Abstract
Emotional communication is crucial for maintaining the romantic relationships of couples, particularly in situations of failed cooperation. However, little is known about how expressions of happiness and anger affect the subsequent behavioural performance of couples and their neural synchrony mechanisms in the context of cooperative failure. To address this, lover dyads were asked to perform a cooperative task with a high probability of failure while viewing their partner’s happy or angry expressions as feedback. Meanwhile, neural activity was recorded via functional near-infrared spectroscopy. Results showed that happy expressions promote intraindividual emotional experience, emotional similarity, and cooperative performance more than do angry expressions, and such a facilitated effect was associated with higher interpersonal neural synchronization (INS) in the right Middle Frontal Gyrus (MFG) and lower INS at right Superior Frontal Gyrus (SFG). These findings can guide emotional communication strategies for couples in managing failures and promoting positive interactions.
期刊介绍:
Biological Psychology publishes original scientific papers on the biological aspects of psychological states and processes. Biological aspects include electrophysiology and biochemical assessments during psychological experiments as well as biologically induced changes in psychological function. Psychological investigations based on biological theories are also of interest. All aspects of psychological functioning, including psychopathology, are germane.
The Journal concentrates on work with human subjects, but may consider work with animal subjects if conceptually related to issues in human biological psychology.
