Perceptions of mate poaching predict jealousy towards higher-pitched women’s voices

Previous research has found that higher-pitched female voices elicit jealousy among women. However, it is unknown whether jealousy towards higher-pitched female voices is driven by perceptions of the rival’s mating strategy or by beliefs about the speaker’s attractiveness to one’s romantic partner. In addition, the degree to which higher-pitched female voices elicit jealousy could be associated with variation in trait jealousy among women listeners. Here, I manipulated women’s voices to be higher or lower in pitch, and tested whether variation in jealousy towards female voices was more strongly associated with perceptions of mate poaching, beliefs about the speaker’s attractiveness to listeners’ romantic partner, or with individual differences in trait jealousy. I replicated findings that higher voice pitch elicits more jealousy from women, which was positively associated with perceptions of mate poaching. I found no evidence of an association between trait jealousy and any voice-based perception. The findings suggest that perceptions of a target’s proclivity to mate poach better explain the jealousy-inducing nature of higher-pitched female voices than do beliefs about the speaker’s attractiveness to one’s romantic partner.
