Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q3 i? Main coupling directions (STS→IFG and IPL→IFG for positive; IPL→IFG for negative) emerged only at the 16th FISL session, absent in the 2nd and 9th. → Qi Liu 2025

Qi Liu, Siyu Zhu, Can Liu, Yanmiao Yang, Chunmei Lan, Xinwei Song, Benjamin Becker, Keith M. Kendrick, Xinqi Zhou & Weihua Zhao. (2025). Neural signals gradually shift towards inferior frontal gyrus and long-term effects following facial imitation-based social learning. npj Science of Learning. https://doi.org/10.1038/s41539-025-00372-9
q3 · i? · causal · r1
Directed phase transfer entropy (dPTE) analysis of NPS time series among IFG, STS and IPL in the three fNIRS sessions: no main coupling direction at the 2nd and 9th sessions (ps > 0.05), but at the 16th session the article reports the flow "progressively moves towards the IFG".
"These results revealed that as the number of repetitive FISLs increases, theflow of information progressively moves towards the IFG, suggesting a shift in the synergy function within MNS towards the IFG taking a dominant role."
Discussion¶
Related Claims¶
- Long-term FISL increases informational connectivity between the MNS/IFG and social-cognition and reward regions during positive face perception — related
- Imitative learning performance improves across repeated FISL sessions, with a positive-emotion advantage over negative emotions — related
- Long-term FISL improves fMRI-based classification of emotional faces but not emotional scenes — related
- Neural pattern similarity within the MNS increases across FISL sessions, more for positive emotions, and tracks behavioral improvement — related
- Improved positive imitation performance after FISL is mediated by increased MNS neural pattern similarity and MNS–OFC informational connectivity — related
