Synchronous brain activity during cooperative exchange depends on gender of partner: A fNIRS‐based hyperscanning study

Abstract

Previous studies have shown that brain activity between partners is synchronized during cooperative exchange. Whether this neural synchronization depends on the gender of partner (i.e., opposite or same to the participant) is open to be explored. In current study, we used functional near‐infrared spectroscopy (fNIRS) based hyperscanning to study cooperation in a two‐person game (female–female, female–male, and male–male) while assaying brain‐to‐brain interactions. Cooperation was greater in male–male pairs than in female–female pairs, with intermediate cooperation levels for female–male pairs. More importantly, in dyads with partners with opposite gender (female–male pairs), we found significant task‐related cross‐brain coherence in frontal regions (i.e., frontopolar cortex, orbitofrontal cortex, and left dorsolateral prefrontal cortex) whereas the cooperation in same gender dyads (female–female pairs and male–male pairs) was not associated with such synchronization. Moreover, the changes of such interbrain coherence across task blocks were significantly correlated with change in degree of cooperation only in mixed‐sex dyads. These findings suggested that different neural processes underlie cooperation between mixed‐sex and same‐sex dyadic interactions. Hum Brain Mapp 36:2039–2048, 2015. © 2015 Wiley Periodicals, Inc.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
