进化心理学家假设，男性比女性更容易对性不忠感到不安，而女性则比男性更容易对情感不忠感到不安。另一方面，性想象假说认为，不忠反应的性别差异源于男性明确的性意象。基于后一种假设，我们假设，尽管男性会比没有稳定关系（NCR）的女性对性不忠感到更痛苦，但在稳定关系（CR）中没有性别差异。这两种假设分别用598名CR参与者和1643名NCR参与者进行了检验。CR组的性不忠反应没有显著的性别差异(d = 0.008，幂为。956)，而在NCR组中，男性比女性对性不忠更不安。性别与不忠类型之间存在显著交互作用，而性别与不忠类型之间不存在显著交互作用（偏η2 = 0.005，幂为0.943）。我们的研究结果支持性想象假说，但与EJM假说不一致。
Evolutionary psychologists hypothesized that men are more upset by sexual infidelity than women are, whereas women are more upset by emotional infidelity than men are. On the other hand, the sexual imagination hypothesis states that gender differences in infidelity responses are derived from explicit men’s sexual imagery. Based on the latter hypothesis, we hypothesized that although men would report being more distressed by sexual infidelity than women who were not in a committed relationship (NCR), no gender difference would be reported in a committed relationship (CR). These two hypotheses were tested with 598 participants in a CR and 1,643 participants in a NCR. No significant gender difference was found sexual infidelity response in the CR group (d = 0.008, a power of .956), whereas men were more upset than women about sexual infidelity in the NCR group. Moreover, a significant interaction between gender and infidelity type was found in the NCR, whereas no significant interaction between gender and infidelity type was observed in the CR group (partial η2 = 0.005, a power of .943). Our findings supported the sexual imagination hypothesis but were inconsistent with the EJM hypothesis.
