¿Sabes si viene un code-switch? Bilinguals can predict upcoming code-switches given enough context

Area of Science:

• Psycholinguistics
• Cognitive Science
• Bilingualism Research

Background:

• Language comprehension relies on predictive processing.
• The extent to which comprehenders predict linguistic elements, including language choice, remains an open question.
• Bilinguals' ability to predict language code-switches is not well understood.

Purpose of the Study:

• To investigate whether Spanish-English bilinguals can consciously predict upcoming code-switches in conversation.
• To determine the role of contextual information in predicting language code-switches.

Main Methods:

• Sentences from spontaneous bilingual conversations were selected, with the final word omitted.
• Spanish-English bilingual participants predicted the language of the omitted word.
• Two experiments were conducted: one with 30 seconds of prior context and one with only the sentence fragment.

Main Results:

• Bilinguals successfully predicted upcoming code-switches when provided with 30 seconds of conversational context.
• Prediction accuracy for code-switches was significantly lower when participants only heard the sentence fragment without extensive context.
• The availability of conversational cues is crucial for predicting language code-switches.

Conclusions:

• Bilinguals possess the capacity for conscious prediction of language code-switches.
• Predicting code-switches is dependent on the amount of available conversational context.
• These findings contribute to our understanding of predictive processing in bilingual language comprehension.
