Abstract Junger et al. (2018) conducted a preregistered study examining whether women particularly prefer muscular bodies when conceptive in their cycles. Despite an impressive number of participants and within-woman observations, they found no evidence for a preference shift; rather, they claimed, conceptive women find all male bodies more attractive. We preregistered a separate study very similar to Junger et al.'s, with specified analyses focusing on shifts associated with joint additive effects of log-transformed estradiol and progesterone (ln(E/P)). We performed similar analyses on Junger et al.'s publicly available data, using an empirically vetted (though not preregistered) measure of Strength/Muscularity. They revealed a ln(E/P) × Strength/Muscularity × Relationship Status interaction effect on sexual attraction. The ln(E/P) × Strength/Muscularity interaction ran in opposite directions for partnered and single women effects largely driven by P levels. Junger et al.'s null conclusions and claims about general preferences are premature. We offer several observations regarding preregistered analyses.

心理周期转变 redux：重新审视一项预先注册的研究，检查对肌肉的偏好

摘要 Junger 等。(2018) 进行了一项预先注册的研究，检查女性在受孕时是否特别喜欢肌肉发达的身体。尽管参与者和女性内部观察的数量令人印象深刻，但他们没有发现偏好转变的证据。相反，他们声称，受孕的女性发现所有男性身体都更具吸引力。我们预先注册了一项与 Junger 等人非常相似的单独研究，其特定分析侧重于与对数转换雌二醇和黄体酮 (ln(E/P)) 的联合累加效应相关的变化。我们对 Junger 等人的公开数据进行了类似的分析，使用经过经验审查（尽管未预先注册）的力量/肌肉强度测量。他们揭示了 ln(E/P) × 力量/肌肉 × 关系状态对性吸引力的交互作用。ln(E/P) × 力量/肌肉力量的交互作用在很大程度上由 P 水平驱动的合作和单身女性影响的方向相反。Junger 等人关于一般偏好的无效结论和主张为时过早。我们提供了一些关于预注册分析的观察结果。
