Reanalyzing language expectations: Native language knowledge modulates the sensitivity to intervening cues during...

Area of Science:

• Psycholinguistics
• Neuroscience
• Cognitive Science

Background:

• Native language experience significantly influences cognitive processes, including language comprehension.
• Bilingual language processing involves complex interactions between linguistic systems.
• Anticipatory language processing, or predicting upcoming words, is a key aspect of efficient comprehension.

Purpose of the Study:

• To investigate how native language background affects anticipatory language processing in bilinguals.
• To examine the neural correlates of predicting upcoming nouns based on grammatical gender cues.
• To test the
• retracing hypothesis
• in the context of bilingual language comprehension.

Main Methods:

• Event-related potentials (ERPs) were recorded from Spanish and Basque native bilinguals performing word and picture matching tasks.
• Participants processed Spanish noun phrases where determiners preceded nouns, with noun endings being either gender-diagnostic (transparent) or ambiguous (opaque).
• Analysis focused on brain activity time-locked to determiners, comparing gender-congruent and incongruent conditions to assess prediction and reanalysis.

Main Results:

• Both groups exhibited a late N400 effect in the word matching task.
• Basque natives showed an earlier P200 effect for determiners preceding transparent nouns, suggesting earlier sensitivity to gender cues.
• In the picture matching task, both groups displayed an early P200 effect for determiners preceding opaque nouns, indicating reliance on non-linguistic cues when grammatical information was ambiguous.

Conclusions:

• Native language experience modulates the timing and nature of anticipatory language processing.
• The findings support the
• retracing hypothesis
• , where the brain revisits linguistic representations to update expectations.
• Bilinguals dynamically utilize available linguistic and non-linguistic information to predict upcoming words.
