Summary
Couples using a delayed response strategy in a cooperative task showed better performance and stronger interpersonal brain synchronization (IBS). This strategy may enhance cooperation by unifying response modes and synchronizing neural processes.
Area of Science:
- Neuroscience
- Social Psychology
- Behavioral Economics
Background:
- Cooperation relies on interpersonal brain synchronization (IBS).
- Individuals utilize diverse strategies during cooperative tasks, such as immediate or delayed responses.
- The impact of these strategies on cooperative behavior and neural synchrony is not fully understood.
Purpose of the Study:
- To investigate how different cooperative strategies influence task performance and interpersonal brain synchronization (IBS).
- To explore the neural mechanisms underlying strategy selection in cooperative tasks.
Main Methods:
- Recruited 43 married couples for a simultaneous button-press cooperative task.
- Recorded interpersonal brain synchronization (IBS) using functional near-infrared spectroscopy (fNIRS) hyperscanning.
- Introduced a "cooperation coefficient" to quantify cooperative behavior.
Main Results:
- Couples employing a delayed response strategy outperformed those using an immediate response or no strategy.
- Stronger IBS was observed in the right frontal cortex under the delayed response condition.
- Higher perceived parenting stress correlated with better task performance, stronger IBS, and a tendency towards delayed response strategies.
Conclusions:
- The delayed response strategy may facilitate cooperation by unifying response patterns and synchronizing cognitive and neural processes.
- This study provides neural evidence linking specific cooperative strategies to behavioral outcomes and brain synchronization.
