Structured PICO

Population

26 undergraduate students (13 dyads), mean age 24.08, 14 women. Right-handed, normal visual acuity, no history of psychopathology.

Intervention

Reinforcing external feedback (manipulated to induce positive perceived self-efficacy) during a cooperative joint task (synchronicity game)

Comparator

Pre-feedback condition (performance before receiving the manipulated feedback)

Outcome

Intra- and inter-brain functional connectivity (measured by fNIRS) and behavioral performance (Response Times and Error Rates)surrogate

External reinforcing feedback during a cooperative task improves behavioral synchronization and increases inter-brain connectivity in the dorsolateral prefrontal cortex.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

Reinforcing feedback may boost joint performance via inter-brain links; leaves open causal mechanisms and applicability beyond lab dyads.
