Cross-linguistic semantic preview benefit in Basque-Spanish bilingual readers: Evidence from fixation-related...

Area of Science:

• Cognitive Science
• Psycholinguistics
• Neuroscience

Background:

• Reading involves processing parafoveal information, but semantic extraction from this region is debated.
• Bilingualism introduces cross-linguistic interactions during language processing.

Purpose of the Study:

• To investigate whether semantic information from parafoveal words is processed during reading in bilingual individuals.
• To provide evidence for cross-linguistic semantic effects in reading using electrophysiological measures.

Main Methods:

• Utilized the boundary paradigm with Basque-Spanish bilinguals during a Spanish reading task.
• Recorded Fixation-Related Potentials (ERPs) to analyze brain responses.
• Presented parafoveal previews of Basque non-cognate translations and unrelated Basque words.

Main Results:

• Demonstrated cross-linguistic semantic preview benefit effects in an alphabetic language system for the first time.
• Observed significant modulations in the N400 component, indicating semantic processing.
• Evidence suggests parafoveal word meaning is processed and shared across languages.

Conclusions:

• The meaning of parafoveal words is actively processed and integrated during the reading process.
• Semantic activation occurs across languages in bilingual readers, influencing reading dynamics.
• Findings contribute to understanding the neural basis of reading and cross-linguistic interactions.
