Subclaims¶

q3 i? Under BOTH and ONE, State 1 had significantly higher globE and Cp and significantly lower Lp than States 2 and 3, and showed significantly increased ISFC concentrated in the mirroring and mentalizing systems. → Xinyue Wang 2024 q3 i3 The occurrence rate of State 1 was positively correlated with RPP originality (r = 0.43) and sqrt(IOC) (r = 0.44) under the BOTH condition. → Xinyue Wang 2024 (2)

q3 · i? · causal · r2

Dynamic brain network analysis (sliding windows and k-means clustering of WTC-based ISFC, 27 dyads; Table 1). The article reports that under BOTH and ONE, "State 1 had significantly increased ISFC that concentrated in the mirro ring and mentalizing systems" while States 2 and 3 did not.

"under the ‘BOTH’and ‘ONE’conditions, State 1 had significantly higher globE, Cp and significantly lower Lp than State 2"

q3 · i3 · causal · r2

Correlational analysis linking occurrence rates of dISFC states to behavioural indices after validation analysis in the 27-dyad study. Both printed correlations support that State 1 "might represent an efficient state of information exchange and cognitiv e alignment among communicators".

"the occurrence rate of State 1 was positively correlated with RPP originality and sqrt (IOC) under the ‘BOTH’condition (Originality: r = 0.43, P = 0.041; sqrt [IOC]: r =0 . 4 4 ,P = 0.020;"

Discussion¶

Related Claims¶

• Behaviour locking shows interactive gestures accompany the superior inter-brain state (State 1), while the absence of gestures accompanies the inferior state under ONE — a narrower finding that bears on this claim
• Averaging brain connectivity over the whole task period failed to detect intra-brain differences between gesture conditions, motivating dynamic analysis — related
• Fluid gestures accompany the superior intra-brain state (State 1) of the gesturing participant, whose occurrence rate correlates with fluency — related
• Global efficiency declined across stages where tested while local efficiency differed significantly between stages in each task — related
• Montessori-schooled children show shorter average shortest path length and lower modularity in their semantic networks than traditionally-schooled children — related
