Scientific Reports 6: Article number: 26492; published online: 08 June 2016; updated: 19 August 2016.

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).”
