title: Time course of inhibitory processes in bilingual language processing.
abstract: This study examines the time course of inhibitory processes in Spanish-English bilinguals, using the procedure described in Macizo, Bajo, and Martín. Bilingual participants were required to decide whether pairs of English words were related. Critical word pairs contained a word that shared the same orthography across languages but differed in meaning (interlingual homographs such as pie, meaning foot in Spanish). In Expts 1 and 2, participants were slower to respond to homographs presented along with words related to the Spanish meaning of the homograph as compared to control words. This result agrees with the view that bilinguals non-selectively activate their two languages irrespective of the language they are using. In addition, bilinguals also slowed their responses when the English translation of the Spanish homograph meaning was presented 500 ms after responding to homographs (Expt 1). This result suggests that bilinguals inhibited the irrelevant homograph meaning. However, the inhibitory effect was not observed in Expt 2 when the between-trial interval was fixed to 750 ms which suggests that inhibition decayed over time.
