Subclaims¶

q3 i? Across 12 analyzed FISL sessions, imitative learning performance showed significant main effects of repetition number and emotion valence, with greater AUC for positive than negative emotions. → Qi Liu 2025 q3 i? Emotion valence and repetition number interacted significantly, indicating valence-specific learning trajectories. → Qi Liu 2025 (2)

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

Behavioral analysis of 80 male participants' auto-decoded imitation performance (FaceReader) across 12 analyzed sessions of a 16-session FISL course; a two-way ANOVA found significant main effects of repetition and valence, with the quoted means showing the "greater area under the curve (AUC) for imitative learning performance of positive emotion".

"with greater area under the curve (AUC) for imitative learning perfor- mance of positive emotion (mean ± SD = 2.77 ± 1.25) compared to negative ones (mean ± SD = 0.98 ± 0.37)"

q3 · i? · causal · r1

Same behavioral ANOVA in the Results: the article reports "a significant interaction effect between emotion valence and the number of imitative learning", indicating the learning trajectory differed for positive versus negative expressions. No standardized effect size beyond the printed partial eta-squared is interpreted here.

"a significant interaction effect between emotion valence and the number of imitative learning ( F(11, 869) = 3.963, p < 0.001, ƞ2 p = 0.061) was found"

Discussion¶

Related Claims¶

• Improved positive imitation performance after FISL is mediated by increased MNS neural pattern similarity and MNS–OFC informational connectivity — related
• Early-phase FISL improves whole-process imitation performance while late-phase FISL selectively speeds successful imitation of positive emotions — a narrower finding that bears on this claim
• Neural pattern similarity within the MNS increases across FISL sessions, more for positive emotions, and tracks behavioral improvement — related
• Information flow within the MNS progressively shifts toward IFG dominance over repeated FISL sessions — related
• Long-term FISL improves fMRI-based classification of emotional faces but not emotional scenes — related
