Subclaims¶

q3 i? Onset-time of successful positive imitation decreased significantly with repetitions overall and in the late phase, but not in the early phase. → Qi Liu 2025 q3 i? Positive imitation AUC correlated with repetitions primarily during early-phase sessions, not late-phase ones. → Qi Liu 2025 (2)

Evidence¶

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

Repeated measures correlation on onset-time of successful imitation in the same 80-participant FISL course: the article reports "a significant negative correlation between the onset-time of successful imitation of positive emotion and the number of repetitive learning", with no correlations for negative emotions (ps > 0.065).

"a significant negative correlation between the onset-time of successful imitation of positive emotion and the number of repetitive learning during the overall period of FISLs (rrm(879) = -0.105,pFDR = 0.003"

q3 · i? · causal · r1

Repeated measures correlations between positive imitation AUC and repetition number: significant overall and "primarily to the early phase FISLs", non-significant for late-phase sessions, supporting a phase-specific dissociation between performance gains and speed gains.

"due pri- marily to the early phase FISLs ( rrm(399) = 0.170, pFDR = 0.003, 95% CI = [0.073, 0.236]) but not the late phase ones ( rrm(399) = 0.055, p = 0.271, 95% CI = [ −0.043, 0.152])"

Discussion¶

Learner Variables¶

• Processing Speed — outcome: instruction changes it

Related Claims¶

• Imitative learning performance improves across repeated FISL sessions, with a positive-emotion advantage over negative emotions — a broader claim this one bears on
• 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
• Long-term FISL improves fMRI-based classification of emotional faces but not emotional scenes — related
