Subclaims¶

q3 i3 Significant positive Pearson correlations between friend dyad HICT scores and IBS were found in BA9 (DLPFC.R) (r = 0.500) and BA45 (PTR.R) (r = 0.510). → Zijun Yin 2025

q3 · i3 · causal · r1

Pearson correlation analysis across 21 channels relating key-pressing scores to IBS. For friend dyads in HICT, correlations were "(r = 0.500, p = 0.041)" in DLPFC.R and "(r = 0.510, p = 0.036)" in PTR.R; the authors suggest MNS-facilitated coordination benefits friend dyads' performance.

"a significant positive correlation were found in the HICT between friend dyad’key-pressing score and IBS in BA9 (CH07: DLPFC.R) (r = 0.500, p = 0.041), and in the HICT between friend dyad’key-pressing score and IBS in BA45 (CH12: Right Pars Triangularis, PTR.R) (r = 0.510, p = 0.036)."

Discussion¶

Related Claims¶

• Task and interpersonal interdependence interact on intra-brain FC in DLPFC.R and SMG.R: strangers show higher FC under HICT, friends show higher FC under LICT — related
• Task and interpersonal interdependence interact on inter-brain synchrony in the right supramarginal gyrus — related
• High interdependent cooperation tasks yield higher key-pressing scores than low interdependent tasks for both friend and stranger dyads — related
