitoring. In line with the latter view, the results show (a) a delay in the production of homophones in the second language, (b) an increased error percentage in the production of homophones in both the first and second language, (c) a reduction in P200 amplitude in the production of homophones in the second language and (d) an increase in the N400 in the production of homophones in both languages of the bilingual.
