Neural and Behavioral Data on Gesture-Assisted Mandarin Tone Learning

Yezhi Cui's study on figshare, last updated April 22, 2026, investigates the neural mechanisms of Mandarin tone sandhi perception. The dataset includes functional near-infrared spectroscopy (fNIRS) data and behavioral responses from 44 Vietnamese-speaking learners during a tone discrimination task. The data was collected to compare a gesture training group with a no-gesture control group.

Use Cases

• Analyzing the correlation between L-DLPFC activation and behavioral accuracy based on fNIRS and response data.
• Comparing functional connectivity patterns between brain regions based on the described prefrontal cortex interactions.
• Investigating the effect of gesture-augmented instruction on tone sandhi mastery based on the group comparison design.

Strengths

• Includes data from a controlled experiment with 44 participants.
• Combines neural (fNIRS) and behavioral data, enabling multimodal analysis.
• Dataset is openly licensed under CC-BY-4.0.

Limitations

• The dataset is very small at 18.1 KB, indicating limited scope.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
