| Outline of Research at the Start |
Until now, behavioral data on a bilingual advantage in executive function has not yet been clearly supported by neuroimaging. Proven existence could have profound implications for neurodegenerative disease treatment and/or provide justification for reform of second and foreign language education. Differential brain activation (or lack thereof) between subjects of differing English proficiency could help shed light on this contentious subject.

| Outline of Annual Research Achievements |
During fiscal year 2023, to explore the effects of second language (L2) proficiency on frontal brain activity of L1-Japanese-speaking Kyushu University students during a verbal fluency task to determine the existence of a bilingual advantage in executive function, data was collected from an additional 16 subjects (for a total of 20 since the start of the experiment).
Raw data collected included the following: demographic data, handedness data, English vocabulary level as measured by the Pearson Expressive Vocabulary Test, and changes in oxygenated hemoglobin level in pre-frontal brain areas during a "FAS" test as measured by 16-channel functional near-infrared spectroscopy (fNIRS) device.
Raw data is currently being prepared for data analysis to determine if differences in L2 proficiency can be observed in frontal brain regions using neuroimaging.
