In this Article, the authors mistakenly used the abbreviation “r” instead of “b” to refer to the beta coefficients resulting from the analysis of the relationship between cooperation behavior and task-related inter-brain coherence. All statistical outcomes and their interpretations remain unaffected and unchanged. As a result,

“This analysis identified a positive relationship between performance and task-related coherence, indicating that greater task performance coincided with greater task-related inter-brain coherence (r = 0.603, p = 0.024) (Fig. 6A). Next, we conducted a series of identical linear regression analyses on each dyad type (male/male, male/female, female/female) individually. These analyses identified significant positive relationships between cooperation performance and task-related coherence across all regions of interest within male/male (r = 0.862, p = 0.035) and female/female dyads (r = 1.195, p = 0.012). This relationship was not significant for male/female dyads (Fig. 6B). When further stratified across the regions of interest, a significant relationship between cooperation task performance and inter-brain coherence was identified within the right temporal region for female/female dyads (r = 0.323, p = 0.028). No other comparisons were significant.”

“(A) Cooperation performance significantly predicts inter-brain coherence (r = 0.603, p = 0.024) across all regions. (B) The relationship between cooperation performance and inter-brain coherence was significant for male/male (r = 0.862, p = 0.035) and female/female (r = 1.195, p = 0.012) groups. This relationship was positive within these groups, indicating that greater behavioral performance coincided with enhanced inter-brain coherence. Conversely, this relationship within male/female pairs was non-significant (p = 0.537, r = −0.147).”
