Introduction:
A longstanding debate in bilingualism centers on whether foreign language (FL) learners attain proficient FL reading primarily through developing native-like mechanisms (accommodation) or leveraging their first language (assimilation). Predominantly shaped by word recognition studies, this debate lacks evidence from natural reading, which integrates grammar and context to provide insights into real-life reading and may hold the key to its resolution.
Methods:
This study addresses this gap by examining natural reading in English among native speakers and Chinese-speaking English learners, using integrated eye-tracking and functional magnetic resonance imaging (fMRI) datasets.
Results:
Using fixation-related brain activation analysis, we replicated the typical reading brain networks and identified both shared and distinct brain regions between the two groups. Exemplar-based pattern similarity analysis revealed that FL learners whose brain activation patterns were more similar to those of native readers or high-proficiency FL learners displayed superior eye movement performance, such as shorter total reading times and regression path durations. However, the similarity to high-proficiency FL learners did not significantly correlate with eye movement measures after controlling for the similarity to native readers, suggesting that proficient FL reading primarily resembles the brain activation patterns of native readers. Furthermore, FL learners whose brain activation patterns were more similar to those of low-proficiency FL learners did not display inferior eye movement performance, indicating the absence of common brain patterns among them.

Conclusions:
Collectively, our study supports the accommodation hypothesis over the assimilation hypothesis, demonstrating that high-proficiency FL learners primarily accommodate the brain activity patterns of native readers, while each low-proficiency FL learner struggles in their own distinct way. This study is the first to investigate the neural mechanisms underlying natural reading in FL learners by integrating eye-tracking and fMRI techniques, providing key insights into FL processing and learning with potential implications for research and education.

The Open Science Special Interest Group (OSSIG) is introducing a reproducibility challenge for OHBM 2025. This new initiative aims to enhance the reproducibility of scientific results and foster collaborations between labs. Teams will consist of a “source” party and a “reproducing” party, and will be evaluated on the success of their replication, the openness of the source work, and additional deliverables. Click here for more information.
Propose your OHBM abstract(s) as source work for future OHBM meetings by selecting one of the following options:
I am submitting this abstract as an original work to be reproduced. I am available to be the “source party” in an upcoming team and consent to have this work listed on the OSSIG website. I agree to be contacted by OSSIG regarding the challenge and may share data used in this abstract with another team.
