The siren's call: Exploring the impact of female voice pitch on male risk-taking behavior

Risk-taking, defined as undertaking actions with potential negative outcomes in pursuit of greater rewards, has shown gender-specific patterns, often heightened in males by mating-related cues. Previous research has primarily focused on visual attractiveness indicators such as facial features and body ratios, while the impact of auditory cues like female voice pitch, linked to attractiveness and fertility, has been underexplored. Moreover, the interaction of cultural factors with risk-taking behavior remains insufficiently examined. This study investigates how female voice pitch affects male risk-taking behaviors, combining evolutionary and cultural insights, and uses virtual reality to enhance ecological validity by simulating real-world scenarios. Two experiments were conducted at a university in Shanghai. Experiment 1 used virtual reality to simulate a "The Stoplight task" game, finding that higher female voice pitches increased male risk-taking. Experiment 2 introduced a cultural dimension, revealing a significant interaction: in cultures promoting risk-taking, high-pitched voices led to the highest risk-taking, while in more conservative contexts, they prompted the least. The results suggest that both evolutionary traits and cultural settings shape risk-taking behaviors. This has practical implications for areas like navigational voice design and mate selection guidance.
