Introduction: Prosocial risky behavior (PRB) proposes that individuals take risks for others' benefits or social welfare, and that this may involve trade-offs between risk and social preferences. However, little is known about the underlying cognitive mechanisms of risk-seeking or aversion during PRB.
Methods: This study adopted the dilemma-priming paradigm to examine the interaction between the risk levels of personal cost and situational urgency on PRB (Experiment 1, = 88), and it further uncovered the modulation of the risk levels of failure (Experiment 2, = 65) and peer presence (Experiment 3, = 80) when helping others.
